Side effects from the use of Boldenone undecylenate are pretty low when it is taken in normal (200-400mg/week) dosages and estrogenic side effects only occur in those who are very susceptible to estrogen. In terms of androgenic side effects, long term or high dose use, can result in slight virilizing effects including acne and increased body hair growth.

Low androgenic level allow women to use it.

The phenomenon of virilization is very rare effect compared with others steroids.

Boldenone- is one of the rare injection steroids with low risk of side effect.

The double connection between 1st and 2-nd carbon atoms provides resistance of boldenone to enzyme 5-alpha-reductase.

This enzyme converts a small amount of boldenone into dihydroboldenone, which is a very potent androgen (7times more anabolic than testosterone). That why it has so low level of androgenic side effects like baldness, acne prostatic hypertrophy and etc. and also less suppresses the production of testosterone in the body.


After cycle therapy start when 14-18 days pass, after the last injection. It’s simple, use some antiestrogen with gonadotropin to stimulate the production of your own testosterone.
