Boldenone is the most popular steroid for veterinary use. It has a very high level of male hormone and acts actively in synthesis. Boldenone is effective and stable in promoting the muscle and strength growth. If it is taken with other drugs, its pharmaceutical effect would be better. Boldnlone enjoys great popularity as a steroid which can keep the muscle after the cycle (Trenbolone, stanozolol, testosterone, pure HGH have the same effects). Besides, human body has a little boldenone under the natural situation. Boldenone was synthesized in an attempt to create a long-acting injectable methandrostenolone (Dianabol), but as a matter of fact boldenone does not have the characteristics of methandrostenolone at all. It has a very long 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. The ttrace of 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 progestogenic side effects.
