The Claim
In mice, inhibition of myostatin activation via SRK-015 increases isometric muscle force by 16–18% in the plantarflexor group and 20–29% in the EDL muscle, with no change in force normalized to muscle weight, indicating that muscle hypertrophy does not impair intrinsic muscle quality.
What the research says
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.
In mice, blocking myostatin activation with SRK-015 increases muscle force in specific muscles without changing the force produced per unit of muscle mass, showing that muscle growth does not reduce the intrinsic strength of muscle fibers.

A protein that normally limits muscle growth is blocked from becoming active, so muscle fibers grow larger without losing their ability to generate force per unit of tissue. The muscle becomes stronger because more contractile material is added, but each part of the muscle works just as well as before.
What the research says
1 studyStudy: Blocking extracellular activation of myostatin as a strategy for treating muscle wasting
This study shows that blocking a specific protein (myostatin) in mice makes their muscles bigger and stronger without making the muscle tissue itself weaker — like growing a bigger engine that still runs just as efficiently.
