This is the second thread you've made on follistatin - you're wasting your time with it. If there was a product out there that worked we'd have a lot more jacked guys walking around. I think myostatin is one of those things we're very unlikely to ever crack the code on.
I think we will crack the code personally. Will we able to do it at a cost that people can actually afford it another question. If you look in this thread I made some posts in regards to myostatin antibodies/blockers. But buying a couple bottles of follistatin 344 to try and inhibit myostatin effectively is a total waste of time. I honestly think this technology is about 5-10 years away from a practical application. If you look at the dosages.they are using on a mg/kg basis you really need A LOT like couple hundred grand worth. That's if you can even find it and it's real.
I think the young bodybuilders who gets into chemistry, genetics and bio engineering will get a leg up on everyone else in this regard. Anyway check out my posts in this thread if your interested. I stayed up all night the other day looking into the latest and greatest in myostatin currently
