I'm not worried about a sore arm, I am worried anaphylaxis shock.
I am seriously allergic to aspirin and foods chemically similar.... I'm also seriously allergic to sulphur dioxide. which are the 220s preservatives on your canned foods ingredients.
I went into anaphylaxis shock from a drug called Toradol which is chemically related to ibuprofen
I actually went flat line for nearly 4 seconds behind that shit when I was 19
I have a very strong immune system, haven't experienced a fever/flu/cold/etc in over 25 years and aside from being just slightly shorter than flynn's greenly tinted crooked fangs I'm in relatively good shape.
So I'm very hesitant to inject something into my body unless it reads testosterone cypionate on the label and was mass produced under some very questionable quality control standards in a lab somewhere in Somalia.
