Our Quality Commitment

Quality Standards

US Based

USA-Based Company

Sourcing, quality control and account support run from our US operations.

Documented Process

Qualified Manufacturing Partners

Every peptide is produced by vetted manufacturing partners operating documented quality procedures.

ISO 17025 Labs

Third-Party Identity Testing

Every batch is 10x tested at independent ISO 17025 accredited laboratories: purity (HPLC), net peptide content, identity, fentanyl screen, HPLC conformity, heavy metals (ICP-MS), sterility (PCR), endotoxin, solubility, and closure integrity.

99%+ Purity

99%+ Purity Standard

A batch that does not meet the 99%+ release standard does not ship.

Our Quality Process

01

Raw Material Verification

Our manufacturing partners test all raw materials for identity and purity before synthesis begins, verifying amino acid purity, solvent quality, and reagent specifications.

02

Peptide Synthesis

Partner facilities run solid-phase peptide synthesis (SPPS) in controlled cleanroom environments, following validated protocols with real-time monitoring.

03

Purification

Reverse-phase HPLC purification at our partners' production facilities, with multiple passes when necessary.

04

Independent Identity & Content Testing

Independent ISO 17025 accredited laboratories run the 10-assay panel on every batch we source.

05

Documentation

Full Certificate of Analysis generated with all test results. Batch records maintained for complete traceability.

06

Packaging & Storage

Partner facilities seal lyophilized peptides in sterile vials under nitrogen. Climate-controlled storage until shipment.

A Certificate of Analysis for every batch.
