That double bond is also responsible for Boldenones resistance for being changed by the 5- 5-Alpha-reductase enzyme (2)(3). This enzyme converts a small amount of Boldenone into Dihydroboldenone, which is a very potent androgen (7x as anabolic as testosterone)(4). As I said though, such a small amount of it is converted that its really of no concern to most athletes taking Boldenone. This factor, plus its low aromatization rate mean athletes don’t need to consider using ancillaries with Boldenone.

Athletes taking Boldenone often report a slow and constant buildup of quality muscle, and certainly this has been my experience with the drug. I would speculate that this slow buildup of muscle is due to the very long ester attached to the Boldenone; Undeclynate is a longer ester than the decanoate ester by one carbon. Thus, we could expect the accumulation of muscle from Boldenone to actually occur at a slightly slower rate than that found with Deca (nandrolone decanoate). This leads me to advise that if you are considering the use of Boldenone, you should consider using it for no less than 12 weeks. Boldenone, like Deca, is also detectable in your system for a long time (although it is substantially less than Deca’s detection time).

Strangely, shorter estered versions of Boldenone are available as well. Anecdotally, many people (and manufacturers) claim that this produces less water retention…but water retention from Boldenone is virtually unheard of, so I consider this to be a silly idea.

Ideal dose of Boldenone at 600mgs/week. Most people I asked about their Boldenone experience with Boldenone seemed to think that using over 600mgs/week produced no additional results, but the jump from 400mgs/week to 600mgs/week produced noticeable additional gains, and thus was warranted. I have personally found very nice results from 400mgs-600mgs/week myself.
