Leah Garner
Reads the study before the headline, and says so when the human evidence is thin or missing.
Leah Garner edits the clinical side of This Peptide: which studies exist for each peptide, who was in them, and at what dose. For many of these compounds the honest answer is that the human evidence is small, early or absent, and her pages say that in plain words rather than borrowing certainty from animal work. Every figure links to the paper, label or regulatory document it came from. No degrees, affiliations or clinical credentials are claimed here; the sourcing is the credential.
What they cover
- Human versus animal and in-vitro evidence
- Randomized trial design and endpoints
- FDA labels and approval documents
- Adverse events and dropout reporting
- Peptide dosing in published studies
