About Merit Peptides
We exist to raise the standard for research-grade peptides. Every compound we sell is verified, documented, and manufactured in the USA — because the integrity of your research depends on the integrity of your materials.
Our Standards
Purity
Every batch is tested to 99%+ purity by independent laboratories using HPLC and mass spectrometry. We never release a compound that does not meet our minimum purity threshold. No exceptions.
Transparency
Full Certificates of Analysis are published for every batch on our website. We believe researchers should be able to verify purity data before they order — not after. Open documentation is foundational to trust.
Consistency
Our manufacturing partners follow cGMP guidelines in independently audited US facilities. Every production run is controlled, documented, and reproducible — so your research results are too.
How We Source, Test & Ship
From synthesis to delivery, every step in our process is designed to protect compound integrity and give researchers confidence in their materials.
All compounds are synthesized by vetted US manufacturing partners operating in cGMP-compliant facilities. Every batch is independently screened for purity, toxicity, and heavy metals before release.
Every batch undergoes independent analysis via HPLC and mass spectrometry. Results are documented in a Certificate of Analysis published on our site.
Orders ship same-day from our US facility with full tracking. Temperature-sensitive compounds are packed with cold-chain materials to preserve stability in transit.
Our Quality Commitment
We employ the same analytical methods used by pharmaceutical research organizations to ensure every compound meets the highest standard of quality and documentation.
HPLC Testing
High-performance liquid chromatography confirms compound identity and purity to 99%+.
Mass Spectrometry
MS analysis verifies molecular weight and structural integrity of every synthesized compound.
Published COAs
Full Certificates of Analysis are available for every batch, documenting purity data and testing methodology.
Toxicity & Heavy Metals
Every batch is screened for residual solvents, endotoxins, and heavy metals in addition to purity verification.
