What labs to use for exams?

I would like to know if you are aware of any cheap labs.

I saw once a user posting here a cheap and trustable german lab where I could get my Vitamin D tested for 15€, opposed to the 65€ in my country (Portugal), and I could do it at a distance…but I seem to have lost that thread.

I want to test:
Vit D
Homocysteine
Glutathione
Folic Acid/Folinic Acid
B12
24 hour Cortisol, CRH and ACTHC
PSA
Estrogen/Test ratio
C Reactive Protein
3-A-Diol G
