How the Atlas works

The Peptide Atlas is a reference, so it's only useful if you can trust how it was put together. This page explains the rules every entry follows.

Evidence tiers

Every entry carries one of four labels. They describe the state of the research, and nothing else.

• Established. FDA-approved, with large randomized trials behind it.
• Human-tested. Human trials exist, or the compound has a long history of clinical use, but it isn't FDA-approved for the use most people are interested in.
• Early research. A real body of laboratory and animal research, with little or no human data yet.
• Theoretical. A plausible mechanism, without meaningful study data in animals or people.

Sourcing

Every factual claim links to a primary source: the published study or trial, not a press release or another blog. We verify each reference against PubMed at the time we write it, and again whenever an entry is reviewed. When we state a count ("228 publications indexed on PubMed"), we publish the search we ran and the date we ran it, so anyone can reproduce the number.

Updates

Each entry shows its last-reviewed date. Entries get re-reviewed when new research lands, and the whole Atlas gets a full review pass yearly.

Where we stand

Pepvio is a telehealth company. Some compounds in the Atlas are ones licensed physicians prescribe through our platform, and entries for those link to the relevant program. Most entries are compounds we don't offer at all. The evidence tiers and the research summaries follow the same rules either way, which you can check: the references are right there.
