What is 17α-Methyltestosterone?

17α-methyltestosterone (58-18-4), also called Methyltestosterone (MT or MET), is an oral anabolic steroid, which is synthesized for therapeutic purposes originally, such as low testosterone, anemia and delayed puberty in men, breast cancer treatment in women etc. As the derivative of testosterone, 17α-methyltestosterone has strong androgenic and anabolic effects and is often used in fitness and bodybuilding.

In addition, 17α-methyltestosterone is also widely used in aquaculture, especially for sex change of tilapia, improving fish production efficiency and profitability.

17α-Methyltestosterone for Medicial Use

① Testosterone replacement therapy (TRT)

As the androgen and anabolic steroid, 17α-Methyltestosterone (MT) can be used for testosterone replacement in men, especially testosterone deficiency or hypogonadism. And the typical dosage is 10 to 50 mg per day for men, which depends on testosterone deficiency and individual response. However, MT is not the first choice for TRT due to its potential hepatotoxicity and other side effects. Testosterone replacement therapy usually involves drugs such as Testosterone Enanthate or Testosterone Cypionate.

②Breast cancer treatment

In the United States, 17α-Methyltestosterone has been approved for women with advanced breast cancer who cannot undergo surgery. The common 17α-Methyltestosterone dosage is 10-20mg per day. But it can cause irreversible masculinization. With the development of medical technology, now there are newer and more targeted treatments for breast cancer. And the use of 17α-Methyltestosterone for breast cancer has become less common.

17α-Methyltestosterone for Bodybuilding

The anabolic effect of 17α-Methyltestosterone (MT) enables it to promote muscle growth and enhance performance like most steroids. And it can also enhance aggression, strength and concentration. In addition, 17α-Methyltestosterone has high oral bioavailability and is usually taken in tablets or pills. However, it is mainly metabolized by the liver, which exacerbates the side effects of liver poisoning.

17α-Methyltestosterone (MT) doesn’t have effectiveness due to the low ratio of anabolic metabolism and androgen. So bodybuilders usually stack it with other steroids such as Dianabol, Nandrolone, Trenbolone or Decanoate to enhance its effectiveness.

17α-Methyltestosterone for Sex Reversal in Fish

17α-Methyltestosterone (MET) has a methyl group attached to the 17th carbon position, which increases the oral bioavailability and stability of the steroid, making it effective in aquatic environments. Moreover, MET is a natural androgen. Therefore, it is now often used in aquaculture to promote fish growth and induce sex reversal in fish. It also has important practical significance in the production of monosexual populations of fish and improving growth rates.

17α-Methyltestosterone is often used for sex reversal in species such as tilapia and rainbow trout. In the case of tilapia, male fish grow faster and are larger than females. Therefore, in order to improve overall commercial production efficiency, 17α-Methyltestosterone will convert the sex of tilapia from genetic female to male, creating a monosexual male population. It also prevents fish from overbreeding.

In addition, 17α-Methyltestosterone is also used to promote fish growth and improve feed conversion. It can speed up the market size of fish and improve the profitability of fish farmers.

Fish farmers usually add 17α-methyltestosterone to fish feed or apply it through bath treatment so that it can be effectively absorbed. For tilapia, fish are most susceptible to the hormone at 1 to 3 weeks, ensuring effective sex reversal. And the typical 17α-methyltestosterone dosage is about 5 to 10 mg/kg feed. The 17α-methyltestosterone cycle length is usually continued for several weeks to ensure effective sex reversal.

However, this practice also has an impact on the environment. Residues of 17α-methyltestosterone may seep into natural water systems, affecting local aquatic ecosystems and wildlife. And people may also be concerned about the presence of hormone residues in the fish they eat, which may cause health hazards.

How does 17α-Methyltestosterone Work?

The mechanism action of 17α-Methyltestosterone (MT) likes most anabolic steroids, which  mimicks the natural hormone testosterone. It binds to androgen receptors to promote protein synthesis, muscle growth, and various secondary male characteristics.

17α-Methyltestosterone Side Effects

Potential side effects are inevitable when 17α-methyltestosterone is used improperly or for a long time:

Common side effects of 17α-methyltestosterone include:

①Androgenic effects:

• Increased body hair
• Acne
• Oily skin
• Baldness
• Deepening of voice
• Increased aggression
• Seborrheic dermatitis
• Scalp hair loss
• Increased libido

②Estrogenic effects:

• Male breast development (male breast development)
• Water retention

③Hepatotoxicity

④Cardiovascular effects:

• Increased risk of heart disease
• Stroke
• Hypertension

⑤Other potential side effects may include:

• Headache
• Nausea
• Vomiting
• Insomnia
• Mood swings

It should be noted that these side effects may vary depending on personal factors, 17α-Methyltestosterone dosage, and duration of use. If you are considering using 17α-methyltestosterone, be sure to consult a healthcare professional in advance.

What are Differences between Testosterone and 17α-Methyltestosterone?

Testosterone is a natural hormone with a wide range of medical uses, essential for maintaining normal male sexual development and function. It is usually administered by injection. 17α-methyltestosterone is a synthetic variant for oral administration, modified to affect its metabolism but also increase the risk of side effects. Although they are used to control testosterone levels, testosterone is more popular among bodybuilders and 17α-methyltestosterone is more commonly used in aquaculture to help fish change sex.

17 alpha Methyltestosterone Powder Testing Report-HNMR

What is HNMR and What does HNMR spectrum tell you? 
H Nuclear Magnetic Resonance (INMR)spectroscopy is an analytical chemistry technique used in quality control
and research for determining the content and purity of a sample as well as its molecular structure. For 
example, NMR can quantitatively analyze mixtures containing known compounds. For unknown compounds, NMR 
can(either be used to match against spectral libraries or to infer the basic structure directly. Once the
basic structure is known, NMR can be used to determine molecular conformation in solution as well as 
studying physical properties at the molecular level such as conformational exchange, phase changes,
solubility, and diffusion.
