Surprised more people don't use this brand the oil is incredibly thin and has zero pip and the vials are literally better then any other iv gotten , the only thing that could be alil better is the rubber stopper u pin through nothing wrong with it I just prefer a tighter dark rubber then the clear ones really is nothing to complain about though expecially with the quailty of the gear best and closest test reports iv seen of any lab other then maybe Balkan
