About these PT-141 references

These are the full PT-141 references behind every claim on this site. Each numbered entry maps to the inline markers used across the pages. Sources include peer-reviewed journals (via PubMed), the US prescribing information for bremelanotide (via DailyMed/FDA), and two recent reviews. Where a study's integrity has been formally questioned, that is noted in the text that cites it. Quantitative claims — doses, percentages, half-lives, sample sizes — each trace to an entry below.
