the only pip I ever had from MTS products was due to virgin muscles especially my quads. Not saying I'm an experienced user but now I get no pip I literally wake up with no pain/soreness/bumps/lumps etc at all. After I pin I always have a hot bath I find it helps but that just maybe all in my head.

I also take my time during the process I don't rush! and I make sure everything is done step by step no matter what
