G
GHK-Cu
Copper Peptide ยท GHK Copper
GHK-Cu is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. It declines significantly with age and has been extensively researched for skin remodeling, wound healing, anti-inflammatory effects, and gene expression modulation favoring tissue repair.
GHK
Glycyl-Histidyl-Lysine ยท GHK Tripeptide
GHK (Glycyl-Histidyl-Lysine) is a naturally occurring tripeptide found in human plasma, saliva, and urine. It is the parent molecule of GHK-Cu and Pal-GHK, and has been shown to modulate over 4,000 human genes; broadly resetting gene expression toward a healthier, younger pattern.
M
Melanotan I
Afamelanotide ยท Scenesse
Melanotan I (Afamelanotide) is a synthetic analog of alpha-melanocyte-stimulating hormone (ฮฑ-MSH) that activates MC1R to stimulate melanogenesis. FDA-approved as Scenesse for erythropoietic protoporphyria (EPP), it increases eumelanin production providing photoprotection without UV exposure.
Melanotan II
MT-II ยท MT-2
Melanotan II is a synthetic cyclic heptapeptide analog of ฮฑ-MSH that non-selectively activates multiple melanocortin receptors (MC1R-MC5R). It produces skin tanning, sexual arousal, and appetite suppression but carries significant safety concerns due to its broad receptor activity and unregulated status.
