How we test Verify a batch How to judge a supplier
Eira London supplies the KPV peptide in the UK as a 10 mg vial of lyophilised research peptide, with an independent HPLC certificate for every batch and tracked UK delivery.
What the KPV peptide is
KPV is the tripeptide Lys-Pro-Val, the C-terminal fragment of α-MSH. Three amino acids; molecular weight 342.43 g/mol; molecular formula C16H30N4O4. It belongs to our Tripeptides & Blends range with GHK-Cu and GLOW.
How each batch is documented
Each KPV batch is tested by an independent laboratory using HPLC. The current batch’s certificate is shown on this page: purity, lot number, labelled and measured amount, and test date. Every published KPV batch, each with its PDF, is listed on the KPV certificate of analysis page, and any lot can be checked in the COA lookup. How we test.

Eira vs the rest
The peptide market has a trust problem. We don’t.
Independent reviews find roughly 40% of peptide sellers raise at least one major red flag — missing COAs, fabricated purity numbers, vanishing support. Here’s how we compare on the things that actually protect you.

Common Questions
Everything researchers ask before ordering.
What is KPV?
KPV is a tripeptide (α-MSH C-terminal fragment) with the sequence Lys-Pro-Val (3 amino acids). Molecular weight: 342.43 g/mol.
What purity is the current KPV batch?
99.74% purity by third-party HPLC on lot PH-kv101123, tested 20 Apr 2026. Labelled 10 mg; measured 11.34 mg. The certificate of analysis is on this page.
How fast does this ship?
Orders ship by tracked UK courier — typically 2–3 working days, with a next-day delivery option at checkout.
What's included with each vial?
Every order ships with the lyophilised vial, a tamper-evident seal, and a packing slip referencing the batch ID. The matching certificate of analysis is on this page and available on request.
How is purity verified?
Every batch is tested by an independent third-party lab using HPLC, and the batch-specific certificate of analysis reports the measured purity — we won't list a compound that falls below our threshold.
How should this be stored?
Lyophilised, store at -20°C in a dry, dark place. Once reconstituted, keep refrigerated at 2–8°C. Full storage and handling notes are listed on this page.
What payment methods do you accept?
Secure card payment (Visa, Mastercard, Amex) alongside PayPal and Google Pay — never crypto-only. Every order is processed over an encrypted checkout.
What's your return policy?
Unopened, intact items can be returned — just contact us with your order reference. For any quality concern we'll always make it right. Opened vials can't be returned, for integrity reasons.
Do you ship internationally?
We currently dispatch within the UK. For international research enquiries, contact our team and we'll advise on what's possible.
Are these products for human use?
No. Every Eira compound is supplied strictly for laboratory research use only — not for human or animal consumption, medical use, or self-administration.
