Does L-carnitine actually increase androgen receptor content—or has social media exaggerated what the research shows?
In this episode of Muscle Minds, Scott Stevenson presents a detailed breakdown of the Kraemer L-carnitine study behind this popular bodybuilding claim. Scott Stevenson and Scott McNally examine what the researchers actually measured, how the study was designed, what the results showed and the limitations that are often left out of social-media explanations.
The evidence does not support the claim that L-carnitine upregulates androgen receptor content. We also discuss why this proposed effect would matter to bodybuilders, the questions the study leaves unanswered and what can—and cannot—be concluded from its results.
