No regulator has approved retatrutide for treatment: the compound is still in clinical trials and is sold as a research material (research use only) for laboratory use, not as a product for self-administration. Below: how to check a batch against its COA, where to see the current price, a pre-order checklist, and a note on product status and supplier transparency.
What retatrutide is and why its status matters
Retatrutide activates the GIP, GLP-1 and glucagon receptors at the same time, a triple agonist that engages three targets instead of one, which is exactly the direction part of metabolic-hormone research is currently moving in.
Retatrutide has no consumer brand. The reason is simple: it is still in clinical trials and has not been registered as a medicine by any regulator (FDA, EMA, or otherwise). By comparison, semaglutide has already reached the market under the brands Ozempic and Rybelsus (Novo Nordisk), and tirzepatide under the brand Mounjaro (Eli Lilly). Longeva does not sell any of these branded drugs and has no affiliation with them; they are mentioned here only to explain the difference in regulatory status. Longeva sells retatrutide as a research reagent intended for laboratory work.
Triple agonist: how it is described in the literature
In a Phase 2 trial in patients with obesity, retatrutide was tested specifically as a GIP/GLP-1/glucagon triple agonist. The mechanism is described in detail in the publication by Jastreboff and co-authors in the New England Journal of Medicine[^1]. We deliberately do not cite weight-loss or efficacy figures here: this article is about how to buy a research material, not promotional copy about outcomes. The clinical picture is best read directly from the primary source, not a marketing retelling of it.
Buying retatrutide from Longeva: what's included
Longeva offers retatrutide as a research-grade material: a lyophilized peptide in a vial, intended for laboratory use. We do not sell a ready-to-use injector pen or self-administration instructions, and that is exactly what separates a research product from a registered medicine.
For the full product card, current stock, and specifications, see the retatrutide product page.
Available form and packaging
At the time of publication, the catalog carries a 5 mg lyophilized vial of retatrutide. Available sizes and dosages can change, so always check the product page, not this article, for the current lineup. There are no reconstitution or self-injection instructions here: that information is covered separately, in an educational format, in the retatrutide documentation.
Transparent pricing: how much retatrutide costs
The current vial price and stock availability at Longeva are always shown live on the product page, so verify the amount there before ordering: retatrutide, product page. Price differences between suppliers are usually tied to packaging (mg per vial), not "promotions" or "limited-time discounts."
Why an unusually low price is a reason for caution
Synthesizing and purifying a peptide to research-grade purity costs money, and so does independent lab testing of each batch. When a price is noticeably below market, that almost always means one of those steps was cut: either the purity is lower than claimed, there's no COA at all, or the COA doesn't actually correspond to that specific batch. Asking "does this seller have a fresh, independent report for this exact batch" is a practical way to filter out the riskiest offers before you pay.
COA: how to check quality before ordering
Independent labs, not self-reported results
Longeva submits its own samples to third-party labs for testing, Janoshik, Testides, Uzorak, North American Diagnostics, rather than relying on paperwork from the raw-material supplier. That's what independent verification means: the lab has no stake in the sale.
An important clarification: none of these labs holds ISO 17025 accreditation. They are independent third-party laboratories, and that's the accurate way to describe them, without the word "accredited," which is often misused on this market.
COA publication covers most batches but is not a 100% guarantee for every single one without exception. The accurate statement is that batches are accompanied by COAs and reports are published in an open archive, not that "every batch" carries a certificate.
What to look for in a COA: purity, identity, batch
A proper retatrutide report in Longeva's archive should show: the named independent lab, the test date, the specific batch number, and an actual purity figure, not a generic "tested" claim. Always check the current report with this data in the open COA archive, not in this article.
Before ordering, open the COA archive filtered for retatrutide and match the batch number in the report against the number on the label of the vial you receive. If the numbers don't match, that's a reason to contact support, not to take it on faith.
What to check before buying retatrutide (checklist)
- Is there a fresh COA, and does the batch match the vial. The report date shouldn't be from a previous supply cycle, and the batch number should be readable on the label you actually received.
- Who issued the COA. An independent third-party lab (Janoshik, Testides, Uzorak, North American Diagnostics), not the seller itself or the raw-material manufacturer.
- Is the price in line with the market. A price noticeably below competitors is a reason to check the COA twice as carefully, not a reason to rush the payment.
- Shipping and storage conditions. A lyophilized peptide is sensitive to transport conditions, so confirm how it's packaged and how long delivery takes.
- Is the product status stated transparently. A seller should plainly say "research material, not a medicine", not stay silent about it, or worse, promise a therapeutic effect.
Delivery and payment
Longeva ships from Ukraine via Nova Poshta, Ukraine's national parcel network (branch pickup, parcel locker, or courier), with an estimated delivery time of 1-3 days within Ukraine at the carrier's rates. Payment is accepted by Visa/Mastercard card with 3-D Secure, as well as cryptocurrency (USDT/BTC/ETH) and bank transfer. Exact delivery times and payment-method availability for your location should be confirmed at checkout.
Storage and handling (research use)
A lyophilized peptide is stored differently from a ready-made solution and has its own temperature and shelf-life requirements. We deliberately do not lay out a step-by-step reconstitution or injection procedure here: these are laboratory-handling parameters, not self-treatment instructions. Sources and the full protocol are available in the retatrutide dosing documentation, presented there in an educational, not promotional, context.
Retatrutide, tirzepatide, and semaglutide: the difference
The three peptides differ mainly in mechanism and regulatory status. Semaglutide, a single GLP-1 receptor agonist, is already registered as a medicine under the brands Ozempic and Rybelsus. Tirzepatide, a dual GIP/GLP-1 agonist, is registered under the brand Mounjaro. Retatrutide goes further mechanistically (a triple GIP/GLP-1/glucagon agonist), which is exactly why it's still in clinical trials rather than on a pharmacy shelf.
We don't rank these three substances by efficacy: each has its own evidence base at its own stage, and comparing figures across different trial phases isn't valid. For a specific molecule, see the tirzepatide and semaglutide product pages, and for a detailed mechanism comparison see "Semaglutide, tirzepatide, retatrutide: the difference".
Frequently asked questions
Is it legal to buy retatrutide in Ukraine?
We don't provide legal advice, so we won't state a general legal conclusion on your behalf. Longeva's positioning is clear: retatrutide is sold as a research material (research use only), not a medicine for self-administration, and the buyer is responsible for how they use the material they purchase.
Is it a medicine?
No. Retatrutide is in clinical trials and has not been registered as a medicine by any regulator. Longeva sells it as a reagent for research purposes.
What effect does retatrutide have, how much weight can be lost?
We deliberately don't cite any efficacy or weight-loss figures on this page. Retatrutide remains the subject of clinical trials, its effects are studied under controlled conditions, and retelling that data as a promised outcome for a buyer would be dishonest. Anyone who wants the published scientific data should read the primary source[^1].
How is retatrutide's quality confirmed at Longeva?
A batch with a published report has been checked by an independent third-party lab. Reports are available in the open COA archive, searchable by name or batch number, always showing current data for the batch in stock.
How much does retatrutide cost and how do you ship orders?
The current price is always on the product page. Delivery via Nova Poshta, Ukraine's national parcel network (branch, parcel locker, or courier), payment by card or cryptocurrency.
Summary and next step
Buying retatrutide from Longeva means getting a research material with an independently verified batch and a transparent price, with no promised outcome. Before ordering, check the current price and availability on the product page, and confirm there's a fresh COA for the batch being shipped.
To repeat: this is a research material, not a medicine, and this article is not medical advice or a guarantee of any outcome.
