History of Methyltrienolone

Methyltrienolone was briefly investigated as a possible treatment for advanced breast cancer in women in the 1960s and 1970s. However, such use was short-lived, since more realistic assessments of the drug’s toxicity quickly led to its withdrawal from human medicine. Even at low doses, methyltrienolone powder is highly hepatotoxic. Methyltrienolone Powder has never been approved for use in medicine.

By the mid-1970’s, methyltrienolone was becoming an accepted standard in non-human research studies, particularly those pertaining to the study of the androgen receptor activity. The reason being is that the steroid is so resistant to the bodies metabolism it doesn’t interfere with the results of most experiments.

Body tissue can quickly metabolize with most steroids, this can complicate studies when trying to understand what is causing a particular effect, using Methyltrienolone Powder reduces many of the variables making it the primary steroid for research purposes.

Despite its toxicity, the steroid was used by 11 members of the Greek weight lifting team and 4 Greek track and field competitors who all tested positive for Methyltrienolone (Metribolone) during the 2008 Beijing Olympics.

What is Methyltrienolone Powder

Methyltrienolone Powder, also know as metribolone, oral tren and Mtren. It is one of the strongest oral anabolic steroids ever produced. This drug is a trenbolone derivative that has been c-17 alpha alkylated to allow for oral administration.This modification has resulted in a steroid that is substantially more potent than its non-methylated version. Its efficacy has been measured to be 120-300 times that of methyltestosterone, with greater separation of anabolic and androgenic effects. Methyltrienolone Powder is a more active steroid milligram for milligram than any other steroid on the market, requiring doses as little as 0.5-1 mg per day to produce a strong anabolic effect. However, except being extremely powerful in terms of anabolic effects – it is also extremely powerful in term of toxicity, which has limited its modern use to that of laboratory research only.

How does Metribolone Powder work?

Metribolone Powder works by binding to the androgen receptor. Methyltrienolone Powder binds strongly with androgen receptors causing a significant increase in androgen production. Androgens are essentially male sex hormones that are responsible for anabolic effects in humans. It should be noted that androgen receptors are the primary mechanism by which these hormones have anabolic effects. They activate several genes, resulting in an increase in muscle mass and strength over time.

One of numerous androgens, testosterone is the major hormone responsible for tissue development and repair. Androgen receptors are in charge of ensuring that the body successfully responds to the hormone that has been released. This connection transports testosterone to skeletal muscle cells, where it exerts its function.

In simple terms the stronger the bond of androgen receptors is the easier it isto burn fat and gain muscle.

Methyltrienolone (Metribolone) Powder benefits in bodybuilding

Although its use is restricted to laboratory settings due to its severe toxicity, it has found widespread use in bodybuilding among individuals who are knowledgeable enough to do so. Methyltrienolone Powder has the ability to strongly bond to androgen receptors. This is the most advantageous benefit of the medicine for bodybuilders because these androgen receptors may be found in muscle and fat cells, implying that cell development is promoted. Because how strongly a chemical attaches to the receptor influences how effective fat burning is, Methyltrienolone Powder has a significant influence in body fat reduction and muscle mass increase.

Methyltrienolone (oral tren) Powder side effects


Even though Methyltrienolone Powder is an anabolic steroid, it may cause androgenic side effects. Facial hair, male pattern baldness, greasy skin, and acne are examples of this. Women should avoid this steroid at all costs because of its potentially significant virilizing effects, which could result in clitoral enlargement, facial hair, and voice deepening.


Metribolone Powder has no estrogenic action and does not aromatize. It can, however, connect to the progesterone receptor; progesterone adverse effects are similar to those generated by estrogen; they can block testosterone production and accelerate fat gain. It can also induce fat growth in the breast tissues (gynecomastia), which can be prevented by taking an anti-estrogen.


Because Methyltrienolone Powder is a c17-alpha alkylated molecule, the modification protects the drug from deactivation by the liver, allowing a large amount of the drug to enter the bloodstream and negatively impact the liver.

Long-term use may cause life-threatening liver damage in rare situations.

Even in little amounts. If you decide to use this oral steroid, your liver enzymes should be constantly checked.

It is also recommended to use supplements to avoid damage; some people may consider taking milk thistle, which may help prevent liver damage.


Methyltrienolone Powder will likely mess with your cholesterol levels, as is typical of anabolic steroids. It has a propensity to lower HDL (good) cholesterol levels and raise LDL (bad) cholesterol, which over time can result in arteriosclerosis. However, because it is an oral steroid, its propensity to change lipid values is much higher.

Testosterone suppression

Anabolic steroids that are used to increase muscle all have one thing in common and that is that they suppress your own bodies natural endogenous testosterone production.

How to use Methyltrienolone (oral tren) Powder, cycle and dosage?

Oral androgenic steroids may be less bioavailable when taken Methyltrienolone (Oral tren) Powder with food, according to studies. Some androgenic steroids may dissolve in fat because they are fat-soluble. This may result in less absorption in the digestive system. For best results, take Methyltrienolone (Oral tren) Powder on an empty stomach. And first of all, you should buy Methyltrienolone Powder with original manfaucturer, and wholesale buy Methyltrienolone Powder will get good price.

Because of its significant hepatotoxicity, methyltrienolone is not suggested for usage in boosting physique or performance. Those considering using Methyltrienolone Powder should be aware that the possibility of liver injury from this steroid exists. At the very least, routine blood tests should be conducted to ensure the agent is not imparting damage. And it is also very important to buy high quality Methyltrienolone Powder from reliable supplier.

Those who persist on utilizing this steroid should keep their cycles to no more than four weeks; in this situation, less is more. The relative potency of Methyltrienolone Powder (Oral tren) is extremely high, requiring doses as little as 500 mcgs per day. Its effective and tolerable range is usually considered to be 500-700mcgs per day.

The half-life of Methyltrienolone Powder is 4-6 hours. Since the steroid has never been fully tested in humans the detection time is unknown.

Methyltrienolone Powder is no longer used in clinical medicine due to an unacceptable level of hepatotoxicity.This agent is not recommended for women for physique-or performance-enhancing purposes due to its extremely strong toxicity and tendency to produce virilizing side effects.

Even there are many Methyltrienolone Powder for sale online, this is an extremely toxic steroid powder, and all good advice would say to avoid it. Any of the several commercially available steroids would be far safer options. If you look for steroid powder, AASRAW will be the one suppllier you don’t want to miss.

Methyltrienolone(Mtren) Powder – ls it safe?

Methyltrienolone (Mtren) Powder is a strong and toxic anabolic steroid that does not aromatize. Due to its hepatotoxic nature, it is rarely talked about, however,there have been some who have taken the risk and used this anabolic steroid.With so many milder steroids available this is one that should be avoided.

Methyltrienolone (Metribolone) Powder Testing Report-HNMR

Methyltrienolone powder HNMR

What is HNMR and What does HNMR spectrum tell you?H Nuclear Magnetic Resonance (NMR) 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.
