last week after i injected into my leg quad i had incredible pain like ive never felt before and i was on week 6 of my cycle..the whole week my leg hurt so freaking bad..now its better but i was tryin to figure out what was wrong with it..i just started training again in muay tai and my first workout was killer on my legs...the next day i injected in my leg...could that be the reason because if it is i dont wanna inject there anymore because it messed up my whole training and i could go back for another week
