Is it possible I’m allergic to Mots-C?

I’ve been taking mots-C with no reactions under than redness at the injection site that goes away within an hour. But I just switched vendors and after one dose of their mots-C (literally only took 1mg) I’m having weird reactions. I already have been getting histamine reactions from GHK and my eyelids are super red and my face is itchy… then taking this mots-C dose it seems like everything intensified .. what the heck 😭
