People still use it... There are just so many different choices now a days... Bodybuilders haven't always had so many options open to them. Deca became really popular in the 80's and 90's because it was readily available everywhere... At that time, Deca, Testosterone, Dbol, Anadrol, Winny were easily available... Parabolan, Anavar, Primobolan, etc were commonly faked and you just didn't see them around a lot. And way way more expensive then they are today.
