Metribolone (Methyltrienolone, 7α-methyl-19-nortestosterone) is a very potent, reasonably toxic, non-aromatizable androgen which also has pronounced androgenic properties. It is 17-alpha alkylated, and this alteration protects it from deactivation by the liver. The drug has an active life of approximately 2 days, and available data seems to suggest that there may be significant accumulation in the body with prolonged use. While metribolone itself can be detected in the urine for only 3 days after administration, its metabolites can be detected for up to 6 weeks. It has a reputation for being a very harsh compound that can cause many side effects.
Methyltrienolone is an orally active androgen, although its bioavailability is low (~10%). It has an active life of 48 – 72 hours. In contrast with most other 17-alpha alkylated steroids, Methyltrienolone is not known to have progestational activity, which may give it some advantage over other AAS as far as muscle mass promotion goes.
In addition to promoting muscle tissue growth, 7α-methyl-19 Nor also greatly increases erythrocytes and hemoglobin within the blood which enhances endurance. This particular property is one of the reasons why athletes often take this compound before going for a game or a match. These athletes refer to this practice as ‘blood-loading’.
Who uses metribolone steroids?
Metribolone is largely used by powerlifters and weight lifters, as well as athletes that engage in sports that require bursts of strength or energy. 7α-methyl-19 Nor does not aromatize into estrogenic metabolites, so the loss of muscle mass often experienced during post-cycle therapy is circumvented. This makes it a popular choice for professional bodybuilders who are about to start a contest preparation stack.
Methyltrienolone is considered one of the most powerful AAS available; its only legitimate medical use in the treatment of advanced breast cancer in women (in conjunction with other drugs). The dosage used for this purpose typically ranges between 0.5 – 1 mg per day orally (taken with food).
Is it safe for women?
Methyltrienolone is not recommended for women due to its extremely strong virilization effects. Its use by healthy men is also discouraged, but in light of the low availability of this compound, many users take the risk. Methyltrienolone can cause huge increases in aggression and rage with possible psychotic manifestations.
What are metribolone steroid side effects?
Side effects of metribolone include: nausea, appetite loss, insomnia, headaches, increased skin irritation (if snorted), increased blood pressure, kidney stress (due to processing by the kidneys), liver stress (as a result of processing via the liver), acne dry skin, premature balding, greasy hair loss, jaundice.

Oral Metribolone dosage is 200-500mgs/week, injections are normally injected every 5 days at a dosage of 250mg. More experienced users have been known to take up to 1gram per day for extended periods of time.
Types of Metribolone
Metribolone can be obtained in both oral and injectable forms. The injectable version is the most popular because it has a faster effect and is easier to control (you can’t easily open an oral tablet and divide it into smaller pieces like you would with the powder).
Consult your physician prior to taking this drug
If you have any liver conditions, kidney disease, high blood pressure, enlarged prostate, or glaucoma. Also if you are susceptible to congestive diseases such as hypertension, heart failure, angina, blockage of arteries, or other circulatory problems that might produce similar symptoms.
If you are going to stack Metribolone, the most popular bulking stacks use Equipoise and Deca-Durabolin. You can also add Dianabol or Anadrol 50 in place of metribolone for a faster cycle.
orals -Dianabol, Testosterone, Parabolan injectables – Deca Durabolin, Equipoise, Mastisol, Sustanon.
Stacks with Primobolan and Winstrol, HGH can be used in limited amounts due to its mild effects. Adding T3 or Clenbuterol will make the cycle more effective at increasing muscle hardness and density without adding too much water retention. It is often used during the last 2-3 weeks before a bodybuilding competition.
Cycling & Stacking
Metribolone can be effective when used for between 8 and 12 weeks at dosages of 100mg every day. The drug should not be taken for more than 12 consecutive weeks. Some users take lower dosages (50-75mg per day) but with longer cycles (12-16 weeks). It stacks well with most anabolic steroids, particularly testosterone, Equipoise, nandrolone decanoate, trenbolone acetate, boldenone undecylenate, Halotestin, Anadrol 50, Primobolan Tablets, Winstrol Tablets.
Metribolone in medicine
Although methyltestosterone is the active metabolite of metribolone, and this may be one reason for its reduced progestational activity relative to that of oral testosterone, such has not been demonstrated in clinical trials. It is therefore unlikely that metribolone would possess much if any activity as a progestogen.
The side effects mentioned above are common with many steroids and especially those compounds containing heavy metals such as aluminum or cadmium. This is why it is very important to use only pure ingredients which do not contain impurities left behind from the manufacturing process. When using injectable metribolone you should also try to find products that are oil-free, since oil-based suspensions can cause severe acne which is very difficult to get rid of.
Metribolone in bodybuilding
To date, there are no known cases of athletes testing positive for metribolone or coming under investigation by anti-doping agencies such as the USADA. This is most likely due to the fact that metribolone has been around for only a relatively short time and the drug appears too harsh for athletes’ use. In addition, an efficacy study performed on rats showed that repeated administration of methyltrienolone over 28 days leads to a reduction in the weight gain of muscle tissue despite increased muscular gains during their training phases. Metribolone is, therefore, most probably not suited for long-term application with continuous use leading to a decrease in its anabolic activity.
It should be noted that due to the rapid clearance of methyltrienolone, long-term administration studies are very difficult to conduct. It is possible that longer-term use would yield different results. However, it is more likely that any changes would not be significant or universal enough to warrant its usage over short periods only (i.e., 6-8 weeks) unless perhaps at low doses (15mgs/day) for the purpose of maintaining normal sexual function in older males with age-related low testosterone levels. This application, however, has yet to be studied clinically and therefore remains theoretical at this time.
There are other progestagens that possess no intrinsic androgenic properties but which might antagonize the androgenic action of methyltrienolone if given together. Such progestagens include nomegestrol acetate, medroxyprogesterone acetate, megestrol acetate, cyproterone acetate, and chlormadinone acetate.
Alternatives to Metribolone
Due to the fact that very little is known about methyltrienolone, it should not be used for physique- or performance-enhancing purposes. If you are looking for very strong anabolics then we recommend trying the following compounds instead:
- Omnadren – a mixture of four testosterone esters 350mg/ml
- Trenbolone Mix – blend of 3 esters 100mg/ml
- Drostanoloneone Mix – blend of two esters 100mg/ml
- Insulin Mix 75 – contains three fast-, intermediate- and slow-acting insulin substances 75iu each
- Nandrolone Decanoate 200mg/ml 10cc amps 50mgs/ml
- Deca Durabolin – a mix of three esters 100mg/ml
- Parabolan – Trenbolone Hexahydrobenzylcarbonate 100mg/ml
- Winstrol Mix – blend of two esters 50mgs/ml
As always, the best advice is to consult a doctor before using this or any other supplement.
In most cases, growth hormone does not cause acromegaly so long as the amount of GH in circulation is very low and pituitary somatotroph cell function has reached maturity. It is certainly possible for a bodybuilder to experience acromegaly from exogenous administration of GH but it would appear that this is exceedingly rare in healthy athletes who have never received treatment with somatotroph-stimulating pharmaceuticals.

Risks when using metribolone
When used correctly and responsibly, metribolone can be a powerful steroid for increasing strength and muscle mass. However, it comes with many risks that should never be taken lightly especially when the drug is being used without medical supervision. Some of these potential side-effects include:
heart problems such as high blood pressure
liver damage – c17alpha alkylated compounds are toxic to the liver
reduction in HDL cholesterol levels – raises LDL cholesterol levels which can increase the risk of cardiovascular disease
acne – caused by the compound’s effect on hormone levels which causes excessive production of sebum oil by the skin
increase in prostate size – due to increased DHT binding to androgen receptors in the prostate; prolonged or high exposure
Why do you need metribolone?
Metribolone is one of the most powerful anabolic steroids ever produced. This is due to its very strong binding affinity for androgen receptors which makes it very effective in promoting muscle growth even when dosages are low. Based on its high affinity, metribolone can produce large increases in strength within a short period of time, usually between 6-8 weeks after administration begins.
Because metribolone binds so tightly to androgen receptors it can activate receptor-mediated functions without having to convert into dihydrotestosterone (DHT). The result is that metribolone itself has direct effects on various target organs like the skeletal muscles but does not significantly affect other organs like the prostate gland or skin.
The lack of DHT means that metribolone does not cause the severe side effects associated with other anabolic steroids that are usually a result of high levels of DHT binding in androgen-sensitive tissues.
Is it good for beginners?
Being a modified version of the potent anabolic steroid trenbolone, metribolone is not recommended for beginners. Metribolone is one of the most powerful steroids ever produced and some have described it as being 10 times more powerful than trenbolone. It can produce dramatic increases in strength within just 6-8 weeks which is one reason why it has become so popular among bodybuilders despite its high risks.
It takes time before your body becomes accustomed to taking this drug so you should only take small dosages during your first cycle or two. Since there are no official guidelines regarding how long someone has to be using the drug before they decide if their body has built up a tolerance, it would be wise to err on the cautious side and limit use to no more than two months.
What are the differences between trenbolone and metribolone?
Trenbolone is basically a modified version of methyltrienolone (17-alpha-methyl-19 nor testosterone) which means that it shares many similarities with metribolone. However, there are some differences to consider.
‘Methyltrienolone 17-alpha-methyl-19 nor testosterone’
Being a small ester-based steroid, trenbolone has a short half-life and needs to be taken once or twice a day so you might want to take it in two equal dosages per day for best results. This drug works well when stacked with other steroids but if you’re taking high doses then the risk of side effects becomes greater so liver protection supplements should be considered regardless of how much you are taking.
Being a long ester base steroid, metribolone produces steady blood concentrations of the compound so it does not need to be taken more than once or twice each week. A lot of people stack this drug with other anabolic steroids and they often prefer injecting it as opposed to oral administration since there is less likelihood of liver damage. However, as mentioned earlier, metribolone is one of the most powerful steroids ever produced and some have described it as being 10 times more potent than trenbolone. Because of its high potency and strong binding affinity for androgen receptors which makes it effective in promoting muscle growth even when dosages are low, the risk of side effects can become very high. Since it’s not liver protective you should only take small dosages during your first cycle or two.
Is metribolone effective?
The fact that this steroid produces dramatic increases in strength within just 6-8 weeks is one reason why it has become so popular among bodybuilders despite its high risks. Many people have reported seeing dramatic gains in muscle mass and strength when injecting metribolone at a 5mg dosage two to three times each week.
