Research Overview
Gamma-MSH
Gamma-MSH has been investigated as part of the broader melanocortin network that regulates pigmentation. Evidence suggests it can contribute to melanocyte signaling, though its cosmetic use remains experimental.
ACTH
ACTH activates melanocortin receptors on melanocytes and can increase pigment synthesis. It is widely used as a reference peptide in studies of tanning, adrenal biology, and hyperpigmentation.
