Who this is for

For organisations sourcing research-grade peptides at sustained volume, with documented analytical needs and an institutional address. We review every application before issuing pricing.
Labs
Research laboratories

Academic, government, and private labs running in vitro studies and analytical reference work.

CRO / Biotech
CROs & biotech teams

Contract research organisations and biotech teams needing documented reference standards across multi-year studies.

Distribution
Qualified distributors

Licensed distributors supplying research laboratories and analytical end users in regulated jurisdictions.

What partners get

Wholesale isn't a discount badge. It's a different operational tier: reserved stock, sustained pricing, and a direct line to the chemists running your batches.

Lot-locked supply

Reserve a specific lot for the length of your study. We hold it and you call it forward, with no batch drift across timepoints.

Tiered pricing

Volume pricing that steps down at 50 / 100 / 250 / 500 vials, with custom quotes for repeat orders.

Documentation

Audit-ready paperwork for internal QA or publication: COA, chromatograms, and net content per lot.

Account support

A direct line to a research account manager for documentation and custom batches, not a ticket queue.

Built to a documented standard

Typical values across the catalog. Per-lot detail accompanies every quote and is matched to the lot ID on the vial.

Common questions

What is the minimum order quantity?+
Standard catalog MOQ is 50 vials per compound. Volume pricing applies at 50, 100, 250, and 500 vials. Custom runs and specialty blends carry separate MOQs your account manager will quote directly.
Is a Certificate of Analysis included with bulk orders?+
Yes. Every lot is independently tested by HPLC/MS through an ISO/IEC 17025-accredited laboratory. The per-lot COA documenting identity, purity, and net content is provided for your specific lot and is searchable in our public COA library.
Do you offer white-label or private-label peptides?+
Yes. Submit your label artwork, assign your own internal lot codes, and specify cap colors. MOQs apply by configuration; lead time is typically 7–14 business days from artwork approval.
What are your terms and lead times?+
In-stock catalog items ship in 1–2 business days. Custom runs fulfill in 7–10 business days. Net-30 terms are available for verified institutional accounts with approved credit.
Can I reserve a specific lot for my study?+
Yes. Verified partners can lot-lock a batch for the duration of a study. We hold the reserved stock and you call it forward as needed, keeping a single lot across all your timepoints with no batch drift.
Who qualifies for a wholesale peptide account?+
