What is Retatrutide?
Retatrutide is catalogued by Amino Fuel Labs as a triple incretin agonist and is supplied as lyophilized powder (10mg) for controlled laboratory work. Reported identity data for this compound include molecular formula C₂₂₁H₃₄₂N₄₆O₆₈, molecular weight 4731.33 g/mol, sequence Y-Aib-QGTFTSDYSI-αMeLeu-LDK-Lys(AEEA-γGlu-C20 diacid)-AQ-Aib-AFIEYLLEGGPSSGAPPPS-NH₂. It is studied for activity at GLP-1, GIP and glucagon receptors in preclinical studies and clinical trials; published findings describe the studied compound and do not establish the safety or efficacy of this supplier's material. Material is released lot by lot: each batch is assayed by an independent laboratory using reversed-phase HPLC for purity and mass spectrometry for identity, and the resulting Certificate of Analysis is matched to the lot number printed on the vial you receive. Vials are stored at -80°c (long-term); -20°c (short-term); sealed, away from moisture and light, under nitrogen and are shipped from our United States facility with the accompanying lot documentation. Amino Fuel Labs publishes no administration protocol for Retatrutide; it is distributed strictly for laboratory research.
Retatrutide (LY3437943) is a research peptide studied at the GLP-1, GIP and glucagon receptors. Amino Fuel Labs lists 10mg, 30mg and 50mg lyophilized vials for laboratory research. Compare current prices in the table above, then select a vial size to review its availability, lot number and linked Certificate of Analysis. Read the HPLC purity result for that specific lot; a result for one strength does not establish purity for the others. Vial size is the quantity of material supplied in each vial.
How Retatrutide works
Retatrutide is a single 39-amino-acid synthetic peptide engineered to activate three metabolic receptors at once: GLP-1 (glucagon-like peptide-1), GIP (glucose-dependent insulinotropic polypeptide), and the glucagon receptor. GLP-1 receptor signaling is studied for its role in gastric-emptying and metabolic pathway research. GIP activation amplifies insulin secretion and modulates lipid storage. Glucagon receptor signaling is examined in lipolysis and energy-expenditure pathway work, an arm that dual-receptor compounds such as Tirzepatide do not engage. Combining all three signals in one peptide is why Retatrutide is a frequent reference compound in preclinical metabolic pathway research within a laboratory research context.
Retatrutide research summary
Retatrutide (LY3437943) has been described in published preclinical pharmacology and in clinical trials as a triple GLP-1, GIP and glucagon receptor agonist. Its receptor profile differs from dual GLP-1/GIP agonists such as Tirzepatide, which do not engage the glucagon receptor, and from GLP-1-only compounds. Published clinical results describe the studied compound under trial conditions; they do not verify the identity, purity or performance of material from any supplier, including this one. For laboratory work, rely on the lot-specific Certificate of Analysis for the vial you receive.

Testing method
Reversed-phase HPLC with mass-spectrometry identity confirmation
Every lot of Retatrutide we list is supplied with a lot-matched Certificate of Analysis. Identity is confirmed by mass spectrometry and purity is measured by reversed-phase HPLC, with both results reported for the specific lot printed on the vial label. The certificate travels with the order, so the documentation can be reconciled against the material on receipt. Purity is a lot-specific value: read the figure on the certificate that matches your vial rather than treating it as a fixed product attribute. Supplied for laboratory research use only.

Retatrutide customer reviews
4.96 out of 5 from 130 approved customer reviews.
This is the cleanest Retatrutide I have found, period. The 10mg vials are convenient and everything has been consistent across my orders. Worth the money.
Started at 1mg weekly and worked up slowly from there. Appetite noise basically disappeared by week two and my energy stayed steady, no afternoon crash. Mixed clean with 1mL bac water and dosing on the insulin syringe was simple to track.
Three months in now and holding at 4mg weekly, which is working amazing for me. Titrated up slow from 1mg and never felt rough doing it. The 30mg vial lasts a while and mixing has been consistent every time. Reordering is quick and it shows up fast.
On my third Retatrutide order and honestly it just works. Down 25lbs in 3 months, appetite is quiet, energy is steady. Order got stuck in a Memphis hub for two days and someone from their team emailed me the tracking update before I even thought to check. Little things like that keep me coming back.
I keep a close eye on what my patients ask about, so I tried this one myself first. Conservative start, clean tolerability, appetite suppression exactly where I expected it. Consistency has been solid across two orders.
Retatrutide FAQ
What is Retatrutide studied for?
Retatrutide is studied for activity at GLP-1, GIP and glucagon receptors. Published research includes preclinical studies and clinical trials. The material listed here is supplied for laboratory research only; published clinical findings do not establish the safety or efficacy of this supplier's material.
Does Retatrutide include a Certificate of Analysis?
Yes. Each Retatrutide lot ships with a batch-specific third-party Certificate of Analysis reporting lot-specific (10mg lot 99.52%, 30mg lot 99.54%, 50mg lot 99.10%; other strengths per their own certificate) purity by reversed-phase HPLC with mass-spectrometry identity confirmation. The COA linked on this page matches the lot number printed on the vial.
What form does Retatrutide arrive in and how is it stored?
Retatrutide is supplied as lyophilized powder (10mg) in a sealed vial with its lot documentation. Store at -80°C (long-term); -20°C (short-term); sealed, away from moisture and light, under nitrogen, protect the vial from light and avoid repeated freeze–thaw cycles.
Does HPLC purity tell me the net peptide content?
No. HPLC area-percent purity and net peptide content are different measurements. Review the report for each value rather than treating them as interchangeable. Read about peptide purity versus net content.
Is Retatrutide a peptide?
Yes. Retatrutide (LY3437943) is a single 39-amino-acid synthetic peptide studied as a triple agonist of the GLP-1, GIP, and glucagon receptors. It is supplied as a lyophilized research material for laboratory use only.
How does Retatrutide compare to Tirzepatide?
Tirzepatide is a dual GLP-1 / GIP agonist. Retatrutide is described as a triple GLP-1 / GIP / glucagon receptor agonist, so its receptor profile adds glucagon-receptor activity that Tirzepatide does not have. Results from separate trials are not directly comparable, and published findings do not describe this supplier’s material.
How much does Retatrutide cost?
Retatrutide is listed in these sizes: 10mg at $105.00 per vial ($10.50 per mg); 30mg at $290.00 per vial ($9.67 per mg); 50mg at $395.00 per vial ($7.90 per mg). Check the strength selector for availability and the linked Certificate of Analysis for the selected material. Shipping is shown at checkout.
Where can I buy Retatrutide in the USA?
Amino Fuel Labs ships Retatrutide from a USA fulfillment center with same-day dispatch before 2:00 PM ET and 2–4 business day standard delivery — no overseas relay and no customs hold.
How do I verify a Retatrutide vendor before buying?
Match the Certificate of Analysis to the exact lot number on your vial, then check the test date, the report identifier, the issuing laboratory and the actual measured results, such as the HPLC purity figure and mass-spectrometry identity data. Where the issuing laboratory offers verification, confirm the original report directly with that laboratory. Shipping origin does not establish identity or purity.
Is Retatrutide 10mg or 30mg the better value?
Retatrutide 10mg is $105.00 per vial ($10.50 per mg), and 30mg is $290.00 per vial ($9.67 per mg). Compare all listed strengths in the pricing table above; availability and shipping are shown before checkout.
What is Retatrutide (LY3437943)?
Retatrutide, also referenced by its development code LY3437943, is a 39-amino-acid synthetic peptide studied in vitro as a triple agonist at the GLP-1, GIP and glucagon receptors. Amino Fuel Labs supplies it as a lyophilized powder in 10 mg, 30 mg and 50 mg vials with a lot-matched Certificate of Analysis, strictly for laboratory research use.
How does Retatrutide work in research models?
Published in-vitro work describes Retatrutide binding three receptors at once. GLP-1 receptor signaling is studied in gastric-emptying and insulin-response pathways, GIP signaling in insulin secretion and lipid handling, and glucagon-receptor signaling in lipolysis and energy-expenditure pathways. The glucagon arm is what separates it from dual agonists such as Tirzepatide in receptor-pharmacology studies.
How much bacteriostatic water is used for a 10mg Retatrutide vial?
For laboratory handling reference only: adding 2 mL of bacteriostatic water to a 10 mg vial gives a 5 mg/mL working solution, and 1 mL gives 10 mg/mL. Add the diluent slowly down the vial wall and swirl — never shake or vortex. Full volume-per-mg tables are published at /peptide-info.
Is Retatrutide a GLP-1, or is it a "GLP-3" peptide?
Retatrutide does act at the GLP-1 receptor, but it is not a GLP-1-only compound. It is documented as a triple GLP-1 / GIP / glucagon receptor agonist. The informal label "GLP-3" circulating online is not an established receptor class — there is no glucagon-like peptide-3 receptor; the term is shorthand some writers use for the three-receptor mechanism.
How should Retatrutide be stored before and after reconstitution?
Follow the storage and handling instructions documented for the exact lot and the validated conditions for your laboratory work. Reconstituted stability depends on preparation and storage conditions. Contact us if the relevant lot documentation is unavailable.
