Been pinning 2.4 cc of test p, sust, tren mix eod. Last 2 injections, besides the terrible pip, there have been debilitating big lumps. The first one was big and red but when away after a few days. I really thought it was an infection at first. The 2nd injection, 24 hours ago, is vey big and painful, and seems to have moved higher than injection site, pushing against my lower back. It hurts to sit and walk, more pain in lower back than butt.
Any opinions?
