Isatest may be my new fave Testbooster

Overall: 9 | Effectiveness: 10 | Value: 7

Perhaps even at my age I am just a great responder to certain products such as Test Boosters and Creatine. Don't get it twisted, I know this isn't creatine, im just saying regardless of a blend or straight mono, I notice the effects in it very well. The same can be said for the few T-boosters I have...

Great overall health benefits and libido but lighter on the AI than I prefer

Overall: 8 | Effectiveness: 8 | Value: 9

iSatori continues to be a top shelf company and I feel confident in using any product that they put out. In the interest of fairness I must also say that I am a tough customer when it comes to using natty test boosters and as such, mainly use them during PCT. I wasn't disappointed.

True to form, another lengthy, in-depth review... ;-)

I ran a 6-week cycle of Halotest (H-Drol) and used this product as my primary natty test booster for my PCT. I had read amazing reviews on it and knew that iSatori was a solid company who put some effort into developping a superior...

Overall: 8 | Effectiveness: 9 | Value: 7

Hey, this is my first review, I will attempt to be as thorough as possible.

Background/Overview(feel free to skip): Haven't really trained seriously since I was 24(since then would work out 1 maybe 2 a week), decided I wanted to improve my body again and considered using PHs but decided those were...

5 second review goes to iSatori's Isa-Test GF. I ran this T-booster a few months back for 12 weeks straight and I got to say I really enjoyed it. I waited to run a couple other t-boosters before reviewing this product as this was my first one and had nothing to compare it against.

I literally...

My first review…

After reading the good reviews about this product I decided to go ahead and try it out as a standalone. This was my first testosterone booster. I ran two bottles back to back to experience the full effect. WOW! This really is a good product and I will continue to buy it and...

cookken's Isa-Test GF Review

Overall: 9 | Effectiveness: 9 | Value: 6

To start, I have just finished up two bottles of this stuff and I have to say I am rather pleased. This is the first natural test booster I have used that truly works. Now, it is not as powerful as a PH, but it definitely raised my testosterone levels.

First a bit of background on dosing. The...

Absolutely awesome

Overall: 10 | Effectiveness: 10 | Value: 9

I am about a week off of a four week run on this stuff. Absolutely awesome. I didn't experience any sides during or since. The only side I guess I could claim is sore knees, but I talked to a medic and he told me it's most likely due to the increase in weight. That, and I have always had bad knees,...

Overall: 10 | Effectiveness: 10 | Value: 9

Let me start off by saying this is my first review. I just got done with two bottles that lasted me 8 weeks. I took it as followed, 4 pills 1 hour prior to workout and on non training days, 4 before bed. Let me get by saying that I didnt notice anything until the first week, and I didnt expect to...
