Deca Durabolin (“Deca”) is a 19-Nor compound (some would say that it is the 19-nor compound), and as such, it shares basically the same characteristics with all of them. One thing unique to Deca, above nearly all steroids, is the mystique it has had for the last quarter of a century. On a personal level, Ive included Deca in cycles at doses ranging from 100mgs/week to 2,000mgs per week. Suffice to say, I have my fair share of experience with Deca Durabolin. This drug was regarded very highly by Dan Duchaine in his Underground Steroid Handbooks as well as many of his later writings. For many, this was and is the final word on Deca. Lets delve into some of the reasons that Decas mystique may be well deserved.
First of all, Deca Durabolin (and Nandrolone in general) doesnt produce many estrogenic or androgenic side effects. This is because Deca Durabolin has a very low rate of aromatization (conversion to estrogen via the aromatase enzyme), roughly equal to 20% the rate of Testosterone.
Also, Ive read many places that Deca Durabolin stores water in connective tissue, thus alleviating joint pain. I have no idea what “storing water in the joints” means. I have no idea how to really quantify that statement, or where it started. However, in one study of postmenapusal women, Deca impoved collagen synthesis (1), and in another study Deca Durabolin increased bone mineral content. (2)Both of these studies used VERY low doses, which were far too low to promote muscle growth. In my estimation, based on these 2 studies, an athlete attempting to use Deca only for these two effects (increasing bone mineral content and collagen synthesis) should be using 100mgs of Deca Durabolin every week. Thats actually a higher dose than those two studies used successfully. Even at of this dose, in HIV+ patients who have experienced significant wasting, a 100mg/E2W (every 2 weeks) injection of Deca resulted in a “significant increase in weight” (5). Id never recommend that low of a dose for an athlete, but its evidence of Decas strong anabolic properties.
Deca is a very nice anabolic, causing nice (albeit slow) gains in quality muscle. This could be due to its moderately strong binding to the Androgen Receptor, or its many positive non-Androgen-Receptor mediated effects. One such effect is nitrogen retention, which is a major factor in muscle growth and lean mass gains; in one study, with low-doses (65 mg/week) and high-doses of Deca (200 mg/week), both low-doses and high-doses resulted in significant nitrogen retention (33-52 g nitrogen/14 days, representing gains of 0.5 to 0.9 kg lean tissue/week), and body weight increased by 4.9 +/- 1.2 kg, including 3.1 +/- 0.5 kg lean body mass, and treadmill exercise performance (cardiovascular fitness) also improved (7). Need I say that the higher doses in this study produced more gains? BD members who have posted their results with Deca Durabolin confirm this in many posts and threads, with their average reccomendation being to take 400-600mgs/week for muscle gain. I have to agree.
Deca Durabolin,Steroids,Deca Deca Durabolin also has a very long active life. We can see from the chart below that a 100mg shot Deca (represented by the circles) produced relatively active and stable plasma nandrolone levels until day almost 10, hence once a week shots are all thats necessary for stable levels of nandrolond Deca Durabolinnoate (as a side note, the nandrolone phenylpropionate used in this study was active, and only experienced a severe drop off around day 5, shooting NPP every 4th day is the way to go). Youll also note that higher blood plasma levels of Nandrolone are found with Gluteal injections as opposed to Deltoid injections (this is true for all oil-based steroids, I suspect).
In another study of HIV+ men (6) we can see that Deca Durabolin ( 200mgs on week 1, 400 on week 2 and 600mgs for weeks 3-12) caused NO negative side effects in total or LDL cholesterol, triglycerides, or insulin sensitivity and there was a reduction of HDL cholesterol(8-10 points) in both groups. Also, in most studies with HIV+ subjects, Deca Durabolin also improved immune function.
So what do we know so far about this compound? So far, we know thatDeca Durabolin is a very safe drug for long term use, will help with joint problems, could improve immune function, and is highly (!) anabolic, and not very androgenic.
Thats the good news (and theres a lot of it), now for the bad news:
Deca Durabolin is known for producing quality weight gains, but it has to be used for 12 weeks at a minimum, judging from BD members feedback, as well as my own personal experience. This shouldnt cause any problems, since it is a very mild drug in terms of side-effects.
