As far as i know Worldwide is a UG. Haven't heard anything bad about them though. I also heard Omnas are really smooth and clean. Looks like you bros helped me make up my mind. The Omnas are 250 mg/ml. I want to start out on a low dose and see how things go. I know its better to inject atleast twice a week to keep blood levels even but if i only wanna do 250 a week is it still ok to just inject once a week?
