Does YK-11’s follistatin signal demonstrate human muscle growth?

Demonstrated findings

In mouse-derived C2C12 cells, YK11 increased follistatin expression and myogenic differentiation. Blocking follistatin reduced that response.

What might this mean? · interpretation

The experiment supports a follistatin-linked mechanism in this cell model.

What might this mean, and what would change the interpretation?

Cell differentiation is not a measured increase in human muscle mass or strength. Exposure and downstream effects in people remain separate questions.

What would clarify this: Replication, animal functional outcomes and appropriately controlled human studies.

Mechanism to possible human relevance
Working explanation
The follistatin response offers a possible link between androgen-receptor signaling and differentiation in the tested cells.
Possible human implication, hypothesis
Muscle growth is a hypothesis to investigate, not an outcome measured in this experiment.
Evidence that would support it
Independent replication followed by appropriate in vivo muscle-size and function findings.
Evidence that would challenge it
Failure to reproduce the response or no muscle/function benefit at a tolerable exposure.
