Dr. O’Connor also co-authored the largest survey on anabolic steroid use, involving 2,385 men, published in the peer-reviewed American Journal of Men’s Health. Dr. O’Connor has over 20 years of experience treating men and women with a history of anabolic steroid, SARM, and PED use. Failure to implement an effective post-cycle therapy may also cause long-term testosterone deficiency, negatively affecting a man's well-being, libido, and fertility. Certain supplements such as TUDCA or fish oil may be beneficial; however, they will not completely negate the toxicity of Dianabol and other steroids. Harsher steroid combinations than the above can cause even higher levels of toxicity in our experience. In comparison, testosterone cypionate can be prescribed to treat hypogonadal men, and thus possession of this steroid is legal when accompanied by a prescription. In order for bodybuilders to obtain such products, someone will have to get them illegally imported. Furthermore, 25% of UGL products contained no trace of steroids (32). The reason why oral Dianabol has a much shorter half-life (3-6 hours) is because of liver metabolization, which speeds up the removal of the compound from your body. As injectable Dianabol can take longer to have an effect, users may want to increase the duration of their cycles.
