How the PeptideBase Matching Tool Works

What the Matching Tool Does

PeptideBase's matching tool is an educational questionnaire that helps you explore which peptides and providers might be relevant to your stated health goals. It is not a diagnostic tool, a prescribing platform, or a substitute for professional medical advice.

The tool works in 7 steps. Each step collects information that the matching engine uses to filter and rank educational suggestions. No account is required. Your responses are used only within your session and are not stored against your identity.

The 7 Questions

Step 1 — Primary Goal

You select your main area of interest from seven categories: recovery, performance, fat loss, cognitive enhancement, longevity, skin and joint health, or sexual health. This sets the initial category weighting for the peptide candidate pool.

Step 2 — Secondary Goal

You can optionally select a second area of interest. This expands the candidate pool to include peptides with relevance across both goals — for example, selecting both "recovery" and "longevity" would surface peptides researched in both contexts.

Step 3 — Health Flags

This is the most consequential step from a safety perspective. You indicate any relevant health background: active or prior cancer history, pregnancy or nursing, cardiovascular conditions, autoimmune conditions, liver or kidney conditions, and others.

The information you provide here directly affects which peptides appear in your results. This step is not optional — it is the mechanism by which the tool filters out peptides that are contraindicated for your stated background.

Step 4 — Location

Your country and, where relevant, your region. This is used to filter provider availability — providers that do not operate in your location are excluded from results. PeptideBase covers providers in the US, UK, Canada, Australia, and New Zealand, as well as some international options.

Step 5 — Provider Preference

Whether you are looking for a telehealth provider, a physical clinic, a compounding pharmacy, or are open to any provider type. This filters the provider results rather than the peptide results.

Step 6 — Experience Level

Your prior experience with peptide therapy, from none to experienced. This is used to contextualise your results and surface educational information appropriate to where you are in your research journey.

Step 7 — Additional Context

An optional free-text field for any additional goals or context. This informs how results are presented but does not affect the core filtering logic.

How Safety Filtering Works

The most important function the matching engine performs is silent safety filtering. When you indicate a health flag in Step 3 — for example, active cancer history — any peptides in the database that carry that contraindication are excluded from your results entirely.

You will not see a list of peptides you are excluded from. You will simply see results relevant to your stated background. This is by design: surfacing a list of contraindicated options would be both unhelpful and potentially misleading.

The contraindication data used for filtering is sourced from each peptide's research profile, which is maintained separately in the PeptideBase peptide index. The filtering is conservative — when in doubt, peptides are excluded rather than included.

What the Results Mean

Your results include two sections:

Suggested Peptides Educational profiles of peptides that are relevant to your stated goals and have passed the safety filter based on your health flags. Each profile links to the full research page for that peptide, where you can explore mechanism of action, risk profile, regulatory status, and providers who offer it.

Suggested Providers Verified providers from the PeptideBase directory that operate in your region and offer one or more of the suggested peptides. Providers are ranked by verification status and breadth of offering.

These are educational suggestions — not prescriptions, not medical recommendations, and not endorsements. The providers listed have been verified against publicly available information, confirming they are real operating businesses. Verification does not constitute a quality rating or medical endorsement.

What the Tool Is Not

It is worth being direct about what the matching tool cannot do:

It cannot diagnose any condition
It cannot tell you whether peptide therapy is appropriate for your specific situation
It cannot replace a consultation with a qualified healthcare provider
It cannot guarantee that any peptide or provider is available, legal, or appropriate in your jurisdiction

The appropriate use of this tool is as a structured starting point for your own research — not as a decision-making endpoint.

Who Should Use It

The matching tool is most useful for people who are new to researching peptide therapy and want a structured way to explore what might be relevant to their goals. If you already have a specific peptide or provider in mind, the peptide research index and provider directory may be more efficient starting points.
