hey i had read somewhere that some underground labs tend to leave out benzyl benzoate in there gear, which really makes short esters hurt for days after injection. i get my gear from an underground lab and had bought masteron a couplr of months back and had to stop from the pain.
considering i had to inject every other day eventually my whole body was killing me. i have heard you can add it in yourself, anyone happen to know how and/or how much to add? thanks for any help guys
