Have always prided myself on not experiencing PIP, no matter what I injected. So got a number of vials of DHB, and was injecting M/W/F. I always inject in the glutes, and just go back and forth. By the end of the first week, I had difficulty walking without a noticeable limp. Each day the pain just got worse. My guess is that the compound had crashed in depot, and must have looked under a microscope like a ball of broken glass in my ass! LOL. Was the most miserable thing ever. When I went back to my guy and asked about it, he said I wasn't the only complaint, that he thinks it was DHB base. He told me to throw out the vials, and he'd give me a credit. First time I ever threw gear away, but I wouldn't wish that on anyone! LOL
