Melanotan II- Summary
- AICAR is a cell-permeable AMP analog that activates AMPK (AMP-activated protein kinase) — the master metabolic switch that triggers fat burning, mitochondrial biogenesis, and adaptations normally only achieved through exercise. It has been called the 'exercise in a pill' compound.
- Melanotan II is a synthetic analog of alpha-melanocyte-stimulating hormone (α-MSH) that stimulates melanin production (skin tanning), suppresses appetite, and enhances sexual function. It is not FDA-approved and has significant safety concerns including mole changes and cardiovascular effects.
