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 1 mg 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 of 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 is Chlorodehydromethyltestosterone Supplied
Chlorodehydromethyltestosterone is not available as a prescription drug product. When manufactured, it was found in 1 mg and 5 mg tablets, sold in Germany/German Democratic Republic.
Structural Characteristics of Chlorodehydromethyltestosterone
Chlorodehydromethyltestosterone is not aromatized by the body, and is not measurably estrogenic. An anti-estrogen is not necessary when using this steroid, as gynecomastia should not be a concern even among sensitive individuals. Since estrogen is the usual culprit with water retention, this steroid instead produces a lean, quality look to the physique with no fear of excess subcutaneous fluid retention. This makes it a favorable steroid to use during cutting cycles, when water and fat retention are major concerns.
Chlorodehydromethyltestosterone Side Effects (Estrogenic)

An anti-estrogen is not necessary when using this steroid, as gynecomastia should not be a concern even among sensitive individuals.

This makes it a favorable steroid to use during cutting cycles, when water and fat retention are major concerns.
Chlorodehydromethyltestosterone Side Effects (Androgenic)
Although chlorodehydromethyltestosterone is classified as an anabolic steroid, androgenic side effects are still possible with this substance. These may include bouts of oily skin, acne, and body/facial hair growth. Doses higher than normally prescribed are more likely to cause such side effects. Anabolic/androgenic steroids may also aggravate male pattern hair loss. Women are additionally warned of the potential virilizing effects of anabolic/androgenic steroids. These may include a deepening of the voice, menstrual irregularities, changes in skin texture, facial hair growth, and clitoral enlargement. Chlorodehydromethyltestosterone is not extensively metabolized by the 5-alpha reductase enzyme, so its relative androgenicity is not greatly altered by the concurrent use of finasteride or dutasteride.
Chlorodehydromethyltestosterone Side Effects (Hepatotoxicity)
Chlorodehydromethyltestosterone is a c17-alpha alkylated compound. This alteration protects the drug from deactivation by the liver, allowing a very high percentage of the drug entry into the bloodstream following oral administration. C17-alpha alkylated anabolic/androgenic steroids can be hepatotoxic. Prolonged or high exposure may result in liver damage. In rare instances life-threatening dysfunction may develop. It is advisable to visit a physician periodically during each cycle to monitor liver function and overall health. Intake of c17-alpha alkylated steroids is commonly limited to 6-8 weeks, in an effort to avoid escalating liver strain. The use of a liver detoxification supplement such as Liver Stabil, Liv-52, or Essentiale Forte is advised while taking any hepatotoxic anabolic/androgenic steroids.
Chlorodehydromethyltestosterone Side Effects (Cardiovascular)
Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to reduce HDL (good) cholesterol values and increase LDL (bad) cholesterol values, which may shift the HDL to LDL balance in a direction that favors greater risk of arteriosclerosis. The relative impact of an anabolic/androgenic steroid on serum lipids is dependant on the dose, route of administration (oral vs. injectable), type of steroid (aromatizable or non-aromatizable), and level of resistance to hepatic metabolism. Chlorodehydromethyltestosterone has a strong effect on the hepatic management of cholesterol due to its non-aromatizable nature, structural resistance to liver breakdown, and route of administration. Anabolic/androgenic steroids may also adversely affect blood pressure and triglycerides, reduce endothelial relaxation, and support left ventricular hypertrophy, all potentially increasing the risk of cardiovascular disease and myocardial infarction.
To help reduce cardiovascular strain it is advised to maintain an active cardiovascular exercise program and minimize the intake of saturated fats, cholesterol, and simple carbohydrates at all times during active AAS administration. Supplementing with fish oils (4 grams per day) and a natural cholesterol/antioxidant formula such as Lipid Stabil or a product with comparable ingredients is also recommended.
Chlorodehydromethyltestosterone Side Effects (Testosterone Suppression)
All anabolic/androgenic steroids when taken in doses sufficient to promote muscle gain are expected to suppress endogenous testosterone production. Without the intervention of testosterone-stimulating substances, testosterone levels should return to normal within 1-4 months of drug secession. Note that prolonged hypogonadotrophic hypogonadism can develop secondary to steroid abuse, necessitating medical intervention.
Chlorodehydromethyltestosterone Administration (General)
Studies have shown that taking an oral anabolic steroid with food may decrease its bioavailability. This is caused by the fat-soluble nature of steroid hormones, which can allow some of the drug to dissolve with undigested dietary fat, reducing its absorption from the gastrointestinal tract. For maximum utilization, this steroid should be taken on an empty stomach.
Chlorodehydromethyltestosterone 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 pre-contest 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.
Chlorodehydromethyltestosterone 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.
Chlorodehydromethyltestosterone has been unavailable as a prescription drug product in Germany (the sole country of manufacture for most of its history) since 1994. A very small number of pharmaceutical companies have marketed the drug since, mainly in less regulated markets of Eastern Europe and Asia, where black market demand still influences production. In reviewing some of the remaining pharmaceutical products and recent changes on the global pharmaceutical market, we have made the following observations.
Balkan Pharmaceuticals (Moldova) makes the product Turanabol. It is prepared in 10 mg tablets, 20 tablets per foil and plastic strip.
Turinabol is produced by Swiss Remedies and available across Europe. Due to numerous fakes of this product, Swiss Remedies offers a convenient online product checker.
Magnus Pharmaceuticals makes the product Turinabol primarily for the EU and UK markets. Due to fake products appearing on the market, Magnus offers an online checker that lets steroid users verify their product originality.
Anabolic Steroid Guide reference
Oral-Turinabol is an oral steroid which was developed during the early 1960's.
OT has a predominantly anabolic effect which is combined with a relatively low androgenic component. On a scale of 1 to 100 the androgenic effect is very low -only a 6- and the anabolic effect is 53. (In comparison: the androgenic effect of Dianabol is 45 and its anabolic effect is 90.) Oral-Turinabol thus has milligram for milligram a lower effect than Dianabol. It is therefore not a steroid that causes a rapid gain in strength, weight, and muscle mass. Rather, the achievable results manifest themselves in a solid muscle gain and, if taken over several weeks, also in a good strength gain. The athlete will certainly not get a puffy look as is the case with Test-osterone, Dianabol, and Anadrol 50. The maximum blood concen-tration of Oral-Turinabol when taking 10, 20 or 40 mg/day is 1.5 -3.5 or 4.5 times the endogenous testosterone concentration (also see Dianabol). This clearly shows that the effectiveness of this compound strongly depends on the dosage.
0.4 x pound (body weight) x days = number of tablets to take overall during the interval of intake mg / tablet
An athlete weighing 200 pounds would take only 4 tablets of 5 mg (20mg/day.) In our experience bodybuilders take 8-10 tablets of 5 mg, that is 40-50 mg/day. Many enthusiastically report good results with this dosage: one builds a solid muscle mass, the strength gain is worthwhile seeing, the water retention is very low, and the estrogen-caused side effects are rare. Not without good reason OT is also popular among powerlifters and weightlifters who appreciate these characteristics.
Due to its characteristics OT is also a suitable steroid both for men and women in competitions. A usually very effective stack for male bodybuilders consists of 50 mg OT/day, 228 mg Parabolan/week, and 150 mg Winstrol Depot/week. Those who have brought their body fat content to a low level by dieting and/or by using fatburning substances (e.g. Clenbuterol, Ephedrine, Salbutamol, Cytomel, Triacana), will find that the above steroid combination will manifest itself in hard, sharply-defined but still dense and full muscles. No enlarged breasts, no estrogen surplus, and no watery, puffy-look-ing muscle system. If OT were available on the U.S. black market for steroids, bodybuilders, powerlifters, and weightlifters would go crazy for this East German anabolic.
OT enjoys a great popularity since it is quickly broken down by the body and the metabolites are excreted relatively quickly through the urine. The often-posed question regarding how many days before a test OT can be taken in order to be "clean" is difficult to answer specifically or in general. We know from a reli-able source that athletes who only take OT as a steroid and who, in part, take dosages of 10- 15 tablets/day, have discontinued the com-pound exactly five days before a doping test and tested negative. These indications are supported by the fact that even positive urine analyses have rarely mentioned the names Oral-Turinabol or chlordehydromethyl-testosterone.
The potential side effects of OT usually depend on the dosage level and are gender-specific. in women, depending on their predisposi-tion, the usual virilization symptoms occur and increase when dos-ages of more than 20 mg per day are taken over a prolonged time. In men the already discussed reduced testosterone production can rarely be avoided. Gynecomastia occurs rarely with OT Since the response of the water and electrolyte household is not overly dis-tinct athletes only rarely report water retention and high blood pressure. Acne, gastrointestinal pain, and uncontrolled aggressive behavior are also the exception rather than the rule with OT An increased libido is reported in most cases by both sexes. Since the substance chlordehydromethyltestosterone is I 7-alpha alkylated the manufacturer in its package insert recommends that the liver func-tion be checked regularly since it can be negatively affected by high dosages and the risk of possible liver damage cannot be excluded. Thus OT is also a steroid that can be taken without interruption for long intervals. Studies of male athletes who over a period of six weeks were given 10 mg OT/day did not show any indications of health-threatening effects.
The availability of OT is extremely poor. There is no chance finding an original Oral-Turinabol tablet in the U.S.
