I have been injecting 300 mg of tt deca every week for 6 weeks into my quads. the first 5 weeks were great the needle went right in no pain. Now today i put the needle to my skin and that shit hurt like a bitch and when i pushed it through it hurt even more. It was by far the most painful injection yet. My question is does anyone have any idea why the first 5 injections were painless and this one hurt so much? I did not change anything, i used the same size needle, 23g by the way.
