I have been dieting for about 16 weeks now, and I strongly believe my thyroid is fucked up. Ive made some research on the symptoms and since I have so many of them and my weight/fat loss has suffered a major decrease I ve decided to go on T4 (Well, why not T3? Because I dont have access to T3). I am not looking for an extra boost in my metabolism, I just want to get my thyroid back to normal, not supercharge it. My question is, by taking 200mcg/day of T4, how long do you believe is going to take to reach my normal thyroid range again? Days, weeks? Please let me know! Thanks guys!
