questions about thyrotropin alfa

[merry xmas]

Let's start with these simple ?s:
-doesn't anyone know if thyrotropin might be employed in anti-aging purposes? (it releases own T4 secretion)
-why is Thyrogen thyrotropin produced by chinease hamsters ovary cells whilst the most thyrotropin in the world is produced by by cattle pituitary?
-couldnìt Thyrogen cause the mortal Cruetzfeild-Jacob disease or just cattle thyrotropin does? (it's a matter of priones,i assume)
