I just stopped using 750 mgs of test-e and 400 mgs of deca,which I was injecting into my quads without any pain.I just took my first shot of 75mgs of tren-a and 100mgs of test prop which I also injected into my quad. the pain is terrible i can hardly walk there is a little bit of swelling.This my 4th cycle never had pain like this has anyone had this happen?or can anyone tell me we why it might be happening?
