I started out running 500mg's of Test E along with my GH. The first week I injected into my front delt I get an abcess. Ever since no matter what area I hit I am in terrible pain and there is swelling for at least 4 days after I even cut down 250mg's and did 125mg's per each glute. The odd thing is I can hit my right glute at 125mg's and there is no pain for the second week in a row. But the delts are still sore as hell and the left glute swells up at 125mg's. My buddies are using the same brand and amount as me and they really have no problems. I have stacked deca along with sust and andropen in the past and have never had any types of problems.
