How PeptideBase Works

The PeptideBase matching flow is a 7-step questionnaire that collects your research goals, health context, age range, lifestyle factors, and preferences around administration and protocol type.

Your answers are run through a two-stage scoring engine. The first stage applies hard filters: peptides with contraindications that overlap with any health flags you reported are excluded entirely from your results. The second stage ranks remaining peptides into three research-relevance tiers based on how closely they align with your stated goals.

Providers are then scored against your matched peptides. Only verified providers that carry at least one of your matched peptides are eligible to appear in results. Providers are ranked by how many of your matched peptides they carry, weighted by tier relevance and verification status.

If no providers meet the quality threshold for your specific match, the engine returns a no strong match result rather than surfacing weak or speculative recommendations. This is intentional.

Match results are educational outputs — not treatment recommendations, protocols, or clinical advice. They are a starting point for your own research.

A provider marked Verified has been manually reviewed by the PeptideBase team. Verification confirms that:

• The provider is a real, operating business or practice
• The listed peptides and services match public information about the provider
• The provider information on PeptideBase is accurate to the best of our knowledge at the time of review

Verification does not constitute an endorsement. It does not mean PeptideBase has evaluated the provider's clinical practices, product quality, regulatory compliance, or safety record. Verified status is a data-accuracy signal, not a quality or safety rating.

Providers without the Verified badge have been added to the directory but have not yet completed the review process. Their listings may be less complete or may contain errors.

Provider ratings shown on PeptideBase are sourced from third-party review platforms — for example, Google Reviews, Trustpilot, or similar. Where a rating is displayed, the source platform is listed alongside it.

PeptideBase does not collect, solicit, or aggregate its own first-party reviews. Ratings are not adjusted, normalised, or editorially influenced by PeptideBase.

A provider without a rating displayed has not had a third-party rating sourced yet — it does not indicate a poor or unreliable provider. Ratings are supplemental data, not a primary ranking factor.

PeptideBase is: an educational provider directory and research reference tool. It helps you find providers, understand what peptides they carry, and get a structured starting point for your research based on your goals and health context.

PeptideBase is not: a medical service, telehealth platform, prescribing tool, or clinical advisory service. Nothing on this site constitutes medical advice, a treatment recommendation, a diagnosis, or a protocol.

Peptide compounds discussed on PeptideBase are primarily research chemicals. Their safety, efficacy, and regulatory status vary by compound, jurisdiction, and use context. Always consult a qualified healthcare provider before making any decisions related to your health.
