Chlorodehydromethyltestosterone (also known as Turinabol) was created by the East German pharmaceutical company Jenapharm for use by Olympic and national-level athletes. It was patented in 1961. Oral Turinabol became an infamous steroid during the 1990s when it was revealed that chlorodehydromethyltestosterone was one of the best-kept secrets of the “East German doping machine.” Due to its structural alteration compared to Dianabol, Turinabol does not aromatize and has low androgenic properties. Like any alkylated oral steroid, Turinabol negatively affects blood cholesterol levels (though not as much as stanozolol). It also reduces sex hormone-binding globulin (SHBG) and, as a result, increases the level of biologically active free testosterone in the blood. This explains the high synergistic effect when Turinabol is used in combination with other steroids, such as testosterone. Although Turinabol is sometimes considered a relatively weak drug, it inhibits the hypothalamic-pituitary-testicular (HPT) axis and suppresses endogenous testosterone production. Therefore, post-cycle therapy (PCT) with anti-estrogens is necessary for the fastest possible recovery of the endocrine system and to maintain the results obtained during the cycle. In general, Turinabol can be described as a milder analog of methandienone, without aromatization or water retention.
WARNING: Due to its C17-alpha alkylation, Turinabol may cause liver stress. Therefore, adopting a healthy lifestyle and using supplements to promote liver health is recommended. The total recommended duration of a Turinabol cycle should not exceed 6 to 8 weeks.
