Hormone, anabolic & androgen-receptor research compounds
Trenbolone
Also known as 17β-trenbolone · trenbolone acetate · trenbolone enanthate · tren
A potent 19-nor anabolic steroid approved only as a veterinary growth promoter for cattle — never as a human medicine.
In 60 seconds
Veterinary use only (beef-cattle implants); not approved for humans anywhere. Studies in people who use anabolic steroids associate trenbolone specifically with psychological distress and aggression; animal and environmental studies report neurobehavioural effects.
- Reviews trenbolone’s tissue selectivity and its reduced androgenic/oestrogenic activity in animal studies.
- Reviews organ-level effects of trenbolone, which is used illegally by athletes and amateurs.
- Among men using anabolic steroids, trenbolone use was examined for association with distress and aggression.
Mechanism
Trenbolone binds the androgen receptor with high affinity and resists aromatisation; it is studied for strong anabolic effects with reduced androgenic and oestrogenic activity in animals.
Research status
Veterinary use only (beef-cattle implants); not approved for humans anywhere. Also an environmental endocrine disruptor in research.
