it seems like it takes me a lot longer to do glutes then quads.
i am shooting 2.5ccs with each stick.
I always cramp up or get so tired from shooting Glutes, its a workout in its self. and when i do my quad i can feel the muscle except or not want the fluid, with the glute i just push to get it done. also my glutes bleed more from the stick.
i dont know where im going with this im just sharing my experience.
