Hey guys I'm running dbol/test e/deca I'm in week 4. I trained chest yesterday. About 15 mins into my training my arms became so pumped that it was painful. I'm not complaining at all. I actually loved it. My arms were rock solid. I'm just wondering what would have caused this? My first cycle was test e only I was pumped 24/7 but nothing like yesterday. Any info would be great thanks guys
