For Underactive Thyroid "I was on Synthroid only for 8 years after being diagnosed with Hypothyroidism. My dose was changed many times over that time frame by 4 different Endocrinologists, but I still felt bad: weight gain, fogginess, depression, chronic fatigue, you name it. 6 weeks ago, I was put on 10 mcg of Cytomel by a new doc that I am seeing 100 miles from my hometown, and I am happy to say that for the first time in 8 years, I have relief from my symptoms. I have lost 10 pounds in 6 weeks. I am happy, not in a fog anymore, and I have the energy to enjoy life once again. The Cytomel made all the difference."

For Underactive Thyroid "My doctor and I tried every T4 medication out there, and although I felt better, I still wasn't right. After 2 years, he switched me to Cytomel, and I immediately knew I had found the solution. All the hypo symptoms disappeared - constipation, depression, weight gain, and exhaustion. My cholesterol dropped to 140... in fact, all my blood work is excellent. It's very discouraging to know you're doing everything right - diet, exercise, sleep - and not only do your lab numbers not respond, but doctors tend to think you're not telling them the truth. Finally found a doctor that believed me; finally found the right medication. Life is good!"

For Hypothyroidism, After Thyroid Removal "An endocrinologist put me on the 50 mg per day post TT. I felt tremendous. Then my insurance changed, and I had to find a new doctor. The new doctor refused to prescribe Cytomel. So for several years, I’ve been on Synthroid 200 and 300, and then Nature-Throid 3 grains. The Nature-Throid won out over the Synthroid by far. But my total T3 and FT3 were still tanked. I began seeing a functional medicine doctor who suggested T3-only medication. WHAT A LIFE CHANGER! I take 25 mg per day. Gone is the anxiety, mood swings, depression, weight gain, brain fog, and insomnia. I feel like a brand new person at 62. My doctor follows my labs closely, and all thyroid levels are in range (FT3 upper range, FT4 mid-range). I highly recommend trying this monotherapy if you don’t have a thyroid gland and other medication regimens have failed."

For Underactive Thyroid "Upon 5 days of taking Cytomel at a dose of 5 mcg per day, I had burning rashes on my chest up to my ears. Was taken to the ER 3x for tachycardia, heart failure, thyroid failure, sweating, confusion, arrhythmia, panic attacks, nausea, pain, twitching on the left side of my body, and more. Thyroid failure continued after stopping the medication, still to today not recovered. It is 10 months after the fact, and I have permanent damage. Tachycardia, nervous system, thyroid dysfunction, hair loss, excessive weight gain, 4 hours of functionality per day at most. I lost the ability to work and function like a normal person at 43 years old. I cannot exercise nor do simple chores without raising my heart rate excessively and blood pressure. I had perfect blood pressure and heart function prior to taking Cytomel."

For Underactive Thyroid "Started Cytomel 5 mg about 8 days ago. As my T3 was low. And just did not feel well. I had hair loss, weight gain, major constipation, and very irritable, dry skin. I am hoping to feel better and be more regulated in many ways. I am curious what everyone’s T3 numbers were before starting. Cytomel may be too soon for me to notice any change yet? Thank you."
