Hey Chloe,
Gosh, your TSH is awefully low and close to being hyperthyroid. But, remember the TSH doesn't reach a steady level til *6 weeks* after you have been on a stable dose of thyroid medication. The T4 is the inactive hormone varies tremendously on the thyroid binding proteins in the blood. What is more accurate is the "Free T4" which the free part that gets converted to T3 and goes into the cell and speeds up the metabolism. Becareful with high thyroid levels ... over time can cause heart arrhymthias, weak bones, weak heart, etc.

PS T3 and T4 just refer to the number of iodine molecules on the thyroid hormone. T4 has one iodine cleaved off to make T3.
