Products of this category are an efficient orally-administered alternative for hardly-available injectable steroids based on testosterone. 1-AD (1-androstene-3b-ol-17-one) and 4-AD (4-androstene-3b-ol-17-one) are anabolic-androgenic substances and prohormones whose use results in faster development of good-quality muscle mass as well as an increase in muscle strength and endurance.

Both derivatives are characterised by more powerful anabolic properties than testosterone, and thanks to significant differences in their chemical structure, they are also resistant to transformations catalysed by aromatase. Interestingly, both 1-AD and 4-AD as well as their metabolites are poor substrates for 5-α-reductase as well, which reduces their transformations to DHT. Thanks to that, 1-AD and 4-AD supplementation has a low likelihood of negative side effects, such as water retention, the development of gynecomastia, acne, hair loss, or an enlarged prostate.
