Dynabolon (nandrolone undecanoate) is a very unique nandrolone ester. It is produced only in Italy and France and has a reputation of being more potent than the other nandrolones. Each ampoule contains 80.5mg of nandrolone undecanoate, in 1ml. It has a shorter life in the body than Deca Durabolin.
Athlete’s generally opt to inject this product twice weekly to keep blood levels more even. There are counterfeit version of this, but as of yet are only loose ampoules. A boxed Dynabolon with insert and sealed ampoule tray should be legitimate. This product does make it to the U.S. black market, but not very often.
Nandrolone undecanoate is the chemical name of active ingredient in Dynabolon. Dynabolon was originally a registered trademark of Laboratoire Théramexin Monaco and/or other countries prior to cancellation.
