However, due to its effects, the drug became popular among bodybuilders and athletes. Today, Equipoise is widely used in bodybuilding, powerlifting and other strength sports (in order to build muscle mass). The substance is considered to be very reliable and safe.

Equipoise has a relatively strong anabolic effect combined with moderate androgenic properties. The drug has a beneficial effect on the body’s metabolism, that is, it works to increase protein synthesis in the muscle cell.

Equipoise is widely used in preparation for competitions. Athletes combining Equipoise with injectable Winstrol talk about excellent muscle elasticity and density. Such combination provides rapid growth of quality muscles (if combined with high-calorie and high-protein diet). Many athletes are also convinced that Equipoise stimulates appetite.

Properties of Equipoise (Boldenone Undecylenate)

Boldenone Undecylenate is very similar to Methandrostenolone (Dianabol). It is almost identical to Methandrostenolone in terms of chemical structure. However, its action is different. Dianabol is known for its ability to build muscle faster. Equipoise is a steroid known as an excellent agent for the cutting phase. Moreover, Equipoise is extremely long acting steroid. It stays in the body for weeks and sometimes even months after the last injection. Meanwhile, Dianabol is removed from the body within a few days.

Dianabol is taken orally, while Equipoise slowly dissolves in the body after injection. Few people know that in fact Equipoise is an injectable version of Methandrostenolone. The only difference is that Boldenone is characterized by the absence of a methyl group due to some changes in the chemical structure.

In recent years, Equipoise has gained enormous popularity as a good analogue for Deca Durabolin. There are many structural differences between these drugs, but they are very similar in their properties. Both steroids help gain clean muscle mass with mild side effects.

However, Equipoise acts slower and almost does not lead to fluid retention. Mild side effects help Equipoise successfully compete with Deca Durabolin. They have very similar anabolic properties, but Equipoise has fewer side effects than Deca. For this reason, Boldenone Undecylenate is a very popular steroid for solo cycle users and for combination with other anabolic steroids (AAS).

Boldenone helps increase muscle mass and strength slowly and gradually. Due to the low level of water retention (as opposed to Methandrostenolone), your muscles will be kept in shape for a long time.

Boldenone Undecylenate is a fat-soluble ester with significantly prolonged action. Like other steroids, Boldenone cycle increases protein synthesis and nitrogen accumulation in muscle tissue. Also, it helps increase the number of erythrocytes and improve the oxygen supply to the muscle fibers.

Boldenone therapy does not lead to a sudden weight gain in a short time. The effect may be different depending on the dosage, nutrition and training. When using the drug with the low-carb diet, you can gain about 5 kg within a few weeks. If the main goal is to gain more weight, you need to increase the dose and follow a high-carb diet. In this case, you can gain up to 7-9 kg within a 5-week course.

The drug can be very useful in combination with other steroid agents (both for weight gain and for the cutting phase), because it will help maintain most of your lean muscle mass.

Moreover, Equipoise can be used for a long period of time, which is essential for slow process of muscle building.

Equipoise dosage

Boldenone is popular among both beginners and more experienced athletes. The optimal dose ranges from 300 to 500 mg per week. The weekly dose can be divided into 2-3 doses. Experienced athletes who have already tried many steroids may use up to 700-1000 mg weekly (without the risk of adverse reactions).

In particular, to gain better results in muscle mass, it is recommended to use Boldenone in combination with various esters of Testosterone or Oxymetholone. As for the cutting phase, the best choice is a combination with Masteron, Winstrol or Oxandrolone.

As for women, they also respond well to Equipoise. When taking 50-100 mg weekly, it is possible to achieve better muscle growth with little water retention. Higher dosages can cause virilization phenomena: deepening of the voice, acne, increased libido, and in rare cases increased hair growth on the face and legs.

Equipoise (Boldenone Undecylenate) for muscle mass

The anabolic activity of Equipoise is the same as that of Testosterone, whereas the androgenic activity is 2 times lower. Nevertheless, Equipoise is a relatively weak steroid, since its effect is less pronounced (Boldenone effects are lower compared to the same amount of Testosterone).

This drug significantly increases strength and endurance, although it helps gain muscle relatively slow. Boldenone improves hematopoiesis, which has a positive effect on muscular endurance. It is also important to know that Equipoise helps increase appetite. This is extremely important for people who can’t eat a lot. This is one of the properties, which makes it attractive for mass gaining cycle. It is well combined with almost all steroids. In this way, Boldenone can be combined with long Testosterone esters such as Enanthate, Cypionate, or Sustanon.

Boldenone is used both for muscle growth and for the cutting purpose. Usually beginners start with a dosage of 400-600 mg per week for, while experienced athletes – with 600 mg per week or more.

Equipoise (Boldenone Undecylenate) in cutting cycles

Boldenone is great for the cutting phase. It has a high anabolic activity that does not allow cortisol destroy your muscle tissues. It should be taken into account that Equipoise is good for the summer and beach season. It is not used during precompetitive period.

Equipoise (Boldenone Undecylenate) solo

Many athletes prefer to use Boldenone solo: 600-800 mg per week for 8-10 weeks. As for PCT, they take Tamoxifen or Clomid (usually if the dosage of Boldenone is higher than 800 mg). The post cycle therapy may also include testosterone boosters.

Boldenone solo will definitely bring some results, but they will be much less pronounced than the effects from combination therapy.

Equipoise (Boldenone Undecylenate) Post cycle therapy (PCT)

Just like most anabolic steroids, Equipoise has a very strong impact on the natural production of testosterone. Therefore, due to the fact that Equipoise cycle is very long (14-16 weeks), athletes should use Clomid to maintain hormonal balance and avoid sexual dysfunction.

Equipoise (Boldenone Undecylenate) side effects

Due to the fact that Equipoise aromatizes very poorly, unwanted side effects are extremely rare. Some of them may bother you in case if you take high doses of the drug. Also, there may be some side effects of androgenic nature: oily skin, acne and hair loss. Yet, these side effects are usually associated with large amounts of Boldenone Undecylenate. Besides, Equipoise is not toxic to the liver.

Another side effect associated with Equipoise is that the drug may cause an increased appetite and can provoke strong food cravings. Although this is not a threat to health, such symptoms can be a challenge for those in the cutting phase. In such cases, it is recommended to use lower doses of Equipoise.

There are no absolute contraindications for men. Excessive formation of estrogen in men may lead to gynecomastia, peripheral edema and periodic increase in blood pressure (rarely).

As for women, it is not surprising that Equipoise is very popular among female athletes who use it in low doses. Female bodybuilders usually use 25-50 mg per week. This dose gives significant results and makes the therapy relatively safe. Some women use 75 mg weekly. In this case, the drug should be taken with extreme caution because of high risk of virilization. However, once you begin to suffer from symptoms of virilization, Boldenone Undecylenate should be immediately discontinued.


Equipoise is a steroid that can be used both solo and in combination with other anabolic agents. Basically, it helps gain lean body mass and strength.

Due to the fact that Equipoise has very similar properties with Deca Durabolin, these drugs are often compared to each other. The biggest difference is that Equipoise has fewer side effects.

In general, we can say that this is a very safe steroid that gives more than adequate results. In this way, Equipoise is one of the most popular steroid agents among female athletes.
