When male mice can't transport creatine properly, their muscles show signs of weakening because key growth signals are turned down and breakdown processes are turned up.

Creatine transporter (SLC6A8) knockout mice exhibit reduced muscle performance, disrupted mitochondrial Ca2+ homeostasis, and severe muscle atrophy

Cross-Sectional Study

The study looks at mice that can't take in creatine properly and finds their muscles shrink because of changes in key growth and breakdown signals, which matches what the claim says.

Similar Assertions

Male mice that can't transport creatine properly have much weaker muscles — their muscle fibers shrink by over two-thirds and take up less space in the muscle, showing serious damage to fast-moving muscle types.

Male mice that can't transport creatine properly have super weak muscles — their grip gets way worse as they age, and their leg muscles can't produce nearly as much force or power as normal mice.

In male mice that can't transport creatine properly, their muscle mitochondria get way bigger, move to the wrong part of the muscle cell, and get damaged inside — like tiny powerplants going haywire.
