Frequently Asked Questions
Q1: What is the minimum purity specification for peptide sciences retatrutide and how is it verified?
Peptide sciences retatrutide is manufactured to a minimum purity specification of ≥98% as determined by reverse-phase HPLC with UV detection at 220 nm. Each batch is independently tested and the results are provided in a Certificate of Analysis that includes the full chromatogram, peak purity analysis, and integration data. Buyers can request additional testing such as mass spectrometry or amino acid analysis for further verification.
Q2: How should peptide sciences retatrutide be stored to maintain its stability for bulk inventory?
For long-term storage, peptide sciences retatrutide should be kept as a lyophilized powder at -20°C in a desiccated container protected from light and moisture. Bulk inventory should be aliquoted into smaller, airtight vials to minimize freeze-thaw cycles. Under these conditions, the peptide remains stable for up to 24 months. Short-term storage at 2-8°C is acceptable for up to 30 days if the container is kept sealed and dry.
