Is PDA with TB-500 legal in Australia?

The 2026 stand-in for the Wolverine stack. It pairs a salt form of the BPC-157 peptide with the piece of protein sold as TB-500. There is not one published paper on pentadeca arginate. So the blend borrows its evidence twice. It borrows from a peptide it is a salt of, and from a protein that one ingredient is only a small piece of. Vial sizes differ from seller to seller.

Pentadeca arginate, or PDA, is sold as an upgrade to BPC-157. It is the same chain of fifteen building blocks.

How it works: People assume PDA works like BPC-157 because it is the same peptide chain. Nobody has tested that for the arginate form.

Approval history: Not approved. No regulator has ever reviewed pentadeca arginate under that name. It has the same peptide sequence as BPC-157, and FDA staff who reviewed BPC-157 in July 2026 found no adequate human data.

Registers or lists medicines and health products on the ARTG, its official register. It also sorts substances into schedules in the Poisons Standard. Many peptides are Schedule 4 (prescription only). So having them without a prescription, or importing them for yourself, is restricted. That is true even when no product is registered.

The legal category above is how The Longevity Archive reads Therapeutic Goods Administration listings for PDA with TB-500 on the reviewed date. It is not a legal opinion. Rules change. Bringing a compound into the country, prescribing it and owning it can each be treated differently. Check with the agency before you act on anything here.

Whether PDA with TB-500 is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status in Australia. Before you compete or get tested, look up PDA with TB-500 by name on the Prohibited List, or look up a named product in Global DRO. Under the World Anti-Doping Code, category S0 bans, at all times, any drug-like substance that meets two tests. No other section of the List covers it. And no government health regulator anywhere has a current approval for it as a treatment in people. Many substances that are approved somewhere are banned by name in another section. So approval does not mean a substance is allowed in sport.
