What is retatrutide?
Retatrutide (research code LY3437943) is a synthetic peptide being developed by Eli Lilly as an experimental drug. The compound is referred to as a triple agonist: in research, it binds to the GLP-1, GIP, and glucagon receptors. Consequently, retatrutide is investigated in preclinical and clinical research into metabolic signaling pathways.
Status
Retatrutide has not been approved by any medicines authority (source verification 8 September 2026). Clinical trials are conducted under medical supervision using dedicated study material; their outcomes imply nothing regarding this vial. PEPTID8 does not supply any Lilly product, nor material from a clinical trial.
What you order
Lyophilized research material in vials with a nominal content of 20 mg or 30 mg. The number of milligrams describes the amount of material per vial and is not a recommendation for use. The lab report on this page indicates which report belongs to each variant, the strength tested, and how to verify it independently with the laboratory. If the tested strength deviates from the selected vial, this is explicitly stated.
Documentation
HPLC purity, identity (FTIR or mass spectrometry), and quantity are separate quality parameters. Verify in the report which sample and analyses have been reported, and record the variant and lot reference in your research records upon receipt.
Exclusively for in vitro research and laboratory use. Not for human or veterinary application.

Stap 1
Purity by HPLC
Liquid chromatography separates the sample; purity is the proportion represented by the main peak.
Stap 2
Identity by FTIR
FTIR compares the sample’s infrared spectrum with a reference spectrum to confirm identity.
Stap 3
Content by quantitative testing
A separate measurement determines how much substance is in the vial, where included in the report.

Calculation example: 20 mg lyophilisate in 2 ml bacteriostatic water = 10 mg/ml. 30 mg in 3 ml (one bottle of BAC water) = likewise 10 mg/ml. Allow the solvent to run down the inside glass wall and swirl gently, do not shake.

What is the difference between the 20 mg and the 30 mg vial?
Only the nominal amount of material per vial. The current price and the price per mg are listed for each strength. The number of milligrams is not usage advice.
Which lab report belongs to these vials?
In the lab report block on this page. There you can see which report corresponds to the selected variant, what strength it is, and how to verify it yourself with the lab. If the tested strength differs from the selected vial, this is explicitly stated.
How do I store retatrutide?
The unopened lyophilisate at −20 °C, dark and dry. After reconstitution at 2–8 °C; product-specific stability data for the solution are not published, so follow the timeframe of your validated lab protocol.
How much solvent do I use for reconstitution?
That depends on the concentration your protocol requires. Example: 20 mg in 2 ml or 30 mg in 3 ml gives 10 mg/ml; the peptide calculator converts other volumes.
Is retatrutide an approved medicine?
No. Retatrutide is under clinical investigation and has not been approved by any medicines authority. This product is research material for the laboratory, not a medicine.
Is retatrutide the same as semaglutide or tirzepatide?
No. Semaglutide targets the GLP-1 receptor and tirzepatide targets the GLP-1 and GIP receptors; in research, retatrutide additionally binds to the glucagon receptor. These are distinct compounds that are not interchangeable.
How is it shipped and does it need to be refrigerated?
The lyophilisate is shipped dry in neutral packaging without mention of the contents, from the Netherlands via PostNL (NL next business day, EU 1–4 business days). Place the vial at the correct storage temperature immediately upon receipt.
What is in the package?
You receive one glass vial with lyophilized powder, nothing else. Bacteriostatic water and other laboratory supplies are not included and can be ordered separately in Lab Accessories.
How do I place an order?
Place products in your shopping cart and complete the order at checkout. There you enter your details, choose a payment method, and confirm the three mandatory declarations. You will immediately receive a confirmation by email with the overview and, in case of payment by bank transfer, the payment details.
When will my order be shipped?
Ordered and paid before 22:00 on business days: shipped the same day. In the case of a bank transfer, the time your payment is received applies. After 22:00, on weekends, or on public holidays, your order will be dispatched on the next business day. If it is busy, this will be stated at the top of the site with the new shipping date.
