Hey everyone, i was lifting hard with my friend the other day whose 5 weeks into his sustanon 250 cycle, and we were both real pumped and i just made a joke to him about his face when he lifts and he slammed me in the face! He said he didnt mean to but he can get pissed really easy. I didnt think violence was an issue with sust like it is fina? Is that a side effect?
