Semaglutide 5mg

Semaglutide is a synthetic GLP-1 receptor agonist peptide widely used as a reference material in metabolic research. This page describes a research material supplied for controlled laboratory and analytical work.

The 5mg designation is the nominal quantity assigned to the pen. Confirmation of net peptide content, or the calculation basis behind it, should come from the batch-specific analytical documentation rather than the label alone.

A single pen is £69.99. Two are £68.24 each (save 2.5%), three are £66.49 each (save 5%), five are £62.99 each (save 10%) and ten are £59.49 each (save 15%). Quantity pricing applies automatically at checkout.

The current batch is still awaiting certification, so no document is shown yet. The certificate card on this page displays the live status and will link the PDF the moment it is issued. We never substitute a certificate from a different product or batch.

Semaglutide is described in the literature as a single GLP-1 receptor agonist. Tirzepatide is described as a dual GIP/GLP-1 agonist, and Retatrutide as a triple agonist. All three are research materials here, none is supplied for human use, and this page makes no comparative claim about effects.

Semaglutide is offered here in a single 5mg pen strength. For higher-strength incretin research materials see Tirzepatide 60mg or Retatrutide 40mg. All are supplied strictly for laboratory research use only.

No. Semaglutide is not sold for weight loss, medical treatment, diagnosis or self-administration. It is a laboratory research material, and published findings about any other formulation do not establish equivalence, approval, safety or efficacy for this product.

The commonly reported formula is C187H291N45O59 with a molecular weight of approximately 4114 g/mol and CAS number 910463-68-2. Exact values can depend on salt form and batch-specific factors, so treat the COA as authoritative.

United Peptides supplies this material from a UK-based operation. Identity and purity are assessed by the issuing laboratory using HPLC, and the results are published in the batch COA linked on this page. We do not publish results that are not batch-specific.

Yes. The batch COA is linked on this page. It shows the issuing laboratory, analytical method, units, the reported purity result, the batch or lot reference and the document date. Check that the product name, strength and lot reference match the pen you received before drawing any conclusion from it.

Store sealed, upright and protected from light. Do not allow it to freeze, and avoid prolonged exposure to heat. Follow the conditions printed on the product label and stated in the batch documentation.

Orders placed before 9am UK time are dispatched the same working day. Free UK delivery is Royal Mail Tracked 48 (3-5 working days); Royal Mail Tracked 24 next-working-day is £7.95.

Yes. United Peptides dispatches retatrutide from UK stock to UK addresses only, with same-day dispatch on orders placed before 9am. Buyers must be 21 or over and purchasing for laboratory research. Retatrutide is not a licensed medicine and cannot be prescribed or bought from a UK pharmacy.

Check four things before ordering anywhere: a batch-specific certificate of analysis that names the testing laboratory, a mass-spectrometry identity result alongside the HPLC purity figure, a stated pen format and storage condition, and a UK dispatch address. A supplier who cannot answer all four is not a supplier worth using.

The retatrutide pen price starts at £159.99 for a single 40mg pen and falls to £135.99 per pen at ten pens. Tiered discounts apply automatically at 2, 3, 5 and 10 pens. Cost per milligram falls as pack size increases, so compare listings on the per-mg figure rather than the headline price.

Order through this product page and pay by card or bank transfer. Orders placed before 9am dispatch the same working day. Royal Mail Tracked 48 is free and Tracked 24 is available at checkout. Retatrutide is not available on NHS prescription in the UK, the EU or the US, so a pharmacy is not a route to it.

One sealed pen at the strength shown on this page, supplied in discreet protective packaging with batch documentation. Browse the full shop for other strengths and compounds. No reconstitution is required — this is a prepared pen, not a freeze-dried vial.

Quantity pricing is applied automatically at checkout — 2 pens save 3%, 3 pens save 5%, 5 pens save 10% and 10 pens save 15%. For bulk and wholesale volumes above those tiers, see our wholesale peptides and bulk supply page to request trade pricing. You can also browse the full research peptide range.

Yes, for laboratory research only. This material is not a licensed medicine and is not a controlled drug. You must be 21 or over to order, and it is not an approved medicine — it is not interchangeable with any authorised formulation.

No. It is supplied strictly for in-vitro laboratory research and analytical work. It is not for human or veterinary consumption, injection, diagnosis, treatment or self-administration.
