My personal opinion is either not heating the oil, or not going deep enough.. only time I've had a big issue with his test is when I tried to pin it in my chest. Heat up a half inch of water in a coffee cup... set in ur vial foe a minute or 2 and then pin with a 1 inch pin minimum and u should be ok... just my opinion tho... most of my local guys are using the same test e that people are complaining about with no issues
This is usually the issue. There are few pain sensing nerve endings in muscle tissue compared to the many in the dermis. Actually, the majority of nerve endings in muscle tissue surround the tendons. Long story short, if the injection isn’t deep enough it’ll leak into the dermis, right where the nerve endings lie. This is the main cause of pip but it can also be caused by high concentration gear concoctions, high BA/BB, or carrier oils within the muscle tissue itself...it’s just much less common than leakage into the dermis.
