Vitamin D: gives great results in the gym but destroys my libido. From what I know this is an aromatase inhibitor.
Zinc: decent results from working out. Once again, destroys my libido. I understand this can inhibit aromatase but also lower DHT?
Magnesium : good result in the gym, but ruins my libido and also causes shrinkage downstairs. Not sure why on this one. I've never read that it affects DHT or aromatase. It remains a mystery.
Vitamin K: this includes supplementation and from vegetables like kale. Both kill my libido. I think this is a known aromatase inhibitor.
Do we have the same physiological make up!??! Everything you listed here is the same as me.
Do you have LOW iron by any chance?
