Upload your genetic, epigenetic, and blood biomarker data. PeptideDx matches it against a research-curated peptide knowledge base and returns personalized, evidence-linked recommendations.
PeptideDx exists to answer a question the field rarely asks with rigor: how do peptides actually change measurable, data-driven biomarkers? We believe that answer shouldn't be locked behind a paywall or guessed from anecdotes — it should be built openly, from real data, and given back to the people who make it possible.
We focus on objective biomarkers — genomic, epigenetic, and blood — not marketing claims. Every recommendation is tied to what your biology actually shows.
Each member who shares de-identified results makes the whole picture clearer. We pool that collective signal to see what's genuinely working — across goals, genotypes, and biomarkers.
The insight generated by the community flows back to the community. The core analysis is, and will remain, free — because the goal is knowledge, not gatekeeping.
Your data stays private and yours to delete. The collective learning it helps create belongs to everyone. That's the trade we think is worth making — and why the analysis is free.
PeptideDx cross-references multiple data layers so recommendations reflect the whole picture — not a one-size-fits-all list.
Choose the outcomes that matter to you and see peptides scored and prioritized against your selections and lab values.
Upload raw genetic data to add a compatibility layer that flags favorable, mixed, or reduced-response variants per peptide.
Contraindication and allergy screens exclude peptides that may not be appropriate for you before anything is recommended.
Each recommendation carries research citations so you and your provider can review the underlying rationale.
Come back after each round of testing to see how your biomarkers and biological age are trending as your protocol evolves.
Your uploads power your results and nothing else. Delete your stored data from your profile whenever you choose.
Members get a searchable library of primary literature — thousands of papers organized by peptide — behind every recommendation, so you can read the science yourself.
See de-identified, aggregate patterns from the community: what people take, how they rate it, and which genotypes and biomarkers respond best — available once you register.
Your report now leads with EMRAge — a biological-age biomarker validated in ~31,000 people and published in Nature Aging (2026). It reads the routine values already on your blood panel and tells you whether you're aging faster or slower than the calendar. Free with your account, and the perfect baseline to track as peptides move your biomarkers.
A free account unlocks tools you won't find on a typical peptide site: the primary science, a searchable evidence explorer, and the collective signal from everyone using it.
Thousands of primary papers, curated and organized by peptide — the same literature that informs your recommendations. Search by compound, open any study, and read the evidence for yourself. Most peptide sites give you marketing; we give you the source material.
See what's actually working across the community — which peptides people take for which goals, how they rate their own response, and which gene variants and biomarkers track with the best outcomes. Every figure is de-identified and only shown once enough members contribute, so no individual is ever exposed.
Search any goal — like athletic performance — to see every peptide with data behind it, or any lab marker — like HDL-C — to see which peptides have been shown to move it, and in which direction. Each result carries an honest evidence tier and links straight to the primary papers on PubMed.
