Pure PepLab
Testing starts November Analytical testing RUO only Results around 7 working days after Friday collection

Know purity and identity.
Priced in GBP for UK sellers.

Default panel is HPLC + LC-MS — chromatographic purity plus intact-mass identity support. Account-linked CoAs, public verify by report code, and a trade path for volume sellers. Research characterisation of materials you submit — not clinical grade, not for human use.

Testing starts in November

Order Pure Pep Lab testing

Create a lab account and order HPLC + LC-MS or HPLC purity testing directly, ahead of the November start. For professional and business research customers (18+) only — not a consumer service. Research characterisation (RUO) only.

Currently testing only: GLP-RT BPC-157 GHK-Cu — not a full peptide catalogue.

Intro pricing: £300 for the first 5 HPLC + LC-MS samples per signed-in account, then £349. HPLC purity-only £249. Trade rates on enquiry.

Not ready to order yet? Join the November waitlist to register interest — it opens your email to hello@purepeplab.co.uk with a short prompt (name, company, peptides from the three above, approximate volume).

List price

£349 per sample for HPLC + LC-MS after intro. Same panel, same turnaround aim.

What you get (plain English)

Purity — how clean the main peak looks under HPLC.
Identity — whether the mass is consistent with the named peptide.

Purity-only HPLC

Available to order · £249. Purity alone does not confirm identity. Most sellers should start with HPLC + LC-MS.

Not the default panel — purity alone does not confirm identity. Order HPLC purity only (£249).

What HPLC + LC-MS means on your certificate

One sample · one peptide · dual result panels. No ISO/UKAS accreditation claims on this site.

HPLC purity

Chromatographic main-peak area % under HPLC-UV/PDA. Shows relative purity of the submitted material — not net content or potency.

LC-MS identity

Intact-mass identity support. Report wording: “Consistent with {peptide}” when mass aligns with the named compound on the job.

Running regular batch checks? Contact us with your expected volumes and we’ll get back with a rate — no published tier card on this page.

Intro vs trade: Intro £300 is for the first 5 HPLC + LC-MS samples per signed-in account. Trade is a separate conversation for ongoing seller volume.

Built for repeatable evidence — not a race to the bottom.

GBP-priced combo default, portal status, branded CoA, and public verify — for sellers who need batch checks they can stand behind.

How it works

01

Create lab account & order

Register a lab account (professional / business research customers, 18+) and order HPLC + LC-MS or HPLC purity testing. Order testing.

02

Complete submission

Each sample tested gets its own submission code (PPS-XXXXXX), allocated automatically once your order is placed and payment is confirmed. It appears in My Account → Lab Testing, where you complete the submission details. We use it to track your sample and print it on your sample list; you do not need to write it on the vial.

03

Name vial & post

Make sure each vial is clearly named so it matches your sample list, put the printed sample list in the parcel, and post it to Pure Pep Lab, Cambridge. We recommend a tracked service; postage is at your cost and the sample is at your risk until we sign for it. Samples must reach Pure Pep Lab by Wednesday to join that week's Friday courier collection to the testing laboratory. How to submit a sample.

04

Report in account

Status updates, then download your PDF / CoA when ready. Results aim for around 7 working days after the Friday collection that includes your sample.

Weekly schedule: samples must reach Pure Pep Lab in Cambridge by Wednesday to join that week's Friday courier collection to the testing laboratory. Samples arriving after Wednesday go in the following week's Friday collection. The first weekly collection is in November.
