MT1
How we test Verify a batch How to judge a supplier
Eira London supplies the MT1 peptide in the UK as a 10 mg vial of lyophilised research peptide, with tracked UK delivery.
What the MT1 peptide is
MT1 is a synthetic tridecapeptide analogue of α-MSH with the sequence Ac-Ser-Tyr-Ser-Nle-Glu-His-D-Phe-Arg-Trp-Gly-Lys-Pro-Val-NH2. It is N-terminally acetylated and C-terminally amidated, with norleucine (Nle) and D-phenylalanine (D-Phe) in its sequence. Molecular weight 1,646.87 g/mol; molecular formula C78H111N21O19; CAS 75921-69-6. It belongs to our Melanocortin Analogues range.

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.
Comparison reflects common practices across the research-peptide market; individual sellers vary.

What the research explores
Melanocortin-receptor pharmacology
MT1 is an analogue of α-melanocyte-stimulating hormone (α-MSH), studied as a melanocortin-receptor agonist in receptor-pharmacology research.
Melanin-synthesis models
In vitro research examines α-MSH analogues within melanin-synthesis models.
Analogue stability
As an Nle⁴, D-Phe⁷-modified analogue, MT1 is studied for its stability relative to native α-MSH in peptide-chemistry research.

Everything researchers ask before ordering.
What is MT1?
MT1 is a α-MSH analogue (tridecapeptide) with the sequence Ac-Ser-Tyr-Ser-Nle-Glu-His-D-Phe-Arg-Trp-Gly-Lys-Pro-Val-NH2. Molecular weight: 1646.87 g/mol. CAS 75921-69-6.
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.
