For me it's dark blue tops.I am using QSC primo tested at 220mg pr ml right now, ( I think it's the 'light blue tops' from late 2024, can check when I get home) - No pip for me, but I also inject it combined with a little bit of E,deca and Npp.... So there is that.
Thanks, maybe it's the carrier oil that it causes me the pip.
