I understand about the infection part, I just got worried by the lump, first time issues. Am using 24G 1.5" needle. Thing is, where the lump happened, I had injected 2CCs. So maybe thats too much quantity for a virgin muscle. I inject 1cc at the same time in the other glute as well. So don't know how to rotate with just 2 sites. Am not much confident about the quads or delt injections, so glutes seem safe to me.
