If you are looking to buy semaglutide as a laboratory reference material, this page sets out what Lumo Peptides lists under that name and what each pack costs. Semaglutide appears here in two forms, a lyophilised vial in three pack sizes and an oral tablet. Below the price table you will find the chemistry of the molecule, how it differs from neighbouring compounds in the same range, how the material is handled and stored, and how a parcel reaches the United Kingdom or Ireland.
Everything described here is intended for research and teaching. Semaglutide is not offered as a medicine, a supplement or a cosmetic, and we make no statement about what anyone would observe with it.
Price and packaging
| Product | Pack | Price | Price per mg |
|---|---|---|---|
| Semaglutide | Vial, 10 mg | € 64,95 | € 6,50 |
| Semaglutide | Vial, 20 mg | € 84,95 | € 4,25 |
| Semaglutide | Vial, 30 mg | € 109,95 | € 3,67 |
| Semaglutide oral | Tablets, 500 mcg | € 79,95 | Not stated |
The three vial sizes belong to one listing, the semaglutide vial. Divide each price by its pack size and the 30 mg vial comes to € 3,67 per milligram, the 20 mg to € 4,25 and the 10 mg to € 6,50, so on this molecule the largest vial does carry the lowest unit price. That is not a rule across our catalogue, where the biggest pack is sometimes the dearer one per milligram. The oral form is priced per pack and carries no per-milligram figure, since that turns on the tablet count too.
What semaglutide is
Semaglutide is a synthetic analogue of human glucagon-like peptide-1, a name usually shortened to GLP-1, and it belongs to the class of GLP-1 receptor agonists. It carries CAS number 910463-68-2 and the molecular formula C187H291N45O59, for an average molecular mass of about 4113.58 g/mol. That mass is large for a peptide and small for a protein, so it is weighed out in milligrams per vial rather than in international units.
The backbone is thirty-one amino acids long and follows GLP-1(7-37) with two substitutions. Position 8 carries alpha-aminoisobutyric acid in place of alanine, and position 34 carries arginine in place of lysine, which leaves a single free lysine at position 26. Onto that lysine a side chain is built: a gamma-glutamate linker, two spacer units of 2-(2-(2-aminoethoxy)ethoxy)acetic acid, and an eighteen-carbon fatty diacid at the far end. The diacid tail is the feature the literature returns to most often, since it gives the molecule an affinity for serum albumin.
Where it sits in the catalogue
Several molecules in our metabolic range are routinely confused with semaglutide. Tirzepatide is a thirty-nine amino acid peptide addressed to two receptors, GIP as well as GLP-1, and it has a page of its own at buy tirzepatide. Retatrutide, from € 89,95 for 10 mg to € 299,95 for 60 mg, is described as a triple agonist, adding the glucagon receptor to those two. Cagrilintide at € 59,95 for 5 mg is not a GLP-1 analogue at all but an analogue of amylin. Orforglipron at € 320,95 for 6 mg is not a peptide at all: it is a small molecule aimed at the same receptor, supplied as a tablet. The wider range is set out on buy peptides.
Form, handling and storage
A vial holds a lyophilised cake. Reconstitution is done with bacteriostatic water, run slowly down the inside wall of the vial rather than aimed at the cake, since a jet onto the powder can foam it. Swirl gently until the cake has dissolved and the liquid is clear, and do not shake. Unopened vials keep at room temperature away from light. Once reconstituted, the vial goes in the fridge rather than the freezer, because freezing and thawing is hard on a peptide solution.
Tablets are simpler. Keep them dry and dark in the original blister at room temperature, away from humidity. Whichever form is on the bench, label the vessel with the batch number from the certificate, since that is the only link back to the analysis on file.
Shipping and analysis
Everything ships from the Netherlands. Delivery to the United Kingdom is a flat € 15,95 and free from € 200; to Ireland it is a flat € 14,95 and likewise free from € 200. All prices on the site are in euros.
The United Kingdom is outside the European Union, so a parcel to a British address is an import. Any import VAT or duty that falls due is charged by the carrier to the recipient rather than collected by us at checkout. Ireland is inside the European Union, so no import charge of that kind arises there. Every batch is analysed and a certificate of analysis is available.
Frequently asked questions
What may I use this for?
Laboratory and research purposes only. It is not for human or veterinary use, and we give no instructions for use of any kind.
Why is there no price per milligram for the oral form?
A per-milligram figure needs the strength and the tablet count together. We list the strength, so rather than print a number that could mislead we leave the column blank.
Will I be charged customs on a British delivery?
Possibly. A parcel to the United Kingdom crosses a customs border, and any import VAT or duty is assessed on arrival and billed by the carrier to the recipient. For an Irish address this does not arise.
What does the certificate of analysis cover?
It records the identity and measured purity of one specific batch, the analytical method used, and the batch number printed on the vial or blister. Quote that number in any correspondence about the material.
