I'll try to make this short as possible. Started this game around 2001 with 18 gauge 1 1/2 inch. Over time it felt like heaven getting to 25 gauge 1 inch. I see a lot of guys nowadays using much smaller sizes and claiming everything is good to go. School me please. What size needles are now reasonable to use for IM injections? I'm about to switch back to an EOD scheme and I'm curious as to how small I can go. I don't mind continuing 25g for IM but my 31g for hgh sub Q is awesome. What are pros/cons for going smaller and what kind of experience/protocols is the rest of this board using? Example: how small gauge size can I reasonably go for common areas? (glutes, delts, quads) Thanks in advance anyone who takes the time to answer some older guy's questions!
