🛡️Immune Support

Peptides that modulate immune function, enhance antimicrobial defense, and support immune system balance through thymic function and innate immunity pathways.

Semax

Relevance: 10/10Nootropic / Neuroprotective Peptide

A synthetic heptapeptide derived from ACTH(4-10) with a Pro-Gly-Pro C-terminal extension, used as a nootropic and neuroprotectant with regulatory approval in Russia for stroke and cognitive disorders.

Thymosin Alpha-1

Relevance: 10/10Immune Modulating Peptide

A 28-amino acid thymic peptide that modulates immune function, approved in multiple countries for hepatitis B and used as an immune enhancer in cancer and infectious disease.

Thymalin

Relevance: 10/10Immune / Bioregulatory Peptide

A thymic peptide bioregulator developed in Russia that restores immune function by promoting T-cell maturation and has shown anti-aging effects in clinical studies on elderly patients.

Thymulin

Relevance: 10/10Immune / Thymic Peptide Hormone

A zinc-dependent nonapeptide hormone produced by thymic epithelial cells that plays an essential role in T-cell differentiation and immune regulation, declining significantly with age.

Selank

Relevance: 9/10Anxiolytic / Nootropic Peptide

A synthetic heptapeptide anxiolytic derived from the endogenous immunomodulatory peptide tuftsin, with an added Pro-Gly-Pro C-terminus, approved in Russia for anxiety and neurasthenia.

VIP

Relevance: 9/10Neuropeptide / Immunomodulatory Peptide

A 28-amino acid neuropeptide with broad immunomodulatory, vasodilatory, and anti-inflammatory effects, used in CIRS (Chronic Inflammatory Response Syndrome) protocols and researched for pulmonary conditions.

Tesamorelin

Relevance: 6/10Growth Hormone Secretagogue (GHRH Analogue)

An FDA-approved synthetic analogue of growth hormone-releasing hormone (GHRH) with a trans-3-hexenoic acid modification, indicated for HIV-associated lipodystrophy and studied for cognitive benefits and visceral fat reduction.

Larazotide

Relevance: 6/10Gut Health / Tight Junction Regulator

A synthetic octapeptide that regulates intestinal tight junctions, developed as the first drug to target intestinal permeability ('leaky gut') in celiac disease and other conditions.

TB-500

Relevance: 5/10Healing & Recovery Peptide

A synthetic version of the naturally occurring 43-amino acid peptide Thymosin Beta-4, widely used for tissue repair, wound healing, reduced inflammation, and improved flexibility.

FOXO4-DRI

Relevance: 5/10Senolytic Peptide

A D-retro-inverso peptide that selectively induces apoptosis in senescent cells by disrupting the FOXO4-p53 interaction, representing a targeted senolytic approach to aging.

BPC-157

Relevance: 4/10Healing & Recovery Peptide

A 15-amino acid synthetic peptide derived from human gastric juice that promotes healing of tendons, ligaments, muscles, gut lining, and other tissues through multiple regenerative pathways.

GHK-Cu

Relevance: 4/10Copper Peptide / Skin & Healing Peptide

A naturally occurring copper-binding tripeptide that declines with age, known for potent wound healing, collagen stimulation, anti-aging skin effects, and hair growth promotion.

Melanotan I

Relevance: 3/10Melanocortin Peptide

A synthetic analog of alpha-melanocyte stimulating hormone (α-MSH) that stimulates melanin production for photoprotection, FDA-approved (as Scenesse) for erythropoietic protoporphyria (EPP).
