to those of you who dont think it can happen to you. today, in my second week of injections (third so far overall), i hit a vein in the upper outer part of right glute. yup, the blood came dripping in the syringe, and wow was i shocked. switched pins, and i went to my quad out of fear of poking in the glute again.
just a reminder to always aspirate. even in the glutes, where its a bitch to do so. everyone wants the muscle, but dont risk your life over it.
