BOLD-250  (1,4-androstadiene-3-one-17β-ol) is available as the undecylenate esters and is an anabolic steroid. The activity of BOLD-250  is mainly anabolic, with a low androgenic potency. It has a very long half-life, with minimal blood levels present up to 8 weeks after discontinued use. Boldenone undecylenate is considered to be a long-lasting anabolic steroid, with effects persisting for up to 8 weeks. Boldenone is recommended when an improvement in weight, hair, or general physical condition is desired.

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

SIDE EFFECTS: Although commonly compared to nandrolone, boldenone lacks 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. BOLD-250  does reduce to a more potent androgen dihydroboldenone via 5 alpha-reduce enzyme, however it is 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 associates with Boldenone. Boldenone is also known to cause anxiety and flu like symptoms which manifests themselves most acutely in short ester versions like: acetate, and propionate (almost unusable), but which are also present in the enanthate, cypionate

PREGNANCY: not to be used in pregnancy. BOLD-250  has been reported to cause a determinal effects in testicular size, sperm production and quality. In mares, fewer total and large follicles, smaller ovaries, increased clitoral size, shortened estrus duration, reduced pregnancy rates and severely altered sexual behavior have been noted.


DRUG INTERACTIONS: there are no interactions with medications listed specifically for boldenone, however anabolic agents as a class may potentiate the effects of anticoagulants and decrease blood glucose levels.

INDICATION: As an anabolic steroid. Certain cases of disseminated breast cancer in woman. Osteoporosis due to androgen deficiency in hypogonadal males.

STORAGE: store at room temperature below 25̊ C.
