The Mode Peptides Standard

≥99% Purity Guaranteed

Each lot undergoes third-party analytical testing, including HPLC and mass spectrometry, to verify identity and purity. Every batch is supported by documented test results for research transparency.

Same-Day Fulfillment

Weekday orders placed before the daily cutoff are processed and shipped the same business day, with tracking provided so you can follow your order from dispatch to delivery.

COA With Every Batch

Every lot is accompanied by a Certificate of Analysis (COA) documenting key quality and analytical results. COAs are published to make batch-level information easy to review and verify.

Scan-to-Verify Vials

Each vial features a batch-specific QR code that connects directly to its corresponding certificate and testing documentation. Verify the lot you're receiving—not just the label.
