Qv enanthate will hurt if you get a 50ml jug. the BA is high as hell. My first few shots I could barely walk without poppin pills all day. My source was doing the same shit, but in a 10ml vial, no pain at all.
Soooooo, I learned that after heating up the oil before each shot, injecting slow as hell, and a massage of the sitre afterwards for a few minutes, and all was good.
QV is a great deal (short of making Anabolic Androgenic Steroids (AAS) yourself). I got 35lbs solid off of it in the last eight months. Good sheat if you ask me!!
