Report published
Retatrutide 20 mg is supplied from Bali as lyophilised powder in a sealed glass vial for research use only. The 20 mg strength is the labelled amount per vial. Laboratory measurements are shown separately in the batch record so you can compare the label with the reported results before ordering.
Batch SC-RET-20-0726 has four Janoshik reports commissioned by Sequence Club. One covers identity, amount and purity; the other three cover endotoxin, sterility and heavy metals. Each report has its own task number and verification link in the batch documentation above.
The three amount figures and three purity figures come from three individual vials. Read each as a separate measurement, rather than adding them together or treating them as the contents of one vial. The other testing categories are documented in their own reports; the three-vial scope should not be assumed for every test.
These findings describe the samples analysed and the tests reported. They do not mean every vial was individually tested or establish suitability for human or veterinary use.
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.
