I know for oils an inch pin is good for the quad and an 1 1/2 is good for the glute. But are winny injections subject to a different standard? I have heard that because winny is water based u can use slin pins anywhere, glutes and quads? I want to use slin pins for my arms and delts, but I what about the glutes and quads? Also are winny injections more or less painful because of it being water based? Thanks for the read.
