Just injected my for week two of cycle. Last week did upper glute on right side. Yesterday just did left side. First week didn't hurt and went smoothly, but yesterday kind of hurt going in and bled quite a bit afterwards. Also today there is a little black and blue bruise . Is this a problem, or did a vessel or something just get hit. Another thing with that blood coming out does the gear also come out as the blood does, or is it deeper and stays in the muscle. Just wondering? Thanks for the info
