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.

So what do we know so far about this compound? So far, we know that 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. That’s the good news (and there’s a lot of it).

First of all, Deca (and Nandrolone in general) doesn’t produce many estrogenic or androgenic side effects. This is because Deca has a very low rate of aromitization (conversion to estrogen via the aromatase enzyme). Its rate is roughly equal to 20% the rate of Testosterone.

Nandrolone Decanoate (Deca) is widely considered to be the most
commonly used injectable anabolic steroid used for performance
enhancement. It also has the reputation for being one of the
most frequently detected banned substances (metabolites can
be detected for periods in excess of one year). Because of its
popularity Deca has been widely counterfeited. Due to its relatively
low androgenic properties it is also commonly thought to aromatise
only at high doses. Deca is commonly used for ‘bulking-up’ and has
a reputation for promoting size and strength.

Side effects :

Reports of side effects include hypertension, acne, sexual and
reproductive problems. The occurrence of side effects appear to
be more common in females and are influenced strongly by the
dosage used.

Nandrolone Decanoate Dosage:

I’d be comfortable recomending Deca 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.
