Why buy this product

Boldenone Undecylenate by Transparent Labs USA is used in bodybuilding to increase muscle mass and strength. It can also help improve endurance and speed recovery after workouts.

Boldenone undecylenate has a relatively long half-life, which means that its effects may be noticeable for several weeks after application. This allows bodybuilders to use it on long cycles for maximum results.

Steroid profile of Boldenone Undecylenate

  • substance activity: 15 days;
  • method of application: by injection;
  • anabolic activity: 100% of testosterone;
  • androgenic activity: 50% of testosterone;
  • aromatization (conversion to estrogens): low;
  • liver toxicity: no;
  • effect on the hypothalamic-pituitary-ovarian/testis axis: moderately suppressive.

Effects of taking Boldenone Undecylenate

  1. increase in muscle mass: Boldenone undecylenate can increase protein synthesis in muscles, which can lead to an increase in their volume;
  2. Endurance Improvement: This steroid can increase blood flow to the muscles and improve their oxygen supply, which can increase endurance during training;
  3. Accelerated recovery: Boldenone undecylenate can reduce recovery time after workouts, reduce muscle pain and improve overall body condition;
  4. Appetite Improvement: This steroid can increase appetite, which can lead to increased muscle gains;
  5. improved bone density: Boldenone undecylenate may increase bone density, which may reduce the risk of osteoporosis.

Application and dosage of Boldenone Undecylenate

Novice athletes should not enter more than 400-500 mg of Boldenone during the week. Experienced bodybuilders may take up to 800 mg over a similar period of time. For female athletes, the weekly dose is a maximum of 100 mg. The duration of the courses is within 2-3 months.

Combined course of Boldenone Undecylenate

To gain muscle mass, athletes combine Boldenone with Trenbolone or Enanthate. This course is the most appropriate for beginner bodybuilders, as it corrects the anabolic and androgenic effects. In addition to Testosterone and Boldenone, undecylenate is also recommended to be used with Clomid, which excludes the possibility of developing estrogen side reactions.

As an example, consider the scheme for using the Sustanon - Boldenone ligament:

  • put sustanon twice a week, 250 mg;
  • the frequency of boldenone injections is also 2, and the single dose will be 200 mg;
  • the duration of the course can be limited to 8 weeks;
  • to eliminate the negative effects of a mix of Testosterone esters, add Letrozole to the course. Start taking this aromatase inhibitor from the second week, taking every second day at 0.5 mg;
  • after completion of the course, rehabilitation therapy is carried out. Clomiphene Citrate is perfect for this. Take 50 mg of this antiestrogen every day for 3 weeks.

PCT after a course of Boldenone Undecylenate

PCT can be started 14-16 weeks after the last injection. Experienced athletes recommend taking Tamoxifen or Clomid for 2-3 weeks.

There are reports from people suggesting that the most effective dosage is in the range of 200mg to 900mg per week, however the optimal dose is 400-500mg per week. Some have experimented with higher dosages, but this is not highly recommended due to the risk of side effects.

Side effects

  • suppression of one's own testosterone and disruption of the reproductive system;
  • acne, baldness, gynecomastia and other manifestations of virilization;
  • increased blood pressure and cholesterol;
  • allergic reactions to the oil base of the drug.

Therefore, it is not recommended to use Boldenone Undecylenate without consulting a doctor or trainer. It can be hazardous to health and career.

What other drugs will affect Boldenone Undecylenate

There are several drugs that can interact with boldenone undecylenate. Some of them may increase the risk of side effects, while others may reduce the effectiveness of the steroid. Here are some examples of such drugs:

  • Antiestrogens: such as tamoxifen or anastrozole can help prevent the development of gynecomastia, an enlargement of the breasts in men.
  • Other anabolic steroids: The simultaneous use of several anabolic steroids can increase their effect, but also increase the risk of side effects.
  • Hepatoprotectors: designed to protect the liver from the negative effects of anabolic steroids.
  • Drugs that increase prolactin levels, such as domperidone or bromocriptine, can lead to hyperprolactinemia, which can increase the risk of gynecomastia and other side effects.
  • Cholesterol-lowering drugs: such as statins or fibrates, may increase the risk of cholesterol-lowering side effects.
