5-Amino-1MQ is a small molecule inhibitor of nicotinamide N-methyltransferase (NNMT), an enzyme that catalyzes the transfer of a methyl group from S-adenosylmethionine (SAM) to nicotinamide, generating 1-methylnicotinamide (1-MNA). By inhibiting NNMT, 5-Amino-1MQ increases intracellular NAD+ levels, reduces 1-MNA production, suppresses lipogenesis in adipocytes, and modulates the methionine-homocysteine cycle. In vivo, it significantly reduces body weight, white adipose mass, and adipocyte size through enhanced energy expenditure and altered lipid metabolism.
Research indicates 50-150 mg daily via oral administration, typically divided into 1-2 doses.
Morning dosing preferred. Can be taken with or without food.
8-12 week cycles.
P21 is a tetrapeptide (DGGL — Asp-Gly-Gly-Leu) derived from the most active region of ciliary neurotrophic factor (CNTF, residues 148-151), identified through reverse engineering of Cerebrolysin. An adamantylated glycine enhances BBB permeability and metabolic stability. P21 works through LIF/STAT3 pathway inhibition, BDNF/TrkB/CREB signaling enhancement, and restoration of synaptic proteins (synaptophysin, synapsin I) and glutamate receptors. It promotes neurogenesis and maturation of newborn neurons in the dentate gyrus.
Research indicates 750 mcg-1 mg daily via intranasal administration or subcutaneous injection.
Morning dosing preferred for cognitive effects.
4-8 week cycles with 4-week rest periods.
