# PT-141 References: The Studies and Label Behind These Summaries

> The full PT-141 (bremelanotide) reference list — RECONNECT Phase 3 trials, the 52-week extension, the fMRI mechanism study, the FDA label, and the combination-pharmacology work, with DOIs and PubMed links.

Each quantitative statement on this site maps to one of these sources. Conference abstracts are noted as a lower evidence tier; the 2008 salvage study is listed with its 2023 Expression of Concern.

## How to read this list

Every cited claim on this site resolves to a numbered source below. The backbone is the peer-reviewed clinical record — the RECONNECT Phase 3 trials, the 52-week extension, the mechanistic fMRI study — together with the FDA prescribing label. Two flags travel with specific entries: conference abstracts (the 2024-2025 sexual-medicine reports) sit a tier below peer-reviewed full text, and the 2008 salvage-of-sildenafil-failures study is listed with the 2023 Expression of Concern that places its findings in dispute. Where DOIs, PMIDs, or NCT identifiers exist, they are included.

A sage-margined field notebook on the PT-141 (bremelanotide) record — the one approved indication, the modest measured benefit, and the nausea-led tolerability cost noticed first and cited to source, while the central-versus-peripheral mechanism is drawn plainly and the unverified field reports are penned in their own ruled margin; no clinic behind the notebook and nothing here dosed, dispensed, or sold.
