What this means

- 02
"Research use only" is a vendor label, not a legal category that permits human use. It does not exempt a product from medicines law.
- 03
Importing, supplying or promoting it for human use can fall under medicines legislation in Canada. This page is general information, not legal advice.
What CMS-121 is
A Salk Institute fisetin derivative described as a 'geroneuroprotector' that improved memory and reduced brain lipid damage in mouse models of Alzheimer's; still in animal toxicology, yet already sold as a research chemical.
CMS-121 was engineered to be more potent and brain-penetrant than fisetin. In mouse Alzheimer's models it preserved cognition and reduced lipid peroxidation, acting in part through fatty acid synthase.
Mechanism: Inhibits fatty acid synthase and lipid peroxidation, reducing neuroinflammation and preserving neuronal energy metabolism in aging brain.
Regulatory history: Preclinical; not approved
How Health Canada treats this kind of product
Authorises drugs for sale through a Notice of Compliance and Drug Identification Number. A compound that is not authorised for sale cannot lawfully be sold for human use, and personal importation of prescription drugs is limited.
The classification above is the The Longevity Archive reading of Health Canada, Health Products and Food Branch listings for CMS-121 at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
