Fluoxymesterone (commonly known as Halotestin) has been a favorite in the arsenal of strength athletes and bodybuilders for decades. It is a Testosterone derivative and offers unique properties:

• Extremely High Androgenicity: Explained by its conversion via the 5-alpha reductase enzyme.
• No Aromatization: The 11-beta hydroxyl group prevents conversion into estrogen, which excludes typical estrogenic side effects (e.g., water/fat retention, gynecomastia).

The combination of extremely high androgenicity and the inability to convert to estrogen makes Fluoxymesterone an optimal compound for **cutting and strength phases**.

Key Benefits:

• Definition and Hardness: When used at low body fat levels (below 8%), it gives the musculature a harder, more defined, and **"stage-ready" appearance**.
• Strength Increase: Significant strength gains are highly valued by weightlifters, powerlifters, and Strongmen.
• Training Aggression: The substance causes extreme aggression, which is advantageous for intense training while strictly limiting calories.

Due to its weak anabolic action, Halotestin makes **little sense during the bulking phase**.

Specialized Use (Pre-Workout Boost):

Fluoxymesterone is often used as a "boost" directly before difficult training sessions. A dose of 20–30 mg is taken **sublingually** 30–45 minutes before the workout. This method directly stimulates androgen receptors in the central nervous system, significantly boosting readiness for training in a short time. It is ideal for athletes in weight classes (boxers, wrestlers) who require strength without mass gain.

Halotestin is 17-alpha alkylated and is considered one of the most toxic AAS on the market. Its short-term use is mandatory due to the high stress on organs.

Major Side Effects:

• Liver and Digestive System: Clearly elevated stress on the liver, stomach, and intestines due to 17-alpha alkylation. Long-term use is strictly prohibited.
• Androgenic Effects: Hair loss, acne, oily skin, and prostate enlargement—direct results of potent conversion to DHT.
• Cardiovascular System: Stress on the heart and circulatory system, and deterioration of blood lipid values.
• Psychological: Mood changes, increased aggression, headaches, and nosebleeds.

Testosterone Suppression: Despite the lack of estrogen conversion, this substance quickly and significantly **blocks the body's own testosterone production**. An intensive Post Cycle Therapy (PCT) is necessary after use.

Halotestin is not suitable for **beginners or women**, as it is too androgenic, weakly anabolic, and has too many side effects. Women should particularly fear the extreme androgenicity and the associated signs of masculinization.

• **Potential Users:** Only advanced powerlifters and bodybuilders.
• **Daily Dose:** 30–60 mg, divided into three equal doses (e.g., 3x10 mg or 3x20 mg) for better stomach tolerance.
• **Cycle Duration:** Usually the **final 4–6 weeks** before a competition.

Popular Stacks: Halotestin is combined with steroids such as **Trenbolone, Stanozolol, and Testosterone Propionate**, which together guarantee maximum strength and a stage-ready appearance.
