A to Z Index · Healing & Repair Peptides · Growth Hormone Secretagogues · Bioregulator Peptides · Cosmetic & Skin Peptides · Metabolic & Weight Peptides · Human Trials
- AHK-CuLibrary entryA copper tripeptide (Ala-His-Lys) studied in hair-follicle models; no human administration study is cited.
- Argireline (Acetyl Hexapeptide-3/8)Library entryA topical hexapeptide that mimics part of SNAP-25 to soften expression lines; tested in small randomized cosmetic trials.
- GHK (Copper-Free)Library entryThe natural tripeptide Gly-His-Lys without copper bound; the copper complex GHK-Cu has its own page.Conditions: Acne, Anti-aging & longevity, Atherosclerosis, cardiovascular disease & high blood pressure, Bell's palsy
- GHK-Cu (Copper peptide)Library entryA copper-binding tripeptide present since birth.Conditions: Anti-aging & longevity, Skin, hair loss, wounds & mast-cell/histamine reactivity, Tendon, ligament, muscle & joint injuries (incl. athletes), Kidney protection (CKD, diabetic kidney, lupus kidney)
- GLOW Blend (GHK-Cu + BPC-157 + TB-500)Library entryA three-peptide research blend sold in one vial: GHK-Cu, BPC-157 and TB-500. No published human trial has tested the combination.
- Leuphasyl (Pentapeptide-18)Library entryA cosmetic pentapeptide (Tyr-D-Ala-Gly-Phe-Leu) modeled on enkephalins, sold to soften expression lines, often alongside Argireline.

- Melanotan ILibrary entryA synthetic melanotropin (α-MSH analog), afamelanotide, studied for pigmentation; the approved product is an implant.Conditions: Acne, Concussion, traumatic brain injury & stroke recovery, Skin, hair loss, wounds & mast-cell/histamine reactivity
- Melanotan IILibrary entryA synthetic cyclic α-MSH analog that can stimulate skin pigmentation; regulators warn about serious adverse effects of unapproved products.Conditions: Sexual function & libido (women and men), Skin, hair loss, wounds & mast-cell/histamine reactivity
- PTD-DBMLibrary entryA cell-penetrating peptide that blocks CXXC5 binding to Dishevelled, boosting Wnt signaling; studied for hair regrowth in mice.
- SNAP-8Library entryAn eight-amino-acid cosmetic peptide (acetyl octapeptide-3) studied in formulations aimed at the appearance of wrinkles.
- Syn-Ake (Dipeptide Diaminobutyroyl Benzylamide Diacetate)Library entryA cosmetic dipeptide derivative modeled on a pit-viper venom peptide (waglerin-1), sold for wrinkle creams; topical use only.
- Tripeptide-29 (Collagen Tripeptide)Library entryThe collagen tripeptide Gly-Pro-Hyp, used in cosmetics and oral collagen supplements for skin hydration and elasticity.Conditions: Eczema, Skin, hair loss, wounds & mast-cell/histamine reactivity
