The drug is a chemically synthesized testosterone, in the chemical chain of which the first and second carbon atoms are linked. Bondenone is twice as active as testosterone. Comparison of the drug with nandrol is unreasonable due to the difference in their effect on the athlete's body.

Boldenone has a greater correspondence to testosterone than the second drug. Taking the Steroid can be in different forms. (Buy Boldenone UK)  With the same exposure, the difference is observed only in time intervals.

Boldenone undecylenate - belongs to the group of anabolic steroids with androgenic action of the average level, dissolved in oil with an undecylenate ester (1,4-androstadien-3-one, 17b-ol 1-dehydrotestosterone) attached through the 17-beta hydroxyl group; half-life in the human body is of the order 9-11 days (full working life up to 15 days), the chemical formula of the base is C11H20O2.

Boldenone Undecylenate is a modified form of testosterone. The difference between these substances is that boldenone undecylenate has a double bond between the 1 and 2 carbons, which helps to reduce estrogenicity and androgenicity. Unlike free steroids, esterified steroids are not absorbed as quickly from the injection site, and they are also less polar. After the ether enters the circulatory system, it is split off and free boldenone is found in the blood.

The aim of the development of esterified steroids was to prolong the therapeutic effect of injections, to reduce the frequency of injections in comparison with free steroids. To ensure the release of boldenone on a high crown for a couple of days and a sustained release of the hormone over a couple of weeks, it was decided to develop boldenone undecylinate. It is important to note the structural similarity, almost identity of boldenone and methandrostenolone.
