Name and amount
The large print is the material and the amount in the vial, for example Glutathione 600 mg. The amount is per vial, not per any use, and nothing on the label or this site is a dose.
Purity, CAS number and molecular weight
The side panel carries the identifiers a lab uses to confirm what it has: the stated purity (≥ 99% on the glutathione vials), the CAS registry number (70-18-8) and the molecular weight (307.32 g/mol). These are the details copied onto each product page.
The research use only line
Every vial says Research Use Only. It means the material is supplied for laboratory research and is not a medicine, food or dietary supplement. It is not for human or veterinary use.
