One of the responses to my last post (winnie-oil VS orals) brought up something that I've been curious about. Why is it that some gear seems to cause pain in the injection site's muscle? There doesn't seem to be a rhyme or reason that I have noticed. I've seen soreness vary from slight to almost excruciating, in numerous muscle groups, & from a variety of oils. Any one know? Thanks guys!
