russian sustunon 250 does not exist to my knowledge, i am currently in ukraine, here it is labled as omnadren 250, yes i know there is a differnce, but according to my sources here, whom i trust completely, they have modified the ingridients to that of what in the states is known as sustunon, i have used the omnadren myself and know it is legit. try and post some pics. i understand sustunon consists of four differnet testosterones as did omnadren, however, the omnadren here is analogous to the sustunon i have purchased in the states.
