Every provider, scored.
Behind every listing is a structured trust profile — objective criteria scored across verification, reviews, telehealth coverage, and peptide range. Ranked by data, not revenue.
- Verification status confirmed independently
- Review data aggregated across platforms
- Telehealth reach and peptide breadth scored
- No commercial relationships — rankings are purely algorithmic

Combinations in the literature.
GHK-Cu + Epithalon: Anti-Aging
A longevity-focused stack pairing GHK-Cu's tissue rejuvenation and antioxidant gene activation with epithalon's proposed telomere-lengthening and pineal gland regulatory effects. GHK-Cu resets gene expression toward a younger phenotype by activating antioxidant and anti-inflammatory gene networks, while epithalon is proposed to slow cellular ageing by stimulating telomerase and regulating circadian and neuroendocrine function. The combination addresses anti-aging at both the cellular replication and tissue maintenance levels.
MOTS-c + SS-31: Mitochondrial Optimization
A mitochondrial-targeted combination pairing two peptides with distinct but complementary mechanisms. MOTS-c enhances glucose metabolism and AMPK signaling while SS-31 (Elamipretide) stabilizes cardiolipin in the inner mitochondrial membrane, protecting against oxidative damage. Researched in contexts of aging, metabolic dysfunction, and exercise performance.
Thymalin + Epithalon: Immune-Longevity Protocol
Both Thymalin and Epithalon are short bioregulatory peptides developed by Vladimir Khavinson and studied across decades of Russian gerontological research. Thymalin is associated with thymic peptide function and immune regulation in aging populations; Epithalon with pineal peptide activity, melatonin normalization, and telomere elongation. The combination is commonly referenced in longevity research for its dual immune-modulating and anti-aging mechanistic rationale.

Our methodology
Ranked by verification, not revenue share.
Every provider is scored across four objective criteria. No commercial relationship affects ranking. Smart sort is the default — it surfaces verified, reviewed providers first.

How PeptideBase Verifies Providers
The PeptideBase directory lists 3,136 active providers. Here's exactly what we check — and what we don't — before we assign a verified badge.
Five Signals That a Longevity Research Project Is Worth Your Time
PeptideBase analyzed 545+ longevity providers to identify the signals that separate credible DeSci research projects from noise. Here's the framework.

No. PeptideBase is an educational directory and matching tool. We aggregate publicly available information about providers and compounds. Nothing on the platform is a prescription, treatment plan, or substitute for consultation with a licensed clinician.
Smart sort weights four objective signals: verification status (35%), rating & review data (25%), telehealth coverage (20%), and peptide breadth (20%). You can re-sort by any single criterion at any time.
No. Provider rankings are determined by a documented algorithmic scoring system — verification status, review data, telehealth availability, and peptide breadth. No provider can pay to influence their ranking.
Clinics employ licensed practitioners who can prescribe. Compounding pharmacies (503A / 503B) formulate and dispense against a prescription. Vendors sell compounds for research use only — no prescription, no medical guidance, and not for human consumption.
A small number — Semaglutide and Tirzepatide among them — are FDA-approved for specific indications. Most peptides catalogued on PeptideBase are not FDA-approved and are dispensed under compounding exemptions or sold for research. Each peptide page lists its current regulatory status.
The 7-question quiz runs entirely client-side. No account is required to receive a match. We log aggregate, anonymized response distributions to improve the matching model — never tied to an identity. You can review the data we collect on our privacy page.
