What is 17-alpha-Methyltestosterone Powder?

17a-Methyltestosterone(MT), a synthetic derivative of testosterone, is an androgenic preparation given by the oral route in a capsule form.

Methyltestosterone also known as 17-alpha-Methyltestosterone, 17a-MT, methyltest, or 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, 17-Methyltestosterone Powder has relatively high estrogenicity and hence potential side effects such as gynecomastia.

How does 17-Methyltestosterone powder work?

17-alpha 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.

17 alpha Methyltestosterone Powder uses – What is methyltestosterone (MT) powder used for?

Medical use

17 alpha 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.

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.

17 alpha Methyltestosterone Powder (MT) use in the Tilapia sex reversal

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

Benefits of 17-Methyltestosterone Powder in Aquaculture and Bodybuilding

In aquaculture

Tilapias are a widely farmed fish species that dominate the global aquaculture business, with only carps and salmon coming close.

If you own a fish farm, early maturation and frequent spawning are management challenges when working with tilapia. The precocious breeding of tilapia, especially in ponds, with fish maturing as small as 8cm in length, bedevilled their culture for many years. Male fish grew substantially quicker than females, who spent the majority of their energy producing eggs and fry. As a result, the production of all-male fish became critical.

One of the most commom methods for commercial production of all make tilapia populations is to use 17 alpha Methyltestosterone Powder (MT). If you want to buy 17a-Methyltestosterone (MT) Powder, AASRAW is one of the supplier you don’t want to miss.

Production of male tilapia through the use of androgens is very effective. It does not require that a portion of the production be discarded as in manual selection, or that 2 separate stocks of fish be maintained as in hybridization. There are several seed production techniques adaptable to most scales of production. The relative ease and predictability of tilapia sex reversal has been a major factor in the rapid growth of the industry. Although a variety of hormones have been used for tilapia sex reversal, 17a-Methyltestosterone Powder is the most commonly used one. In order to reduce the cost of farming, it will be a good idea to buy 17-Methyltestosterone Powder wholesale. There are many 17-Methyltestosterone Powder for sale online. However, buy it from a reliable supplier is the most important. The Reliable supplier will guarantee you high quality and real products. Purchase 17a-Methyltestosterone Powder wholesale from AASRAW manufacturer will get a good price.

For example, 17 alpha-Methyltestosterone (MT) Powder incorporated into the feed at precise levels produced about 99,8% males. This is now the established method for producing quality tilapia fingerlings – but does the use of a hormone mean the fish are safe to eat?

It has been demonstrated that the hormone does not have any adverse effect on fish flesh after cessation of treatment of tilapia fry. Ingestion of fish produced by sex reversal does not equally harm man. However, one is not too sure of the effect of the hormone or its bye products on vital organs (liver, kidney, pancreas and gills) metabolic profile and nucleic acids. On the environment, the steroid is either biodegraded or mineralized. It must be stated that escapee from tilapia hatchery into the natural water may alter the dynamics of the environment due to unforeseen consequences.

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.

Where to buy 17-Methyltestosterone Powder wholesale?

17 alpha Methyltestosterone Powder Testing Report-HNMR

17-Methyltestosterone powder 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.
