What you are buying
Retatrutide is supplied as a lyophilised vial, or pre-filled pen graduated in dial units. Reported half-life: Long, supporting weekly intervals in clinical study design. Storage: Refrigerated. Pens must not be frozen. Protect from light.
Retatrutide is also written as LY3437943. The same molecule appears under more than one name, which is worth knowing when comparing listings between suppliers.
Strengths listed
Listed strengths run from 30 mg to 50 mg (30 mg and 50 mg). Where two listings differ only in strength, cost per milligram is the figure that tells you which is better value.
Price
Listings run from £160 to £225. There are 4 listings in the range and 4 are in stock at the time this page was generated. Cost per milligram, where a strength is stated on the listing, is the figure worth comparing.
Price across a range moves on three things: the strength on the listing, the presentation it comes in, and whether the item is held in the UK or has to be imported. For incretin compounds the receptor count tends to track the price, with triple agonists sitting above dual and dual above single.

Buying Retatrutide online
Buying Retatrutide online in the UK comes down to three things: whether the stock is held domestically, what the listing actually contains, and what that works out at per milligram. Stock held in the UK ships without a customs step, which is the difference between an order arriving in days and an order arriving whenever it clears. For an incretin compound the cold chain is the whole question, so where it ships from matters more than where the website is.
Tablets, vial or pen
Retatrutide is listed as pre-filled pen and vial. The presentation is not a detail: it changes the storage, the shelf life once opened, and whether a price comparison against another listing is measuring the same thing.
Retatrutide is also sold as LY3437943, reta, reta peptide and retatrutide peptide
Retatrutide is also written and searched as LY3437943, reta, reta peptide and retatrutide peptide. They are the same compound. Worth knowing when comparing two listings, because a supplier using a different name is not offering a different thing.
Retatrutide for sale
Retatrutide for sale in the UK: 4 listings, 4 showing in stock. Everything listed is held domestically rather than drop-shipped, which is why a stock figure here means the item is in the country rather than on order.
Others in the metabolic and GLP-1 range
Retatrutide sits in the metabolic and GLP-1 group. The compounds below share that grouping, which is the useful starting point when comparing one against another: same group means the comparison is like for like, different group usually means it is not.

|---|---|---|---|
| Tirzepatide | Dual GIP/GLP-1 receptor agonist | 4 | £110 |

Is Retatrutide legal in the UK?
Retatrutide is supplied for laboratory and research use only. It is not sold for human consumption and nothing here is medical advice. Incretin compounds are prescription-only medicines in the UK when supplied for human use. Research material is a separate category and is not a substitute for one. Status varies by compound and the product page is the reference, not this summary.
Does Retatrutide come as tablets, a vial or a pen?

Is Retatrutide the same as the other names it is sold under?
Retatrutide is also written and searched as LY3437943, reta, reta peptide and retatrutide peptide. They are the same compound. Worth knowing when comparing two listings, because a supplier using a different name is not offering a different thing.
How should the price be compared?
On cost per milligram rather than cost per item. A larger presentation at a higher headline price is often the cheaper one once the strength is taken into account.
Is it held in UK stock?
Stock held in the UK ships domestically, with no customs step. The product page carries live stock rather than a cached figure.
Is Retatrutide supplied in a pen?
Supplied as lyophilised vial, or pre-filled pen graduated in dial units. A pre-filled pen is already in solution. A lyophilised vial is a powder that has to be brought into solution before use.
