Methylstenbolone

Methylstenbolone is a synthetic, orally active anabolic-androgenic steroid (AAS) that was never approved for medical use. It is a derivative of dihydrotestosterone (DHT). It's most commonly known by its nicknames M-Sten, Methyl-Sten, and Ultradrol.

Side Effects and Benefits

Methylstenbolone's primary "benefit" for bodybuilders is its potent anabolic effect, which leads to rapid increases in muscle mass and strength. However, this comes with a high risk of significant side effects, including:

• Liver Toxicity: As a 17α-alkylated compound, it is highly hepatotoxic and can cause severe liver damage, including cholestatic jaundice.

• Androgenic Side Effects: Due to its androgenic nature, it can cause hair loss, acne, and an enlarged prostate (BPH) in men. In women, it can lead to virilization symptoms like a deepened voice, clitoral enlargement, and body hair growth.

• Cardiovascular Strain: It can negatively impact cholesterol levels, significantly lowering HDL ("good") cholesterol and increasing LDL ("bad") cholesterol, which increases the risk of cardiovascular disease.

• Hormonal Suppression: It causes severe suppression of natural testosterone production, which can lead to post-cycle erectile dysfunction, loss of libido, and depression.

• Other Side Effects: Users may also experience lethargy, joint pain, and an increase in aggression or mood swings.

Pros and Cons

The main pro of Methylstenbolone is its high potency for muscle and strength gains. However, this is heavily outweighed by the significant and potentially life-threatening cons, which include:

• Cons:

  • Extreme liver toxicity.

  • Severe suppression of natural hormone production.

  • High risk of androgenic and cardiovascular side effects.

  • Illegal to sell for human consumption in many countries.

  • No therapeutic use or safety data.

Due to the severe side effects and lack of medical benefits, the cons of using Methylstenbolone far outweigh any potential pros.

Dosage, Frequency, Half-Life, and Detection

There is no standard medical dosage for Methylstenbolone as it was never intended for therapeutic use. Information on "dosage" comes from anecdotal reports and bodybuilding forums, which are unreliable and not recommended.

• Dosage & Frequency:

  • Typical user-reported dosages range from 10-20 mg per day.

  • Because of its short half-life, users often split the daily dose into two, taking it in the morning and evening to maintain stable blood levels.

• Half-Life:

  • The half-life of Methylstenbolone is not officially documented. However, because it's an orally active steroid, its half-life is believed to be short, likely just a few hours. This is why it requires frequent dosing.

• Detection Time:

  • Detection times for steroids can vary widely based on individual metabolism, dosage, and testing methods (urine, blood, hair). While the half-life is short, its metabolites can remain in the body for much longer. Its detection time is not well-documented, but a reasonable estimate for similar oral steroids would be several weeks to a few months.

Sterogenic, Progestogenic, and Prolactin Effects

• Progestogenic Effects: Methylstenbolone is a derivative of DHT, which is not progestogenic. It does not directly interact with progesterone receptors. Therefore, it does not typically cause progestogenic side effects like gyno (breast tissue development) on its own.

• Prolactin Effects: Like other anabolic steroids, Methylstenbolone's use can indirectly cause an increase in prolactin levels due to the suppression of natural testosterone and the body's attempt to regulate hormones. However, it is not considered a primary "prolactin-inducing" steroid in the way that 19-nor compounds like Trenbolone or Deca-Durabolin are.

• Anabolic-Androgenic Ratio: The anabolic-androgenic ratio is a way to measure a steroid's relative anabolic (muscle-building) and androgenic (masculinizing) effects. Testosterone's ratio is considered 100:100.

  • Methylstenbolone is reported to have a very favorable ratio, with its anabolic score being much higher than its androgenic score.

  • While specific, verified numbers are unavailable from official studies, anecdotal reports from the bodybuilding community often cite a ratio in the range of 100:20-60. This suggests it is a very potent muscle builder with lower, but still significant, androgenic side effects.
