What this means
- 01
No product containing SS-20 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 SS-20 is
The sibling of SS-31, the peptide that became the approved drug elamipretide. SS-20 cannot scavenge free radicals at all, which made it the control that proved a point, and it works anyway in rats and mice. There is no human study and no registered trial.
SS-20 is Phe-D-Arg-Phe-Lys-NH2, one of the Szeto-Schiller peptides developed at Weill Cornell. Its interest comes from what it lacks.
Mechanism: Selective targeting of cardiolipin in the inner mitochondrial membrane, where it preserves the methionine 80 to iron ligation of cytochrome c. Ischaemia disrupts that ligation, producing a globin-like pentacoordinated heme that inhibits electron transport and turns cytochrome c into an oxygenase, which peroxidises cardiolipin and drives OPA1 degradation and cytochrome c release.
Regulatory history: Not approved and never submitted. Its sibling SS-31, elamipretide, received accelerated United States approval in 2025 for Barth syndrome. SS-20 has no regulatory status of any kind.
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 SS-20 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.
