The Claim
In young, untrained males undergoing 16 weeks of resistance training, increases in skeletal muscle androgen receptor (AR) protein content are associated with greater muscle fiber hypertrophy, explaining approximately 25% of the variability in hypertrophic response, suggesting that intramuscular AR adaptation may be a key determinant of individual responsiveness to training.
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.
When young guys who’ve never lifted weights before train with weights for 16 weeks, those whose muscles develop more androgen receptors tend to grow bigger muscles—and this receptor increase might explain about a quarter of why some people grow stronger or bigger than others.

What the research says
1 studyStudy: Muscular and Systemic Correlates of Resistance Training-Induced Muscle Hypertrophy
The study found that guys who gained more muscle also tended to have more androgen receptors in their muscles after training—even though the average didn’t change much—so having more receptors seems to help some people build muscle better than others.
