" Due to the 4-chloro alteration, Oral Turinabol can't interact with the aromatase enzyme, so estrogenic side effects are diminished. However, it is interesting to note that some users report mild gynecomastia with oral turinabol alone. Whether this is due to the aromatization of a small amount of methyltestosterone left over from the manufacturing process or Oral Turinabol possibly having a small amount of direct action at the estrogen receptor is unclear. The 4-chloro alteration also prevents Oral Turinabol from interacting with the 5-alpha reductase enzyme, so conversion to a dihydro form is not possible. Even so, androgenic alopecia is still possible with higher doses eg (>40 mg/day), and not surprisingly, some erectile dysfunction will be present when Oral Turinabol is used alone despite a functional sex drive. Although mild acne, gas, indigestion, elevated liver enzymes, diminished production of leutinizing hormone, and natural testosterone are all worth noting, the most serious concern is the effect it has on the blood lipid profile."
