Description
This enrolled 390 people with type 2 diabetes, all on insulin, and randomised them to metformin 850 mg three times daily or placebo, with a follow-up of just over 4 years (de Jager et al, 2010)

High doses of Vitamin C taken within 1 hour of the shot may lower B12 in blood (minor, stagger doses)

PMID: 22074294

Noat least not in the way semaglutide/tirzepatide do

Since your body does not make it, you have to get B12 from food or supplements
