Report published
Tirzepatide is a research peptide labelled 45 mg per vial. Its manufacturing-partner report is linked to the exact batch and the recorded identity, measured amount and purity findings. Compare those analytical fields separately from the product label. Supplied as lyophilised powder in a sealed vial for research use only; the documentation supports the reported analyses within their stated scope.
Batch ZE45-0422 is linked to Janoshik task 153178, commissioned by the manufacturing partner. The submitted sample is recorded as tir 45mg, and the batch record identifies Tirzepatide as confirmed in that analysis.
The recorded measured amount is 52.68 mg and the purity result is 99.927%. These are findings for the analysed sample. The 45 mg label remains the product's labelled strength; the amount result does not establish that every vial in the batch contains exactly 52.68 mg.
This record reports identity, amount and purity without sterility, endotoxin or heavy-metals results. One set of reported figures is not a comparison of multiple individually tested vials. Follow the original report for its sampling details and analytical scope.
For help interpreting the results, read our guide to reading a certificate of analysis (COA). For supplier checks, ordering and delivery, see our guide to research peptide suppliers in Bali.
Store lyophilised vial at −20°C in a dry environment. Keep the vial sealed until required and minimise exposure to light and moisture. Handling should follow standard laboratory practice for research materials.
