I have been TRT for 10 years. BEST move I ever made was go to 28 guage insulin syringe. Levels were the same as with the old 22 guage 1". Many many men on excelmale.com use the same needles. Hope that helps.A 1" needle pinning my quads and delts seems excessive to me. I can honestly see nothing good coming out of it. The 1/2" needles I use have worked well for me and I'm curious as to why 1" seems to be the standard. Deeper delivery for faster absorption? More into the blood stream, or deeper into muscle for what exactly? If there is some age old reason other than broscience please let me know and I'll get new needles. Down to about 30 some anyways.
