I had the initial injection site pain in the thighs and butt. But I’m noticing a lot of pain/soreness in various other muscles IE neck, shoulder, biceps seem to be the most prominent. My lifts haven’t gone up drastically from where I was prior to running gear. I’m 6 weeks in on 600mg/wk of TC 200. New supplier, wondering if bad batch, poor quality, etc can cause excessive muscle pain. I will start tracking pain level of each day and see if it correlates with injection timing. Anyone else experience this?
