Melanotan I
ClinicalClinical-grade melanocyte activator for photoprotection
Melanotan I (afamelanotide) is a synthetic analogue of alpha-melanocyte-stimulating hormone (α-MSH) that potently stimulates melanogenesis, increasing skin pigmentation without requiring UV exposure. It was developed primarily to protect individuals with photosensitive conditions such as erythropoietic protoporphyria (EPP) from painful phototoxic reactions. Beyond tanning, it has demonstrated anti-inflammatory, photoprotective, and potentially immunomodulatory effects in clinical and preclinical studies.

AHK-Cu
Human-limitedCopper peptide for skin regeneration and repair
AHK-Cu is a copper-binding tripeptide (Ala-His-Lys) complexed with copper(II) ions, closely related to the well-studied GHK-Cu peptide. It stimulates collagen and glycosaminoglycan synthesis in skin fibroblasts while exerting antioxidant and anti-inflammatory activity. Primarily researched in the context of skin regeneration, wound healing, and hair follicle stimulation.

LL-37
Human-limitedHuman antimicrobial peptide for immunity and healing
LL-37 is a 37-amino acid human host defense peptide derived from the cathelicidin family, naturally produced by neutrophils, epithelial cells, and macrophages. It exhibits broad-spectrum antimicrobial activity against bacteria, fungi, and viruses while simultaneously modulating immune responses and promoting wound healing. Research suggests it plays a critical role in innate immunity and may have therapeutic applications in chronic infections, wound repair, and inflammatory conditions.

Melanotan II
Human-limitedPotent tanning and libido melanocortin agonist
Melanotan II (MT-II) is a synthetic cyclic heptapeptide analogue of alpha-melanocyte-stimulating hormone (α-MSH) originally developed at the University of Arizona. It potently activates melanocortin receptors to stimulate skin tanning, increase sexual arousal, and suppress appetite. Unlike natural α-MSH, its cyclic structure confers greater receptor affinity and metabolic stability.

Snap-8
Human-limitedPeptide wrinkle relaxer targeting neuromuscular signaling
Snap-8 is a synthetic octapeptide cosmetic active designed to reduce the appearance of expression lines and wrinkles by modulating neuromuscular signaling at the dermal-muscle interface. It is an extended analog of Argireline (Acetyl Hexapeptide-3) with two additional amino acids, offering purportedly enhanced efficacy. Originally developed for topical cosmetic application, it has also been explored in research-grade injectable formulations for more direct tissue delivery.

GLOW (BPC-157 + GHK-Cu + TB-500 Blend)
AnimalRegenerate, Renew, Glow From Within
GLOW is a synergistic peptide blend combining BPC-157 (10mg), GHK-Cu (50mg), and TB-500 (10mg) into a single formulation designed to accelerate tissue repair, promote skin rejuvenation, and support systemic recovery. BPC-157 and TB-500 target musculoskeletal and gut healing, while GHK-Cu drives collagen synthesis, anti-inflammatory signaling, and skin remodeling. Together, these three peptides work across complementary pathways to produce enhanced regenerative and cosmetic outcomes.
