Research Peptide Profiles
Melanotan II
Skin, Hair & Aesthetics
Melanotan II is a tanning peptide that stimulates melanin production to darken skin without sun exposure. It also has effects on libido and appetite suppression.
Melanotan 1 (Afamelanotide)
Skin, Hair & Aesthetics
Melanotan 1 (Afamelanotide) is a tanning peptide that may darken skin by stimulating melanin production. Unlike Melanotan II, it's FDA-approved under the brand Scenesse for a rare sun sensitivity disorder.
GHK-Cu (Copper Peptide)
Skin, Hair & Aesthetics
GHK-Cu is a copper peptide that may improve skin health, promote wound healing, and stimulate collagen production. It's used both as an injection and in topical skincare products.
SNAP-8 (Acetyl Octapeptide-3)
Skin, Hair & Aesthetics
Snap-8 is a cosmetic peptide that may help reduce wrinkles by relaxing facial muscles, similar to how Botox works but in a topical cream form. It's commonly found in anti-aging skincare products.
Matrixyl (Palmitoyl Pentapeptide-4)
Skin, Hair & Aesthetics
Matrixyl is a collagen-boosting skincare peptide that may help reduce wrinkles and improve skin firmness. It signals your skin to produce more collagen, the protein that keeps skin looking young.
Argireline (Acetyl Hexapeptide-3)
Skin, Hair & Aesthetics
Argireline is a topical anti-wrinkle peptide that may help smooth expression lines by reducing muscle contractions in the face. It's often called 'Botox in a bottle' and is found in many skincare products.
AHK-Cu
Skin, Hair & Aesthetics
AHK-Cu is a copper peptide that may promote hair growth and reduce hair loss by stimulating hair follicle cells. It's being studied as a topical treatment for thinning hair.
About the Directory
How the Research Peptides Directory Works
The PeptideWiki directory organizes research peptides into clear, evidence-based profiles covering mechanisms, dosing, safety, and research status. Browse by category, development stage, or peptide name to compare compounds across weight loss, recovery, growth hormone, cognition, longevity, and more.
Categories
Peptides are grouped by their primary research focus and biological activity, including metabolism, growth hormone signaling, tissue repair, cognition, inflammation, aesthetics, cellular health, sexual health, and endocrine function.
Development Stage
Shows how far a peptide has progressed in the research pipeline. Preclinical compounds are still in laboratory or animal models. Phase 2, 3, and 4 compounds have moved further through human research. Discontinued compounds are no longer being actively developed.
Regulatory Approval
Shows whether a peptide has been cleared by a health authority or is still limited to research. "Not Approved" means no clinical clearance. "Investigational" means still under study. "FDA Approved" means cleared in the United States for specific indications.
