No PIP here, it could be the carrier oil for you. Personally I cannot pin Tren A unless it's in an MCT base, ahit burns like fire in my delts and biceps, even traps. Last time I had spoken with S he expressed that there would be a choice in carrier oil in the future for nearly every compound, a change from GSO to MCT or vice versa may be just what the Dr ordered. I'm fortunate enough to still have a couple of the SP special 20ml bottles of Primo he released contest time a while back, GSO and smooth for me. But, everyone is different as I expressed regarding Tren A. Not exactly an exact science since everybody has their own reactions to compounds, just reiterating that if it's from SP, you have nothing to worry about, this man is fastidious when it comes to purity and quality.
