What this means

Importing, supplying or promoting it for human use can fall under medicines legislation in Canada. This page is general information, not legal advice.
What PTD-DBM is
A topical peptide that unblocks Wnt signaling in the scalp and stimulated hair regrowth and new follicle formation in mice; no human trial exists.
PTD-DBM fuses a cell-penetrating sequence to a motif that displaces the negative regulator CXXC5 from Dishevelled, releasing Wnt/beta-catenin signaling in hair follicle stem cells. In the 2017 Journal of Investigative Dermatology study, topical PTD-DBM, alone and with valproic acid, regrew hair and induced new follicles in wounded mouse skin.
Mechanism: Competitive disruption of the CXXC5-Dishevelled interaction, activating Wnt/beta-catenin signaling in hair follicles.
Regulatory history: Not approved; no IND
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 PTD-DBM 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.
