Retatrutide from Southampton
Retatrutide 5 mg ships from Southampton with Solent Peptides. Pre-mixed as standard. Guest checkout, or create an account to track the order. 5 mg lyophilised retatrutide reference peptide for smaller metabolic-pathway assays. The listed aliquot is 5 mg.

Purity and identity

About Retatrutide
5 mg lyophilised retatrutide reference peptide for smaller metabolic-pathway assays. Public identifier CAS 2381089-83-2. Solent Peptides supplies Retatrutide (5 mg) as a defined lyophilised solid for non-clinical laboratory work, dispatched from Southampton after HPLC identity and purity checks. It is not a medicine, not a food, and not a cosmetic. We do not give medical advice or tell you how to use it on yourself. The page is here so you can see what you are buying, the price, and that it comes from Southampton.

Retatrutide is catalogued for metabolic-pathway and receptor-model research (including incretin and mitochondrial literature where relevant). Pages on this site do not describe weight, appetite or clinical use. Laboratory reference material only.
Identity and quality
Each lot of Retatrutide is released after HPLC purity of 99% or greater and identity confirmation against the expected mass for CAS 2381089-83-2. Each lot is HPLC-checked and identity-confirmed before packing. Keep the lot number on the vial with your experimental records.
Laboratory handling
Shipped as a lyophilised powder in a sealed vial. Reconstitute and handle under your laboratory SOP. Keep the lot number with your experimental records. The purchaser is responsible for PPE, institutional approval, and disposal. Not for human or veterinary administration.
