It depends. Obviously you have to have a good diet. In the case of a steroid like primobolan it's all about nitrogen retention. Guys use TWICE as much as they need because they don't take in the fuel that the steroid uses -- PROTEIN.
GEAR is like protein X's TEN. If you get 200 grams a day from food an shakes and use 20 tabs a day, that's like getting 400 grams of protein a day. Do you realize how advantageous that is over the course of a couple of months?
Now people complain, Oh, that's so much. A bottle won't last long. Well, you can use GEAR just as a reinforcement and insurance. 10 caps a day can assure you always have enough aminos in you. That'll help. But honestly, if you want to see a dramatic change -- 20 caps for two months. Fuck, even steroids takes a decent amount and that much time to see a difference.
