Phase 2 trial - New England Journal of Medicine, 2023Triple-receptor research peptide
Retatrutide
An investigational peptide studied for how it acts on three receptor systems at once. Supplied for laboratory research only.
Your body already has a way of telling you you've had enough to eat. Retatrutide caught researchers' attention because it works on three of those signals at once, where the compounds you've heard of work on one or two. We supply it freeze-dried, for laboratory research only.

Research use onlyWhy this molecule is studied
Why researchers are studying it.
Here's the setup. When food arrives in your gut, your gut releases hormones that travel up and tell your brain to ease off. One of them is called GLP-1. That's the signal semaglutide - Ozempic - copies, and it's the reason that drug became a household name.
Retatrutide doesn't copy just that one. It works on three signals together: GLP-1, plus two more the papers call GIP and glucagon. Tirzepatide (Mounjaro) added the second one. Retatrutide adds the third. The whole question researchers are testing is whether pulling three levers at once does more than pulling one or two.
It comes from Eli Lilly, the papers call it LY3437943, and it has reached Phase 3 - the big final round of human trials that comes before any regulator decides whether to approve something. It hasn't been approved anywhere yet.
Everything here is about that published research and about which batch you're getting. It isn't a claim about what this vial will do.
The research
What the published studies found.
Average drop in liver fat after 24 weeks in a smaller fatty-liver sub-study, measured against each person's starting level.
Nature Medicine, 2024How much lower blood sugar (HbA1c, a three-month marker) ran in the higher-dose groups of the Phase 2 diabetes trial.
Phase 2 trial - Lancet, 2023Receptor systems the peptide acts on - GLP-1, GIP and glucagon - which is why it's studied as a 'triple agonist'.

Plain-language research labels.
Three signals, three different jobs. Here's what each one actually does - the science in the published papers, not a description of what this vial does.
GLP-1
The 'that's enough' signal. Your gut releases it when food shows up, and it does two things researchers care about: it tells your brain you're full, and it slows how fast your stomach empties. Ozempic works on this one, and only this one.
GIP
The other gut signal, firing after the same meal. Its job leans towards insulin - how the body handles the sugar and fat that just arrived. Mounjaro added this one on top of GLP-1, and that is what made it different from Ozempic.
Glucagon
The odd one out, and the reason Retatrutide exists at all. The first two signals are about intake. Glucagon is about spend: when the body needs energy and none is arriving from food, glucagon is the message that goes to the liver saying release some. It is the mirror image of insulin - insulin puts energy away, glucagon takes it back out. That third lever is the whole bet.

FAQ
Questions, answered plainly.
RETATRUTIDE is supplied as laboratory research material only. It is 21+ only, not for human consumption, and not for veterinary use.
Yes. The product page lists lot, identity, purity, appearance, release status, and storage notes for RETATRUTIDE.
Follow the label and matching COA paperwork. This page repeats 2-8 C storage guidance and light-protection notes before checkout.
Retatrutide is a lab-made peptide known in research as LY3437943, developed by Eli Lilly and now in Phase 3 human trials. Published studies describe it acting on three receptor systems at once - GLP-1, GIP, and glucagon - which is why researchers call it a triple agonist. The spec sheet lists it as a freeze-dried research reference with CAS 2381089-83-2 and a molecular weight of 4731.34 Da. Form Laboratories supplies it for laboratory research only, not for human use.
The current batch is lot RTD-2506, and that lot code is printed on the vial label. The matching lab report for RTD-2506 records identity, purity, appearance, and release status, with purity measured at 98.2% by HPLC. Those figures come from the batch paperwork, not from the published trial literature. Always check the vial against the RTD-2506 report before lab intake.
The spec sheet and COA both list storage at 2-8 C, protected from light. Retatrutide is supplied as a freeze-dried powder, so it stays in that form until a lab chooses to work with it. Storage conditions stay on the vial, the packing slip, and the COA paperwork for lot RTD-2506. This is handling context only, not a preparation or use instruction.
Add the size and quantity you want to your cart and check out. Instead of paying by card, you'll get an emailed invoice with our bank details - pay by bank transfer, quoting the reference. Once the payment clears we pack your order and send it, and you'll get a tracking email. A faster transfer (PayID or Osko) gets things moving sooner.
Every batch is tested by an independent lab. A purity test (HPLC) measures how much of the powder is the intended compound, an identity test confirms it's the right one, and it's screened for bacterial residue. The measured purity is printed on the lab report and tied to the batch number on your vial.
It ships from our base in Perth via Australia Post, in plain packaging with nothing identifying on the outside, once your payment has cleared. You'll get a tracking email, and the tracking link shows the delivery estimate for your address. On arrival, store it in the fridge at 2-8 C and keep it out of light.
Every compound carries a 30-day purity guarantee. If an independent lab re-tests the batch within 30 days and it comes back below the purity stated on its lab report, we refund the order in full - and you don't need to send the vial back.
No. It's supplied strictly as reference material for laboratory research - not a medicine, supplement, or food, and not for people or animals to take. The research described on this page is about the Retatrutide molecule in published studies, not about a Form Labs product.
