Let's first look elsewhere at another mechanism where we have an insulin rise after a workout from recovery drinks causing a DECREASE in blood levels of Testosterone.
Does that mean that the drink or workout is causing LOWER testosterone levels?
Hell NO! The insulin causes the T to clear from the blood faster after the workout and the very same could be true of the supposed drop in I with anastrozol use above!
Damn if it doesn't look like we can throw a lot of animal studies out as it's not so much contradictory about what hormone does what but it is well known that T causes a rise in H and T and T3 and H are closely related, too, so to say that 'androgens in animals' caused a lowering or rising of one thing or another CANNOT be extrapolated to humans.
So we don't know if the I is being used better or not, but it seems that IT MOST CERTAINLY IS because if H is the same, and I is going down in the blood, is the H not being converted to I any longer by the liver? I would say SAID scenario is not the case plainly if nothing more than because more H floating around would cause a REDUCTION in H production and we didn't see that, either.
And anyone will tell you that certain hormones make you incredibly hungry and when they try I, they found the same 'hunger'.
