What this means
- 01
No product containing FGF17 is approved by Health Canada for any use in Canada, so nothing on the market is authorized for people.
- 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 FGF17 is
The factor identified when young cerebrospinal fluid was infused into aged mouse brains. In humans it is known for a different reason: FGF17 mutations cause congenital hypogonadotropic hypogonadism.
A 2022 Nature paper took a different route into the young-blood question by asking about cerebrospinal fluid rather than plasma, on the reasoning that CSF is the immediate environment of brain cells. Infusing young CSF directly into aged mouse brains improved memory function.
Mechanism: In mice, young cerebrospinal fluid boosts oligodendrocyte progenitor proliferation and differentiation in the aged hippocampus through serum response factor, a transcription factor driving actin cytoskeleton rearrangement whose expression falls with age in hippocampal progenitors. FGF17 was identified by screening CSF for activators of that pathway, and FGF17 infusion alone induced progenitor proliferation and long-term memory consolidation in aged mice while FGF17 blockade impaired cognition in young mice.
Regulatory history: Not approved and never administered to a human. No registered trial of FGF17 for any indication could be located.
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 FGF17 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.
