Trenbolone Acetate
Powerful 19-nor compound. Highly androgenic and anabolic. Short ester.
Overview
Powerful 19-nor compound. Highly androgenic and anabolic. Short ester.
Severely worsens lipids (especially HDL), can elevate prolactin, may affect thyroid function, increases haematocrit, can elevate liver enzymes, does not aromatize but has progestogenic activity
Compound Guide
Ester: Acetate -- 2-carbon chain ester. Very short half-life requiring daily or EOD injection. Peak levels within hours, allowing rapid dose titration.
Dosage:
- Low dose (recomp): 150-250 mg/week
- Enhancement: 300-400 mg/week for 6-8 weeks (experienced users)
- No TRT/cruise application -- Tren is not a base compound
Injection Protocol:
- Inject daily or EOD for stable levels
- 27-29g needle, 0.5-1 inch, delts/VG/quads
Key Notes:
- One of the most powerful AAS -- 5x the anabolic and androgenic rating of testosterone
- Does NOT aromatise but has strong progestogenic activity (can still cause gyno via prolactin)
- Monitor prolactin closely -- have Cabergoline on hand
- Known side effects: night sweats, insomnia, increased aggression, cardiovascular strain, "tren cough"
- Severely impacts lipids -- HDL often crashes to near-zero; limit cycle length
- Acetate ester preferred over Enanthate because sides clear faster if dropped
- Not recommended for first-time users or those prioritising health
