To this day, we have analyzed a large number of modern literature, studies and scientific papers; and we received quite unambiguous and credible information from them. In this article we will try to provide a list of the best steroids, characterize them objectively, and give clear criteria when and how to choose a steroid.

Analysis of the data indicates that new safe steroids don't exist. Do not believe the advertising - many old  steroids are much better than the new ones. This is explained simply - in the 20th century, the steroids studies were much better financed than they are now. Currently, studies are financed not to get more powerful and safe anabolic steroid, but to make it impossible for determination in tests.

Best steroids for muscle mass gaining

Testosterone (enanthate, cypionate)

Testosterone (in injectable form)  is a major anabolic steroid, which is included in a base substantially of all cycles and complexes. Testosterone is used for both muscle mass gaining and weight losing and relief effects, although a certain type of testosterone is preferred in each case. So it is preferable to use enanthate and cypionate for muscle mass gaining, while to reduce fat propionate is a better choice. Testosterone is converted into estrogen and can cause abnormalities in the hypothalamic-pituitary-testes axis, that’s why it should be used with caution.

Methandrostenolone (Dianabol)

World's most popular steroid - methandrostenolone, also known as Danabol (Dianabol). Today, you can find a lot of critical information in respect of the drug, however, from an objective point of view, Dianabol remains the best to this day. Many of this drug’s drawbacks can be completely eliminated if it is used correctly. Dianabol quickly and effectively increases muscle mass, however, there is a pronounced rollback phenomenon of results, moderate toxicity and conversion to estrogen.


The drug for oral taking, it is similar to methandrostenolone in its chemical structure, but the added chlorine atom prevents aromatization. This means that Turinabol does not cause estrogen side-effects (fluid retention in body, gynecomastia etc.). Turinabol high doses are toxic for the liver, so it is often used in combined courses. Currently, a lot of fakes can be found.

Nandrolone (Deca, Retabolil)

Nandrolone Decanoate, better known in bodybuilding as Deca Durabolin or Retabolil, is a leader in many aspects among anabolic steroids. Currently, Deca Durabolin - is the best anabolic steroid for muscle mass gaining. It is characterized by high efficiency, relative safety, low androgenic activity, slight rollback phenomenon, aromatization absence and low toxicity. Deca Durabolin can be used as a single drug, and be included in combinations. Deca Durabolin often causes erectile dysfunction during the cycle, which is associated with decreasing DHT levels by feedback mechanism.

Oxymetholone (Anadrol, Anadrol)

This anabolic steroid is one of the most powerful in its ability to increase muscle mass and strength;  any drug can not be compared with it. At the same time, Anadrol has pronounced side effects: liver damage, hypertrophy of the heart muscle, disorders of hormonal balance and others.  Side reactions are especially pronounded when the recommended dose or cycle duration are exceed.

Sustanon 250

Sustanon is a mixture of different testosterone esters. The uniqueness of this drug is that separate esters are absorbed at different rates. Thus, Sustanon injections are introduced less frequently.


Trenbolone is testostosterone derivative, in which 3 additional combinations are added to prevent the drug conversion in estrogen and dihydrotestosterone. Chemically drug is like Retabolil, but has higher androgenic activity. Trenbolone is about 4 times stronger than Deca Durabolin, at the same time it has a significantly greater incidence of side effects. Trenbolone has the unique ability to increase the level of insulin-like growth factor, that also has anabolic activity; and also it increases the sensitivity of receptors to it.

Boldenone (Equipoise)

Powerful anabolic steroid with relatively low androgenic activity. Equipoise increases protein synthesis, causes significant muscle mass gaining, stimulates the formation of new red blood cells. Equipoise stimulates the appetite much stronger than other anabolic steroids. The drug was created as an injectable methandrostenolone form, but it was determined that it affects differently. Muscle mass, gained during Equipoise taking is maintained much better, with no significant water retention in the body. Equipoise has a low level of aromatization (50% lower than testosterone).

Best steroids for relief

Oxandrolone (Anavar)

It is one of the safest anabolic steroids. Advantages and distinctive features of Anavar are in its mild anabolic effect, low toxicity and low androgenic effect. Anavar, at recommended doses, hardly disrupts the work of hypothalamic-pituitary-testes axis, does not require the use of antiestrogens and PCT.

Stanozolol (Winstrol)

The popular steroid that is used only during the cutting phase. Winstrol is not recommended for mass increase, because, despite the fact that the steroid has the ability to accelerate the synthesis of protein, it has no pronounced effect on the muscle mass. Winstrol can be considered as a cheap substitute of Anavar. Winstrol is toxic for the liver. It should be noted that the tablet form of the drug has a lower efficiency and at the same time is more toxic, so it is better to use an injectable form. Winstrol increases power rates and venous visibility.

Testosterone propionate

It is one of testosterone esters, used mainly for cutting. Among the drawbacks - there is the necessity of frequent injections, as well as their painfulness.


Its high affinity for the androgen receptor, as well as the ability to increase the level of insulin like growth factor allows to use trenbolone not only as an anabolic agent for the muscle mass gaining, but also for fat burning.

Drostanolone (Masteron)

It is anabolic steroid with androgenic effect, so it often causes side effects. It is used for relief appearing before the competition. Masteron is similar in properties to dihydrotestosterone, and promotes muscle compaction due to diuretic effect. This drug is not recommended for amateur athletes.

Top steroids to increase strength

Oxandrolone and Stanozolol are recognized as the best steroids for strength increase. These drugs can significantly increase the power rates, with little influence on the body weight. If you want to gain muscle mass, the course can include testosterone or trenbolone drugs.
