Retatrutide 10mg

Whichever term you searched — retatrutide, retatrutide peptide, or the shorthand "Reta" — this is the page. All three name the same compound, LY3437943, and there is no separate product behind the abbreviation. This 10mg vial is our standard retatrutide listing: the entry fill, the lowest ticket, and the one with a published certificate for the exact lot in the box.

Two larger fills exist for laboratories that need them — the Retatrutide 20mg vial for an extended protocol, and the Retatrutide 30mg vial where a long study should finish on one lot number rather than three. All three are the same synthesis at the same ≥98% HPLC-UV specification.

The word "peptide" is the one that matters here, because it describes what we sell. This is 10mg of lyophilised LY3437943 powder in a sealed vial, which the researcher reconstitutes at the bench. It is not a solution, not a device, not a finished dosage form of any kind — nothing in this catalogue is.

Each lot is independently assayed to ≥98% purity by HPLC-UV with mass-spectrometry identity confirmation, and the signed certificate for the lot you will receive can be viewed on this page rather than promised on request. A stated fill weight, a stated purity floor, a named laboratory and a published document is the whole of what a materials supplier can honestly offer, and it is what separates this listing from a consultation.

We price by the vial and by the milligram, because those are the two units a lyophilised powder is actually bought in. The 10mg vial is the entry point at £49.99, which is £5.00 per milligram. The 20mg fill is £89.99, or £4.50 per milligram, and the 30mg is £124.99, or £4.17 per milligram — so the rate falls as the fill rises, and the 30mg holds the lowest per-milligram figure of the three.

Choosing between them is choosing between unit cost and how long one lot number lasts, not between strengths. There is no monthly price, no course price and no per-dose price for anything in this catalogue, and there could not be: a monthly cost presupposes a monthly quantity for a person, and no such quantity exists for a compound no regulator has licensed.

The price shown in the buy panel above is the authoritative current figure if this paragraph ever falls behind it.

A lipidated 39-mer is amphipathic enough to denature at an air–liquid interface, which is why agitation and foaming matter more here than for a short unmodified peptide.

Once reconstituted, refrigerate at 2–8°C and use within 28 days; do not refreeze. These are solvent volumes for putting powder into solution. They are bench handling data, and they are not a dose.

Every Retatrutide 10mg lot dispatched by UK Peptides is independently analysed by an accredited independent laboratory — two of Europe's most established third-party peptide testing laboratories — for HPLC-UV purity (≥98%), mass-spectrometry identity confirmation, residual solvent profile and visual integrity. The signed PDF for the exact lot you receive is downloadable directly from this page and indexed on our lab reports page.

It is the unedited document, not a marketing summary, and the lot number on the vial sticker matches the lot on the certificate. One caution belongs here rather than in the small print: retatrutide's public chemical identifiers are weaker than those of most compounds we stock.

No PubChem record resolves for retatrutide, for LY3437943 or for the commonly cited CAS number — the CID widely circulated for it in fact returns tirzepatide — and the mass usually quoted, approximately 4,731 Da, is reported rather than verified, with at least one source giving a formula heavier by more than rounding can explain.

Read the mass from the certificate for your lot and check it by mass spectrometry rather than against a figure found online. Our molecular-weight article sets out exactly where the disagreement sits.

Searches for retatrutide often arrive from a different question than the one this page answers. How much to give, how quickly it acts, what it does in a person, whether it is safe for someone to take, how to obtain it as a treatment — none of those have an answer here, and not because we are being coy.

What we sell is the material: a sealed vial of tested, documented lyophilised powder. The questions this page will not answer are answered properly in our research library instead of being left to guesswork:

UK Peptides is a UK-registered research peptide supplier working from Manchester, with a registered UK address behind the sale. Stock is held in temperature-controlled storage, orders placed before 6pm GMT on a working day are dispatched the same day by Royal Mail Tracked 24, and every lot for which we publish a certificate carries a signed document from an independent laboratory at a stable URL rather than one emailed on request.

Where we do not hold a published certificate — currently the 30mg fill — we say so on that product page rather than implying one exists. No grey-market sourcing, no overseas customs step, no anonymous fulfilment and no fabricated documentation. What we do not do is equally load-bearing: we do not consult, prescribe, dispense or advise on use, and nothing in this catalogue is sold as a treatment.
