im a week into a prop/dbol cycle...when my enth gets here i plan on switching to enth/dbol. yesterday evening i started experiencing lower back pain. doesnt really feel like muscle soreness. its a deeper kinda pain, like its in my organs. feels kinda like im bloated/constipated but i know its not that...im pretty regular. could it be my kidneys? if so, could it be from the dbol? im taking 50mgdbol/day...25mg in the morn, 25mg evening. one of my bros said it was back pumps, but im not really sure what that is and what causes it.
