Turinabol (Tbol)

Turinabol (4-Chlorodehydromethyltestosterone) is essentially a modified form of Dianabol. It is colloquially known as "Tbol".

Historically significant, it was the secret weapon of the East German doping machine (State Plan 14.25) in the 1960s and 70s. It was designed to separate the anabolic effect from the androgenic effect, allowing female athletes to use it with lower risk of virilization (though risks remained).

Quick Specs

Mechanism of Action

Structurally, Turinabol is Dianabol with an added chlorine atom at the 4th carbon position. This simple change accomplishes two major things:

1. Prevents Aromatization: It makes the molecule impossible for the aromatase enzyme to convert into estrogen.
2. Lowers Androgenicity: It reduces the interaction with the 5-alpha reductase enzyme.

The result is a steroid that builds muscle like a mild Dianabol but without the water retention or estrogenic side effects.

Pharmacokinetics & Dosing

Half-Life: ~16 Hours

Tbol has a relatively long half-life for an oral steroid.

• Dosing: Because of the 16-hour half-life, some users take it once daily, though splitting it into two doses (AM/PM) ensures perfectly stable blood levels.

Primary Effects

1. Slow, Lean Gains

You will not blow up 10lbs in a week on Tbol. Gains are steady, dry, and sustainable. It is often compared to Anavar in terms of the "quality" of muscle gained.

2. Athletic Performance

Tbol increases strength and endurance without significant weight gain, making it ideal for athletes who need to stay in a weight class or maintain speed.

3. Increased Free Testosterone

Like Winstrol and Proviron, Turinabol binds weakly to SHBG, potentially freeing up more circulating testosterone.

Side Effects & Harm Reduction

1. Hepatotoxicity

It is C-17 alpha-alkylated and liver toxic. While generally tolerated better than Anadrol or Superdrol, it can still elevate enzymes significantly.

• Management: Limit use to 6-8 weeks. Use liver support.

2. Lipid Strain

Like all oral steroids, it suppresses HDL cholesterol and raises LDL, increasing cardiovascular risk over time.

3. Back Pumps

Painful lower back pumps are a frequently reported side effect, likely due to increased kidney stress or fluid shifts.

• Management: Taurine (3-5g) and high water intake.

Tracking Turinabol

Using the Anabolic Tracker app:

1. Inventory: Add Turinabol.
2. Scheduling: Daily or Twice Daily.
3. Metrics: Monitor Body Weight. Unlike Dbol, weight should go up slowly. Rapid jumps may indicate diet issues rather than drug effects.
4. Bloodwork: Pay close attention to Lipids (HDL/LDL) on your next blood test.
