Oh. 1 piece of advice on what not to do; don’t only take “a little armour.” It’s probably the worst thing you can do. t3 is strongly suppressive of tsh. If you do decide to take armour at all, if you’re reasonably healthy, start at a grain and don’t go below.
less than a grain may lead to less thyroid signalling overall, while any amount of t4 tends to just add a bit on top, or at least doesn’t seem to decrease the overall output as much as the amount added, so you should end up with more.
