Boldenone Undecylenate is classified as an anabolic steroid exhibiting less androgenic activity than its analogue testosterone. It is a highly anabolic, moderately androgenic steroid. It has a very favorable effect on the organism's nitrogen balance so that the main effect consists of a distinctly increased protein synthesis in the muscle cell. Boldenone was actually created while attempting to make a product which would be be a long acting injectable methandienone(D-bol). What was actually created was a product which, in the real world acts nothing like D-bol, despite it's similarity to it chemically. A simple way to think of Boldenone, chemically at least, is simply as methandienone without the 17-alpha-methyl group (that's the thing which makes methandienone able to be ingested orally and not be destroyed by your liver). However, having had first hand experience with both Boldenone as well as D-bol, we can tell you that the results from each are vastly different.To make Boldenone, a double bond was added between carbon atoms 1 and 2 of the Steran Nucleus oftestosterone. What does this mean? Well, first of all, since Boldenone was created by one simple modification in the testosterone molecule, you could rightly suspect that it shares many similarities with it. Boldenone is just as anabolic as testosterone (as you can tell by its anabolic rating above), but only half as androgenic. Those ratings can be quite deceiving though, as I don't know anyone who would claim that you can gain as much weight on Boldenone as you can gain on an equal amount of testosterone (even though strength gains from the two compounds are very similar).
