Side Effects of boldenone undecylenate (boldenone prohormone):
There are some risks. The hormone has the ability to quickly increase the count of red blood cells. Though this is often a feature of anabolic steroids that is well known, the intensity is greater with this one. Similarly an increase in appetite too may not always be welcome. Other problems faced by users have been the formation of acne, development of oily skin, suppression of endogenous testosterone that may lead to sexual dysfunction. There can be growth of body hair as well. Voice may get altered and at times there can also be hair loss. It is therefore better to not take this hormone by itself but combine with something else.
As long as you are within the dosage prescribed, the side effects are minimal and women in particular need not worry about gynecomastia. Women may experience altered libido and notice enlarged clitoris along with a change in their menstrual cycle.
The above side effects are more pronounced when dosage is in excess. More red blood cells lead to viscous nature of the blood which can over time lead to clotting. This can bring about the danger of strokes and a general weakness within the circulatory system. It is more dangerous in athletes who are already prone or have plaque buildup in their cells.
Dramatic increase in appetite may not always be beneficial for everybody and especially those who are not used to heavier cycles. It can work for body builders who consume a lot of calories for mass building and need a stimulant like boldenone to boost appetite.
