dont know if its more tren than sust or not but im injecting 1.5cc of tren and .75cc of sust every other day. well i went into my delt today and it hurt pretty damn bad. im usually good with pain as ive used t400 before without any discomfort. i had one of those Ace heating bandages at home. i put it on there for a couple hours. feels a bit better.. is tren supposed to be painful?
