Lately I've been applying Bi's preworkout (IGF) and occasionally one side will have a "stinging" sensation and the other won't. The side that stings a little always gets a way better pump, along with more soreness. Do you think I'm missing the muscle on the other side? Or any suggestions? Thanks
Oh and on another note....This stuff is awesome as everyone has been saying....Shipping is always great as well.
