Ok I have been on Test Cyp for 8 weeks than switched to Test Prop for my last 7weeks before my Show. I was using 10ml vial for 1st 10 injects eod no
pain at all always shoot in my quads than switched to amps due to this is how I obtained it. I was told there is no problem with either and both are legit. Problem is the pain I experienced was unlike any other type I ever had I was limping for three days no matter what quad I shot it in. Anyway got hold of another vial of same Prop and I had no pain at all with this mix . Any help
on this could one be more potent than another ?
