Scientists often examine the peptide in laboratory models that look at endothelial cell behavior, fibroblast movement, and nitric-oxide related pathways
But the slowed gastric transit affects the absorption of multiple nutrients, and B12 is particularly vulnerable

Research examines its effects on NNMT activity, NAD+ homeostasis, metabolic pathway utilization, energy expenditure, and adipose-tissue endpoints independent of feeding-behavior changes
While these researchers' work appears rigorous from a technical standpoint, the lack of independent replication from other laboratories globally is a significant concern in scientific research
