Definitely fills me out...feel very pumped when taking it (although I feel pumped from alot of the stuff in my body). It gives very good noticeable gains...I like running drol. Gives a good amount of water rentension and pretty bad back pumps (taurine can help remedy this). I would not recommend taking this at 150mg/day if you have no experiences with orals...this is a very harsh substance. Oh and I mainly blame tren for the hair loss, when I started upping the doses when I was younger my hairline started to recede (although it could be somewhat genetic). So I just shave it off now.
