if you shoot staright trenbolone ace ed you will get NO PAIN AT ALL even the following day.....nothing.....no scar tissue build up either...use a 25 g 1" pin and shoot it everywhere.....if its mixed with testosterone propionate it will get sore quick with ed or eod shots.....stick with trenbolone ace ed and mix your testosterone propionate with sterile oil and shoot eod in the quds and glutes only....stick trenbolone in the delts, pecs , calfs, lats etc....1/2cc of painless gear ed is nothing at all
