Hey guys today is the beginning of week 4 on my test e 500mg/week cycle. So far iv had a crazy libido increase and a little bit of acne. Today I hit delts and I was getting the most insane pumps iv ever felt before and after a set id put the weights down and my shoulders just felt like they were tearing/going to pop out of my skin. Could this be a sign my test is starting to kick in now?
