That's true, Andriol mechanism isn't the same as other orals even non 17AA orals which do not works and require higher dosage.
Andriol passes the liver via the lymphatic system and therefor it will be active critically active in very small amount of users curretnly less than 10% and that's proved
on the other hand, Andriol passes through the gut to reach the lymphatic system about about 70% is converted to DHT which cause hair loss, prostate problems According to Dan Duchaine
in my opinion Andriol is just nothing more than a waste of money
