Protodioscin is the main saponin in the tribulus terrestris.
protodioscin achieves this primarily through causing an increase in androgen receptor immunoreacivity, meaning it increases the concentration of androgen receptors in cells, causing the organism to become more sensitive to androgens like testosterone and DHT.
This mean that when i took tribulus, i increased immunoreacivity to androgen, so my immune system started to fight my androgens.
The theory about PFS like autoimmune disiese is not BS.
This would also explain why when I tried testosterone gel, I had a steady further deterioration.
