Peptide bundles — bulk vial packs

Bundles are bulk packs of the same compound, or of a small number of compounds ordered together, intended for longer-running work where consistency between vials matters. Wherever stock allows we fill a bundle from a single lot, so an entire study can run against one batch of material rather than several.

This matters in practice: switching lots part-way through a series introduces a variable that is difficult to unpick afterwards. Ordering a ten-vial bundle up front removes that problem and reduces the per-vial cost at the same time.

Every vial is supplied lyophilised, sealed and labelled with its lot number, and each lot is HPLC-verified to 99%+ purity before release. Bundles are stored at −20°C and dispatched together in insulated packaging with a cold pack from our UK facility, normally within 48 hours of a cleared order.

Bundle contents are supplied strictly for in-vitro laboratory research. They are not medicines, are not licensed for human or veterinary use, and we provide no administration guidance of any kind.

Same-lot filling and traceability

Where a bundle is filled from one lot, every vial in the box carries the same lot number and is covered by a single certificate of analysis.

If current stock cannot cover a bundle from one lot we will tell you before dispatch rather than substituting silently.

Frequently asked questions

Will every vial in a bundle come from the same batch?
Wherever stock allows, yes — and we will contact you before dispatch if a bundle has to be filled across more than one lot.
How should unopened vials be stored?
Sealed lyophilised vials are stable stored at −20°C, away from light and moisture. Our storage guide covers the handling routine we use in the lab.
Do bundles qualify for auto-ship?
Yes. Bundles can be placed on monthly auto-ship at checkout with a 10% saving, and paused or cancelled from your account at any time.
