Dynabolon (Nandrolone Undecanoate)

Dynabolon is a very unique nandrolone ester, produced only in Italy (the French version was recently discontinued). This particular compound is nandrolone undecanoate, the same ester that Organon uses for their testosterone preparation Andriol. Here the compound is obviously not intended for oral administration however, instead the design being that of a long acting, oil based injectable. The undecanoate provides an active duration of approximately three to four weeks, very similar than what is expected with Deca-Durabolin®. The undecanoate ester is actually one carbon atom longer, making Dynabolon slightly slower to release than Deca. Athletes however, usually inject both in weekly intervals.

This steroid is obviously quite similar in appearance to Deca. It is noted for being an effective anabolic, while not giving the user an excessive level of side effects. Estrogen conversion is slight with nandrolone; so related side effects should be minimal. While water retention is sometimes reported when taking this drug, an actual smoothness and bloating to the muscles would be very uncommon, just as we expect with Deca-Durabolir. Gynecomastia is also a rare concern, but can be a problem with individuals very sensitive to the effects of estrogen. In order to minimize such side effects, an ancillary drug like Nolvadex® and/or Proviron® could be added if absolutely necessary.

It is also of interest that nandrolone undergoes the same conversion process that changes testosterone into dihydrotestosterone, a more potent androgenic metabolite. But the result with nandrolone is dihydronandrolone, a much milder hormone. DHN is in fact miler than its parent nandrolone, which means that the activity of the steroid will actually be reduced in tissues with a high concentration of 5-alpha reductase. Androgenic side effects will therefore be much less pronounced than if we were using a stronger compound such as Testosterone enanthate. Oily skin, acne, body/facial hair growth and hair loss are all uncommon with nandrolone esters, making them very well tolerated. These preparations are also considered safe for women (at low doses), as virilization symptoms are not a common occurrence. It is important to note however, that there is always the possibility of developing virilization symptoms with this steroid (as with all anabolic/androgenic steroids). To be safest, the faster acting Durabolin® would make a better choice. This faster acting preparation allows the athlete much greater control over blood hormone levels, and is much easier to withdrawal from if problems become evident.

As an anabolic, Dynabolon would be quite similar in effect to Deca-Durabolin®. Again, this drug may display a slightly slower rate of release, with a peak blood concentration being reached slightly later. This may technically equate to a more delayed effect, however this should not be discernible to the user. The most common dosage is 3-4 ampules (241.5 to 322mg) per week, a level that should elicit a very acceptable gain of new muscle mass. Since 4ml is a large injection to administer at one time, this can be further divided into two biweekly injections to avoid discomfort. A higher dosage could be used to elicit a more pronounced anabolic response, however injection volume and frequency will likely become uncomfortably above 6-8 ml weekly.

Nandrolone injectables such as Dynabolon are most commonly incorporated into bulking cycles, although many find that they fit very comfortably in cutting stacks as well. Of course drug testing will limit its use in many such cases however, leaving only the oral nandrolone precursors norandrostenedione and norandrostenediol open to use. Dynabolon can be used alone for a quality mass gain, or in combination with a number of stronger androgens for a heavier gain. Together with testosterone or Anadrol 50®, the growth achieved can be quite formidable. This drug could obviously replace Deca-Durabolin® in the classic Deca/Dbol stack so loved by many. Going back to cutting, we find combining Dynabol with non-aromatizing compounds such as Winstrol® or Anavar helps to dramatically increase the look of hardness and definition. A stronger nonaromatizing androgen such as Halotestin®, Proviron® or trenbolone would provide even more dramatic effect, however related side effects may also become much more pronounced.
