Compare the substance name and content per vial first. Retatrutide single vials and the kit have separate listings. Check the documentation for each variant: a report for 10 mg does not verify another variant.
Questions about this category
Is the stated amount per vial or per kit?
The product name gives the content per vial. A kit also specifies the vial count. The product page shows the price per vial and the total pack price.
How do I check batch documentation?
Open the product page and check its COA status. Match the name, content and batch number to the report. Related or missing documentation does not verify the exact sales batch.
What are these products intended for?
For laboratory research only. Products are not intended for human or veterinary use. Product information does not provide dosing or administration advice.
