For every 10 injections I do, 6 of them will bleed like crazy! Doesn't matter where, glute, thigh, delt... about 4 out of 10 will go in nicely and leave no bruising or blood. The other 6 hurt the second I stick them in (which tells me this one is going to be a bleeder!) Not a big issue, just pisses me off. Needed to vent, thanks for listening!
