Everyone is going to hit you up with questions like.....for strength, raw size, lean body mass gain, etc. etc.
It is so hard to tell. For me I might have to say Sostenon Redijects. Nothing ever blows me up like that does and I have used evrything but HGH and slin.
On the other hand...I keep more quality mass off Fina. Tren has got to be up there.
