If your goal is to grow, I like NPP for a real clean, fast acting compound that is still good for mass. I honestly have never used it for a single diet. If I were going to add something to cut, I would pick tren. If your labs are good, thats whats important. It’s such a strong drug, you don't need a lot to get a good result. Some guys do like it while cutting, but I don't know anyone that competes on it.This doesn't mean that tren is risk free at low doses. It sounds like you’re watching your body though. Just keep checking values
