i wish i bought more than one bottle, i was worried about hairloss. This stuff didnt do much for me until i hit 70mg and up. I take it all preworkout, some 1hr pre, some 30min pre. The strength gain is shocking once you start working out. I havent noticed increase in acne or hairloss, if anything it has made both of them better, hair is growing faster and acne has been clear of late. I wonder if you could use this for a whole injectable cycle as a preworkout only. Doesnt seem that harsh on the body. The reason i dose all of it preworkout is because i heard the half life is like 2 hours or so..
