Where do you actually go for real peptide information? Not YouTube influencers, not Reddit anecdotes: actual sources. These are the resources we use and trust, ranked by how useful they actually are.
How we evaluated: This page records the public sources reviewed for each entry and states the limits of those records.
Official registry of clinical trials. The ultimate reality check against peptide hype.
What we verified
Confirmed live with 592,901 studies. BPC-157 has only 2 trials. 'Peptide' returns 7,166 studies with 591 recruiting.
COA claims
Full trial registry with enrollment data, phase, sponsor, and results. Searchable by compound name, condition, or sponsor.
Community notes
Frequently cited on r/Peptides as the reality check against anecdotal hype. The gap between community claims and actual trial counts is often shocking.
The good
Official government database
Definitive trial status data
Free and public
Searchable by any compound
The bad
Clunky interface
Many research peptides have zero or minimal trials
Not designed for consumers
Verdict
The most important resource on this list. Before believing any peptide claim, check if there's actually a trial. If there isn't, that tells you something.
Supplement and compound evidence aggregator with referenced summaries.
What we verified
BPC-157 page exists, last updated Sept 2025. Authored by credentialed writers. However, many research peptides (TB-500, semax, etc.) have no pages at all.
COA claims
Evidence summaries with cited sources. Covers supplements and some compounds. Human, animal, and in vitro evidence separated.
Community notes
Recommended as a starting point on Reddit. Users appreciate the source-cited approach. Frustration with missing peptide pages is common.
The good
Source-cited evidence summaries
Credentialed writers
Separates human/animal/in vitro evidence
Good for mainstream supplements
The bad
Many research peptides have no pages
Limited depth on peptide-specific topics
Not updated frequently enough
Premium tier for full access
Verdict
Great for mainstream supplements (creatine, NAD+) but thin on research peptides. Check it for established compounds, but don't expect TB-500 or semax coverage.
Active community for anecdotal reports and vendor discussion. High noise, some signal.
What we verified
Reddit blocked automated access but r/Peptides is one of the most active peptide communities online.
COA claims
Community-driven vendor reviews, COA sharing, and anecdotal experience reports. No editorial oversight: raw community discussion.
Community notes
It's a community: take everything with skepticism. Vendor recommendations are heavily biased by personal experience. But the collective COA-sharing has exposed bad batches.
The good
Active community
Real user experiences
COA sharing culture
Vendor reputation tracking
The bad
High noise-to-signal ratio
No editorial oversight
Vendor shilling is common
Anecdotes are not evidence
Verdict
Useful for vendor reputation signals and COA sharing: but never as your only source. Cross-reference everything with PubMed and ClinicalTrials.gov.
Was a research protocol. Now a supplement store. Overrated for research.
What we verified
Visited the site: it has pivoted from a public protocol to a supplement e-commerce platform. Products are $39-49. No longer functions as a research resource.
COA claims
Sells supplements. The original protocol transparency data is no longer the focus.
Community notes
Bryan Johnson is frequently mentioned in longevity communities. His protocol brought attention to rapamycin and other compounds. But the site itself is no longer a research resource.
The good
Brought mainstream attention to longevity compounds
Some original protocol data still exists
High production value content
The bad
Now a supplement store, not a research resource
No peer-reviewed content
Commercial bias is obvious
Not peptide-specific
Verdict
Skip this as a research resource. The brand brought attention to longevity peptides but the site itself now sells products, not information.
