Trenbolone is a highly potent injectable anabolic steroid, renowned for being one of the most powerful drugs available. Although it is not as harsh as sometimes depicted, it is definitely not recommended for beginners. Trenbolone is typically used by advanced athletes experienced with steroid use. It is a derivative of Nandrolone, part of the 19-nor (19-nortestosterone) group of anabolic steroids, characterized by a distinct molecular structure that enhances its stability and resistance to metabolic breakdown in the body.

Trenbolone's unique structure allows it to form a strong bond with androgen receptors, making it exceptionally effective. This high potency means that impressive results can be achieved with relatively small doses, providing a shortcut to the desired effects.

Trenbolone exhibits both androgenic and anabolic activity, with an index of 500, which is five times stronger than Testosterone (index 100). For context, 200 mg of Trenbolone is equivalent to 1000 mg of Testosterone, and 500 mg is equivalent to 2500 mg.

This steroid is known for promoting significant muscle growth without causing water retention, due to its lack of aromatization (conversion into estrogen). Additionally, Trenbolone stimulates the production of insulin-like growth factor 1 (IGF-1) in muscle tissues.

Currently, Trenbolone is legally used as a veterinary drug to stimulate cattle growth. It remains of interest to the medical community but has not yet received FDA approval for human use.

Metabolically, Trenbolone is resistant to the aromatase enzyme, preventing its conversion to estrogen. It also resists the enzyme 5-alpha reductase, which converts Testosterone to the more potent androgen Dihydrotestosterone (DHT), meaning Trenbolone cannot be converted to DHT.

Trenbolone cycles are highly effective for both fat burning and muscle building. The drug binds to catabolic hormone receptors, blocking their signaling to muscle cells, which is crucial for counteracting the catabolic hormone cortisol that inhibits muscle growth. Trenbolone's anti-catabolic properties reduce the negative effects of catabolism, shortening diet and competition training programs. It is also known for its cutting properties by activating androgen receptors in fat cells, promoting fat burning. Furthermore, Trenbolone retains nitrogen in muscle tissue, essential for maintaining mass and volume.


  • Rapid muscle growth
  • Fat burning
  • Increased strength

Side Effects

  • Suppression of testicular function
  • Sleep problems
  • Negative mood
  • Increase in prolactin levels


Trenbolone dosages vary widely, from 150 mg to 800 mg per week, with most average doses between 200 mg and 600 mg per week. It is designed to maintain an even, prolonged concentration in the blood, accelerating the onset of effects and extending the half-life. The drug is typically administered 1-2 times per week.
