Summary

Men who got a strong dose of testosterone while eating very little and working hard gained more muscle than those who got a fake shot — but they didn’t get stronger or eat more.

Surprising Findings

Muscle protein synthesis declined equally in both testosterone and placebo groups, despite testosterone boosting molecular anabolic signals like androgen receptor content and translational capacity.

Common belief: more anabolic signaling = more muscle growth. But here, the signals were up — yet actual muscle building (protein synthesis) didn’t improve over placebo.

Practical Takeaways

Consider testosterone’s role in preserving lean mass during extreme calorie restriction — e.g., military ops, famine survival, or extreme fat loss phases.
