About
Built by researchers,
for researchers.
The peptide research space is full of noise—affiliate sites pushing whoever pays the highest commission, Reddit threads with conflicting advice, and vendors making claims they can't back up.
We're building something different. PeptideRanker is an independent resource focused on one thing: helping you find reputable, quality-tested vendors for your research needs.
Our team has years of experience in health and wellness digital publishing. We understand the compliance landscape, and we're committed to presenting information responsibly—all products featured are for laboratory research purposes only.
No pay-to-play rankings. No sponsored placements. Just honest, research-backed comparisons.
Research Use Only
All peptides and vendors featured on PeptideRanker are intended for legitimate laboratory and research purposes only. We do not provide medical advice or encourage human consumption.
