Trenbolone Enanthate
💉 What Is Trenbolone Enanthate?
Trenbolone Enanthate is a long-acting ester of trenbolone, a synthetic anabolic-androgenic steroid (AAS) derived from nandrolone. It’s used illegally by bodybuilders and athletes to dramatically increase muscle mass, strength, and fat loss.
🔬 Key Properties
| Property | Trenbolone Enanthate |
|---|---|
| Half-life | ~7–10 days |
| Anabolic Rating | 500 (vs. testosterone at 100) |
| Androgenic Rating | 500 (high potential for side effects) |
| Detection Time | Up to 5 months |
| Administration | Intramuscular injection |
🧪 Mechanism of Action
Trenbolone binds strongly to androgen receptors, promoting:
-
Protein synthesis
-
Nitrogen retention
-
Increased red blood cell production
-
IGF-1 elevation
-
Fat burning (lipolysis)
It also does not aromatize (convert to estrogen), but can still cause progestin-related gynecomastia.
💪 Effects (Sought-After by Users)
| Positive (desired) | Negative (risky) |
|---|---|
| Rapid muscle growth | Aggression, “tren rage” |
| Increased strength | Night sweats, insomnia |
| Improved vascularity | Severe acne, oily skin |
| Hard, dry look (no water retention) | Elevated blood pressure |
| Enhanced fat burning | Gynecomastia (via progestin action) |
| No estrogenic bloat | Suppression of natural testosterone |
| Increased recovery & endurance | Kidney & liver strain |
⚠️ Side Effects & Dangers
Trenbolone Enanthate is considered one of the most toxic AAS. Risks include:
Endocrine:
-
Testosterone suppression
-
Long post-cycle recovery (PCT required)
-
Infertility
Cardiovascular:
-
Increased LDL, decreased HDL
-
Hypertension
-
Left ventricular hypertrophy
Psychological:
-
Aggression, mood swings, anxiety
-
“Tren cough” – intense coughing after injection
Liver/Kidney:
-
Potentially hepatotoxic at high doses
-
Increased creatinine and BUN (kidney stress)
🧾 Typical (Illicit) Dosage
| Use Level | Weekly Dose (Not medically recommended) |
|---|---|
| Beginner | 200–300 mg/week |
| Intermediate | 400–500 mg/week |
| Advanced | 600+ mg/week (very high risk) |
-
Injected twice per week due to enanthate ester’s long half-life
-
Often stacked with testosterone, Dianabol, or Masteron
🧠 Notable Warnings
-
Zero medical justification for human use
-
No pharmaceutical-grade Trenbolone Enanthate exists — all is underground lab product
-
Not suitable for women due to extreme androgenic activity
-
Highly suppressive, requiring robust PCT (clomid, nolvadex, hCG)
