i have taken npp before and not a single pip from any of the injections. i've also taken mass stack and it gave me no problems at .5ml (along with npp). but when i took it alone at 1ml. i was getting pain near the injection site but not at the injection site. i've been reading some about this and most people using test e and test prop seem to be getting pip. worse so on test prop. I was thinking of doing test prop for my next cycle but if it's going to be as bad as what i've read, then i don't know. is there something in the test that generates the injection area pain?
