Deca-Durabolin ("Deca") is actually the brand name for Organon's version of the compound Nandrolone Decanoate. This 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 that is unique about Deca above nearly all steroids is the mystique it has had for the last quarter of a century. Deca is included in many cycles at doses ranging from 100 rngs/week to 2,000 mgs per week.

Deca also has a very long active life. We can see that a 100mg shot (represented by the circles) produced relatively active and stable plasma nandrolone levels almost until day 10, hence, once a week shots are all that's necessary for stable levels of nandrolone decanoate (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). You'll 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). 

Deca 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. Deca is a progestin (as are all nandrolones), and it happens to stimulate the progesterone receptor 20% as well as progesterone itself. This opens the door for many possible unwanted side effects (water retention, acne, etc...). Aways use testosterone with your Deca! It is suggested 200mgs minimum to avoid impotence and sexual dysfunction. For an anabolic effect from that of Testosterone, we recommend at least double that, with an equal amount of Deca (minimum). Anti-progesteronic drug is also recommended taking an with Deca.

Deca is recommended for a bulking cycle with a dosage of up to 600mgs/week for an extended duration (12-16 weeks), or up to 400mgs/week in a cutting cycle (again, for 12-16 weeks), as long as something to combat water retention was present. Whatever purpose you decide to use Deca for, you still need to include Testosterone in your cycle and have some anti-progesteronic drugs on hand (see paragraph above), just in case.

I will speculate that testosterone in a deca-inclusive cycle must run for at least 2 additional weeks upon cessation of Deca. Baseline testosterone levels take roughly a month to return. Hence, a nice long estered testosterone should run for an additional 2 weeks. I'd also suggest that a particularly aggressive PCT be run after your cycle; nolvadex, HCG, and perhaps clomid should all be utilized in an effort to restore your natural hormone levels as quickly and efficiently as possible.
