So man does this hurt! I've done 3 injections of of Tren/TestP on this cycle. The injection site hurts like all hell. I've read that most people have this issue. I've read in several threads that it helps to cut it with either a sterile oil or B12. What I am unable to find is info on where to buy these items (hopefully OTC) and how to cut it. Do you just load up the syringe with all 3....and whats the ratio? Any advice would be greatly appreciated.
