Omadren is made by only one company right now, Jaffa Poland. 2 years ago is was diffent then sustanon, like sustanon it was a blend of 4 different types of testosterone except it had 2 difffernt types which resulted in a pure bloat almost like suspension. Now it is exactly the same as sustanon, but remember sustanon has prop in it, so to keep steady blood levels it must be shot every 3 days.
