Questions
Is Retatrutide a medicine?
No. Retatrutide 20 mg is sold as laboratory research material, not as a licensed medicine.
Who packs this?
EVOLV PEPTIDES has packed Retatrutide 20 mg in the South of England since 2018. The lot number is marked on every vial. Contact hello@evolvpeptides.co.uk.
What does HPLC ≥99% mean here?
HPLC ≥99% is a batch-release specification: the lot was checked against that threshold before packing. It is not independent clinical proof, not a sterility certificate, and not a licence for human use.
Is a paper COA in the box?
Every listed batch has a certificate of analysis. Email the order id or the lot on the vial to hello@evolvpeptides.co.uk and the file for that batch is sent. A paper certificate is not in the carton.
When does it ship?
Packed in the South of England. Next working day across the UK from the South of England when ordered before 14:00 on weekdays, payment cleared. Highlands, islands and Northern Ireland can add a working day. Free UK tracked shipping on orders over £20. Plain outer carton. No compound name on the outside.
Is this powder or pre-mixed?
Retatrutide 20 mg is lyophilised powder. EVOLV ships lyophilised peptide as powder in a sealed vial. Bacteriostatic water, when listed, is a separate laboratory solvent SKU — not included in the peptide carton and not a human reconstitution kit.
Who handles reconstitution?
You do, under your laboratory SOP. EVOLV packs the vial and ships it. We do not issue dosing, injection, or reconstitution-for-humans advice.
Is this for injecting?
This shop does not supply medicines or give injection advice. Vials are packing for laboratory research material.
What sizes of Retatrutide does EVOLV list?
Retatrutide is listed as 5 mg, 10 mg, 15 mg, 20 mg, 30 mg, 40 mg, 50 mg, 60 mg. This page is Retatrutide 20 mg at £49.98. Each size has its own URL.
What is the CAS number for Retatrutide?
Retatrutide 20 mg is catalogued under CAS 2381089-83-2. Match CAS and milligram amount when you compare listings.
How does EVOLV price Retatrutide in the UK vs Solent?
Live EVOLV price for Retatrutide 20 mg is £49.98. Solent Peptides advertised £49.99 for the same amount on 2026-09-19 (https://www.solentpeptides.co.uk/product/retatrutide-20mg). Same CAS and milligram amount only. See /compare.
Is this the same as Wegovy, Mounjaro or Ozempic?
No. GLP-class research listings are not Wegovy, Mounjaro or Ozempic. Those are MHRA-authorised medicines supplied through clinics. Retatrutide 20 mg is a lyophilised research chemical.
