About Peptide File

Independent. Evidence-rated. No selling.

What is Peptide File?

Peptide File is an independent research site covering peptides, GLP-1 receptor agonists, and related compounds in clinical science. We compile, rate, and summarise the published evidence — so you can make sense of what the data actually says.

We are not affiliated with any pharmaceutical company, supplement brand, or clinic. We do not sell compounds. We do not give medical advice.

Why we built this

The peptide and GLP-1 space moves fast. Trial data, FDA timelines, and mechanism research are scattered across PubMed, press releases, and paywalled journals. Most of what you find online is either promotional content or forum speculation.

Peptide File exists to fill that gap — structured, referenced research summaries written for people who want to understand the science, not just the hype.

How we rate evidence

Every compound on this site is assigned an evidence rating based on the volume, quality, and consistency of published research:

StrongMultiple randomised controlled trials (RCTs) or large Phase III clinical trials with consistent, replicated results.
ModerateLimited RCTs, observational studies, small clinical trials, or mixed results across studies.
EmergingPrimarily animal data, in vitro studies, case reports, or very early-phase human trials. Promising but not yet established.

Evidence ratings are not endorsements. A strong evidence rating means the research base is solid — it does not mean a compound is safe or appropriate for any individual.

Editorial independence

Peptide File is editorially independent. We are not funded by, or affiliated with, any pharmaceutical company, clinic, supplement retailer, or compounding pharmacy. No company pays us for editorial coverage. If that ever changes, we will say so clearly.
