Boldenone Equipoise (Undecylenate) is an effective anabolic steroid to increase your muscle mass. Compared to other steroids, the chance of gynecomastia is much smaller and you retain less or no fluid during a course. In addition, boldenone is less liver toxic than other steroids. This makes boldenone almost as effective as nandrolone, but a lot safer.

Features boldenone
Boldenone only exists as an injectable solution. After injection, it continues to work actively in your body for 14 to 16 days. Unlike many other anabolics, boldenone is not harmful to your liver. Other features:

  • Moderate aromatization
  • Low fluid retention
  • Low DTH conversion
  • Moderate suppression of natural hormone production

How does boldenone work?
Boldenone dramatically increases the number of androgen receptors. In addition, boldenone increases nitrogen retention in your muscles. As a result, your muscle cells retain more proteins. The result is faster muscle growth. A small portion of boldenone aromatizes to estrogen. This increases the storage of glycogen and the release of growth hormones which also creates more muscle mass.

Boldenone has few estrogenic side effects and is a lot safer compared to nandrolone or deca. That's because only a small portion of boldenone aromatizes.
Who is boldenone suitable for?

Boldenone can be used for different purposes. For example for bulking or cutting because in both cases it provides an increase in muscle mass without high fluid retention. Below are more examples of situations in which boldenone is highly preferred.

Develop greater stamina
Boldenone stimulates the production of the hormone EPO. This hormone increases the production of red blood cells. Red blood cells improve endurance. For that reason, boldenone is very popular with endurance athletes and bodybuilders while cutting.

Women who want more muscle mass
Boldenone is also loved by women. That's because it almost never causes masculinization of the body. Women always use boldenone in a lower dose than men.

bulk cycles
Boldenone ensures an increase in muscle mass because it ensures that your muscle cells retain more proteins and boldenone almost does not aromatize. In addition, boldenone increases the appetite, which is very beneficial if you want to build more muscle mass. Thanks to the increased appetite, boldenone is very suitable for use in a bulking cycle alongside long testosterone esters such as testosterone, enanthate or cypionate.
It is wise to do a 4-week follow-up course with novaldex or clomid after a bulk cycle with boldenone. Start this 2 weeks after your last boldenone injection.

Cut cycles
Boldenone is also suitable for cutting cycles because it has low fluid retention and increases vascularity. The risk of gynecomastia is also very small because it does not bind to the progestarone receptors. You can easily stack boldenone with wintrol, testosterone propionate, trenbolone acetate or parabolan.

Side effects boldenone in brief
The side effects are a lot milder compared to other steroids. Because boldenone does have a slight influence on hormone production, the following side effects can occur:

  • Shrinking testicles
  • Temporary erectile dysfunction
  • Increasing body hair
  • More acne and oilier skin
  • High bloodpressure
  • Decrease good cholesterol
  • Mild degree of gynecomastia
  • Slight degree of masculinization in women (only at high dose).

Boldenonene-based cycle

Use boldenone for at least 12 weeks as it is a long-acting anabolic. A normal dose is about 500 milligrams per week. For men, the minimum of 400 milligrams and the maximum of 800 milligrams per week applies. Women should opt for a lower dose of 50 to 150 milligrams per week. Boldenone is suitable for bulk and cut cycles.
