Have you heard of Prolongz? I didn’t before I saw an infomercial for the product late one night. Prolongz, a product of the Advanced Men’s Institute, is supposed to help men in the bedroom last longer during sex by way of something called “strip delivery technology.” Even though the infomercial I saw looked pretty cheesy, I decided to take a look in case others saw the commercial and wondered if it worked or not. So in this Prolongz review, I'll look not only at the supplement but at the company too. Along the way, I’ll also see if there is any research on Prolongz because this is the best way to see if it works or not.
Who Makes Prolongz?
The Advanced Men’s Institute is the company mentioned on the TV infomercial I saw. Another name for the company is Prolongz LLC. Interestingly, I did not see a website for “Advanced Men’s Institute.” When I searched Whois.com – a site that provides information about websites – I discovered that Prolongz.com was created on January 3rd 2013.
Advanced Men's Institute became incorporated in California in 2014. The Better Business Bureau gave Advanced Men’s Institute a rating of “A-“ as of 11/3/14. The company is also a BBB-accredited business (that's good too). Do read the BBB report as ratings sometimes change.
If you saw the TV infomercial (titled “Last Longer in the Bedroom”) you saw many people with Australian accidents giving testimonies about how Prolongz worked. The Prolongz website also states that AMI has been treated and counseled over 500,000 patients in Australia.
So I googled “AMI Australia” and located a company called “Advanced Medical Institute.” They also call themselves “AMI” and also market an “Oral Strip Technology” for premature ejaculation. Their website is amiaustralia.com.au.
This sounds a LOT like the “Strip Delivery Technology ” that's said to be at the heart of Prolongz.
Based on this, I think AMI (Advanced Men's Institute) and AMI (Advanced Medical Institute) are the same company. One difference between the companies is that in Australia, Advanced Medical Institute mentions both men and women. With Advanced Men's Institute, the focus is only on men.
How To Contact Prolongz
On the Terms and Conditions page of Prolongz.com/AMI we see that the address for the company is 1420 N. Claremont Blvd #111A Claremont, CA 91711.
The Terms and Conditions page of the website also states that their corporate office is located at
250 W 1st Street, Ste 310 Claremont CA 91711. The Terms and Conditions page of the Prolongz website lists 909-451-0753 as the phone number to their corporate office.
Each box of Prolongz contains 1 month's supply. That is 20 strips per container. There are 3 containers per box (60 strips total). I serving size is 2 strips. Prolongz has the following ingredients in 2 strips:
|Damiana extract||10 mg (no DV established)|
|Ginseng extract||10 mg (no DV established)|
One thing I will mention is that they don't tell us which extracts of daminia and ginseng they are using. That makes reviewing this product difficult since each herb can have multiple “extracts.”
As for ginseng, as I mentioned in my book on supplements, there are basically 3 types of ginseng used in supplements:
1. American ginseng
2. Asian ginseng
3. Siberian ginseng
What type is in Prolongz? They don't tell us. Again this makes reviewing Prolongz difficult.
Both daminia extract and ginseng extract make up a “proprietary blend.” Interestingly, fenugreek seed extract is not part of the proprietary blend, but rather stands apart on its own on the product label. This makes me wonder if fenugreek is the main ingredient in Prolongz.
The label lists “Other ingredients” also in Prolongz. These are not active ingredients and are as follows
- Pullulan – a type of starch (polysaccharide)
- Pepperment extract
- AK sugar (I don't know what the AK refers to)
- polyglycerol fatty acid esters
The Prolongz.com website shows no clinical evidence that the product-itself – does what they say. The infomercial gave testimonials from people although without peer reviewed research on Prolongz itself, we don't know if it works or not.
The idea behind Prolongz – if I understand it correct – is that it's supposed to “prolong” the time before ejaculation occurs. This is very different than other products such as :
- Androzene (click to read my review)
- Cyvita (click to read my review)
which are marketed to improve erections
Likewise Prolongz also appears to be different than :
- Ageless Male (click to read my review)
- Nugeinx (click to read my review)
Which are touted to raise testosterone levels
With that in mind, is there any good proof that Prolongs extends the time before climax occurs in men?
Unfortunately, when I looked the Prolongz website I did not list any clinical trials on the product.
Also, when I searched the National Library of Medicine, a database of millions of studies from around the world for the word “Prolongz” I didn't see any relevant studies showing up either.
Lastly, googleing the word “Prolongz Research” did not turn up any clinical studies.
This all says to me that Prolongz -itself – has no published peer reviewed research to say it actually works.
Lack of research does not mean it doesn't work however. It's possible that the ingredients in Prolongz, either working alone or in combination, may result in longer erections.
With that in mind, I began my search. I found the following relevant investigations
In 2001, a study was published titled A double-blind placebo-controlled study of ArginMax, a nutritional supplement for enhancement of female sexual function. This study involved 77 men AND women. Basically 34 people received a supplement called ArginMax and 34 people received a placebo.
Results: After 4 weeks, 75% of people getting ArginMax reported improvements in sexual function vs. 31% in the placebo group.
While encouraging, ArginMax is not Prolongz. The ingredients are not the same.
Here is ArginMax on Amazon for those who want to see more about it
I've heard of some evidence that Panax ginseng -used topically – might help premature ejaculation. But I've never heard that taking it orally helps. Again, if I knew what type of ginseng was in the product, I might be able to say more.
Fenugreek is popular in male enhancement supplements although when I tested it on myself, I didn't notice much of a difference. The label for Prolongz does not tell us how much fenugreek it has. Rather, it only tells us that the fenugreek extract comes from the seeds (that's good) and that its standardized to 50% fenuside.
The word “Fenuside” is a trademarked name that was created by the company called “Gencor Pacific, the maker of a very popular fenugreek extract called “Testofin.”
If that sounds complicated, here's the scoop: Testofin is an trademarked name given to an extract from the fenugreek herb. Testofin contains a specific mixture of extracts that have been given the name “Fenusides.”
For more on Testofin see my review of MDrive where I look at some of the research.
Does Prolongz Contain Cordyceps?
Cordyeps is not listed on the Prolongz label however on the “About Page” of Prolongz.com they say:
The heart of the Prolongz™, formula is two very unique extracts derived from Cordyceps (the mushroom) and Fenugreek (the seed).
Cordyceps? As far as I can tell cordyceps is not mentioned anywhere on the Prolongz label. None of the ingredients listed on the label come from cordyceps either. So, where is this coming from?
As far as I can tell Cordyceps plays no role in helping premature ejaculation or making erections last longer. For more on Cordyceps, see my reviews of
- Optygen (endurance supplement)
- M Drive (Low T supplement)
If anyone can tell me if Cordyceps is in Prolongz, please let me know and I'll update my review.
Prolongz Side Effects
I'm not aware of any side effects from taking Prolongz. Looking at the ingredients, here are some theoretical side effects people may want to ask their doctors about
Fenugreek and ginseng may have an anti-blood-clotting effect. That means people who take blood thinner medications, should speak to their doctor before using fenugreek or any product that contains fenugreek.
Fenugreek and ginseng may lower blood sugar levels. While diabetics might think this is a good thing, its possible that this might make blood sugar levels go to low in diabetics who take diabetes medications.
Stop Prolongz –and all other supplements – at least 2 weeks before surgery.
Women should not use fenugreek-containing supplements while pregnant or nursing.
How Much Does Prolongz Cost?
When I looked at the product website, they were running a special offer where they would ship people a 1 month's supply of prolongz for $4.95. People who take advantage of this need to know that doing so puts them into an autoshop program. This means that if they do not cancel within 15 days – of ordering the product, not receiving it – they will be billed the full price of $89.95. After 45 days, people will be sent another 30-day supply of Prolongz and charged $69.95. This will continue each month until the auto-shipment is canceled. Any bottles that are returned to the company have a $10 restocking fee.
Keep in mind that the 15-day trial period starts WHEN YOU ORDER the product. Not when you receive the product. All this information is plainly listed on the product website.
How to Cancel Prolongz
To cancel auto-shipments of Prolongz, call this number which is listed on Prolongz.com 877-404-4686. The corporate office phone # is 909- 451-0753.
Those who wish to email the company can do so with this address: firstname.lastname@example.org and those who wish to write a letter can do so by mailing this address: Prolongz 1420 N. Claremont Blvd #111A
Claremont, CA 91711.
Does Prolongz Work?
I didn't try Prolongz so I have no idea if it works or not. I can only give my opinion which is I don't see any clinical trials on the product itself. Of course lack of evidence doesn't mean something won't work. It just means for me, I'd like to see clinical trials. If it worked for you, I'm happy and I hope you share your thoughts below so others can see. If clinical trials on Prolongz are published, I will be more than happy to update my review with those results.
Dr. mario Fridland says
I’m interesting about Prolongz studies
Dr. mario Fridland says
I’m a sexology and cannot find one treatment that realy can satisfice my patients.
why there are not any study serious about the results and complication ? if there are I bake to send me the direction
Hi Dr Fridland, other than what I posted in this review, I’m not aware of anything new on Prolongz supplements. For what its worth I think the active ingredient in Prolongz might be fenugreek. I have seen some research studies on that. Here’s what I see on Pubmed
If you have any other questions, just let me know and I’ll try to help.
GNC now offers this product. I purchased some thru GNC and will update with results. I ordered 2 months worth so it’ll have time to perhaps work.
Byll, thanks for letting me know about GNC and Prolongz. I will look forward to learning how your 2 month trial goes.
Passed Off says
Do Not Waste Your Money!!!!!
IF YOU DO NOT RETURN THE 15 DAY TRIAL, WITHIN 15 DAYS, THEY WILL CHARGE YOU AGAIN FOR ($89.95) WHICH THEY SAY IS FULL AMOUNT, BUT THE NEXT MONTH THEY ONLY CHARGED ME ($69.95) FOR A MONTH. LOOKS LIKE THEY BULKED UP THE 1ST MONTHS PRICE HUH? THATS ($4.95+$89.95) JUST FOR THE 15 DAY TRIAL. THEY ARE RIPPING PEOPLE OFF!!!!!
Ira Brown says
Did not work for us, I will not reorder the product again knowingly.

Wayne white says
Has anyone tried prolongz and had success with it?
Wayne white says
Has anyone followed the directions for prolongz and still had no success with it?
Personally I don’t give BBB ratings much credence. The most unethical company I’ve ever worked for had an A rating despite out and out lies on their Web site, not delivering on products clients had paid for, and unfair business practices. Your better off seeing what other people have to say. That said it looks like this company accused of making fraudulent claims for years. Here is one of the numerous articles I found.
Mark, thanks for the link. I list the BBB ratings because they can provide additional information which some might find useful. BBB ratings do change from time to time. I noticed the rating is now a “B” on the company.
i flound that u can order this product with out the auto ship by just googling the product for $36.79 i month supply plain n simple
Flavor, thanks for the heads up. Just an FYI for you, your website was tossing up a 404 code when I clicked it so I took it out of your comment.
what is a 404 code, please?
Leon, It means a link doesn’t go to where to where its supposed to go to? I checked every link in my review. They all work. If you can tell me the link that had the 404 error, I can try to fix it.
