Questions (9)

What is AOD-9604?

AOD-9604 (AOD-9604 (Anti-Obesity Drug 9604; hGH fragment 176-191)). Modified C-terminal fragment of human growth hormone (residues 176-191). Proposed to stimulate lipolysis and inhibit lipogenesis without the IGF-1/glycaemic effects of full GH; clinical fat-loss efficacy not established in trials.

What is AOD-9604 used for?

Commonly discussed uses: fat-loss research interest, joint/cartilage research. There is both human and animal/preclinical research, though the depth and quality vary by indication. Note: most uses are not approved indications.

How does AOD-9604 work?

Mechanism: Modified C-terminal fragment of human growth hormone (residues 176-191). Proposed to stimulate lipolysis and inhibit lipogenesis without the IGF-1/glycaemic effects of full GH; clinical fat-loss efficacy not established in trials.

Is AOD-9604 safe?

Reported considerations: well tolerated in trials at studied doses, long-term data limited. There is both human and animal/preclinical research, though the depth and quality vary by indication. Clinical weight-loss trials did not demonstrate efficacy at endpoints; not approved. Has GRAS-affirmed status for some non-drug uses in the US (not a therapeutic claim). This is not a safety endorsement; safety data for unapproved compounds is incomplete.

What is the typical dose of AOD-9604?

Commonly cited ranges (educational reference, not a recommendation): low 250mcg/day, typical 300-500mcg/day, high 500mcg/day. Administration: subcutaneous, oral (investigated). Half-life: short.

Is AOD-9604 legal in Australia?

Australian status: Not ARTG-registered (developed in AU as a drug candidate; trials did not meet endpoints). Clinical weight-loss trials did not demonstrate efficacy at endpoints; not approved. Has GRAS-affirmed status for some non-drug uses in the US (not a therapeutic claim). General regulatory context: most active peptides are Schedule 4 and require a prescription; import via the Personal Importation Scheme requires a valid Australian prescription for prescription-only goods.

How do you store AOD-9604?

Reconstitution/storage reference: 2ml BAC water per 5mg vial; storage: refrigerated.

What is AOD-9604 commonly stacked with?

Commonly discussed combinations (anecdotal for unapproved compounds): AOD-9604 + fragment protocols (anecdotal). Stacking increases interaction/safety uncertainty.
