Turinabol, also known as Tbol, Oral Turinabol, Oral Tbol, and 4-Chlorodehydromethyltestosterone, is an oral anabolic-androgenic steroid (AAS). It is a derivative of dianabol (dbol), but it does not aromatize into estrogen. In fact, it produces slow, quality gains with less side effects than methandrostenolone.

Tbol was introduced by the pharmaceutical company Jenapharm, East Germany in the 1960's. The sole goal was to get a competitive edge for both their male and female athletes in the Olympics. It was said that the success of East German Olympians from the 60's through the 80's can directly be traced to Tbol use.
The East Germans called the 'tbol' doping program STASI14.25, and it was kept secret until the 1990's when Germany was unified. In fact, it is one of the few steroids in history that was developed solely for performance enhancement purposes and not for medical use.
Currently, turinabol is marketed and sold only by UnderGround (UG) clandestine laboratories via the black market. There is no pharmaceutical or veterinarian production of this drug, and it's unlikely there will be in the near future.
Tbol vs. Dbol
Although Tbol and Dbol are almost the same thing, the difference is that there is an added 4chloro alteration with Tbol, which differentiate the two steroids. Turinabol has a zero (0) androgenic rating and a mild 53 anabolic ranking. This means there is zero androgenic or estrogenic activity with tbol (no aromatization will take place); therefore, users can expect slow, dry gains. On the other hand, dianabol is the king of aromatization and users will add a tremendous amount of mass (much of it water), in a short period of time.
Tbol is not a great bulking steroid at all, but that doesn't mean it does not have tremendous benefits in cycles. Since it does not aromatize, you don't have to worry about estrogenic side effects such as gynecomastia (bitch tits), water retention (oedema), insomnia, or high blood pressure (hypertension). No aromatase inhibitor is needed with Tbol cycles, so those who are prone to estrogen related side effects will appreciate this drug.
- Results without weight gain (this is advantageous in sports where you are trying to make weight or compete in a certain weight class)
- Tighter muscles without a puffy look
- Increase in strength
- Increase in lean muscle mass
- Ability to strongly bind to SHBG
- Increase in free testosterone
- Low-Side Effects
Unlike most other steroids, there are no medical uses for Turinabol. As mentioned above, it was produced for the sole purpose as a performance enhancer by the East Germans.
For men, I recommend 20-50mgs per day as part of a steroid stack. Many bodybuilders think they have to use it in high dosages for good results, this is false. Since Tbol does not aromatize, don't expect the scale to move daily, as you won't retain a lot of water in your muscles.
Women can run Tbol at tiny dosages, 2.5-7.5mgs per day max. It can cause virilization at higher dosages. Remember the East German women jokes? They are rooted in tbol use, so be very careful ladies.
|Male||20-50 milligrams per day|
|Female||2.5-7.5 milligrams per day|
The half-life is a whopping 16 hours, so once a day dosing will work fine. Though, I have seen numerous bodybuilders split the dosage into 12 hour intervals to get the “perfect” blood levels.
Oral-Only: Tbol and Dbol Cycle
|*Use aromasin or arimidex is dose-dependent on your response to estrogenic side effects. Exemestane at around 10mgs/EOD should be adequate.|
Oral-Only: Tbol and SARMS (MK-2866+Anabolicum)
The logic behind this cycle is very simple. Since Turinabol has a zero (0) androgenic ratings, it's recommended you use it with SARMS (selective androgen receptor modulators). Therefore, you'll be getting the anabolic effect from tbol and androgenic effect from SARMS.
Injectable: Tbol and Testosterone Cycle
|*Use of an aromatase inhibitor with this cycle is required.|
Arimidex 0.5mgs ED or Aromasin 12.5mgs ED
As with all anabolic steroids, you must run a complete post cycle therapy (PCT) with Tbol cycles. I suggest you use the perfect post cycle therapy (PCT) that's based on the evolutionary PCT model.
Tbol is 17-alpha-alkylated (17aa) to survive the first pass through the liver. You need to be very careful when stacking it with other oral steroids at moderate to high dosages due to potential kidney, liver issues. This means you must use a liver/kidney support supplement with it, such as N2Guard. I suggest sticking to a maximum two (2) orals per 6 weeks regiment and never stacking more than two (2) oral-steroids at a time. Although tbol generally has less side effects than other AAS, it should still be respected, as it is a powerful hormone.

Tbol is a great addition to a stack to get lean gains with little side effects. It is falsely considered 'weak' by some bodybuilders because it will not add a lot of weight to your frame. However, it will add amazing dry, lean gains and strength.
