Why Moon Peptides
Quality you can verify, not just claims
We treat purity as a number you can check — every batch, every lot, documented and downloadable.
Assayed to ≥99%
Independent HPLC & MS analysis on every batch — each lot assayed to ≥99%. The readout above is a recent lot's measured result, not a marketing number.
A COA for every lot
Download the third-party certificate before you order — and the one matching the exact lot you receive.
US-based & US-shipped
Stocked, shipped, and supported from the US, with fast, tracked, US-only delivery.
Chain of custody
Built for research integrity
Batch traceability, tamper-evident packaging, and a documented chain of custody from lot to lab bench — so the certificate always matches the vial in your hand.
How we work
Documented quality, real support, fair pricing
Quality is not a slogan — it's the standard behind every decision, from catalog sourcing to final packaging.
Controlled sourcing & quality review
Catalog materials are sourced and handled through controlled procedures — clear lot records, documented handling steps, and ongoing review of supplier consistency.
Synthesis & purification standards
Peptide materials are produced using established synthesis and purification workflows. Purity and identity are documented specifications reviewed for every listing and lot — not assumptions.
Transparent documentation
Where available, we provide Certificates of Analysis and relevant lot information, so qualified customers can maintain accurate internal records and support traceability.
Real support & fair pricing
Our US-based team is available by email and through our contact page. Find a lower advertised price on comparable catalog material? Let us know — we'll review it and work to stay competitive.
