Boldenone
 

The activity of boldenone is mainly anabolic, with a low androgenic potency.

Boldenone will increase nitrogen retention, protein synthesis, increases appetite and stimulates the release of erythropoietin in the kidneys.

Boldenone was synthesized in an attempt to create a long-acting injectable Dianabol (Methandrostenolone), but in reality Equipoise acts nothing like Dianabol. The muscular gains made on a Boldenone cycle are usually slow and steady, resulting in quaility sustainable muscle, whereas Dianbol is a faster acting steroid designed for immediate weight gain. Another reason Boldenone is so popular for bulking is because it increases the appetite; this is also a reason many athletes will stay away from it pre-contest.

Boldenone has a low rate of aromatization (about 50% of Testosterone), which means it does not convert to estrogen easily and does not cause very much water retention.

It has a very long half-life, and can show up on a steroid test for up to 1.5 years, due to the long undecylenate ester attached to the parent steroid. Trace amounts of the drug can easily be detected for months after discontinued use.

Although commonly compared to nandrolone, boldenone lacks progesterone receptor interaction and all the associated progestinic side effects. Boldenone can, however, produce mild androgenic side effects. Oily skin, acne, increased aggression and hair loss are all possible with this compound but rare. Boldenone does reduce to a more potent androgen dihydroboldenone via the 5-alpha-reductase enzyme (analogous to the conversion of testosterone to dihydrotestosterone (DHT), however its affinity for this interaction in the human body is low to nonexistent. Suppression of the HPTA, water retention, possible increase in acne and possible conversion to estrogen, high blood pressure are all side effects associated with Boldenone.

Boldenone is often used by bodybuilders in both off-season and pre-contest. Boldenone is well known for increasing vascularity while preparing for a bodybuilding contest. If intended to assist in bodybuilding, the drug is taken as part of a steroid stack of other anabolic steroids, usually with a potent androgen like testosterone as the 'base' of the stack.

Common bodybuilding doses range between 200 mg to 400 mg/week but could be as high as 800 mg/week. The medical advised dosage is 1mg per kilogram of bodyweight every 2-3 weeks.

Many bodybuilders will find that it is a good replacement drug for Nandrolone.
