Hi ,up here in Canada every few months i get ahold of the 10cc upjohn 100 mg per ml cyp this stuff i dont think is as good a sustanon but if you can get ahold of testex elmu or the korean depovirion ,i think they work better then sustanon ,for some reason they just seem to work better then the bottled cyp ,alot of guys i know who tried the 3 also agree the amps work better
