1. What is 17-alpha-methyltestosterone powder?

Methyltestosterone, a synthetic derivative of testosterone, is an androgenic preparation given by the oral route in a capsule form. Methyltestosterone occurs as white or creamy white crystals or powder, which is soluble in various organic solvents but is practically insoluble in water.

Methyltestosterone also known as 17-alpha-methyltestosterone, 17a-MT,  methyltest or as 17α-methylandrost-4-en-17β-ol-3-one, is a synthetic, orally active androgenic-anabolic steroid (AAS) and 17α-methylated derivative of testosterone that is used to treat males with androgen deficiency. It bears close structural similarity to testosterone, but has a methyl group at the C17α position in order to increase oral bioavailability. Due to efficient aromatization into the potent estrogen methylestradiol, methyltestosterone powder has relatively high estrogenicity and hence potential side effects such as gynecomastia.


2. How does methyltestosterone powder work?

Methyltestosterone powder is a testosterone replacement that acts like the natural sex hormone. Testosterone is responsible for the development and maintenance of many male features during and after puberty. Since methyltestosterone powder is a form of testosterone, it works by adding or replacing testosterone in the body to normal and healthy levels.

It’s unclear how methyltestosterone powder works to treat breast cancer, but it’s thought to slow the spread of the cancer in females by stopping tumor growth.


3. 17 alpha methyltestosterone powder uses – What is methyltestosterone powder used for?

(1) Medical use

Methyltestosterone powder is or has been used in the treatment of delayed puberty, hypogonadism, cryptorchidism, and erectile dysfunction in males, and in low doses to treat menopausal symptoms (specifically for osteoporosis, hot flashes, and to increase libido and energy), postpartum breast pain and engorgement, and breast cancer in women. It is specifically approved in the United States for the treatment of hypogonadism and delayed puberty in males and the treatment of advanced inoperable breast cancer in females. It was also approved in low doses in combination with esterified estrogens for the treatment of moderate to severe vasomotor symptoms associated with menopause in women in the United States, but this formulation was discontinued and hence is no longer used.

17a-Methyltestosterone powder is less effective in inducing masculinization than testosterone, but is useful for maintaining established masculinization in adults.

The dosages of methyltestosterone powder used are 10 to 50 mg/day in men for common medical uses like hypogonadism and delayed puberty as well as physique- and performance-enhancing purposes and 2.5 mg/day in women for menopausal symptoms. Higher methyltestosterone powder dosages of 50 to 200 mg/day have been used to treat women with inoperable breast cancer that has failed to respond to other therapies, although such dosages are associated with severe irreversible virilization.


(2) Non-medical use

Methyltestosterone powder is used for physique and performance-enhancing purposes by competitive athletes, bodybuilders, and powerlifters, although it is not commonly used relative to other AAS for such purposes.


(3) Other uses

The 17 alpha methyltestosterone (MT) powder is fed to Tilapia (Oreochromis niloticus) larvae in fish farms with the purpose of inducing sex reversal.


4. 17 alpha methyltestosterone powder benefits in the bodybuildings

1)Methyltestosterone powder benefits to increase in Performance

Methyltestosterone powder acts by inhibiting the catabolic activity and promoting anabolism. This action, in turn, increases the performance, improves the overall strength, and boosts the psyche. For bodybuilders, powerlifters, and active sportspersons, these methyltestosterone benefits are a plus. The user gets to do intense training with a lot of energy and maximum stamina without tiring out.


2) Methyltestosterone powder benefits to increases Aggressiveness

Do you want to be the tough guy in the neighborhood? Well, methyltestosterone powder will do. Any participant of the combat sports will want to spice up their aggression, strength, and focus during the match.


3) Methyltestosterone powder benefits to increases Muscle Mass

Although you may not gain substantial bodyweight, you can still bank on the drug to kick start your methyltestosterone bulking cycle. You should note that an increase in body size is always due to water weight as the hormone aromatizes.


4) Fast-Acting Steroid

With methyltestosterone powder, you will feel the impact of the drug, not more than an hour after taking it. The changes are noticeable in the nick of time for one reason. The steroid has a short half-life. Hence, it will reach its peak at the count of three.


5. What are the side effects of methyltestosterone powder?

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if you have:

▪ changes in skin color;

▪ increased or ongoing erection of the penis;

▪ shortness of breath (even with mild exertion);

▪ swelling, rapid weight gain; or

▪ liver problems–nausea, upper stomach pain, itching, tired feeling, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes).


Women using methyltestosterone powder may develop male characteristics, which could be irreversible if treatment is continued. Stop using this methyltest and call your doctor at once if you notice any of these signs of excess testosterone:

▪ acne;

▪ changes in menstrual periods;

▪ male-pattern hair growth (such as on the chin or chest);

▪ hoarse or deepened voice; or

▪ enlarged clitoris.


Common side effects (in men or women) may include:

▪ breast swelling;

▪ headache, anxiety, depressed mood;

▪ numbness or tingly feeling; or

▪ increased or decreased interest in sex.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects.

(5) What is the half life of methyltestosterone powder ?

17α-Methyltestosterone powder is rapidly absorbed, with maximal testosterone levels achieved 90–120 min after ingestion; plasma half-life is 150 min.


(6) What is the difference between testosterone and methyltestosterone powder?

Testosterone is a natural sex hormone your body makes. Testosterone is involved in the development and maintenance of male features, including the development of the penis and scrotum, deepening of the voice, hair growth on the face and body, and bigger muscles. As a medication, if natural testosterone is taken by mouth, very little is absorbed in the body. On the other hand, methyltestosterone powder is a man-made form of testosterone that acts like the natural sex hormone, but more is absorbed into the body and stays in the body for a longer period of time.


(7) Does methyltestosterone powder cause liver damage?

Methyltestosterone powder can cause serious liver damage. This is more likely to happen if you use the medication for a long period of time and at high doses. Symptoms include stomach pain, nausea, vomiting, yellowing of the skin and whites of the eyes, light-colored stools, and dark urine. Let your provider know if you experience any of these symptoms. You might need occasional blood tests so your provider can check that your liver is healthy.


(8) Is methelytestosterone powder a steroid?

Methyltestosterone powder is an anabolic steroid hormone used to treat men with a testosterone deficiency. It is also used in women to treat breast cancer, breast pain, swelling due to pregnancy, and with the addition of estrogen it can treat symptoms of menopause.
