Frequently Asked Questions
Product Specifications
What is this blend?
This is a dual-peptide analytical reference blend containing two synthetic 39-amino acid acylated peptides: Retatrutide (10mg, CAS 2381089-83-2, C₂₂₁H₃₄₂N₄₆O₆₈, 4731.33 Da) with C20 diacid fatty acid modification, and Cagrilintide (2.5mg, CAS 1415456-99-3, C₁₉₄H₃₁₂N₅₄O₅₉S₂, 4409.10 Da) with eicosanedioic acid modification and a Cys3–Cys8 disulfide bridge. This product is supplied strictly as an analytical reference standard for laboratory research.
What analytical data is provided?
Each batch includes a comprehensive Batch Verification Report (BVR) containing manufacturer analytical data for both peptide components: HPLC purity (Reta 99.37% / Cagri 99.13%), peptide content (Reta 92.19% / Cagri 95.49%), ESI-MS molecular weight confirmation, assay results (Reta 99.45% / Cagri 103.14%), amino acid analysis, Karl Fischer water content, pH measurement, solubility confirmation, residual solvents results, bacterial endotoxins, and microbial limits results. Access via QR code or online verification portal.
How do I verify my batch?
Three methods: (1) Scan QR code on product label, (2) Click verification link in order confirmation email, (3) Visit aventrislabs.com/verify and enter batch ID. All provide instant access to your batch-specific Batch Verification Report with complete analytical data for both blend components.
Why does the powder look smaller than other suppliers?
Aventris peptides are filler-free. Many suppliers add mannitol or other bulking agents to make the powder appear larger in the vial. Our vials contain only pure lyophilized peptide — nothing else. Less visible powder actually means a purer product with no unnecessary additives. Learn more at aventrislabs.com/peptide-fillers-explained.
What is the shelf life?
Typically 24 months when stored in sealed vial at -20°C or below, protected from light and moisture. Specific retest date listed on Batch Verification Report.
What are the CAS numbers?
Retatrutide: CAS 2381089-83-2 (MW 4731.33 Da, C₂₂₁H₃₄₂N₄₆O₆₈). Cagrilintide: CAS 1415456-99-3 (MW 4409.10 Da, C₁₉₄H₃₁₂N₅₄O₅₉S₂). Both confirmed in the Batch Verification Report.
Is this a pre-order product?
Yes. This product is currently available for pre-order. You will be charged at time of purchase and your order will ship as soon as stock arrives. Pre-ordering secures your allocation.
