This is nuts. Almost like an infection, but not as bad. 2 days ago I decided that rather then shooting my B12 separately, I would just shoot it with my peptides (GHRP-2 + Mod GRF (1-29)) Instantly started to get itchy, and swelling a bit.
Now after 48 hours I'm still left with an itchy, inflamed area. And it's got a "bruising" color to it the size of a nickel.
Anyways, this is just a heads up... I wouldn't be mixing your peptides with B12... cuz this sucks bad. lol
