Melanotan 2 is a synthetic peptide that stimulates the production of melanin, providing a natural tan without the need for extended sun exposure. It binds to melanocortin receptors in the skin, enhancing the body's natural ability to tan and offering protection against UV radiation. Beyond tanning, Melanotan 2 is known for its potential to increase libido, improve sexual function, and positively impact mood. It can also help with fat loss by increasing lipolysis and may improve skin health through its ability to boost collagen production. This makes it a versatile peptide for both aesthetic and health benefits.
