t3 and t4 purpose?

ad

What is the purpose of t3 and t4. Having trouble finding out what they do.

Thyroid hormones but I don't know much about that and what it does.

I get that they help you lose weight. Anything else?

T3 increases your body's ability to metabolize food.

There are better things out there. These were developed to treat people with hyper/hypothyroid. Taking either will likely screw up your thyroid, that would not be worth whatever minimal weight loss might occur.
