Oral-Turinabol. Active: chlorodehydromethyltestosterone
They developed the oral steroid Oral-Turinabol during the early 1960s. Introduced on the market by the former GDR. Next to its clinical application it was the number one doping drug of the GDR. In the West, few insiders knew about this anabolic steroid. Mostly from the powerlifting and weightlifting scene.
Oral-Turinabol 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 rapid gain in strength, weight, and muscle mass. Rather, the achievable results manifest themselves in a solid muscle gain and when taken over several weeks, also in a good strength gain. The athlete will certainly not get a puffy look as is the case with Testosterone, Dianabol, and Anadrol 50. The maximum blood concentration 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.
The success formula of the GDR (from Doping — Von der Forschung zum Betrug, page 142, Brigitte Berendonk) is:
0.4 x pound (body weight) x days divided by mg/tab = number of tablets to take mg / tablet overall during the interval of intake.
This might not be sufficient in the minds of bodybuilders. Based on this formula 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. We know two athletes who in certain phases of their training take 20 tablets of 5mg daily, are massive and muscular and are able to bench press more than 450 pounds and squat over 650 pounds. Mind you, this is without additional intake of other steroids.
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 fat-burning 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 looking muscle system.
For a large number of athletes successfully circumvented testosterone reduction. After only five days after discontinuance, levels normalised. Then continued to increase even further. It is interesting that the production of the body’s own testosterone only one week after discontinuance can be above the initial value before medication. In addition, researchers noted that it maintains the increased testosterone level over 8-10 days. Regarding doping tests, do not undervalue the possible rebound effect. The reason for the relatively quick rebound of the body’s own testosterone level could be that, compared to other steroids, OT reduces the testosterone level ”only” to 60-70% of its normal value while, for example, with the considerably more androgenic Dianabol this level decreases to 30-40% of its normal value.
R.Héicker, B. Bernstein, and G. Rademacher discovered an interesting aspect during their study “Pharmakokinetische Vergleichsuntersuchung Von Oral-Turinabol und Dianabol.” 20 mg Dianabol/ day reduces the cortisone concentration in the blood after five days of intake by 50% and on the 15th day of intake it is even 74% lower compared to the initial level. With an intake of 20 mg OT/day, however, no significant suppression of the endogenic cortisone concentration was noticed. This might also be one of the reasons why administration of Dianabol usually results in faster and more drastic progress with respect to a gain in strength, weight, and possibly an improved regeneration, whereas the growth rates with Oral-Turinabol were slower and more even.
Effects on testosterone production
The body’s own testosterone production with OT does not decrease too much so that after its discontinuance it is quickly normalized. These are probably reasons why athletes, after discontinuing Oral-Turinabol tablets do not experience a dramatic performance breakdown. As is often the case with Dianabol. The organism reacts to the reduced cortisone production caused by Dianabol with a rebound effect. Meaning the cortisone production exceeds the normal measure. The result is that the cortisone molecules will form a receptor-molecules in muscle cells. Forcing the muscle cell to break down protein. With Oral-Turinabol there is no such cortisone-rebound effect.
The substance chlorodehydromethyltestosterone reaches its maximum concentration in the blood 1 to 3 hours after intake. The half-life time of OT is between 6.9 and 7.2 hours (The half-life time is an exponential decay law that describes the period which the body needs for half of the substance to be converted.). It is logical not to take the daily amount of tablets at once. 3-4 divided doses daily guarantees a constant concentration in the blood. According to exponential decay law, 72 hours after use of OT no anabolic equivalents is found in the blood (not in urine!). Thus, exactly three days after they complete the intake cycle of Oral-Turinabol, the tablets are no longer effective.
Athletes also noted a higher training motivation among those tested. Oral-Turinabol activates the central nervous system through the bonding of the substance molecules with the steroid receptors in the brain. The East German research studies also mentioned that OT, together with an intense resistance training, helps to enforce the buildup of strength and muscles: with OT the resting urine value can also be considerably lowered which conﬁrms the protein-anabolic effect of this remedy.
OT stimulates the biosynthesis (formation) of cell proteins in the entire human organism.
The potential side effects of OT usually depend on the dosage level and are gender specific. In women, depending on their predisposition, the usual virilization symptoms occur. Especially with increased doses of over 20 mg per day, taken over a prolonged time. In men, avoiding reduced testosterone production is rare. Gynecomastia occurs rarely with OT. Water and electrolyte retention is not distinct. Athletes only rarely report water retention and high blood pressure. Acne, gastrointestinal pain, and uncontrolled aggressive behavior are the exception rather than the rule with OT. Athletes report increased libido in both sexes. Since the substance chlorodehydromethyltestosterone is a 17-alpha alkylated the manufacturers package insert recommends checking liver function regularly. High dosages can affect it. They cannot exclude risk of liver damage.
Thus OT is also a steroid that can be taken without interruption for long intervals. Studies of male athletes given 10 mg OT/day over a period of six weeks did not indicate health-threatening effects. “Condition: The regularly recorded clinical and para-clinical diagnoses over the entire observation period showed no striking findings deviating from the norm.” (from Hormonelle Regulation und psychophysische Belastung im Leistungssport by R. Hacker and H. de Marees.)
