I know this won't be news to some, but I see so many posts about quad PIP (and PIP in general) that I thought this was worth mention. I tried quad injections for the first time while on a blast a couple months ago and got the notorious PIP from hell that everyone talks about. Lasted for days and could barely walk. I did one shot in each quad, got same pip from each leg, then said f that and stuck with delts and glutes the rest of the blast. I was NOT using my trt script gear for the blast btw. Now that I'm off blast and back on my trt (straight from the local pharmacy) I decided to try another quad pin yesterday. 24 hours later....nothing! Not even the slightest hint of pip. Just goes to show how much of a role gear quality/source plays in pip.
