Evidence Log
Ratings change. Here's the receipt.
A registry that never revises anything isn't following evidence — it's defending a position. Every change to an evidence level is logged with the reason behind it.
Evidence-level changes
- Registry-wideL2Preclinical
Editorial update: registry expanded from 42 to 56 curated compounds, adding major approved peptide medicines across oral, nasal, injectable and implant routes, plus a source-completeness layer on every profile.
This is a registry coverage change, not a new clinical discovery. Fourteen established medicines — from desmopressin and oxytocin to linaclotide and icatibant — were added so that approved peptide therapy across routes can be compared against research-market claims. Each profile now also shows whether its references are fully curated, partially curated or still pending, and outstanding placeholders (e.g. vasopressin, calcitonin) are marked openly rather than filled with weak links.
- Registry-wideL2Preclinical
Editorial update: major taxonomy expansion from 15 to 42 curated compounds, adding approved peptide medicines and high-interest research compounds.
This is a registry coverage change, not a new clinical discovery. New categories (metabolic, gastrointestinal, bone-calcium, melanocortin, immune, antiviral, pain-neuro) and a new route (intrathecal) were added so that approved medicines — from bremelanotide to ziconotide — can be catalogued alongside the research compounds they are constantly confused with.
- L1Mechanistic
Editorial update: profiles created or revised using FDA 2026 Pharmacy Compounding Advisory Committee material.
This reflects curation of existing regulatory documents, not new clinical findings. FDA 2026 PCAC review material established, for example, that no clinical studies or human exposure data were identified for KPV via any route — a fact that sets the ceiling for every marketed claim about it.
- L2Preclinical
Baseline entry: registry position set to preclinical-only for musculoskeletal healing claims.
Reviewed the available literature landscape. Preclinical breadth is large; controlled human evidence for tendon and injury claims remains absent, so confidence stays very low.
- L3Early humanrating moved
Baseline entry: split rating into approved narrow indication versus general anti-ageing claims.
A rare-disease accelerated approval justifies a higher regulatory status but not higher confidence in longevity or performance claims. The registry now separates the two explicitly.
- L4Strong humanrating moved
Baseline entry: efficacy confidence for weight loss set high; safety confidence held low pending Phase 3 completion.
Randomised human trial data support large weight reduction. Long-term safety and a regulatory decision are still outstanding, so the two axes are rated separately.
- L2Preclinical
Baseline entry: classified as promising-but-unproven rather than emerging therapy.
Human data are observational. Without a published trial of exogenous administration, therapeutic claims cannot rise above Level 2.
- L3Early humanrating moved
Baseline entry: topical and systemic evidence separated into distinct positions.
Small topical cosmetic studies support modest skin-appearance effects. Injectable systemic use has no controlled human evidence and is rated independently.
- L2Preclinical
Baseline entry: discontinued clinical development recorded in the profile.
Trials in postoperative ileus did not meet endpoints and development stopped. Physique claims have never been trialled.
- L4Strong human
Baseline entry: added as combination-therapy candidate with moderate confidence.
Additive weight reduction in combination trials is supported. Standalone long-term evidence remains limited.
- L1Mechanistic
Baseline entry: lifespan-extension claims recorded as unsupported.
Supporting literature is historical, narrow and largely unreplicated. Mechanistic telomerase findings do not establish human outcomes.
Notable regulatory events

United States
FDA granted accelerated approval to Wegovy for adults with noncirrhotic MASH with moderate-to-advanced liver fibrosis (F2-F3).
United States
FDA approved Zepbound as the first medication for obstructive sleep apnoea in adults with obesity.
China
NMPA approved mazdutide for chronic weight management. A regional approval; not approved in the US, UK or EU.
