I am 6'3, 215. age 20. Been working out for about 4 months. n about another 4 before that on and off. Im pretty slim cuz im tall but feel i have some fat on my stomach and chest. three days ago I started taking a stack of Deca 300 and Test C 400. My friends brother whos an experienced user is saying to mix them and inject about 1mg each. but he hasnt got back to me on how often to do this. its about an 8 week cycle. Suggestions?
