For the first time, Trenbolone acetate was thoroughly studied in 1967, and during a series of experiments with synthetic anabolic steroids By the beginning of the 1970s, trenbolone acetate was sold in the UK by Hoechst under the trade name Finajet and also by Roussel in France under the name of Finaject.
Chemical structure
Trenbolone has similar features as nandrolone (you know it as Deca or NPP). Both of them are the 19-nor steroids, which means that the testosterone molecule was modified at the 19th position to give people a completely new compound.
However, Trenbolone is slightly different; it is a compound for pure mass. Thus, it may help to add muscle mass with minimal fluid retention. Its anabolic activity level is 500%, while the testosterone anabolic range is only 100%.
Quick Characteristics
- Acne: yes
- Fluid retention: no
- High Blood Pressure: yes
- Hepatotoxicity: no
- Aromatase: no
- Progestogenic activity: present
- DHT (dihydrotestosterone) conversion: yes
- Decrease of HPTA function (testosterone production): yes
- Anabolic activity (500%) / androgenic activity (200%)
- Detection time - 6-7 weeks
Effects
- An increase of muscle mass (up to 10 kg, or 20 lbs for an 8-week cycle)
- Strength boost
- Increased level of IGF (by about 200%)
- Fat loss
- Increase in libido on the course duration and a significant reduction after the course (if you are not using Clomid and hCG)
- Increased cortisol level
Side effects
Most often, during the cycle of trenbolone, there is a possibility of side effects: insomnia, high blood pressure, increased aggression, acne, alopecia, increased oiliness of the skin, and others:
- Decreased libido, flaccid erection (very often during the course);
- Estrogen effects are almost always absent (no aromatization)
- The risk of unwanted reactions increases if you combine trenbolone with Clenbuterol or Ephedrine.
A toxic effect on kidneys is absent. This side effect of trenbolone is a consequence of the fact that during the course the urine may get stained red by derivable metabolites and it is mistakenly understood by some athletes as a sign of pressure on kidneys.
Trenbolone Dosage and Uses
Dosage: from 25 mg and up to 150 mg per day before a competition.
The frequency of dosing: alternate day dosing, in rare cases – daily.
An effective dosage varies from 300 to 700 mg per week. Amateurs should not inject more than 200 mg / week.

Conclusion
Trenbolone Acetate is one of the most powerful and effective anabolic steroids ever developed, renowned for producing dramatic gains in lean muscle mass and strength. However, this potency comes with a significant cost — a high risk of pronounced side effects, from insomnia and aggression to severe testosterone suppression.
