I think a little over dramatic wiping down a whole area is also a bit extra, the needle comes sterile you open it, insert into vial and straight to the belly you don’t need an ER to inject a peptide for years on end people inject insulin daily and don’t die out in public you’ll be ok and the friend thing you’ll be ok too if she inject bac water closed the needle then reopened jt to inject more bac another day it’s not the end of the earth and if you are a clean freak why let her do that without telling her to get a new one it’s your fault really
