The replacement dosage for 120 mg Armour is 200 mcg levo. If you want to
use Cytomel along with it, you can, but you have to drop the dose of levo to compensate for the Cytomel. For every 25 mcg of levo you drop, you add in approximately 5 mcg of Cytomel. So, your 200 mcg of levo went to 150 mcg, and you should have added 10-12.5 mcg Cytomel. Cytomel is about four times more powerful than levo. You can't just lower the levo and add in the same amount of Cytomel.
