So when starting Armour it is possible to
have a few good weeks of feel good, then then for
wear off. Usually the reason is that the initial boost is from the T3 addition, but then the crash is because the T3/T4 ratio is not optimum for your body.
I have read, taking T3 in pill form is like swallowing uppers because there's a immediate rush, and then a quick down-turn and it can have serious, adverse health consequences. I heard it called cocane of thyroid drugs.
