Characteristics

ATD is a steroidal aromatase inhibitor, known as a suicidal inhibitor because it permanently binds to the aromatase enzyme.

ATD is used for its aromatase inhibiting and testosterone boosting effect. Its effectiveness at lowering estrogen appears to be stronger than 6-oxo. It converts to 1,4,6-testosterone, which would also be expected to cause falsely high readings for a testosterone analysis.

The 1,4,6-testosterone metabolite of ATD can also bind to the androgen receptor (AR) and induce androgenic (or possibly anti-androgenic) effects similar to what is seen from 6-oxo. This would be expected since 1,4,6-testosterone has about one third the binding affinity for the AR, therefore it may interefere with the anabolic or androgenic action of hormones which bind the androgen receptor.

ATD would also be expected to interfere with production of natural testosterone by acting upon the hypothalamus pituitary testicular axis (HPTA), therefore this compound should not be used during post cycle therapy (PCT), however it could successfully be used during a cycle to help keep estrogen in control. Anecdotal reports and animal studies have also shown ATD inhibits libido and general sexual potency.
