So my pharma grade test c that I've been using for the last 2 and a half years has been great. I stopped taking anything back around the first of summer just to see...
In doing that, I built up a stock pile of test, so after a few months off I went back on it. So the vials I'm now using are about 6 months old. I get 10 1ml vials that are 200mg per. Anyway, I'm on like the 7th vial of the batch that's about 6 months old, and i noticed a few weeks ago, that after injection, my quad feels like its been hit. Like someone gave me a charlie horse. It gets sore a day or two after injection, and stays sore for about 5 days. Feels like a bit of a knot there at the injection site, and it stays warm around that area, but doesn't seen to have any infection.
Wondering if my test is old? I take 100mg per week, so I get two doses per vial. I heated the second dose up in hot water and that seems to help.
