Independent Research Peptide Comparison
PeptidesRated was created to solve a simple problem: there was no honest, unbiased place to compare research peptide providers. We built the platform we wished existed.
Our Mission
To provide transparent, data-driven comparisons of research peptide suppliers based on third-party testing, verified customer reviews, and business practices—not affiliate commissions or marketing budgets.
Why We Exist
The peptide industry has a transparency problem. Too many review sites are paid promotions in disguise. Too many suppliers hide testing data or make misleading claims. Researchers deserve better.
What We Do
Verify Testing Data
We track which providers use third-party labs (Janoshik, MZ Biolabs, etc.), batch-specific COAs, and HPLC/MS testing. No testing = red flag.
Analyze Reviews
We aggregate verified customer reviews from Trustpilot, Reddit, and other sources to identify patterns—both positive and negative.
Track Pricing
We monitor per-mg pricing across providers to help you understand fair market value and spot suspiciously cheap (or expensive) outliers.
Our Standards
No Pay-to-Play Rankings
Suppliers cannot pay for better ratings or featured placement. Rankings are based solely on testing verification, customer reviews, and business practices.
Honest Red Flags
If a provider has FDA warnings, missing testing data, or terrible reviews, we say so—even if they're a big name in the industry.
Transparent Methodology
Our ratings consider: third-party lab testing (40%), customer reviews (30%), business practices (20%), and pricing transparency (10%). No secret algorithms.
Regular Updates
The peptide industry changes fast. We update provider data monthly and add new suppliers based on community requests.
Our Independence
Full disclosure: We do not accept payment from peptide suppliers for reviews or rankings. We may earn affiliate commissions if you click through to certain providers, but this does not influence our ratings or recommendations.
Our tier system (Tier 1 Recommended, Tier 2 Good Alternative, Not Recommended) is based entirely on testing verification, customer satisfaction, and transparency—not affiliate potential. If a supplier has questionable practices, we'll flag it regardless of any business relationship.
Who We Are
PeptidesRated was founded by researchers frustrated with the lack of reliable information in the peptide space. We're not affiliated with any supplier, manufacturer, or testing lab.
Our team includes:
- •Former researchers who used peptides in academic and personal research contexts
- •Data analysts who track supplier testing claims and customer feedback
- •Community moderators from peptide forums (Reddit, Discord) who understand buyer concerns
We maintain anonymity to avoid industry pressure and conflicts of interest.
