Bros--
Just trying to get an opinion.. have been reading some posts, and I'm trying to find the best place to inject. I have both (22 gauge 1 1/2 pin, and 23 gauge 1 inch pin) Which is best to use to insure a deep injestion? Does size matter? he he I usually inject in the quads because I like the control factor. Have been thinking of rotating to the delts and back to quads. Any thoughts please :scratch:
