2.2.3 Autophagy and apoptosis Autophagy is an early cellular response to METH-induced stress and is activated by the mTOR signaling pathway (Kongsuphol et al., 2009)
Notably, GLP-1R is abundantly expressed in various brain regions, including the hypothalamus, cortex, and hippocampus, as well as peripheral nervous tissues [10]
The additional GIP activity enhances insulinotropic effects and may amplify weight loss via both central and peripheral pathways not fully replicated by GLP-1 agonism alone 5
Who Might Benefit From B12 Injections
Since its discovery in the periphery, the presence of PPG, GLP-1 and its receptor GLP-1R has also been reported in the central nervous system
User experimentation suggests that longer initial treatment periods (6+ months continuous) support better benefit retention during subsequent breaks, complete discontinuation breaks of 1-2 months show acceptable benefit maintenance for most users, and very extended breaks (3-6+ months) increase risk of regression toward pre-treatment baseline particularly for short initial treatment courses
