Very good and sterile. I liked the stuff so much I purchased 20 more. It is an excellent injectable. It will produce excellent size and is high in quality. If it does not come from Organon then it is from a source that counterfeits it.
Chances are that the stuff is real.
The only thing I would be concerned with is how sterile it is. Many of my friends use it and it has been fine so far. It has very side effects and it has long term benefits. Their should only be 10 ampoules in the box. On the ampoules the words Deca Durabolin and the dosage are silk screened directly on the ampoules glass.
