Editorial policy

What “best” means. Best means the strongest published evidence that a peptide helps with a goal. It doesn’t mean safe, and it doesn’t mean right for you. We rank by the type of evidence first, then its quality and its result. A rank isn’t a recommendation. If no peptide has good evidence for a goal, we say so.

Types of evidence.

• Human trials: controlled trials in people, published in a journal, that tested a clinical outcome and showed a benefit. The strongest kind of evidence we report.
• Limited human data: small, short or inconclusive human studies, including observational studies, uncontrolled trials and controlled trials that did not show a clinical benefit.
• Animal studies: results in animals often don’t carry over to people.
• Lab studies: cells or tissue in a dish. An early signal, not an answer.

What our labels mean.

• FDA-approved: the FDA approved a specific product for the uses on its label. That doesn’t extend to compounded versions or other uses.
• Compounded versions: not FDA-approved: generally made by a pharmacist or physician for an individual patient. Compounded drugs are not FDA-approved, which means the FDA doesn’t review their safety, effectiveness or quality before they’re marketed.
• Investigational: being studied in people, and not FDA-approved for that use.
• Animal studies only: we found no published human studies as of the date we checked.

Sources and checks. Every factual claim links to its source. We prioritize FDA, PubMed, ClinicalTrials.gov, peer-reviewed journals and primary press releases. When we rely on a secondary source, we link to it. Each guide is checked against its cited sources before it’s published. U.S. regulatory status is checked on the day of publication, and the date appears on the page. Status can change after that date.

What we don’t publish. We don’t publish doses, cycles or mixing instructions for unapproved peptides. For approved medicines, we point to the FDA label and a clinician. We don’t promise cures or results, and we don’t publish before-and-after claims. We don’t link to or recommend “research use only” or gray-market sellers for human use.

Who writes this. Guides carry the byline of the Best Peptides For Editorial Team. We use AI tools to help research, write and check our pages. A “Reviewed by” line appears only when a named person actually reviewed the page, with the date.

Corrections. When we find an error, we correct the guide in place, update its date and list it on our corrections page.

Commercial relationships. Any commercial relationship is disclosed clearly, next to the content it touches.
