propper viromone is what you want, try and stay away from the multi shot shite thats floating around at the mo, always go for the glass vials in the nice packaging if youve got acsess to it,,,, im finding it almost impossible to get propper gear anymore, all they want to sell is underground multi shot gear... some of it is ok, but alot of it is complete rubish, if your lucky its weak test cyp at best with different labels on
