• 11β-hydroxysteroid dehydrogenase 2 inhibition 

• Anabolic and androgenic response characterization

• Pharmacokinetic and metabolic profiling

Frequently Asked Questions

1. What is fluoxymesterone (Halotestin)?
Fluoxymesterone is a synthetic androgenic steroid and a 17α-alkylated derivative of testosterone, developed for its potent androgenic properties . It is distinguished by a high androgenic-to-anabolic activity ratio compared to other AAS compounds.

2. What is the half-life of fluoxymesterone?
The half-life of fluoxymesterone after oral administration is approximately 9.2 hours . The compound is metabolized primarily in the liver and excreted through urine .

3. What is the mechanism of action?
Fluoxymesterone mediates its effects through the androgen receptor (AR), despite having relatively low affinity for the receptor . During exogenous administration, endogenous testosterone release is inhibited through feedback inhibition of pituitary luteinizing hormone (LH) .

4. What is the recommended research dosage range?
Research protocols typically utilize dosages between 10-40mg daily depending on specific study parameters . The 5mg tablet format allows for precise dose adjustment to meet research requirements.

5. Is fluoxymesterone estrogenic?
Fluoxymesterone exhibits minimal estrogenic activity, making it suitable for research protocols where water retention interference is a concern . This characteristic is relevant for body composition and performance studies.

6. What are the documented clinical applications?
Clinically, fluoxymesterone is indicated for replacement therapy in male hypogonadism, delayed puberty, and for palliation of androgen-responsive recurrent breast cancer in postmenopausal women .

7. What are the known side effects in clinical use?
Side effects may include liver function changes, cardiovascular effects including cholesterol profile alterations, virilization in females, acne, mood changes, and electrolyte imbalances . Regular monitoring of liver function is recommended during prolonged administration .

8. What is the purity specification for this product?
This product is manufactured to ≥99% purity as verified by HPLC analysis, meeting CRM-grade quality standards for research applications.

9. What is the significance of the 17α-alkylation?
The 17α-alkylation modification allows for oral administration by protecting the compound from first-pass hepatic metabolism, ensuring complete oral bioavailability .

10. How should this product be stored?
Store in a cool, dry environment at controlled room temperature, protected from light and moisture. The sealed blister packaging preserves product integrity and stability.
