Stop the thryoid madness saved my life!
Dessicated thryoid -- can be Armour, or Westhroid or Thyroid-S or Naturethroid (there are others). Armour is dessicated thryoid but a certain brand. They are all basically the same.
The reason why multi-dosing is key is because the half life of T3 is very short. So, it peaks in about 4 hours -- and then the potency declines in the body (or lack of a more scientific explanation). Therefore, anyone who takes dessicated thyroid or T3 -- should NOT take it all at once for best results.
This does not apply to Synthroid which is a T4 only drug.
