Not a weight-loss clinic
If you want a licensed UK treatment, that is a clinic and a prescription — Wegovy (semaglutide) or Mounjaro (tirzepatide) under MHRA authorisation. This page is chemical supply for laboratory protocols. We do not advise human use, dosing, or injection.
HPLC ≥99% is our batch-release specification, with identity checked against the published mass. It is not independent proof that a vial is safe or suitable for any biological use. We are not enclosing a paper certificate in every box at the moment. Keep the lot number on the vial with your notes.
Retatrutide UK — short answers
Who are Solent Peptides?
Solent Peptides is a Southampton research peptide shop packing HPLC ≥99% vials since 2019. Same email sales@solentpeptides.co.uk. Previously listed in some places as Solent Biopeptides.
What does Solent charge for Retatrutide 30 mg in the UK?
Solent Peptides lists Retatrutide 30 mg lyophilised powder at £67.99 on https://www.solentpeptides.co.uk/product/retatrutide. That is the live catalogue price. We do not sell a research pen or a pre-mixed solution.
Is Solent the cheapest UK retatrutide supplier?
On this dated table, Sable Peptides advertises Retatrutide 30 mg at £66.99, under Solent £67.99, Red Panda £68.99 and Precision £71.59. Same milligram size only. Sable’s figure was checked 9 October 2026 on their product page. Other rows were recorded in September 2026. Prices change. This is not every UK shop.
Is this the same as Wegovy or Mounjaro?
No. Licensed UK weight-loss medicines (Wegovy, Mounjaro and similar) are MHRA-authorised products prescribed through a clinic. Research-use retatrutide is a laboratory chemical packed as lyophilised powder. It is not a licensed medicine and is not for human use.
Is the HPLC claim independently verified?
Each lot is HPLC-checked for identity and purity before packing, and the lot number is printed on the vial. That is our batch-release specification (≥99% HPLC). It is not the same as a licensed-medicine Marketing Authorisation, and we are not currently enclosing a paper certificate in every box.
