Product Introduction

A synthetic anabolic–androgenic steroid; the equine linear ester counterpart of Equipose activity. No verified independent Chinese label information beyond the source file.

Therapeutic Use

Veterinary use for weight gain and mane quality in horses; not approved for human medical use; research compound only

Mode of Action

Ester prodrug requiring esterase hydrolysis to boldenone; androgenic plus anabolic activity; retains some aromatisation (unlike trenbolone)

Administration & Monitoring

Veterinary or research use only; in animals monitor weight, mane, behaviour and reproductive status

Important Safety Information

Controlled / research anabolic steroid — purchase, storage and transport must comply with local regulations; non-clinical use is unlawful and hazardous

Adverse Reactions

Androgenic effects: acne, hirsutism, aggression/territorial behaviour, elevated liver enzymes, prostatic hyperplasia; comparatively higher hepatorenal toxicity; reproductive disturbance in animals

Important Risks

High abuse potential; cardiovascular (polycythaemia, dyslipidaemia), hepatotoxicity, reproductive suppression; adulteration risk

Contraindications

Contraindicated in pregnancy and lactation; known or suspected prostate or breast cancer; severe hepatic or renal impairment

Special Populations

Paediatric/adolescent use contraindicated (open epiphyses); older males require prostate and cardiovascular assessment; breeding females must not be treated

Usage Limitations

Not for human bodybuilding or performance enhancement; restricted to licensed veterinary and compliant research use; subject to Schedule III/IV-type controls

Anti-Doping Testing

WADA Prohibited List S1.1 (anabolic steroids); targets boldenone and its major metabolites, detectable by GC-MS/MS and LC-MS/MS

Product Quality Testing

Identification (HPLC retention + MS or FTIR), assay/content uniformity, related substances, clarity and particulate matter, fill volume, sterility and endotoxin for injectables, stability and residual solvents; COA recommended
