I have been using 200mcg of levothyroxine for many years to speed up metabolism. I feel good with this dose and the blood test was in normal range. yea, not bad.
I want to weight loss so I decide to use 400mcg for a month to see the results. I feel very energetic and never feel cold. also always motivated , moise skin, and a lot of benefit. but I didn't lose any weight, may be because I eat a lot as well. The only observed side effect is my heart beat is around 100 per minite.
The blood test with 400mcg looks kinda scary.
I will stop taking levothyroxine for a week and dose with 200 mcg again. I was worried that I am a person with not converting t4 to t3 so I ordered some t3 tiromel a week ago. seems i don't need to use it if t4 works.
I am using the actavis brand levothyroxine 100mcg (this is the only over the counter t4 medicine in Hong Kong and we do not have any t3 medicine).
I always take the medicine in the morning 0700 just right before the breakfast. the blood test is taken at 1730 in the evening.
