Description
Overview
Highly potent androgen-receptor agonist; non-aromatizing but progestogenic; strong nutrient partitioning.

Format
- Oil-based (or aqueous, where noted) solution for intramuscular injection

Dosage & Usage Patterns
- Bodybuilding (commonly cited): Commonly cited: acetate ~200–400 mg/week (EOD/E3D); enanthate/hexa ~200–400 mg/week (2× weekly). Among the most potent compounds per milligram.
- Clinical / general reference: Individual and a matter for a clinician; trenbolone is among the most potent compounds and side-effect-heavy.
- Half-life: Acetate ~1 day; enanthate ~4-5 days; hexahydrobenzylcarbonate (Parabolan) ~5-7 days.
- Protocols vary by individual, compound stack, and bloodwork — figures above reflect community-reported patterns, not medical recommendations.
Effects
Reported benefits (commonly cited)
- Extreme nutrient partitioning.
- Fat loss while retaining muscle.
- Dramatic strength and hardness.
- Non-aromatizing but highly androgenic and progestogenic.
Reported side effects
- Night sweats, insomnia, aggression/mood changes, cardiovascular strain, ‘tren cough,’ prolactin/progestogenic effects, marked libido and mental-health effects.
Key Interactions
- Progestogenic (prolactin relevant).
- Does not aromatize so AIs don’t address its estrogen-independent sides.
Post-Cycle Considerations
- Strong, prolonged HPTA suppression.
Precautions
- One of the most side-effect-intensive AAS, including cardiovascular and neuropsychiatric effects.
- No human therapeutic use.
Common Misconception
Myth: ‘no aromatization means no gyno.’
Evidence: trenbolone can still cause gyno via progestogenic/prolactin pathways.
