  • 03

    Injectable or "research use only" versions are not supplements. That label does not make human use lawful, and injectables fall under medicines rules.

What Ketone esters is

Sold to give you the benefits of ketosis without fasting. In trained cyclists, an acute dose made 20-minute time-trial performance worse.

Ketone esters raise blood ketones within minutes, which makes them the most direct way to test whether the ketone bodies themselves produce the effects attributed to fasting and ketogenic diets. That is a genuinely useful experimental tool and it is also why the results are awkward for the marketing.

Mechanism: An ester of beta-hydroxybutyrate, typically the monoester of R-3-hydroxybutyl R-3-hydroxybutyrate, which is hydrolysed in the gut and liver to release free beta-hydroxybutyrate and its alcohol precursor. That raises blood beta-hydroxybutyrate within roughly 30 minutes to concentrations comparable with several days of fasting, without the fasting.

Regulatory history: Sold as a dietary supplement or food for special dietary use. Not an approved drug and not approved for any indication.

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 Ketone esters 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.
