What Bimagrumab is

A muscle-preserving antibody that blocks activin receptors to reduce fat while increasing lean mass, being studied alongside GLP-1 drugs.

Bimagrumab is a monoclonal antibody that blocks activin type II receptors, releasing the brake on muscle growth. In trials it reduced body fat while increasing lean muscle mass, an unusual profile for a weight-loss agent.

Mechanism: Blocks activin type II receptors, neutralizing myostatin and activin signaling to build muscle and reduce fat mass.

Regulatory history: Investigational for obesity / body composition; Phase 2 BELIEVE published 2026

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 Bimagrumab 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.
