5-Amino-1MQ
Summary
P21 is a synthetic peptide derived from CNTF (ciliary neurotrophic factor) that promotes hippocampal neurogenesis, enhances memory and spatial learning, and may reduce amyloid-beta pathology. It is used as a neurogenic and cognitive enhancer with potential anti-Alzheimer's applications.
5-Amino-1MQ is a small-molecule NNMT (Nicotinamide N-methyltransferase) inhibitor that raises intracellular NAD+ levels and promotes fat burning. It is notable for targeting adipose tissue directly, reducing fat cell size and number while increasing metabolic rate.
