GHK-Cu

ResearchAnti-Aging

A naturally occurring copper-binding tripeptide that modulates over 4,000 human genes. The gold standard in dermal remodeling, wound healing, and systemic anti-aging research.

Half-life: ~1–2 hoursDose: 1–2 mg daily

KPV

ResearchRecovery

A master anti-inflammatory tripeptide derived from alpha-MSH. Obliterates systemic inflammation at the genetic level without immunosuppression, making it a staple for IBD and gut health.

Half-life: ~30 minutesDose: 200–500 mcg

Argireline

ResearchCosmetic

The premier topical 'Botox alternative' — a hexapeptide that reduces wrinkles by interrupting neural signaling to facial muscles.

Half-life: ~4 hours (topical)Dose: Topical (5–10% serum)

Matrixyl

ResearchCosmetic

The gold standard in structural dermal remodeling. Tricks the skin into overproducing collagen by mimicking wound signals.

Half-life: ~6 hours (topical)Dose: Topical (serum formulation)

SNAP-8

ResearchCosmetic

The next-generation evolution of Argireline with two additional amino acids for deeper, more enduring anti-wrinkle efficacy.

Half-life: ~4 hours (topical)Dose: Topical (3–10% serum)

Decapeptide-12

ResearchCosmetic

A skin-lightening peptide that inhibits melanin production for even skin tone without the toxicity of hydroquinone.

Half-life: ~4 hours (topical)Dose: Topical (serum formulation)
