A few months ago, my provider (Defy Medical) put me on an NDT (Armour Thyroid), which was gradually built up to 2 grains (76mcg t4/18mcg t3). I did not see any results with this, despite 6x/week exercise + 1600-1800 calories/day. They then prescribed Cytomel , which was built up to 20mcg of t3, and lowered the NDT to 1.5 grains (57mcg t4/13.5mcg t3) for a total of 57mcg t4/33.5 t3.
Since the new dosage, I have been seeing some results, losing roughly 1-1.5lbs a week, give or take. However, this is with taking in 1600 calories per day. Given I’m ~155 lbs and exercise 6x per week, I imagine I should be able to consume more calories and maintain this weight loss pace, while 1600 cals/day would be the very aggressive approach. I want to continue the weight loss, but don’t want my metabolism to adapt to 1600 calories a day.
I feel maybe I should adjust my thyroid dosage? Given all of the above, would it make sense to increase the t3 only medication? Or should I increase the NDT? Defy medical originally said cap it off at 20mcg pure T3+1.5g NDT, but I read of people taking far more T3 only medication. I believe Defy’s main expertise is TRT. I also am not sure if the recent weight loss is due to the adjustment of the T3 medication, or if it was just a matter of the thyroid medication taking it’s intended affect after about 8 weeks of use. I also don’t want an excess of t4 to then convert to reverse t3, which I’ve read can occur.
Thanks for any insight.
