Why Research Labs Switch Peptide Suppliers
2026-04-04 · 5 min read
Nobody switches suppliers over price. They switch over documentation, consistency, and communication.
The five failures
Missing or generic COAs, lot-to-lot variation, warm arrivals, silent stockouts, and minimums that force overbuying.
What prevents them
Lot-specific third-party assay, batch production records, insulated same-day dispatch, published stock levels, and a one-kit floor.
Testing a new supplier cheaply
Order one kit, assay it, and read the paperwork before moving any real volume.
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.
