🧪 Product Overview

Halotestin 5 mg provides fluoxymesterone, a potent 17-α-alkylated, 9-fluoro androgenic steroid with roughly 5× the androgen-receptor (AR) affinity of testosterone. It’s a gold standard in strength-focused AAS research, particularly for muscle-performance modeling, neural drive stimulation, and non-estrogenic lean-mass retention.

Its small 5 mg dosing allows precision micro-administration in both low- and high-resolution sampling models. With ~100% oral bioavailability and a mean half-life of 9 hours, Halotestin is ideal for acute PK/PD trials involving strength output, aggression, and hormonal modulation—without estrogen conversion.

✅ Key Research Highlights

Explosive strength modeling: ~5× AR binding vs. testosterone supports peak-force output studies
Zero aromatisation: No estrogenic conversion — ideal for lean-gain without gynecomastia risks
Neural & aggression activation: Reported increases in CNS stimulation and workout aggression
Hepatic monitoring required: High risk of cholestatic jaundice and liver stress beyond 20 mg/day
WADA S1 banned: Any exposure yields a positive anti-doping result

🔬 Suggested Laboratory Applications

Androgen-receptor pathway modeling
Non-estrogenic strength gain simulations
Lean muscle maintenance in caloric-restriction studies
CNS aggression and neural drive research
Hepatotoxicity and cholestasis mechanism analysis
