Retatrutide (LY3437943) is a synthetic long-chain polypeptide consisting of 47 amino acid residues. It features a linear peptide backbone with C-terminal amidation and incorporates non-natural amino acids including Aib (2-aminoisobutyric acid) and α‑methylleucine. The molecule is further modified with a C20 diacid fatty acyl side chain linked via a γ‑Glu‑(AEEA) spacer to a lysine residue.

Physicochemical Properties：
Appearance: White to off-white lyophilized powder
Molecular formula: C₂₂₁H₃₄₂N₄₆O₆₈
Molecular weight: Approximately 4731.33 g/mol
Solubility: Soluble in DMSO and aqueous buffers under neutral to slightly alkaline conditions
Storage: Stable under dry, sealed conditions at −20 °C or below; hygroscopic, so protection from moisture is required

Production：
Manufactured via solid-phase peptide synthesis (SPPS), followed by purification and lyophilization to obtain the final product.

NOTE: This product was prepared by chemical synthesis. Used only for research. Not for human use.

1. How to make an order?

Send me message and let me know what you need with quantity , then i will calculate to you.

2. What's the lead time and shipping ways?

We will delivery to the package by USPS, FEDEX, DHL paket and UPS express to you after receive your payment, it would take around 5-15 days to your address.

3. How do i keep the peptides when I receive it ?

Peptides in the form of lyophilized powder can be transported at room temperature by vacuum packaging, while polypeptides in the dissolved state need to be refrigerated at 2°C - 8°C. For long-term storage, peptides should be stored in the form of lyophilized powder store at -20°C or -80°C in a sealed container with desiccant, which can avoid the degradation of peptides to the greatest extent.
