About SupplyPeptides

About SupplyPeptides — a UK specialist, not a peptide marketplace

“For research purposes only. Not for human consumption. Every compound independently verified.”

SupplyPeptides exists for one reason: to give laboratories a peptide supplier they never have to second-guess. Every compound we stock is sourced, verified independently, and held to a standard deliberately stricter than the industry asks for.

Uncompromising Purity

Each batch passes independent analysis before it ships. Certificates of Analysis for current UK stock are listed in our COA library.

Precision at Every Step

Storage, handling, and packaging are controlled to match the rigour a research bench expects.

Researchers First

Not a marketplace — a specialist supply line for people who need reliable compound sourcing.

UK Warehouse, Fast Dispatch

Order before midday UK time and it typically leaves the same business day via Royal Mail 24.

The SupplyPeptides Standard

What we actually check, every batch

Every lot is HPLC-tested by an accredited third-party lab before it's listed for sale — not after a customer complains. Certificates are published online in our COA library.

01

HPLC purity assay

Identity and concentration confirmed by high-performance liquid chromatography to ≥99% purity.

02

LC-MS identity

Mass spectrometry verifies the compound matches exactly what the label states.

03

Physical QC

Lyophilisation quality and vial integrity checked before a lot is listed for sale.

Why we exist

Built for UK research supply

UK labs sourcing overseas were routinely getting inconsistent purity, missing documentation, and customs-delayed shipping. We built a UK-warehoused alternative — verified before listing, documented per lot, and dispatched same-day from UK stock.

Who this is for

University and private laboratories, contract researchers, and qualified individuals conducting in-vitro or analytical work under a research-use-only framework. We do not market, describe, or imply human or animal use anywhere on this site.
