Had my first jab of my cycle on thursday (1ml of 300mg/ml CLP sustanon into the glute). Ever since Friday I've had really nasty swelling and pain around the injection site, despite warming and massaging the area immediately after the jab. It's not getting any better- if anything it's getting worse.
Should I be worried or is this usual when opening up a new site? My last cycle was slightly less concentrated sust, and i had no problems whatsoever. The area is slightly red too. Cheers for any advice, Rich.
