ISO-7 cleanroom synthesis.
cGMP-aligned US manufacturing.
Every Bench Grade reference standard is synthesized in a US ISO-7 certified cleanroom, manufactured at a US facility operating under cGMP-aligned procedures, and stored under 24-hour CCTV cold-chain with time-locked chain-of-custody. Every lot ships with an independently-issued Certificate of Analysis.
Strategic raw-material sourcing
Synthesis inputs are sourced from a curated network of US domestic and international suppliers, each pre-qualified for purity, chemical fidelity, and supply continuity. Every inbound batch is qualified at the synthesis facility before it enters the production line — incoming material that fails identity, purity, or contaminant thresholds is rejected.
Supplier qualification records and incoming-material test results are retained as part of the per-lot manufacturing record. Available for review under NDA for institutional and wholesale buyers.
ISO-7 cleanroom synthesis, cGMP-aligned manufacturing
Synthesis takes place at our US-based laboratory in an ISO 14644-1 Class 7 (ISO-7) certified cleanroom. ISO-7 specifies airborne particulate limits, air-change rates, and gowning protocols suitable for sterile and near-sterile compounding work.
Primary manufacturing takes place at a US-based facility that operates under cGMP-aligned (current Good Manufacturing Practice) procedures including:
- Multiple ISO cleanroom suites with continuous environmental monitoring (particulate, viable, temperature, humidity)
- On-site analytical labs for in-process release testing
- Equipment qualification (IQ/OQ/PQ) on every production line
- Batch-record documentation linked to lot identifier on every vial label
- Deviation, CAPA, and change-control procedures
- Operator training records reviewed at hire and annually
Note: our products are research-grade analytical reference standards sold for laboratory research use only and are not FDA-approved drugs. See our Compliance statement for the full research-use-only certification.
Cold-chain time-lock chain-of-custody
Finished lyophilized vials are stored under 24-hour CCTV-monitored cold chain at controlled temperature. The cold-storage rooms operate under time-locked access — every entry and material movement is recorded and added to the chain-of-custody record for the affected lots.
Outbound shipments use insulated packaging and ice-pack temperature control where required by the compound’s stability profile. Standard domestic transit times keep lyophilized peptides well within their stability window; expedited 2-Day, Overnight, and Priority options are available at checkout for time-sensitive workflows.
Independent third-party per-lot analysis
Every production lot is sent to Chromate.org, an independent US-based analytical laboratory, for verification of:
- HPLC purity — target ≥99.0% by integrated peak area; lots below threshold are re-purified or rejected
- Mass-spec identity — MS/MS or LC-MS confirmation of compound identity against the expected molecular ion
- Heavy-metal screening — ICP-MS panel screening for trace heavy-metal contaminants
A QR-traceable Certificate of Analysis ships on every vial, linking the vial label to the lot record and the third-party-issued analytical results. Learn how to read a Certificate of Analysis, or read what “made in the USA” actually means for a peptide.
Why we don’t publish them
Bench Grade Peptides operates under exclusivity arrangements with our US synthesis and manufacturing partners. The names of those partners are confidential under those arrangements and are not publicly disclosed.
Institutional buyers, prescribing providers, and wholesale clinic accounts may request additional supply-chain documentation including facility names and ISO certification references under a mutual non-disclosure agreement. Email compliance@benchgradepeptides.com with your account information to start the NDA process.
