Dianabol aka Dbol (Methandrostenolone) – Oral Steroid For Bodybuilding Explained

Steroid Name: Methandrostenolone – Dianabol

aka: Metandienone, Dianabol, DBol, Averbol, Danabol, Anabol, Metanabol, Methandon, Naposim, Vetanabol

Forms: Oral and Injectable (as Reforvit-B)

Mostly Used For: Kick starting a Bulking Cycle


Dianabol Anabol TabletsMethandrostenolone, under the first trade name Dianabol is perhaps the most famous oral anabolic steroid, with Winstrol ‘Winny’ (Stanozolol) and Anavar ‘Var’ (Oxandrolone) not far behind.

Its status might be due to it being the first steroid – after testosterone – to be synthesized, and therefore marketed. It might also be down to its reputation for providing results.

Whatever the reason, ‘Dbol’ is a powerful oral anabolic steroid, which binds to the androgen receptor, increasing protein synthesis, nitrogen retention and glycogenolysis.

Structurally, it is based on testosterone, with a few minor changes that make it less androgenic, and more anabolic.

Note that there is an injectable form, known as Reforvit-B, which is fortified with B vitamins.

There are several side effects associated with the use of this steroid, notably; liver toxicity (hepatotoxicity), estrogenic effects, cardio-vascular problems and endogenous testosterone suppression. These will be discussed in more detail later in the article.

Main Benefits to the Bodybuilder / Athlete

As mentioned in the intro, there are 3 main benefits, in terms of physical enhancement, to the bodybuilder:

Protein Synthesis

Dianabol dramatically increases the rate of protein synthesis. This means muscle tissue can repair and grow much quicker than it otherwise would.

There are obvious advantages to the bodybuilder, and while there was once a medical application, it has since been made widely unavailable for this purpose in developed countries due to the potential for adverse side effects.

Nitrogen Retention

Given that muscles have high nitrogen content, their ability to retain nitrogen in high quantities serves to create a more anabolic environment.

If the opposite were true – i.e. a nitrogen deficiency – a catabolic (muscle break-down) state would be in effect.


The conversion – or breakdown – of glycogen to glucose. By enhancing this process, the body can utilize its main energy source more efficiently.

Again, bodybuilders are at an obvious advantage when they can utilize fuel stores and optimize their carbohydrate cycle.

Side Effects of Dianabol

The high probability of negative side effects of anabolic steroids is perhaps the main reason that they have become controlled substances in many countries.

Dbol is no different. Its possible side effects include:


Due to the moderate level of aromatase activity, methandrsotenolone converts to methylestradiol (instead of the more common estradiol).

As such gynecomastia (male breasts) and excess water retention can occur, and can come on fast. Also, the water retention can lead to high blood pressure if left unchecked.

Countermeasures: most people have to use prescription level drugs to counter the estrogenic effects. Anti-estrogenic medication comes in the form of SERMs (Selective Estrogen Receptor Modulators) like Tamoxifen or Clomiphene (e.g. Nolvadex or Clomid) OR Aromatase Inhibitors (AIs) like Letrozole (e.g. Fermara) or Anastrozole (e.g. Arimidex).

AIs themselves have a negative effect on cholesterol levels, so SERMs may be the safer option. They aren’t however as powerful an Anti-estrogenic as AIs are.

Post Cycle Therapy (PCT) drugs, Anti-estrogenics, and other side-effect-countering medications are an important part of the process.To read more about these measures, read our article about them.

Testosterone Suppression

Most anabolic steroids suppress the user’s endogenous (natural) testosterone production to some extent. This is because the exogenous influx of the synthetic steroid – which is itself a derivative of testosterone – tricks the body into thinking there is already far too much.

The severity nevertheless varies from one steroid to another.
Methandrostenolone’s suppressive action is strong, therefore most men take mitigating measures.

Countermeasures: exogenous testosterone is often injected when taking Dianabol. This ensures that the body at least has circulating testosterone and that the unhealthy side effects of low-testosterone will not happen.

This is of course a short term solution, in lieu of the natural recovery of endogenous testosterone. Following the steroid cycle, natural recovery will be slow and may be adversely affected by the shut-down period.

A course of PCT is often required, which will include Anti-estrogenics (SERMs and AIs) and sometimes Human Chorionic Gonadotropin (HCG).

Nonetheless, total natural testosterone recovery can take months.


Chemically speaking, Dianabol is less androgenic than testosterone. However, effects such as accelerated hair loss, acne and body hair growth are still possible.

Important Note: Women should completely avoid this steroid. Masculine side effects are almost guaranteed.

Liver Toxicity / Hepatotoxicity

A major drawback of oral anabolic steroids like this one is their toxic effect on the liver.

To make it through the liver and exert their anabolic effects, Dbol, Anadrol, Winstrol, Anavar and others like them have been chemically altered.

This usually comes in the form of carbon-17-alpha-alkylation. This leaves behind toxic material which could potentially damage the organ, given enough time.

Countermeasures: time is the main problem. Beyond 3 or 4 weeks cycle length and the user is risking real problems.

Other prescription medication should also be avoided as many of them carry hepatotoxic potential themselves.

Of course, alcohol consumption must be completely stopped. If nothing else, someone using steroids and drinking alcohol is needlessly wasting money, time, effort and most importantly their life.

Cardiovascular / Cholesterol

Cholesterol balance can be negatively impacted by using Dianabol. It’s not enough to measure Total Cholesterol as the HDL / LDL balance may be completely skewed and still give a good total result.

Additionally, the excess water retention mentioned earlier in the estrogenic effects may compound the cholesterol problem.

Countermeasures: a healthy diet and general lifestyle are a must. If a user is predisposed to CV problems then they should probably be avoiding all anabolic steroids anyway.

It’s important to note that Aromatase Inhibitors (AIs) mentioned earlier can also negatively impact cholesterol. The double impact of Dianabol and the AI makes SERMs the safer, yet weaker, Anti-estrogenic.

Dosage and Usage

The average dosage of methandrostenolone lies within the 20mg to 50mg per day range.

Generally speaking, it is used to start a bulking cycle. The water retention alone mostly precludes its use as a cutting steroid and it is highly anabolic, leading to bulky mass gain rather than lean mass.

Again, generally speaking, testosterone in the form of a single ester, or a blend like Sustanon 250 is injected alongside to prevent low testosterone syndrome.

Often, other injectables like Deca Durabolin and Trenbolone acetate are used alongside as they have a longer active life in the body and take a few weeks to start taking full effect.

At which point, the Dianabol can be stopped. Since it is quite hepatotoxic, messes with cholesterol and causes several other side effects, it is prudent to stop its use as soon as possible anyway.

Availability – Legality – Purchase

The articles on this site are for educational purposes. In no way do we support or assist the purchase of anabolic steroids, whether it’s white, grey or black market…either via the internet, some shady underground lab or a ‘clinic’.

If nothing else, it is impossible to guarantee that you are getting genuine product.

Additionally, the extensive efforts you must go to in order to prevent the deterioration of your health means that you are quite literally taking full responsibility of your own body. No advice that anyone can give will completely fit your body’s profile.

The law is similar in many countries. Someone possessing steroids for personal use will most likely get a caution at most. The manufacturer and distributor will not be so lucky.

In the US, it is still technically illegal to own any amount, however, and you should be aware of this no matter what other people tell you.

Countries such as Mexico and Portugal have very different laws. However, just because they can sell with impunity does not mean your online purchase will result in a package of clean anabolic steroids being left in your mail box without so much as a whisper from one of the many agencies hell-bent on preventing that eventuality.

Be safe. Be Smart.
