What this means

  • 01

    No product containing PTD-DBM is approved by TGA for any use in Australia, 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 Australia. 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 TGA treats this kind of product

Registers or lists therapeutic goods on the ARTG and schedules substances in the Poisons Standard. Many peptides are Schedule 4 (prescription only), so possession without a prescription and personal importation are restricted even when no product is registered.

The classification above is the The Longevity Archive reading of Therapeutic Goods Administration 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.
