I've been running gear since about 2015. I have never had any issues.
About a year ago I switched labs because the one I was using prior got shut down. At first it was great felt good looked good and strength was great. I came off cycle and got back on the way I was suppose to.
Now for the past month every pin I take the next day is swollen and sore. No redness no heat, just swollen and sore. It doesn't matter where I go, quad, glute, chest, delt it never fails. Would my body start reacting to the gear differently over time or would it be more gear related
