400mg/wk will do for you bro. Ganabol is 50mg/ml so 8ml is needed to get to 400mg, but the stuff is great. BTW whats your cycle going to look like? are you just doing EQ? toss in some Test and if your not doing dbols put in some Winny towards the end of your cycle. with Bf at 20 you wanna harden up, well I would. You can try ECA and clen cycle after you Cycle to cut up and that would work great.
