Cold-Chain 3PL for Peptide Inventory: What to Ask a Fulfillment Partner
2026-05-08 · 5 min read
Fulfillment errors on research inventory are rarely about speed. They are about lots getting mixed and temperatures going unlogged.
Lot segregation
Ask how lots are separated in the pick location. If two lots of one SKU share a bin, the COA you send a customer is a guess.
Temperature logging
Frozen and refrigerated zones should be logged continuously, with excursion alarms. Ask to see a week of logs, not a specification sheet.
Dispatch cutoffs
A same-day cutoff only helps if it is real. Ours is 2PM PT for domestic orders, and tracking is emailed at label creation.
Ordering, minimums, and pricing
Every SKU is priced per vial and sold in sealed ten-vial kits with a one-kit minimum. Volume tiers: 1 kit at list, 2 kits at 5% off, 3 kits at 7% off, 5 kits at 12% off, and 10 kits at 20% off. Domestic orders received by 2PM PT dispatch the same business day, and freight is free above $2,500.
All compounds are sold as chemical reagents for laboratory research use only — not for human or veterinary use.
Frequently asked
- What is the minimum order?
- One ten-vial kit of any in-stock SKU. Mix compounds freely to reach a volume tier.
- Do orders include a certificate of analysis?
- Yes — lot-specific, with third-party HPLC purity and mass-spec identity.
