What this means
- 01
No product containing Ac-SDKP 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 Ac-SDKP is
The N-terminal four amino acids of thymosin beta-4, a natural anti-fibrotic peptide broken down by ACE (which is why ACE inhibitors raise it); animal and human observational data, sold as capsules unlikely to survive digestion.
Ac-SDKP circulates naturally and limits fibrosis in heart, kidney and lung models. Its blood level rises in people taking ACE inhibitors, a well-documented human observation.
Mechanism: Inhibits fibroblast proliferation and collagen deposition via TGF-beta/Smad signaling; degraded by angiotensin-converting enzyme.
Regulatory history: 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 Ac-SDKP 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.
