So I get up this morning and eat then I goto pin and I had to do it four times.... I never have a prob pinning so this is odd. The first three times I try I get about half way in with a 23g 1" and it feels like I hit something or bottom out. I switch pins and ended up being all set could what I feel like I'm hitting be scar tissue??? I pin eod 150mg test prop I rotate quads cause I tried delts and glute and like quads better. Also started a new bottle of prop today it was from a new batch my source got and it was harder to push in is that normal???
