i heard some use B12 to cut your gear? i get bad PIP, not sure if its because of poor jabbing technique or not, i didnt use to get this type of PIP, and im still using the same bottle of test..
but i heard that cutting it with some oil might help?
are these oils or even b12 something you can get online?
btw, this is for test E , as i;ve heard Ethyl Oleate oil is good for shorter esters?
