for the past two shot in my quads (others are in the glutes) i've been stickin when all of a sudden my quad starts to spasm, i immediatelt pulled back out, ive done this before on othe cycles and had no such dillema, but man this has ****in freaked me out, can't stop thinking about it, i think ive lost my bottle to stick myself in that area, really don't want the next jab to come around, i know i sound like a right woman moaning but i hate that ****! do you think it was a vein that i hit?
