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.

What the research explores

GHRH-receptor pharmacology

Tesamorelin is a stabilised analogue of growth-hormone-releasing hormone (GHRH), studied as a GHRH-receptor agonist in endocrine-signalling research.

Somatotropic-axis models

In vitro and animal research examines GHRH analogues within growth-hormone-axis signalling models.

Analogue design

Tesamorelin is studied as a stabilised 44-amino-acid GHRH analogue in peptide-chemistry research.

Everything researchers ask before ordering.

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.
