@buffbro1 from that powerpoint I shared its quite a tecnical injection, not the usual subq that we’re used to. Starting at 2:08 see how he injects while slowly withdrawing?
If it was me (and I’m looking into this for myself tbh) I’d stick with the type of needle and gage recommended, less chance of fucking it up. Those needles are expensive though and I have a feeling they’re standard needles with a fancy name and packaging. I’ve seen 25g 70-100mm being used in most videos/presentations.
Edit: Fuck I’ve just realized its a 10cm needle, going in at 30-45 degrees. Is this for really fat people you have to wonder as there’s no way a 10cm needle isnt piercing through my abs no matter how slanted it is when its goes in
Edit2: This video is super informative, its in Spanish but it guides you through the process step by step.
