1-Androstenediol, commonly known as 1AD, may appear under the nomenclature 1-androsten-3b, 17b-diol. 1AD was among the first prohormones released, and was one of the first to give truly substantial gains in size and strength without the pronounced estrogenic side effects of many other prohormones like androstenediol (“andro”). 1AD converts to 1-testosterone in one step. The conversion rate when 1AD is taken orally is believed to be in the range of 10-15%, but the actual conversion rate is dependent on the individual.
1AD does not convert to estrogen and neither does 1-testosterone. This compound should not produce bloating or the estrogenic side effects typically associated with other prohormones like androstenediol such as gynecomastia. This makes 1-AD good for use during a cutting cycle, but it is also strong enough to use as a strength and mass builder during a bulking phase. 1AD is not methylated, so it does not stress the liver in the same way that many other prohormones do. Some possible side effects of 1AD use are lethargy and loss of libido. These side effects are typical with the use of steroids such as 1-testosterone and M1T, so it comes as no surprise that 1AD can also have the same effect. Not all users experience these side effects, and many that do find that adding in a moderate dose of DHEA can resolve this issue. As with other prohormones, androgenic side effects such as acne and hair loss are possible with 1AD. Overall, the side effects of this prohormone seem to be mild and well tolerated in most users.
Typical dosage of 1AD is fairly high, with many users taking 800 mg or more per day in divided doses. 1AD is not methylated, so taking it with a fat containing meal may be a good idea to increase absorption.
1AD was included in the Anabolic Steroid Control Act of 2004, and was banned as of January 20th, 2005. 1AD is no longer available, but 1-DHEA (1-androsterone), which requires a 2-step conversion to 1-testosterone is currently legal and available over the counter.
