I am running Sust 250 EOD. At first I was just pinning my delts but it was too much so I began delts and biceps. I usually experience a knot in the injection site for up to 4 days after the injection which is tender and painful. I could do legs/glutes but I have to walk upwards of 5-7 miles a day (I am in Iraq) and don’t feel like limping around. My question is if it is okay to pin a muscle once a week or is that bad? Thanks.
