If we consider people on propeciahelp.com a small number of people having these problems we have to consider another thing which might be something crucial in our rare cases.
EQUOL
There is a group of people among all human beings capable of producing “EQUOL” a potent natural DHT systemic inhibitor that gets created within human GUT.
Yes. This rear substance gets created in some of human bodies. The whole biochemical reaction creats when you serve some types of foods together.
The natural source of EQUOL comes from the digestion process of SOY METABLISM. It means that whenever you serve soy based products, soy addictives you may metabolize it with the EQUOL by product effect.
For some humans EQUOL may be toxic, which may also be considered as soy allergic reaciton.
There are even some proves that EQUOL production gets exaggerated by the bacteria comming from dairy stuff.
What it generally means in a short conclusions.
When you consume any product with some SOY insertion, plus you consume a cow milk of any kind, there is a high propability that your GUT may create high amounts of EQUOL being able to block your DHT expression.
I really suggest you staying away from any SOY based, SOY featured product plus avoid any dairy products. You should also stay away from any phytoestrogens present in other (not soy related) natural products like any beans, bread, nuts many types of meat and all other isoflavon/phytoestrogen/flax content in it.
When you consume it plus you add the natural Equol buster (dairy), then you might be getting toxicated by that tricky digestive byproduct.
EQUOL while being produced has a long bioavailability of at least 36 hours.
