I have been on test cyp for a month now. My boss was spotted me my first 3 weeks (which was just 1ml 300mg once a week). Until I got my own which was 2 separate orders. One was dragon pharma and the other hutech labs. They came on the exact same day. My cousin is about to be here and I'll take a pic of his shoulder. He is going to pin again in his glute. Im just going to stick with dragon and just see how it affects him this second go round.So first cycle with gear received about a week ago. Yet now you state you pinned 4 other times and no issues? So you've pinned 5 times IM in a week...something isn't adding up.
But your shoulder is probably virgin pin being first time.
