Help dosing T3 and T4 would be appreciated

[nathaniel76]

I have a prescript of T3 and T4, and have been trying to figure out what dosage to use to burn off some fat, I eat very lean 6-8 times daily, 6'2" 225,, Run 3-5miles, 2-3 times a week, do other cardio for an additional 3-4hrs a week and hit the weights for 1.5hrs a day 5-6 days a week. Unfortunately my thyroid issues prevent me losing the remaining fat even with my diet. I am on test therapy and just upped my mg from 200 to 400 weekly. My prescribed amount is T3-5mcg 2 times daily and T4-75mcg once daily, I used this amount with no added benefit only gave me headaches,, So if I am going to do a cycle of of these 2 compounds what dosage and length of time should I do this for. Would appreciate any imput on the issue.

Thanks
