When you first start treatment, your doctor will check your thyroid hormone levels about every four to eight weeks. Blood tests will show if your thyroid-stimulating hormone (TSH) is at the right level. The normal range for TSH levels is 0.3 to 4.0 mIU/L. But, your specific target range depends on your health. Finding the right dose can sometimes be a trial-and-error process. And, many things can have an effect.
400 ounce gold bars are up there with the largest gold bars in existence. Because of this there is not just one uniform size that gold bars of this size abide by. While most 400 ounce gold bars will be similar in size, they will not be exactly the same.
Traditional mass for a gold bar is 400 troy ounces (12.4Kg) at 99.5% purity. So, $632,820 USD for a 12.4Kg bar of 99.5% purity. The ones I mention above are the bigger ones like you see in the movies. This is what governments and banks trade with. It's unlikely a regular person would ever see a real one of these.
