Small amounts that milos suggested got me maybe 15 pounds ,using close to 4 to 5 grams a week got me crazy big and unhealthy.Not advocating steroid abuse but i did see the results.
Am a healthy natural now for 2 years with athletic physique so why bother using the shit.
Have talked to a few friends who are aspiring bodybuilders and the take more or less what GH15 professes there quite honest with me knowing my background and one is Pro size they just live,work,sleep,train,inject,swallow pills and live what i see as determined Bodybuilding life 24/7.
And by the way The three amigos is what i call them all squat 600 pounds
