I'm new here and new to steroids. I'm 6'3 about 155 lbs. And I'm 5 weeks in my first cycle. Running only test enth at 500 mg/wk. I've trained off and on for 3 years never really gaining weight even with tons off food, protein shakes and weight gainers. My arms and chest seem bigger (noticeable strength gains as well) and I've gained a couple of pounds but is it feasible for me to gain 15lbs from this cycle or is my body type going to limit me?
