i agree that it is totally ridiculous that an OTC prohormone (and yes this is a prohormone since it does have androstendione as a base molecule attached to it) would increase test levels up to 10000%. I mean is it even possible to accurately measure a value that calculates to 10,000 %? But, this stuff does make you very focused and aggressive. In layman's terms, this stuff will make you feel JACKED. In three days, my weight already went up a pound without increasing my calories. So far, my workout since starting this stuff was awesome. I was able to do stiff legged deadlifts for reps (about 10) with 300 lbs. with strict form. And by the end of the workout, my need to lift more was still there. I know for some of you that it is hard to believe that GNC can actually sell a product that is actually worth a crap. Believe me, my mentality with regard to supplements and ergogenic aids has always been more focused on synthetics rather "naturally occurring substances". Reason? cause they work. If natural test boosters and ergogenic aids actually produced these above normal superhuman results as advertised in the magazines, then everyone of us normal people would be looking like Melvin Anthony, Dennis Wolf, or Victor Martinez. And also I think alot of you out there have been screwed by some idiot wearing a red shirt with the logo "GNC" who told you that supplement x with tribulus really works cause his buddy increased his bench by 30 lbs. by using it. GNC has produced a stigma of selling hyped up products that produced very little results. Overpriced and underdosed or worthless ingredients that produced next to nothing as far as muscle building is concerned. BUT, who would have thought that this billion dollar corporation would actually sell just one item out of the hundreds in their stock that actually works. By the way, I do have an unfair advantage. According to the Aug 2008 issue of Muscular Development, asian man (yes, i'm filipino) do not have a gene that detects the presence of exogenous test metabolites in the urine. Meaning, asian men are hypersensitive to test in comparison to caucasians and other nationalites. Go figure. Anyway, if your asian, buy it and get really freakin big and strong.
