Update 9/4/20. “Refind your prime” and “Take back what time has taken.” These are two statements made for Mdrive, the supplement for men that’s touted to “naturally increase free testosterone.” Does Mdrive work? More importantly, does Mdrive increase testosterone levels —naturally? That’s one of the questions I want to try to address in this Mdrive Review.
What Does The Name Mean?
I think Mdrive is short for “man drive.” That is a guess. Take it for what it is.
Who Makes Mdrive?
On the Mdrive website (MdriveForMen.com), I see that Mdrive is made by a company called Dream Brands.
The address of Dream Brands is 11645 N Cave Creek Rd. Phoenix, AZ 85020. This address shows a house that has been converted to an office and production facility. The Better Business Bureau file gives DreamBrands a rating of “A +”. See the BBB file for updates and more information.
Mdrive TV Commercial
Here is a TV commercial from their YouTube channel. I have to admit it's pretty good.
Mdrive vs Mdrive Plus
There are 2 types of Mdrive:
and
2. Mdrive Plus
What's the difference? Both Mdrive Classic and Mdrive Plus contain the same main proprietary blend of ingredients that I'll review below. Mdrive classic has 1325 mg of the blend while Mdrive Plus has 1130 mg.
Another difference is that Mdrive Classic only has vitamin B12 in addition to the proprietary blend.
Mdrive Plus, on the other hand, has several other vitamins and minerals. Other than that, I don't see any difference.
If you saw the Mdrive TV commercial, you might notice that the commercial actually refers to Mdrive Plus, so this will be the product that I review.
Update. Mdrive Plus may be discontinued. It's no longer listed on the product's website.
Mdrive Ingredients
According to the Mdrive TV commercial (you can see it on Mdrive4Men.com), Mdrive is composed of something called “Cordydrive” plus “5 clinically tested ingredients.”
These are the 5 clinically tested ingredients
| Ingredient | Function of ingredient (according to Mdrive TV commercial) |
| 1. Testofen | free testosterone support |
| 2. Setria | detox |
| 3. L optizinc | cell support |
| 4. Selenium Select | immune support |
| 5. Chrome | glucose support |
Mdrive Plus contains 1150 mg of a proprietary blend of these ingredients.
Let's now look at the research for Cordydrive and the 5 clinically tested ingredients in Mdrive and see what we can discover.
Cordydrive
This is said to be the primary ingredient in Mdrive. Cordydrive is a made-up word for Cordyceps (Cordyceps Sinensis). Cordyceps is a type of mushroom. Another name for it is “caterpillar fungus.” Cordyceps appears to have no human proof it raises testosterone. Likewise, human aphrodisiac properties were not located either.
Cordyceps and Exercise
So can cordyceps help you exercise better? Let's look at the evidence.
Study
In one study cordyceps failed to improve muscle endurance, muscle strength, or muscle power in healthy men. The men were given 350.8 mg of cordyceps, which was used in conjunction with other herbs.
Study
In another investigation, cordyceps did not improve aerobic exercise endurance when it was given to 22 male cyclists for 5 weeks. People in this study received 3 grams (3000 milligrams) of cordyceps per day (this is more than is in Mdrive).
Study
In this study, 17 cyclists were given 1000 mg a day. The supplement did not improve bike riding performance.
Study
Runners may have heard this herb improves VO2max (aerobic capacity). At least one study has noted it did extend the time until execution occurred when it was given to 8 men who rode a stationary bike as long and hard as they could.
To be fair, cordyceps exercise studies seem to suffer from small studies that don't last very long.
See the Shakeology review for additional information.
Cordyceps And The Immune System
There are several studies showing that cordyceps appear to stimulate the immune system in mice as well as in test tubes.
Human cordyceps research on immunity appears to be limited to test tube research for the most part. It might stimulate the immune system or might not. I just don't know.
The 5 Clinically Tested Ingredients
1. Testofen
This is an invented word used to refer to the herb, fenugreek. Research generally uses 600 mg per day (they don't tell us how much fenugreek is in Mdrive).
The Mdrive TV commercial says this Testofen is for “free testosterone support.” This is then followed by these words “based on Gencor Testofen clinical.” Gencor Pacific Group is the company that makes the Testofen brand of fenugreek.
The US headquarters of Gencor is located at 920, E.Orangethorpe Avenue Suite B Anaheim CA – 92081.
There were 3 studies listed on the Testofen website.
Here they are:
1. A rat study Since men are not rats I'll discount this study.
2. A human exercise study. In this study, Indian researchers gave 60 young men 600 mg of Testofen or a placebo for 8 weeks. They also performed strength training exercises to muscle failure. Free testosterone increased from 17 ng/dl to 35 ng/dl. Body fat was also said to decline significantly.
3. A human study where men who were given Testofen basically reported how they felt on questionnaires. No changes in testosterone were noted.
So, the evidence for Testofen appears to be :
1. a rat study.
2. One study showing Testofen works.
3. a study where Testofen does not raise testosterone levels but yet appeared to work when men self-report how they feel on questionnaires.
For more on testofen see:
2. Setria
This is an invented name for glutathione, a natural antioxidant. Glutathione is in fruits and vegetables and exercise increases glutathione naturally.
Setria is a reference to a proprietary type of glutathione made by a company called Kyowa (Kyowa-USA.com). Mdrive says Setria (glutathione) is for “detox.”
3. L-OptiZinc
This is a name for a proprietary form of zinc. It’s the mineral zinc bound to the amino acid methionine. This is likely done so as to increase zinc absorption.
Mdrive contains 100% of the daily allowance of zinc. I'm guessing that Mdrive has this mineral because a lack of zinc can reduce testosterone levels.
But, do zinc supplements raise testosterone? Right now I'm on the fence about this. One study noted that 30 mg of zinc given to male cyclists for 4 weeks did raise free testosterone levels. The amount given was more than the RDA for zinc.
I couldn’t find much zinc-testosterone research on humans so I am not sure what degree zinc raises testosterone – or even if it really does – if you are already getting enough. It's not hard to get zinc in the diet (even easier if you take a multivitamin) so I don't think most men are lacking in this mineral.
4. Selenium Select
This is just a proprietary type of selenium used in supplements. Like zinc, selenium is also needed to make testosterone. In the study of zinc and cyclists mentioned previously, selenium was also given. For what it's worth, Zinc raised testosterone more than selenium.
5. Chrome
They also call this “Zychrome” on the Mdrive website. Both names refer to the mineral chromium. Mdrive Plus contains 333% of this trace mineral. Why? Chromium can help us process sugar better and that’s good but, people who are taking Mdrive are probably already health conscience and hence, are not likely deficient in this mineral. For more on this see my Chromium review.
Other Ingredients in Mdrive
Maca
Also called Lepidium meyenii. One study noted that Maca improved sexual desire when used at a dosage of 1500 mg – 3000 mg per day for 12 weeks (this is more than is in Mdrive). Maca did not raise testosterone levels in this study. Another study also noted no change in testosterone or other hormones following Maca use.
Here is a Macca supplement on Amazon that has several positive comments.
American Ginseng
Also called Panax quinquefolius. The Mdrive website says ginseng is used for “mental energy and sharper focus” although I can't find any good proof it does either of these. I did locate one ginseng exercise study from 2005 but this study noted that ginseng did not help aerobic exercise ability.
Damiana
Also called Turnera diffusa. The Mdrive website says damiana is used to “manage stress.” But they don't tell us what kind of stress they are referring to. For example, is it:
- physical stress?
- emotional stress?
- oxidative stress?
So, I searched the National Library of Medicine for these keywords:
- “Damiana stress”
- “Turnera diffusa stress”
I could not locate any studies on daminia helping / reducing stress. The only study that looked remotely like it might fit this description was a rat study noting that damina might reduce ulcers.
Vitamin B 12
Mdrive has 2000% of the daily value of vitamin B12. Those at risk for B12 deficiency include
- vegans
- older folks
- diabetics (metformin depletes B12)
- alcoholics
Unlike most other water-soluble vitamins, we store B12! Healthy people can have 1-2 years' worth stockpiled.
Contrary to what energy drink makers may say, there's no proof vitamin B12 boosts energy unless you are deficient in it, to begin with. Likewise, it's also a myth that vitamin B12 helps weight loss also.
Maitake Extract
What extract do they use? They don't tell us. Maitake comes from mushrooms. Its scientific name is Grifola frondosa.
The Mdrive website says Maitake “supports immune health.” In a small 2003 study, maitake extract stimulated natural killer cell activity and slowed tumor progression in 10 cancer patients.
In a 2009 study published in the Journal of Cancer Research and Clinical Oncology, a maitake extract stimulated the immune system of 34 breast cancer patients. This study noted that maitake extract stimulated some aspects of immunity while depressing other aspects.
If you have cancer, please speak to your oncologist first before experimenting with maitake extracts. Again, you have to ask yourself what maitake extracts help cancer? Buying maitake supplements at health food stores may not be giving you the extracts that cancer research has used.
Coleus Forskohlii
A lot of weight loss supplements contain Coleus forskohlii and even Dr. Oz has talked about it. It's in many other supplements including :
The way it's supposed to work is by stimulating fat-burning enzymes. It sounds interesting but there are problems with some of the studies.
For example, some research notes that coleus forskohlii does not increase metabolism or raise testosterone levels. Also, not all research finds that coleus helps with weight loss.
For more in-depth information on the coleus research, read my coleus forskohlii and weight loss review.
Here is a coleus forskohlii product on Amazon that has several positive comments.
Ashwagandha
The scientific name for this herb is Withania somnifera. There is some very preliminary research on Ashwagandha and arthritis, noting that it might help protect cartilage (and hence reduce the risk of osteoarthritis). Ashwagandha seems to have anti-inflammatory properties also.
In a study published in 2010 in the International Journal of Ayurveda Research, Ashwagandha was shown to improve:
- aerobic ability (VO2max)
- sprint velocity
- lower body power during vertical jumps
in young men (who did not exercise) after 8 weeks of daily use. The amount of Ashwagandha used was 500 mg (I don't know how much Ashwagandha is in Mdrive).
Here is an Ashwagandha product on Amazon with several positive comments.
Note. This study used young men. Mdrive is marketed to men over 40.
This study contained 40 young men. Yet only 10 men received a placebo. The other 30 men received herbal treatments. Why didn’t the researchers randomly assign the herbal treatments? This could be a weakness of the study.
Ashwagandha is also found in several other supplements I've reviewed before including:
- 1 Db Goddess – a female weight loss supplement
- Avesil – a weight loss supplement
- Shakeology – a weight loss/health drink
Here is a scientific review of Ashwagandha that was published in 2000 in the journal Alternative Medicine Review for those who want to know the chemistry etc. of this herb.
Bioperine
This stuff is used to increase the absorption of supplements. It's been used in other products I've reviewed including The testosterone booster Syntheroid and the weight loss supplement Lean and Fab.
How to Contact Dream Brands
A phone number of 1-888-340-9181 is listed on the website for those who want to contact them and /or want to “Ask our Experts” a question.
Does Mdrive Raise Testosterone?
I could not find any research showing that Mdrive -itself – raises testosterone levels in humans.
Who is Doctor Stephen Morganstern?
The Mdrive testimonials page shows a video endorsement from Stephen Morganstern, MD. He is a urologist in GA and the author of books about the prostate, and impotence. His website also notes that Dr. Morganstern is a Body by Visalus distributor too.
In his testimonial Dr. Morganstern says:
“I have not seen a product like Mdrive on the market…”
Really Dr. Morganstern? While the ingredients are not identical, Mdrive has ingredients that are similar to other products that I've already reviewed.
Dr. Morganstern goes on to say:
“The combination is excellent. It takes the science that we have available today and combines all the natural ingredients for an excellent presentation to the patient that is safe and efficacious.”
It would take clinical studies to prove the supplement is efficacious at raising testosterone levels.
How Long Until Mdrive Works?
The Mdrive website says “Most people report feeling energized all day long within the first couple days.” But, then they say …
“Each person's biology is different but most gradually start to notice the effects of increased testosterone including, focus, strength, endurance, respiration and healthy libido.”
My thoughts:
1. I disagree with the claim “each person's biology is different.” Since we are all humans we all work pretty much the same way.
2. They say most people “gradually” start to notice the effects of increased testosterone…. How long is “gradually?” Is it a week,? A month? Six months?
How Much Does Mdrive Cost?
On the Mdrive website, they list $59.99 for 60 capsules of Mdrive Plus and $44.99 for Mdrive Classic. Since they recommend 2 capsules per day, this is a month's supply. While Mdrive Classic appears to be available at several health food stores, they do say that Mdrive Plus is only available online.
There is a 60-day money-back guarantee on Mdrive for those who want to return it. People just have to pay to have it returned to the company. For more information call the Mdrive company at 888 340 9181.
Mdrive Side Effects
In healthy people, I think Mdrive is Safe. I'm not aware of any negative side effects. That said here are some things to consider when using this supplement. this list is not complete.
- Start with less than suggested for the first two weeks to see how you respond
- Stop taking Mdrive at least 2 weeks before surgery
- Avoid if pregnant or breastfeeding
- Speak to your pharmacist if you take any medications
Ginseng might lower blood sugar levels. This might not be noticed by healthy people but in diabetics, there may be an interaction with diabetes drugs.
Ashwagandha might overstimulate the thyroid gland. This comes from a case report of a woman who developed symptoms of hyperthyroidism after using a supplement that contained Ashwagandha. The symptoms disappeared after she stopped taking it. There is lab animal research hinting that Ashwagandha might elevate thyroid hormone. I can't locate any human research on this though.
If cordyceps stimulates the immune system, in theory, it might be inappropriate for people with autoimmune issues like hypothyroidism (Hashimoto's disorder), and other autoimmune disorders.
Does Mdrive Work?
I didn't try Mdrive, so I don't have any firsthand experience with this product. Remember Mdrive itself doesn’t seem to have any published peer-reviewed proof that it raises testosterone. That doesn’t mean it doesn’t work though. When trying any testosterone supplement, it may be wise to first get your testosterone levels checked. Then try the supplement for a month. Then check your testosterone levels again. This would be the easiest way to know for sure if Mdrive works or not.
I’m a skeptic, but I’ve been feeling so horrible for such a long time (mostly due to anemia) that I was willing to try anything. I headed down to the GNC and ended up with M Drive. Amazing! I haven’t felt this good in 18 months. At the same time, I also started taking a daily iron supplement to help with the anemia, so I wasn’t sure which was helping.
It could have just been the iron, but after the month supply was over, I continued to take the iron and my energy/libido/outlook crashed. It looks like I will be reordering.
Mark, thanks for sharing that. I hope you continue to feel better with it.
I started using M-Drive Elite about three months ago, and I swear by it. The product has literally changed my life.
I started taking it after the recommendation from the manager of a local vitamin/supplement shop. I had explained that I was consistently feeling run down, despite getting good night sleeps, eating fairly well, and exercising regularly.
After taking M-Drive for about 3 days I could already feel the difference. The tired, run down feeling that I lived with consistently for year was gone. I was now going through the day feeling alert and sharp. My exercising became far more efficient, and my muscle recovery was increased, particularly in my legs.
I am 47, average weight for my age, and exercise regularly. My T levels were normal (for my age range) prior to taking M-Drive. I have not had them retested since.
Hi Keith, thanks for sharing. I’m happy that you are finding benefits from M Drive.
Cordyceps: CTM is very old; however, the dosage is usually sub-pharmacologic and it is more a lifestyle than pill for ailments or instant health….many experiments…no real evidence based proof….some need hot water to chemically change once harvested, etc….doubt pill ingredient any good.
Fenugreek seemed to work in Wistar rats. Worked in human resistance training.
I started taking MDrive Orignal formula, soon I started noticing a hangover/migraine like headache in the morning. I decreased to one a day instead of two and still had the headaches. I was disappointed because I was noticing relevant changes in my overall sense of being, probably not enough time to see the other expected improvements for sure.
After less than two weeks I reluctantly returned them, but I really didn’t want daily migraine/hangover level headache either. Now I’m just searching for a replacement, but also taking many of the ingredients individually found in M Drive.
I’m 51 w/low T and some libido/ED. I had recent blood work done to confirm T levels. I have tried sildenafil ( Maxifort) & tadalafil (Cialis) before so I had a good idea of the general effects of these types of drugs for ED. I also have tried anabolic steroids/synthetic testosterone, as well as, other herbal T boosters with amino acid D-aspartic acid (DAA) & fenugreek.
After taking two each day for the past few days I have not noticed any increase in energy. However, I had sex last night and it was the first time during my trial period of MDrive. Truthfully, I was surprised & shocked at how similar the increase in blood flow & stiffness of erection were to the drugs.
It may have been a fluke but I will continue to use the remainder of this product to test the results. I am having my blood tested for T levels again next week. I am very skeptical about any claims regarding boosting T levels. It seems without straight injections to replace testosterone, nothing has long term effects but the boost of libido & sexual performance seems very effective for me personally.
Hi Kelly, thanks for sharing that. Please do let us know what your new testosterone results are when you get it tested next week.
Well I was thinking mdrive was all hype. May be starting to believe otherwise. My husband is 29 and hasn’t had an erection(one that lasted) for over 4 months because of low t. On the 2nd night he had one pretty amazing erection. Not sure at this point if it was pure coincidence or if it actually worked but he will continue to take it until the month is up and see how it goes. He doesn’t report any change in energy but does in libido.
Hi Kay, why are they saying your 29 yr old husband has low testosterone? Just curious. Thats pretty unusual for someone so young? Do you know what your husbands testosterone level was?

Hi Eric, thanks for the study. might you have a pdf of the study so I can read it?
Hi Joe,
I unfortunately do not have free access to that journal. I will try to get to it via other means but in the mean time I don’t.
Best,
Eric
Hi Eric, thanks, I will try to get to the library and try to find it also.
Stuff doesn’t work…at all…nothing
My two cents; I have used this product for several months and have done before and after blood work. Being that I have made no other changes, the blood work would seem to confirm that it does increase testosterone levels. I was low normal prior to use and am now high normal.
Subjective observations include an increase in skin oil production and erection frequency/sex drive. It’s not like steroids which I have also used but I would say it beats using the patch for those who have ‘low T.’i
PJ, Few questions. How old are you? What were your testosterone levels before and after MDrive? Did you lose any weight?
Joe, I am 38, levels pre supplement were around 0.3. Post supplement, around 0.9 to 1, (can’t find my labs but that’s what I remember.) No weight loss noticed but I do have a low thyroid and have to take a replacement hormone which probably skews things a little.
PJ, thanks for the follow up 🙂
There’s research to support Paul’s enthusiasm for Coryseps’ effects at altitude (being used by by Tibetin Army and Sherpas). See: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3770031/
Rudi, thanks for the study. It looks like a test tube study but it did use human cells so that’s good.
I’m believing that any supplement that could have a truly significant impact on health issues (testosterone, hair restoration, etc.) would have a relatively robust strength – meaning it would most likely NOT be an over the counter item. I think that products like this may have the potential to provide a “positive contribution” to your general physical health but are more hype than anything.
I believe that any commercially available product that can counter common age related issues would need no advertising – word of mouth and a reputation for proven results would have people lined up around the block to buy the product. So far, I have not noticed any of these types of products to have a rabid fan base. Personally I think you could instead spend the money on a gym membership and do more for your stamina, physical shape and mental alertness.
James you make an interesting point about none of the products of this ilk having a rabid fan base as you say. I likewise have not noticed any specific product stand out from the rest. I do agree that a gym membership -for those who dont have one – or working out at home is a good idea as well.
Awesome review….
It really helped me clear up a few things but now confused, all I want is a good multi vitamin with some benefits and M drive doesn’t seem to be it!
Now they have M drive elite another big rip off I presume. I got a box as a gift, I’m going to give it a try and keep you informed on any improvements…..
Fingers crossed or I will be sending this box back too.
Kelvin thanks I appreciate that. I didn’t know about M Drive Elite. Yes, do let me know what happens if you try it.
Good review. why didn’t he use the product and test his own testosterone to see if it would work for him. this would have been a more accurate review.
David, if I tested everything I reviewed Id go bankrupted and I really don’t want to make my body a Guinea pig for everything that I hear about. How about this – why didn’t the company provide any proof that Mdrive raised testosterone levels in people? if they had, I might have tested it.
I lost my ‘mojo’ after taking propecia for about two years. After one year of being propecia free, mojo still has not come back… The other day I was browsing the sale rack at local drug store and saw M Drive on sale (might have been a return). It doesn’t say classic or plus and it has the nane ‘Ocean Naturals’ on it but it does have ‘Mdrive4men’ on it. I think it was $15 (75% off or something). Being desperate for a cure, i bought it. Totally gross tasting but on day 2, I swear to god, major return of mojo! On day 3 I went to bed with an erection for the first time in years. Only thing is so far each day I’ve gotten a headache in the eve which I think is because of the ginsing… So, not sure if it increases testerone, strength or muscle or anything else but I can tell you it definitely has, so far, brought back my sex drive (after propecia destroyed it). I also think it helped my focus (got lots done at the office yesterday… Coincidence, I don’t know…). Unfortunately though I think I need to find another version of this without the ginsing as I don’t think I can handle the headaches… Happy to hear suggestions.
Jeff, that’s interesting thanks for sharing. As far as I know there isn’t a type of Mdrive without ginseng.
I have to say as a Pro mtn bike racer and new to M Drive I feel this stuff works it has had a positive results training and racing the past month.
Don’t want to do hard training days or races with out it. 25 yeas as a racer and don’t think there is just some natural magic pill that just makes you faster and recover quicker. But so far so good I like this product..Just one more thing I have add to my training program. I guess me as a human guinea pig I’ll see how it works overtime.

Thanks Joe-M Drive CEO, for the new ELITE has elected KSM66 as it’s source for Ashwaganda, it was just awarded Botanical of the year at the Expo West In Anaheim California just days ago. In proper and plenty dosage, it’s a very interesting and effective botanical, in our world of athletes, it’s affects are VERY sought after.
I feel it’s important to know and comment ( and I’m stepping aside from the athlete speaking) but for ALL the commenters above to know that a supplement such as M Drive (and all others in this category)…is and MUST be accompanied by an active lifestyle and given the proper testing situation.
To get the box from the post office, drop some capsules, and to sit and watch Sports Center and expect some great T response is completely pointless. The endocrine system and all others have got to be moving along with a good metabolism. M DRIVE Does speak to T, but will NOT solve all low T issues (nor ever makes those claims), it will compliment a good lifestyle, this I can guarantee. The formula has a synergistic affect…would love to get you on this Joe and hit the trails with ya and see what ya think. I could send you some from my personal batch if you’d like!
Appreciate the great forum to express.
Off to the trail.

Paul, I would agree that diet and lifestyle change are important. As a research “geek” I would love to see an Mdrive vs Mdrive + diet and lifestyle study to contrast any effects that might occur. This would be a great thesis /dissertation product for any grad students reading these words.
Appreciate the offer Paul but I’m sure I’m not in your class Mdrive or not. I’m one of those guys who has a mountain bike but who never takes it off road 😉
Paul Romero here- full time ultra endurance athlete/competitor and fellow supplement geek-
Just had a good cup of coffee so i’m gona blab a little bit.
Just some commentary in support of M Drive and their incredible integrity as people, lab and products. Super cool, smart, determined people that stop at nothing to put the best ingredients into their products, sparing no expense.
Remember, Cordyceps, is never spoken as a T booster, it’s for improved oxygenation/aerobic capacity. Well known in the endurance community.
Used Cordyceps off/on for 14 years- When you are on it, and you test your TOP end, you KNOW you’re on this product. It’s quite impressive. Endurance athletes- TRY it if for no other reason.
Cordyceps has been used by Tibetin Army and Sherpas for so many years to increase aerobic capacity- at 15-18,000′ …. Those folks aren’t dummies, I’ve been on the trail with them.
Ashwaganda- coming in at proper good dosage- HOLY CRAP- JUST one mans opinion, NO lab results from ME to prove this, but THIS will be the most talked about extract in the nutrition world in the next few years.
IT’s Incredible- I’m calling it the ZEN Endurance Weapon. I’ve raced, Ultra Marathons with this, with the all new (soon to come) M Drive ELITE, and IT’s EFFECTIVE. I can NOT race or do ultra training w/out.
I’ve had the honor of meeting the scientists from India that grow the highest concentration full spectrum root-extract available on the market today, with the clinicals to back it up. Take it for what it’s worth, but it’s clinically documented to decrease stress and anxiety and boost memory and cognitive function. It’s a VERY good feeling when taking this extract.
Remember through ALL this talk about Test levels-
It is not necessarily the total testosterone level that matters, rather it is the amount of Free-Testosterone that really makes a difference – the amount of testosterone you have circulating in your blood stream and is bio-available for your body to utilize. Free-Testosterone is a key component your body ACTUALLY uses for strength, stamina, endurance, vitality and sex drive. Mdrive helps to increase your Free-Testosterone
Thanks for your time-
Stay classy and stay PROPERLY INFORMED.

Paul, appreciate your words and the scientific approach you take to coaching other athletes. I would agree that its not all about testosterone but tended to focus a lot on testosterone as I felt that was a main focus of Mdrive marketing. I still feel the best way to know for sure if anything changes is to test testosterone before and a month after a product – I feel both free and bound testosterone would be good to measure.
As for Cordyceps, I also have been aware of it for a while as it pertains to aerobic exercise events. I did link to studies noting that it was ineffective at improving this aspect of training, but I admit this may be due to the limited good studies done on it.
Like you, I am also looking forward to reading more research on Ashwaganda. Its becoming quite popular in some exercise and health supplements Ashwaganda.
