I took a shot of enanthate the other day and it didnt hurt going in at all, for the next couple of days it just felt like someone had punched me in the ass cheek, nothing too bad though.
From what I've heard Enanth doesn't hurt, while I've tried sust, and the pain was crazzzzzzy. Good drug, I'm sure, but too painful for me (day post-inject). Gonna use enanth next cycle.
