So I have been pinning my pecs (for the first time) for the last 4 months. 1ml each pec once per week. Have been using 29g slin pins backloaded. In the last few weeks I've been getting sore lumps in the muscle at the injection site, they last 3-5 days before going away. The are probably the size of a bottle top.
Am I doing something wrong?
