What this peptide is for

Triple agonist peptide.

Retatrutide (CAS 2381089-83-2) combines GIP, GLP-1, and glucagon receptor activation in a single sequence. Phase 2 clinical trials have reported substantial reductions in body weight and improvements in metabolic markers. Formula C223H341N57O64S, MW 4858.60 g/mol. Strict clinical guidance required.

How to use

Simple, deliberate steps — not a protocol.

These are practical handling notes. Dosing decisions stay between you and your clinician.

  1. 1

    Reconstitute under clinical guidance — dose titration from a low starting dose is essential

  2. 2

    Administer subcutaneously as directed; follow the prescribed dose escalation schedule

  3. 3

    Refrigerate reconstituted vial; use within 28 days

Third-party lab report
Independent batch testing

Every batch is analysed by an independent ISO/IEC 17025-accredited laboratory. Identity, purity, and mass-spec results are published on the product page before you buy.

Quality documentation
ISO/IEC 17025-accredited lab testing

Every batch is verified by an ISO/IEC 17025-accredited laboratory before release. Identity, purity, and documentation travel with the product — not behind a form.

Storage & shipping
Cold-chain integrity

Sensitive peptides ship in insulated cold-chain packaging with gel packs sized for a 48-hour transit window, tracked door to door.

Questions, answered plainly

Everything worth asking before you order.

Shipping, storage, quality, and when to speak to a clinician — without the runaround.

What proof of quality comes with my order?

Every batch ships with a batch code printed on the vial. The matching third-party certificate of analysis — identity, HPLC purity, and mass-spec results — is linked on the product page and also available from your order page after purchase.

Should I speak to a clinician before using a peptide?

We recommend it — especially if you are pregnant, nursing, managing a medical condition, or combining peptides with prescribed medication. Our product pages are educational. They are not medical advice and they do not replace a conversation with a qualified practitioner.

When will my order ship and arrive?

Orders placed before 14:00 CET Monday–Friday ship the same business day from our European fulfilment centre in The Hague, Netherlands. Standard tracked EU delivery arrives in 2–4 business days; express options are available at checkout.
