echoing the statements from above, test above 250mg/ml is never a pleasurable experience... The only way to ease the pain is to inject no more than 1/2cc at a time and needs to be cut with something else, 1/2 - 1cc of deca is good... Also break up the injections, too much volume = pip/discomfort as well
bottom line is your gear is gonna hurt...
