But, when dosed too high, like in many products (over about 20mg per day), it can cause some loss of sex drive due to its binding to the androgen receptor in the brain.  This ingredient is often promoted to “increase wood” but actually it has the opposite effect in doses above a certain threshold.  ATD has a place in AI’s at very low levels and it a good product combined with other estrogen control products.  ATD can cause a positive test for the anabolic steroid Boldenone and the prohormone Boldione, making it a bad choice for people who get drug tested.  ATD certainly is a great ingredient to include as part of your post cycle therapy or alone to boost testosterone.  The major drawback to this steroidal aromatase inhibitor is that it can blunt sex drive (which is the opposite of how it’s advertised).
