Retatrutide (LY3437943) is an investigational triple agonist at the GIP, GLP-1 and glucagon receptors. It is not approved as a medicine by any regulator in the world, and it is still in clinical trials. Supplied for laboratory research use only — read the whole page before you decide.
This is a drug in development, not a supplement. Here is the honest state of the evidence.
A single peptide designed to act at three receptors: GIP, GLP-1 and glucagon. That much is well documented.
Phase 2 obesity results were published in the New England Journal of Medicine in 2023. Phase 3 is still running. Nothing is finished.
No regulator anywhere — MHRA, EMA, FDA — has authorised retatrutide for any use. It is not a licensed medicine.
The published trials administered retatrutide subcutaneously. This product is a capsule. Peptides taken by mouth are largely broken down in the gut.
Trial participants reported nausea, vomiting, diarrhoea and constipation, and dose escalation was managed by clinicians throughout.
Identity and purity, per batch, by a laboratory we do not own. We verify what is in the capsule — nothing about what it does.
What is in the bottle, and what is on the certificate.
Retatrutide (LY3437943) is designed to act at all three receptors.
Supplied as a capsule. The clinical trials used subcutaneous injection; oral bioavailability of peptides is generally very low.
We do not publish a human dosing protocol for this compound.
Each batch is assayed by Janoshik Analytical, an independent laboratory. The Certificate of Analysis for your batch is available on request.
This product is supplied for laboratory research use only. We do not provide dosing instructions or titration schedules for human use. If you are seeking treatment for obesity or diabetes, speak to a doctor — there are licensed medicines for that, and this is not one of them.

We don't have customer reviews to show you yet, and we're not going to invent any. Here is what we can actually put in front of you instead.
Batches go to Janoshik Analytical, an independent testing laboratory. We don't choose the result.
A certificate from a batch made two years ago says nothing about the pack in your hand.
Email it to us with the product name and we'll send the Certificate of Analysis for that batch.

No. Not by the MHRA, not by the EMA, not by the FDA, not by anyone. Phase 3 trials are still running. Anyone telling you otherwise is wrong.
This product is supplied for laboratory research use only. We do not publish dosing or titration guidance for human use.
A fair question, and we would rather you asked it than not. The published trials used subcutaneous injection. Peptides taken by mouth are largely degraded by digestive enzymes before absorption. We are not going to claim an oral capsule reproduces trial results.
No. Speak to a doctor. There are licensed weight-management medicines with approved safety profiles and clinical supervision. This is not one of them and we are not selling it as one.
Yes — identity and purity, per batch, by Janoshik Analytical. Email us the batch number from your pack and we will send that batch's Certificate of Analysis.
