Hey ive just started a sust 250 cycle and I first pinned monday in my side delt I still have a slight pain there but i guess thats because it was my first ever pin. I then pinned again today in my rear delt, but this one is quite sore its not red or inflamed but the first site never rele got sore untill the day after and this one is the same day. Should I be worried or am I over thinking lol
