As a non-aromatizing androgen, dihydrotestosterone is extremely potent. Aromatization refers to the conversion of testosterone or anabolic steroids into estrogen. High estrogenic activity causes bloating, acne, water retention and oily skin. As dihydrotestosterone does not aromatize even at high dosages, users do not face the aforementioned side-effects. Lack of water retention also has a hardening effect on muscle tissue, in bodybuilders. Being a powerful androgen, dihydrotestosterone is also responsible for a shift in the estrogen-testosterone ratio in the body. Due to its predominant androgenic component, the steroid has a stimulating effect on the adreno-pituitary functions, and causes neurological excitation in the ‘sexual orientation areas of the brain’. This in turn, spikes sex drive in males.
This is an antibiotic that has figured prominently in recent news items about cases of Duchenne due to premature "stop codons." In these cases the complete gene for dystrophin is never "decoded" or translated so that this critical muscle protein is not made, or at least not made in full form. Research on mdx mice that simulate human Duchenne has shown that when gentamycin is administered, the premature stop codon is somehow ignored so that the entire gene transcript can be "read" and dystrophin can be produced. A preliminary trial on Duchenne young men is underway, and hopes are high that this will work in humans as well as it did in the model mice. Unfortunately, this treatment would only work for those instances (about 10% of all Duchenne cases) in which the gene defect is a premature stop codon.
