Ignorance. Learn a little more and try again

Hey Jake,

Your arguments make sense, but physiology is more complicated than that. There are way more differences between males and females than just testosterone. In addition, bigger men also gain faster than smaller men, despite testosterone being similar. It seems the role of testosterone is much smaller than what most people expect.

Yes.

So in all reasonableness is it correct to say “men gain more overall muscle”?

Hey Jan,

You refer to an infographic in which testosterone injections build muscle mass even without resistance exercise. However, it’s important to realize that those testosterone injections provided supraphysiological amounts of testosterone (higher levels than the body can produce). In fact, the dose was MUCH higher than the body can produce naturally. While males have higher testosterone levels than females, the difference is very small compared to the amounts you would need to inject to start noticing effects on muscle growth. So to summarize: the difference in testosterone between males and females is too small to matter for muscle growth.

So if MPS is the same in men and women, what is the role of testosterone in building muscle? In another infographic of yours I’ve read that even without resistance training; taking testosterone did increase muscle mass, which would suggest that it does play a role in building muscle.

However, as women have fewer amounts of testosterone than men you’d assume that they build less muscle but this isn’t the case as MPS is the same, as you have demonstrated in this article/infographic. So why does taking testosterone lead to an increase muscle mass even in untrained individuals, but a higher testosterone in men does not lead to (relatively) more muscle mass?

Thanks for answering!

Jan
