The strong anabolic properties of 1-testosterone have been established in the literature. Research conducted in the 60’s found that 1-testosterone had a myotrophic (anabolic) potency of 200 as compared to 26 for testosterone, making it over 7 times as anabolic. This was done using the rat levator ani assay, which is commonly used to test the anabolic potency of steroids. In addition to this, 1-testosterone and 1-AD are both unable to aromatize to estrogen. Hence these substances cause very significant increases in muscle size and strength with about the androgenic potential of testosterone and almost no estrogenic side effects (water retention, fat gain, gynecomastia).
