I’m just looking for thoughts and opinions. I’ll give my full history. Using gear for 4-5 years now, I’ve had lumps and pip most of the time. I always use test E as a base. The pip has never been debilitating and the lumps after Injecting and never super obvious or giant but just a little swelling. Never red or hot to the touch either. I tried switching carrier oils and that didn’t really make a difference. I use a 1 inch needs for delts, lats, and glutes. I don’t always shove the whole thing in my lats or delts either. My lats almost never get lumps and don’t get much pip if any at all. It’s mostly delts and glutes. Delt lump usually shows up same day or day after and the pip the same. Glute stuff usually shows up 1-2 days after. They both probably last an average of 2 days of duration. I’ve always put up with it because it’s a small price to pay in the grand scheme of things but any idea why this is?
