ive used nolotili for every show ive been in.... knocks some people sick so try it out as has been said, gets the small muscle groups like little rocks tho, lasts around 24 hrs,,, so you can either put them in late at night before, or early on the morning of the show,,, i prefer to use slin pins, you can get the longer needle length as they work better
best in bi's, tris, side and rear delts.... you can do calves, but i think it would knack, and youd feel cramped all day
when you put it in, dab it around the muscle belly, dont just whack it all in one spot, try and enhance your natural shape
