Peptide Directory

Anti-aging collagen stimulator widely used in anti-aging serums. One of the most well-studied cosmetic peptides with a strong track record for reducing fine lines.

"Botox in a bottle" claims surround this muscle-relaxing peptide. Marketed for expression lines, though its real-world effect is significantly more modest than injectable neurotoxins.

One of the most researched peptides in cosmetic science. Naturally occurring in human plasma, GHK-Cu declines with age and is involved in wound healing, collagen synthesis, and potentially hair growth.

Body Protection Compound-157 is popular in biohacking communities for gut healing and injury recovery. Not FDA approved and most evidence comes from animal studies.

Tissue repair peptide popular in sports recovery communities. A synthetic fragment of Thymosin Beta-4, it is banned in competitive sports and has limited human clinical data.

A collagen-boosting signal peptide most often paired with Palmitoyl Tetrapeptide-7 to form the Matrixyl 3000 complex. Popular in anti-aging formulations aimed at mature or sensitive skin.

An antioxidant dipeptide found naturally in muscle and brain tissue. Studied for its anti-glycation properties that protect proteins from sugar-related damage linked to aging.

The most mainstream peptide supplement. Collagen broken down into small, absorbable peptides for oral use. Widely studied for skin, joint, and general connective tissue support.

Prescription-only weight management peptides including Ozempic, Wegovy, and Mounjaro. The most clinically proven class of peptides for obesity and type 2 diabetes management. PRESCRIPTION ONLY.

A grouping of longevity-focused experimental peptides aimed at boosting cellular NAD+ levels, clearing senescent cells, or stimulating telomerase. Largely experimental with very preliminary human data.

A growth hormone releasing hormone (GHRH) analog popular in anti-aging and bodybuilding communities. Often combined with Ipamorelin. Not FDA approved and sold through gray-market peptide suppliers.

A selective growth hormone secretagogue (GHS) considered one of the milder GH-releasing peptides. Popular in anti-aging clinics and often paired with CJC-1295. Not FDA approved.

A modified fragment of human growth hormone (amino acids 177-191) developed for fat loss. Despite promising early research, it failed to demonstrate efficacy in large clinical trials and was not approved by the FDA.

The only FDA-approved peptide for hypoactive sexual desire disorder (HSDD) in premenopausal women, marketed as Vyleesi. Unlike other sexual dysfunction treatments, it works through the nervous system rather than the vascular system.

An immune-modulating peptide naturally produced by the thymus gland. Approved in over 30 countries (as Zadaxin) for hepatitis B and C treatment, though not FDA-approved in the US. One of the more clinically substantiated peptides in the wellness space.

A synthetic tetrapeptide studied for its potential to activate telomerase, the enzyme that maintains telomere length. Developed by Russian scientist Vladimir Khavinson and central to his theory of peptide bioregulation. Human evidence is very preliminary.

A synthetic peptide derived from the naturally occurring immunomodulatory peptide tuftsin, developed at the Institute of Molecular Genetics in Russia. Approved in Russia as an anxiolytic and nootropic. Gaining interest in Western biohacking communities for anxiety and cognitive support.

A synthetic peptide analog of ACTH (adrenocorticotropic hormone) fragment 4-10, developed in Russia for neuroprotection and cognitive enhancement. Approved in Russia and Ukraine for stroke recovery and cognitive disorders. Popular in the nootropic community worldwide.

An extended version of Argireline (from 6 to 8 amino acids) marketed as a more potent "Botox alternative" for expression lines. Targets the same SNARE complex mechanism but claims improved efficacy through the additional amino acids.

An anti-inflammatory signal peptide most commonly found paired with Palmitoyl Tripeptide-1 in the Matrixyl 3000 complex. While Palmitoyl Tripeptide-1 stimulates collagen production, Tetrapeptide-7 works to reduce inflammation and skin damage from UV exposure.
