What is Nandrolone undecylate
Nandrolone undecylate (Dynabolon) is a very unique nandrolone ester.
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.
Nandrolone undecylate (Dynabolon) 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.
Application and dosage
Nandrolone undecylate is an effective compound that produces quality, long-lasting muscle gains. This is because of the relatively long half-life of the drug (around 8 days). Users report mild side effects, with the biggest side effect being water retention.
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.
