I've been injecting in quads and been having pip for about 3-4 days after each pin. The pain isn't that bad but its enough to make me walk with a limp for a few days. Been thinking about pinning in ventro glute but not sure exactly where it's at. Googled and saw some charts and videos but just wanted some opinions before I try it. Also I've been pinning quads with 25g 1inch needle, will this be long enough or do I need 1.5.
