Unmeasured means there is not enough evidence to decide. How these checks work
Start using Peptide Library

For several components dissolved together in one volume: each component's concentration and its share of the blend by amount. Arithmetic only; it says nothing about whether components can or should be combined.
DiscoveredSide-by-side research comparison of 2-3 peptides on structured profile fields: mechanism and targets, research areas, evidence level and human-trial availability, safety and side effects, FDA/WADA status, half-life and studied routes, with references. Each row says whether the values are the same, different, partial, not comparable or incomplete; missing data is never filled in and the comparison never ranks peptides. Suitable for tables. No dosing information.
DiscoveredConvert an amount between mg and mcg exactly. IU ↔ mass conversion only works with a peptide whose profile documents an IU-per-mg factor (pass `peptide`); otherwise the result is an iu_factor_missing issue, never an assumed factor. Pure arithmetic: not a dosing recommendation.
DiscoveredPrice arithmetic for a purchase: total cost (price plus optional shipping) and cost per mg, per mcg and (with a peptide's documented factor) per IU. Uses only the numbers given; it never estimates prices or shipping and converts no currencies.
DiscoveredWhat reviewed human research shows for one peptide, claim by claim: each claim under investigation, its GRADE certainty per outcome (or that it is not yet assessed), the distinct human studies assessed and the evidence gaps, with links to every assessment. Only published assessments, each marked automated (AI, not human-reviewed) or reviewed. Never dosing or administration guidance.
DiscoveredThe reviewed record of one distinct human study (id like PLS-00001, from get_evidence_summary): design, planned and actual participants, groups, outcomes as the authors reported them, the authors’ conclusion kept apart from the limitations and risk of bias Peptide Library assessed, and links to every source. No dose figures or administration details.
DiscoveredList the Peptide Library research categories (e.g. GLP-1/Metabolic, Cognitive, Longevity) with a description, the number of profiles and every profile in each, with links. Use a category id with search_peptides to filter.
DiscoveredFull educational research profile for one peptide: classification, mechanism and targets, research areas, evidence by tier (regulatory label, controlled human trials, other human studies, secondary reports, animal and in-vitro research) with cited sources, safety and side effects, regulatory status (FDA, WADA), review dates and the canonical Peptide Library URL. Fields the profile lacks are "not_documented". Dose figures and administration instructions are never included.
DiscoveredThis week's most-researched peptides in the Peptide Library community (Trending Now, last 7 days): rank, share of researchers and growth as percentages, with what moved. Aggregate and privacy-preserving: no head counts, no individual activity, small cohorts suppressed. Popularity is not evidence of safety or effectiveness.
DiscoveredSearch the Peptide Library research database by name, synonym or alias (fuzzy), optionally filtered by research category or research area. Returns short educational profiles with evidence level and the canonical Peptide Library URL. Use get_peptide_details for the full profile. No dosing information.
DiscoveredSearch Peptide Library's own educational content: the site FAQ, per-peptide FAQs, published articles and free courses. Returns titles, short snippets and links with source attribution (no full text, no third-party articles). Dosing, reconstitution and injection guides, and content about buying, vendors or prices, are excluded.
DiscoveredConcentration of an amount dissolved in a volume of liquid (amount ÷ volume), as mg/mL, mcg/mL and, with a peptide's documented factor, IU/mL. Pure arithmetic on the given numbers: it does not suggest amounts, volumes or how to prepare anything.
