This is a really old post, but im switching from .015 levo to .015 armour. IS this not correct?
Your conversion's right. The main concern when switching to Armour is usually adrenal fatigue. If you've been tested and have AF, then you'll need to support your adrenals. If you haven't been tested, then keep an eye out for any hyper symptoms, as the combination of Armour and AF can do this.
As for when to feel results, it really depends on the individual. Some feel the effects almost immediately. Others need a couple of weeks.
Please keep us posted.
