At the time of those tests, your Free T4 was at about 45% of its range, which is slightly below the 50% recommended as minimum. Your Free T3 was only at 15 % of its range, which is way short of the recommended level of upper third of its range, or as needed to relieve symptoms. So the change to a desiccated med like Armour was directionally correct, but the new dosage was incorrect, since you still had symptoms even with the 125 mcg of T4 and the conversion to Armour was not done correctly. Note also that Vitamin D needs to be about 55-60 and B12 in the very upper end of its range. So you should continue to supplement as needed to optimize.
A good thyroid doctor will treat a hypo patient clinically by testing and adjusting Free T4 and Free T3 as needed to relieve symptoms, without being constrained by resultant TSH levels. Symptom relief should be all important, not just test results, and especially not TSH results when already taking thyroid med. You can get some good insight from this link written by a good thyroid doctor.

When you see your doctor next you need to get him to understand about the correct conversion of the T4 dose to Armour. You need to be on at least 2 grains of Armour, based on my calculations. Also, you need to find out if the doctor is going to be willing to treat clinically as described. If not, then you will need to find a good thyroid doctor that will do so.
Sorry, I should have also asked when you made the switch to Armour.
Last blood work as of 10/23/15 was:
TSH 6.880 High
FT4- 1.23 (Range- 0.80-1.73)
FT3- 2.4 (Range- 2.0-4.7)
Anti-TPO ab - 234 High
I'm also taking B12 and vitamin D supplements.
Ferrittin was 67 with range of 22-322
Vit. D was 26.5 Lo
B12 was 382 range 211-911 Lo
Since you weren't feeling too good on 125 of Synthroid, I am not surprised that you feel worse on only one grain of Armour Thyroid. The Armour dose is a much lower equivalent dose than the Synthroid.
Conversion tables shows that 100 mcg of T4 = 60mg (one grain of Armour) = 25 mcg of T3, which is very confusing because that means that 25 mcg of T3 equals 100 mcg of T4, or a ratio of 4 to 1. If you then apply that ratio to the 60 mg of Armour, containing 39 mcg of T4 and 9 mcg of T3, you would get 39 + (9 times 4), which is only 75. That suggests that one grain of Armour is only equivalent to 75 mcg of T4, not 100.
So further muddle things, there is a scientific study that concluded that the ratio between T4 and T3 was only 3.3 to one, not 4 to 1. So that means that one grain of Armour is only equivalent to about 68 mcg of T4, and that your 125 dose, that wasn't adequate to relieve symptoms would be the equivalent of almost 2 grains of Armour.
If you will please post your last set of thyroid related test results and reference ranges shown on the lab report, we can help get you prepared for your next blood work, and a discussion with your doctor.
