The Claim

In obese male non-human primates, the addition of dual GDF8/activin A blockade to semaglutide treatment over 20 weeks results in progressive increases in lean mass and greater fat loss compared to semaglutide monotherapy, with the combination group exhibiting the most favorable changes in HbA1c, LDL-C, and HDL-C.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

In obese male primates, combining a drug that blocks two specific muscle-regulating proteins with semaglutide leads to greater increases in muscle mass and more fat loss than semaglutide alone, along with improved blood sugar and cholesterol levels after 20 weeks of treatment.

  1. Study: GDF8 and activin A blockade protects against GLP-1–induced muscle loss while enhancing fat loss in obese male mice and non-human primates

    Adding a special muscle-protecting treatment to semaglutide helped obese monkeys keep more muscle and lose more fat than with semaglutide alone, and their blood sugar and cholesterol also improved better.
