I used eco prop and it hurt like a mofo for about 3 days, i haven't used it since and it has put me off using prop, I had heard that it was the brand and that other people had this problem, so i got a friend of mine to try it and he said it hurt like a bitch to is this a common trait in prop? I really want to try tren but am to much of a pussy to if its gunna hurt so bad that i cant work or train(it was my first shot in the sholder)
