pharm grade primo bayer.. i tried every trick in the book.. nothing helped. i was in agony after each injection, on the ground in pain like someone had hit me with a baseball bat and it took 3 days for the pain to ease off... this isn't gonna fly because it will hurt your sleep and worse hurt your workouts having to navigate around muscle pain.
i tried this UG primo from red dragon and there is zero PIP.. none whatsoever. so its all about whats in it.
i would just deal with it since you already have the stuff, but in the future always buy as less as possible and try it out first to see if there is PIP and if you like then buy more. don't sell the stuff, now you are opening yourself up to a serious offense. its one thing to use, they don't care about gym rats who want to put on muscle.. its another thing to sell .. dude at my old gym got 13 years in fed prison for dealing after he turned down the plea bargain.. left behind 3 kids and a wife.
inject 1CC at a time. mix it with other stuff. heat up the oil before injecting.. this will help .. it won't cure the PIP 100% but it will help
