Users have reported pretty strong suppression of natural testosterone levels while using Oral Turinabol. This steroid is liver toxic but likely only slightly more toxic than equal doses of methandrostenolone. This steroid is well-known for its role in the state-sponsored doping program of the former East German Olympic doping program. This drug was given to male and female athletes specifically to increase athletic performance in the Olympics. Though men were also treated, women were the focus because they responded much better to treatment. Doses of only 10 to 20 mg per day produced marked increases in performance in women. This program also included other drugs like mestanolone, the 11-beta hydroxy form of Oral Turinabol, 4-chloro-methyltestosterone, 4-chloro-mestanolone, methandrostenolone, testosterone and nandrolone esters as well as some stimulants and peptide hormones. Even so, Oral Turinabol was the focus because it seemed to report the best results 4 .
Negative cardiovascular risks , side effects, and cholesterol changes are a known side effect shared by all anabolic steroids, and this side effect does apply to Turinabol side effects. Negative cardiovascular side effects resultant from anabolic steroid use involves the reduction of HDL (the good cholesterol) and increases of LDL (the bad cholesterol ). The result of such changes involves an increased risk of arteriosclerosis, and the degree to which these changes occur for the worse are usually dose-dependent (with higher doses increasing the negative changes and the risks). Other factors that affect these negative cholesterol changes are: duration of use, and route of administration. In terms of the route of administration, oral anabolic steroids are known for having a reputation as being much worse for their negative impacts on cholesterol in comparison to injectable anabolic steroids. This is because the liver serves to function as the cholesterol processing center for the human body, and the increased hepatotoxicity associated with anabolic steroids will result in even worse negative cholesterol changes.
