Anabolic DN is an underused product, for one reason or another. Anabolic DN is currently produced by SYD Group who had some very inconsistent lab reports posted on the net, with regards to their product line. It was also produced previously by Jurox, under the name Dynabol. It's also under used, I think, because it's an obscure buy for most people outside of Australia, where those aforementioned companies reside.
Let's have a look at Nandrolone, then we'll discuss the addition of the Cypionate ester in opposition to the much more commonly used Decanoate ester (the ester used with Deca-Durabolin). First of all, Nandrolone doesn't produce many estrogenic or androgenic side effects. This is because it has a very low rate of aromatization (conversion to estrogen via the aromatase enzyme); roughly equal to 20% the rate of Testosterone. Nandrolone is a very nice anabolic, in my estimation (even though I don't use it anymore), and a 100mg/E2W (every 2 weeks) injection of it has been shown to provide a "significant increase in weight" (3). I'd never recommend that low a dose for an athlete, but it's evidence of Deca's strong anabolic properties. All of the Nandrolones are very nice anabolics, causing high-quality (albeit slow) gains in muscle. This could be due to Anabolic DN's moderately strong binding to the Androgen Receptor (stronger than testosterone, actually), or possibly its many positive non-Androgen-Receptor mediated effects. One such non-receptor mediated effect is nitrogen retention, which is a major factor in muscle growth. Even with low-doses of Nandrolone (65 mg/week), Nandrolone produces significant nitrogen retention (5).
Nandrolone is also well known to improve collagen synthesis (1), and increases bone mineral content (2). For these purposes, studies on Nandrolone use very low doses and were generally far too low to promote muscle growth.
In another study of HIV+ men (4) we can see that Nandrolone (200mgs on week 1, 400 on week 2 and 600mgs for weeks 3-12) actually caused NO negative side effects in total or LDL cholesterol, triglycerides, or insulin sensitivity. In addition, there was a reduction of HDL cholesterol (8-10 points) in both groups. Also, in these studies with HIV+ subjects, Anabolic DN, Nandrolone improved immune function (5).
Judging from Steroid.com members' feedback, as well as my own personal experience, long-estered Nandrolones are known for producing quality weight gains, but have to be used for 12 weeks at a minimum. This shouldn't cause any problems, since they are very mild drugs in terms of side-effects, and I don't think they would cause many adverse effects over this period of time. Nandrolone Cypionate has a very long active life, of roughly 8 days or so, slightly less than the far more common Nandrolone Decanoate (Deca). This would mean we want to shoot Anabolic DN 1-2 times a week, along with our other compounds because we'd probably be running Testosterone Cypionate with it.
Many members of Steroid.com also complain of water-retention with this the use of longer-estered Nandrolones, and again, I'm inclined to agree. Letrozole seems to be a preferred choice to combat this and it's been my favorite for this use, on cycles of 12-16 weeks. This water retention would seem to make something like Anabolic DN more suitable for bulking rather than cutting, although it can be successfully used for either with a proper diet and use of ancillary compounds.
So where are we? How would I use Anabolic DN personally? Well, I'd be comfortable recommending Anabolic DN for either a bulking or cutting cycle, and I think its real utility would be that you can use it along with Testosterone Cypionate and inject them on the same day because they'd have the same active life.
