Halotestin (Fluoxymesterone )

Description

Halotestin is the trade name for fluoxymesterone, a synthetic oral anabolic-androgenic steroid (AAS).

Key characteristics:

• Extremely androgenic
• Relatively low anabolic mass-building effect
• 17-alpha-alkylated → very harsh on the liver
• No estrogen conversion (no aromatization)

Originally, it was prescribed for:

• Delayed puberty (historically)
• Certain breast cancers
• Severe testosterone deficiency (rare today)

Halotestin  used by athletes because it can:

• Increase neural drive and aggression
• Increase strength output without weight gain
• Improve competitiveness and confidence

This made it attractive in:

• Powerlifting
• Olympic weightlifting
• Combat sports
• Strength sports with weight classes

It was typically associated with short-term performance peaks, not long training phases.

Important reality check

Despite its reputation:

• It does not build large muscle mass
• Gains are often neurological, not structural
• Performance effects disappear quickly after discontinuation
• Side effects can outweigh benefits for most people

Side effects

Halotestin is considered one of the harshest oral steroids.

Liver toxicity

• Strongly hepatotoxic
• Elevates liver enzymes significantly
• Long-term use can cause cholestasis, hepatitis, liver damage

Cardiovascular risks

• Severely worsens cholesterol (↓ HDL, ↑ LDL)
• Increases blood pressure
• Raises risk of heart attack and stroke

Hormonal suppression

• Strong suppression of natural testosterone
• Can cause testicular atrophy
• Libido crashes after discontinuation

Psychological effects

• Aggression
• Irritability
• Anxiety
• Mood instability
• In some cases: paranoia or impulsive behavior

Androgenic effects

• Hair loss (especially if genetically prone)
• Acne
• Oily skin
• Prostate stress

Notably:
Because it is very androgenic, side effects can appear quickly, even at low exposure.

Medical dosages

These are clinical, not athletic:

• Fluoxymesterone (Halotestin) tablets are typically 2 mg, 5 mg, or 10 mg. com
• In medical practice, doctors sometimes use about 5–20 mg per day for conditions like hypogonadism. com
• In cancer treatment, doctors sometimes prescribe 10–40 mg per day in divided doses. org

These doses are for treating disease, not performance enhancement.

⚠️ What to keep in mind

If someone searches online for “Halotestin doses,” they’ll likely find ranges and cycle lengths discussed in fitness communities, but:

• Fluoxymesterone is a controlled substance with medical dosing tailored to specific diseases. com
• Misuse for performance can lead to serious health problems including liver damage, cardiovascular harm, hormone disruption, mood effects, and more. Cleveland Clinic
• Best practice — if someone is concerned about hormones, strength, or performance — is to consult a licensed healthcare provider.
