The normal range for TSH is 0.5 to 5.5., so since you're borderline, thyroxine may be too much for you right now. Armour might be better, or just some skin food and iodine. When you get the liver clean the thyroid should equalize. If you were more symptomatic I'd say take it, but since you're not, best not do that strong of an intervention, because being hyPER thyroid is really annoying! ;/
white and red? hmmm... could be a parasite nest. if the red looked like veins...then definitely parasites. You can store things in your colon for years, so don't look to recent meals to explain why this came out of you! :)
