Turinabol is the brand name for the anabolic steroid 4-chlorodehydromethyltestosterone, and is colloquially known as T-bol, Tbol, or Oral Turinabol. There are a few myths and misconceptions surrounding this compound due to the fact that Turinabol itself had its beginnings as a very mystic and rare anabolic steroid that appeared quite later than most other compounds in the performance enhancing drug world. Turinabol has commonly been touted as an “oral Trenbolone”, a “DHT derivative”, and a “mild Dianabol”. Neither of these statements are true, and the latter statement (that it is a ‘mild Dbol’) is perhaps a half-truth more than anything. As with any anabolic steroid that has its beginnings shrouded in lore and mysticism, the truth is always very different. In a sense, Turinabol is a modification of Dianabol. Turinabol is actually an amalgamation of two anabolic steroids, Clostebol and Dianabol. Clostebol, also known as 4-methyltestosterone, contains what is known as a 4-chloro group. This 4-chloro group that characterizes Clostebol, was then added to the chemical structure of Dianabol in the same position as it was on the Clostebol structure. Thus, the end result is 4-chlorodehydromethyltestosterone, or Turinabol. Its modifications provide it with some unique properties and characteristics.
Turinabol, although it is not a Dihydrotestosterone derivative, is unable to aromatize into Estrogen. The aromatase enzyme, which is the enzyme that actively converts androgens into estrogens, cannot recognize the Turinabol molecule as an appropriate substrate due to its 4-chloro substitution. This makes Turinabol one of the few anabolic steroids that is not a DHT-derivative that is unable to aromatize into Estrogen. Its differences in the chemical structure compared to other anabolic steroids also result in an extremely low androgenic profile rating, but also considerably reduces its anabolic rating as well. The end result is an anabolic:androgenic ratio of 54:6 for Turinabol. By comparison, Testosterone’s anabolic:androgenic ratio is 100:100, and we can definitely see the stark differences in its strengths, properties, and capabilities in comparison with Testosterone. Turinabol is a compound that is rare among anabolic steroids for its ability to possess a distinct difference in its androgenic and anabolic capabilities and effects / side effects. Only a couple of other anabolic steroids can really be compared on the same level to Turinabol, and those would perhaps be Primobolan and Anavar (Oxandrolone). Both of these anabolic steroids exhibit very similar properties, although Anavar is much stronger than the other two. Hence, Turinabol inherited the nickname of a ‘mild Dianabol’ due to its mild anabolic capabilities as well as its very mild androgenic capabilities as well.
It was not until 1962 when Turinabol was first developed, and was utilized medically for many purposes in a very wide range of patient types due to its unique and well-tolerated properties and effects. However, it did not enter the athletic scene until approximately 1972, and did not enter the bodybuilding scene until much later (circa the late 1980s). Even among its first use in the athletic scene in 1972, it was in secret, which was the key to its success. Turinabol was developed and manufactured by Jenapharm in East Germany. Aside from its medical use, the East German government initiated a state-sponsored doping program designed to administer anabolic steroids to their Olympic athletes both with and without the athlete’s knowledge or consent. In doing so, Turinabol, which was a closely held secret at the time, would be utilized by East German Olympic athletes that would then pass the IOC drug testing procedures due to the fact that they had been using a then-unknown and therefore then-undetectable anabolic steroid at the time, Turinabol. Word of Turinabol eventually spread into the bodybuilding circles in the late 1980s, but it spread very slowly and quietly. It was not until 1990 that the news of Turinabol, its application, use, and the fact that it was a well-kept secret of the East German government was blasted out into the public’s eyes for all to know.
The bodybuilding community’s curiosity of Turinabol and its urge to obtain it became much greater following the fall of the Berlin Wall in 1990, which was the reason for the publicizing of East Germany’s details regarding Turinabol had occurred. Its availability was quite limited, however, as Jenapharm was the only company manufacturing it at the time, and in 1994 Jenapharm ceased manufacture of it due to the massive amount of stigma and hysteria in regards to anabolic steroids at the time in the early 1990s. Today there is no Turinabol currently in production, and as consequence it is exclusively an underground product manufactured by underground labs. Turinabol is a more expensive anabolic steroid than most others, and is reserved for use by bodybuilders during periods of cutting and/or pre-contest preparation. More individuals use and have experience with Turinabol today than ever before due to its wide availability as an underground product, and there is more experienced-based anecdotal information to go by as a result.
