I used this product during 1 month. And I checked testosterone level in my blood before and after. It increased by 50%.

ISA-Test GF Does Work

Posted by iHerb Customer on Feb 03, 2012 | Verified Purchase

I'm regaining my sex life at 60 thanks to this product. Takes awhile but by the second bottle you will notice the results. Make sure you take 4 capsules a day like they say.

Thanks for your feedback!

This stuff works great. Increased stamina, and aggression, and sex drive. Even cause some acne, which I haven't has since I was a teen. I cycle 2 months on, 1 month off.

The one I have been looking for!

This product really seemed to make a difference in my energy levels and health. My wife definitely noticed a difference. Will continue to take this product and would recommend it to anyone looking to get that spark back and feel younger.

Thanks for your feedback!

Strong like bull

Love this product. At first I was hesitant to try ISA-Test, but I'm glad I did. Started on a low dose (1 pill). During sluggish days I find it easier to go over stairs and hills for my walks. Plus my energy levels noticeably improve. I wouldn't say it turns me in to the hulk, but definitely has added muscle and cut fat.

Thanks for your feedback!

Amazing product!

They seem to have changed the formula. Testofen is no longer listed as the 1st ingredient (I assume it now contains less Testofen).

Thanks for your feedback!

Isatori review

Posted by iHerb Customer on Nov 14, 2013 | Verified Purchase

Only been taking for a while, so not sure yet. Keeps the nether regions ready for action. Still, just started taking a few weeks ago, so just a 3 star rating at this point.

Thanks for your feedback!
