i injected into both my deltroids for the first time 3 days ago. the jabs were absolutely painless but now my left delt has a red rash running down from the injection site onto my bicep. the soreness is not as bad now but feels a little warm. is this signs of an infection? i always make sure everything is 100% sterile using alcohol wipes etc. the gear i'm using is tri tren 150 at 1ml per jab and cypionate at 1.5ml per jab.
