Hmmmmmmmm,22 yrs old @150 lbs and already using gear.It seems to me you would be fine with creatine and a dramatic improvement in your diet.I lift with a guy your size and he is tiny,I cant imagine him using gear until he learns how to eat properly.
I dont get the really young,bean pole skinny guys wanting to use gear.I was 6'3" 150 when I was 18 and I was 225 at 23 after learning how to eat.My glutes were virgin till I was 40 yrs old and my natural levels dropped.
It's really obvious you dont have a clue with your previous adventure so why not just eat better and lift for 5 more yrs or until you're 185+ lbs,the weight and strength will come young man.Skip the needle for now........
