Will t3 cause muscle loss?

Excessive t3 will cause muscle loss. If you have hypothyroidism and you bring your levels back to normal, it can increase muscle.

That’s because T3 (fT3) is what’s responsible for metabolizing testosterone on the liver.

One time I purposely took too much cynomel. My LDL small particles were super low.

From AI
Overview
The liver plays a crucial role in metabolizing both thyroid hormones (T3 and T4) and testosterone. T3, the active form of thyroid hormone, is primarily converted from T4 in the liver. The liver also metabolizes testosterone, breaking it down into various products for excretion. While there's a complex interplay between thyroid hormone and liver function, including its impact on lipid metabolism and glucose regulation, there's less direct evidence of T3 specifically metabolizing testosterone in the liver. Instead, the liver's role is more about converting T4 to T3 and then metabolizing testosterone.

The muscle cells will get more energy restored to normal functioning compared to hypothyroid state.

Most say yes but i think it's just due to loss of muscle glycogen am curious to any increased fat burning from using it 25-50mcg

Cytomel can cause protein turnover in which the rate of protein degradation exceeds the rate of protein synthesis, leading to substantial muscle mass loss.

Excessive t3 will cause muscle loss. If you have hypothyroidism and you bring your levels back to normal, it can increase muscle.

also, when you running low on T3, the body will secrete more cortisol/adrenaline to compensate, that its self cause muscle loss

What would be considered a replacement dose of T3/T4?

If you can convert t4 into t3 you only need t4
