How does the thyroid hormone Triiodothyronine T3 prevent muscle loss in Cutting?

When bodybuilders use Triiodothyronine T3, it is usually used during the cutting phase, which increases the basal metabolism, reduces fat and prevents muscle loss. Previously, T3 increased the basal metabolism and reduced fat, and today we will focus on how it can prevent muscle loss.

In the cutting stage, it is mainly necessary to lose the fat stored during weight gain, obtain a more linear muscle appearance, and retain as much muscle as possible in this process to prevent the loss of muscle. Triiodothyronine T3 just happens to reduce fat and prevent muscle loss.

In the process of Cutting, bodybuilders need to control their diet while increasing their exercise. In this process, the energy intake is often less than the energy consumed during exercise, leaving the body in a hungry and low energy state. During this process, the body preferentially breaks down muscles for energy.

Triiodothyronine T3 prevent muscle loss in Cutting

At the same time, in the previous article about rT3, we know that the amount of rT3 produced by the body increases when the body is hungry or in a low energy state. rT3 further lowers the body’s basal metabolism and begins to conserve fat. At the same time, rT3 competes with T3 for receptors, making T3 ineffective.

This is very bad for fat loss and muscle preservation in the cutting stage.

Skeletal muscle is a direct target of the thyroid hormone Triiodothyronine T3, which regulates stem cell proliferation and differentiation, and muscle fiber metabolism. In the experiment, T3 to prevent hunger mediated metabolic changes, offset the hunger caused by muscle loss, which retained the muscle quality.

Instead of preventing muscle loss by simply increasing anabolism, and without altering normal protease-mediated catabolism, T3 directly regulates muscle metabolism to counteract muscle loss.

How to prevent muscle loss in the Cutting stage or PCT stage is a very important problem, which is to some extent more difficult than acquiring muscle. The perfect muscle that Bodybuilders pursue is definitely not that bloated look, and cutting is a very important lesson for bodybuilders. Losing fat and preventing muscle loss during the cutting phase, Triiodothyronine T3 does it.
