i think the poster is genuine, however munching on tyrosine is a recipe for disaster if your adrenals are primary in the illness. it sounds to me like the thyroid was primary in her case, and thus feeding the thyroid what it likes made everything warm and fuzzy.
the iherb reference didn't sound like a sales pitch. that company does not need halfwit forum trolls to help them out, they are doing quite well.
don't penalize the person for posting once. is it better to post a million times and still be ill?
i went down the tyrosine route many years ago, and it gave me an initial lift but ultimately did nothing for me and possibly caused harm by stressing the adrenals.
and you don't need to buy fractionated aminos anyway, all you have to do is eat the proper foods or improve your digestion in order to absorb what you need.
