It was Test E dosed at 400mg/ml and contains 3%BA. He always wipes the top of the vial and wipes the injection area down 2 times. He used an 25g needle to inject one half cc (200mg) into his left delt. Injection went smooth. He didn't feel any pain at all until the next day. The day after the injection his delt hurt really bad and had swollen. He explained the pain to be like an really extreme PiP. It has now gone 2 more days and his pain is still the same and swelling hasn't gone up or down. The pain hasn't spread to other areas, he only feels discomfort when touching the medial deltoid, where he injected.
