Oral Turinabol (4-chlorodehydromethyltestosterone)
Androgenic no data available
Anabolic >100
Standard Methyltestosterone (oraI)
Chemical Name 4-chloro-17a-methyl-17bhydroxyandrosta-1,4-dien-3-one
Estrogenic Activity none Progestational Activity no data available (low)
Description:
Chlorodehydromethyltestosterone is a potent derivative of Dianabol. This oral steroid is structurally a cross between methandrostenolone and clostebol (4-chlorotestosterone), having the same base structure as Dianabol with the added 4-chloro alteration of clostebol. This alteration makes chlorodehydromethyltestosterone a milder cousin of Dianabol, the new steroid displaying no estrogenic and a much less androgenic activity in comparison to its more famous counterpart. The anabolic activity of chlorodehydromethyltestosterone is somewhat lower than that of Dianabol as well, but it does maintain a much more favorable balance of anabolic to androgenic effect. This means that at any given level of muscle-building activity, chlorodehydromethyltestosterone will be less likely to produce androgenic side effects.
History:
Chlorodehydromethyltestosterone was first described in 1962. Jenapharm (Jena, Germany) soon after released the drug for sale in the East German prescription drug market, under the brand name Oral Turinabol. The drug was favored by clinicians for its highly anabolic and low anabolic nature, lending .itself to use in not only adult males, but women and children as well. The product was manufactured in two strengths, containing 1mg and 5 mg of drug per tablet, so that a lower-dosed version was available for the more sensitive populations. Chlorodehydromethyltestosterone was applied for a number of medical uses; mainly those focusing on the building or preservation of lean muscle tissue and bone mass.
Oral Turinabol became a steroid of infamy during the 1990's, when it was revealed that chlorodehydromethyltestosterone had been one of the closely held secrets inside the "East German Doping Machine." This is referring to the state-sponsored doping program, called "State Plan Research Theme 14.25," that operated in East Germany between 1974 and 1989. It was an aggressive anabolic steroid administration program, designed with one goal in mind: cheating the Olympic drug test. In many cases, the Olympic athletes, both male and female, were unwitting participants, simply told by their trainers and coaches that they were being given "vitamins." Many of these blue vitamins turned out to be Oral Turinabol, a potent and undetectable (at the time) anabolic steroid. As many as 10,000 athletes were given anabolic steroids during the time the program was active, many of them taking Oral Turinabol. For a more in-depth look at this dramatic historic event, including the trials of several former East German officials for their participation, I recommend you look at the book"Faust's Gold: Inside the East German Doping Machine" by Steven Ungerleider.
In spite of an arguably favorable profile of activity and safety record, Jenapharm discontinued Oral Turinabol in 1994. This was at a time when a great deal of negative attention was being given to sports doping, lending credibility to the speculation that this decision was one based on public relations, and not necessarily finances or health concerns over the drug. Regardless,Jenapharm was acquired by Schering AG (Germany) in 1996, a company with no interest in reliving the controversies of the past (Schering had already discontinued many of its controversial anabolic steroid products as well). Before or since, no other brand 0f chlorodehydromethyltestosterone has existed as a prescription drug product. Today, this agent is still available, but is only produced by a small number of underground manufacturers and export-only suppliers.
How Supplied:
Chlorodehydromethyltestosterone is not available as a prescription drug product. When manufactured, it was found in 1mg and 5 mg tablets, sold in Germany/German Democratic Republic.
Structural Characteristics:
Chlorodehydromethyltestosterone is a modified form of testosterone. It differs by: 1) the addition of a methyl group at carbon 17-alpha, which helps protect the hormone during oral administration, 2) the introduction of a double bond between carbons 1 and 2 (l-ene), which shifts the anabolic to androgenic ratio in favor of the former, and 3) the attachment of a chloro group at carbon 4, which inhibits steroid aromatization and reduces relative androgenicity.
Administration (Men):
A common clinical dose of chlorodehydromethyltestosterone is estimated to be 5 mg per day; actual prescribing guidelines are unavailable. In the athletic arena, an effective oral daily dosage falls in the range of 15-40 mg, taken in cycles lasting no more than 6-8 weeks to minimize hepatotoxicity. This level is sufficient for measurable increases in lean muscle mass and strength. This agent is most often applied as a precontest or cutting steroid for bodybuilding purposes, and is not viewed as an ideal bulking agent due to its lack of estrogenicity. Athletes in sports where speed tends to be a primary focus also find strong favor in chlorodehydromethyltestosterone, obtaining a strong anabolic benefit without having to carry around any extra water or fat weight.
Administration (Women):
A common clinical dose of chlorodehydromethyltestosterone is estimated to be 1
2.5 mg per day; actual prescribing guidelines are unavailable. In the athletic arena, women would commonly take a single 5 mg tablet per day, taken in cycles lasting no more than 4-6 weeks to minimize hepatotoxicity. Virilizing effects are unlikely at this level of use. Much higher doses were often used with female athletes in the former GDR doping program, but often to detriment of strong virilizing side effects.
