well a week ago i injected into my glutes and they started to swell up.. there wasnt any pain or anyhting else ... they just were swollen from the injection... and i didnt inject in the glutes for a week or more i gave em a break and substituted my pecs instead... i just shot my left glute today and it swole up again and got a bruise mark.. kinda dark... something i shud be worried about? this is my first injectable cycle..and ive shot 1 ml of tren... homemade
