It sounds like maybe you have never gone through a cycle of injectables, if you have that's my bad. However, as you get through the first week of injections or so, you learn to do it to hurt the least, and realize is not that big of a deal, as for painful AAS, such as prop or sustanon, my friend, just do it slow and go as deep as possible, it should be okay, every once in a while, you will do it and it will hurt for a few days but that's the nature of the beast, I mean, who am I to tell you not to put xylocaine on the injection site, but I have to agree with DiamondCutCows, it seems a bit dramatic to me.
