because ADT = Androsterone.
Which is inside T-911.
From the product write-up
The next phase of T-911 is about reducing estrogen and giving you another pathway to both boost testosterone. Androsterone is a natural metabolite in the body that reduces estrogen which increases testosterone and may reduce aromatase (that nasty enzyme that turns your hard earned testosterone into UGLY estrogen). It also is a 5a Reduced androgen, which as a class have suggested to be potent neuro-stimulants. Neuro-stimulants don't get you wired, they make you more alert, aggressive and intense. So, Androsterone suggests that it can reduce aromatase and increase mental intensity.
