I am having a real bad problem with bruising and extreme soreness after doing my HGH injections. First of all my HGH is legit and that surely is not the problem. Here is what I am doing

3-4iu daily (in morning)
I keep Vials in the Fridge and take out before injection and let them warm up just a little.

I have been taking and giving shots for 8 years. Never had bruising issues or soreness.

I am using a 31g 1/2 slin and started out doing Subq, but started bruising for some reason? Then did some IM shots, no bruising there but soreness for about a day?

WTF guys, I have never had this problem before. Can someone give me some advice, I am new to the subq shots, but have done tons of research and believe to be doing it correctly. So not sure what I am doing wrong to be getting bruised and sore....

Thanks.
