Evidence snapshot

This drawer marks papers. It is not a plan, a dose, or a source. A paper is a bounded report. It is not a protocol. Grades name the object. They are not a safety rating.

Identity lock. PT-20 could not be locked to a single, unambiguous peptide object from PubMed / PubChem in this pass. Checklist adjacency to PT-10 / PT-141 does not define chemistry. No credible CAS / CID / sequence consensus was found for a peptide specifically named PT-20 in indexed biomedical literature during this search. PT-20 ≠ PT-141; ≠ PT-10 (also unresolved). PubChem CID / formula / CAS: To be confirmed. This drawer marks the identity gap. It is not use advice.

Bottom line

Identity unresolved. Few or no object-matched PMIDs. Refuse any efficacy grade until identity is confirmed analytically (sequence, intact mass, CAS).

Papers

No object-matched Primary papers are graded in this pack. Broad PubMed string hits on “PT-20” resolve to unrelated biology (not a characterized peptide therapeutic object) and are not listed as evidence.

What is not established

Chemical identity of PT-20. Any human or preclinical efficacy attributable to a defined PT-20 peptide. Relationship to PT-10 or PT-141 beyond shared “PT-” prefix noise. This drawer does not provide use advice, schedules, or sourcing.
