DIY Nabota Beginner

Hey guys, first time doing DIY Nabota (100u) for TMJD/Masseters. I’m seeing a lot of conflicting info and could use some clarity:

1. How many mL is best for a 100u vial? (Is 2.5mL the standard?)

2. I have 100-unit insulin syringes. If I use 2.5mL of saline, how many "ticks" on the syringe equal 1 unit of tox?

3. What gauge/length is best for the face vs. the deep masseter muscle?

4. My jaw is uneven. Do you inject more units into the larger side, or keep it equal? How many units per side do you recommend starting with?

5. Is masseter always a 90-degree "straight in" injection?

6. Who are the best creators or threads to watch for mapping/depth tutorials?

Thanks for any tips!

(P.s. English isn’t my first language so I used chatgpt to help me organize my thoughts, thanks for understanding!)
