How creatine helps muscles depending on energy levels
The regulating pathway of creatine on muscular protein metabolism depends on the energy state.

This study looked at how creatine affects muscle cells from baby chickens when they have enough food or are starving. It found that creatine helps build muscle when energy is low, but only if there’s no glucose around.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

When chicken muscle cells are starved, adding creatine seems to boost a key protein for energy and reduce harmful molecules, which might help the cells' powerhouses work better under stress.
In chicken muscle cells with normal energy, adding creatine seems to boost protein building and turn on key muscle growth switches in the cells.
When chicken muscle cells are starved, adding creatine seems to lower levels of two proteins that make muscles waste away — this might mean creatine helps protect muscles when there's not enough energy.
Creatine helps protect tiny muscle cells from shrinking when they're starved, but only when there's no sugar around — it seems to work only when energy is low.
Taking creatine makes your muscle cells swell, which tells your body to start building more muscle, and insulin makes this happen even better by boosting muscle-building signals and slowing down muscle breakdown.
