Im 23 years old been lifting for 2 years. Im 5'9" only 155 right now becuase I took 2 1/2 months off of lifting so lost my gains. But however I've decided that Im going to try some type of injection for the first time. What is the best choice for me? I want something with a decent gain with very little side affects. I eat 3500 cals a day just started doing that.
