I have been using Jack3D and LOVE it! But just wanted to try something different so I switched to the Muscle Tech naNO Vapor and was very disapointed, it didnt have near the pump and focusing abilities that Jack3D did and the worse part was it upset my stomach very badly, so bad I had to leave the gym to go home and throw up.
Has anyone else had these side effects from vapor?






thanks for wrecking the dream man!!! lmao ;P
