By dosage, the mean changes were: 500 mcg: 127% 750 mcg: 176% (single study) 1,000 mcg: 280% 1,500 mcg: 310% 2000 mcg: 260% 5,000 mcg: 62% While 1,500 mcg of vitamin B12 showed the highest average increase, the effect plateaued or declined at higher doses, suggesting a possible saturation of absorption pathways
MOTS-c has a short half-life (46 hours), so missing a single dose doesn't create long-term metabolic disruption, but it does interrupt the AMPK activation pattern for that 48-hour window
Intrinsic Factor and Absorption Challenges As previously noted, intrinsic factor is a key player in B12 absorption, as it binds to the vitamin, allowing for proper absorption
Adipose identity: NNMT appears involved in adipocyte development, not merely a marker
Research-grade purity: Fit for educational and research use that demands high-quality peptides
The optimal pH range for AHK-Cu formulations falls between 5 and 7
