The Claim

Higher intramuscular androgen receptor protein content following resistance training is associated with greater muscle hypertrophy in some studies, but findings are inconsistent, with one study reporting no difference between high and low responders.

Roughly balanced

Support and challenge are close. The picture may shift as more studies come in.

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

In plain English

Some people who lift weights and end up with more of a certain protein in their muscles tend to grow bigger muscles, but not everyone sees this link—some people with lots of the protein don’t grow much, and others with less do.

  1. Study: Physiological Differences Between Low Versus High Skeletal Muscle Hypertrophic Responders to Resistance Exercise Training: Current Perspectives and Future Research Directions

    This study found that people who grew more muscle after weight training tended to have more androgen receptors in their muscles, which helps explain why some people build muscle better than others.
