[USER=38859]@Rain27[/USER] , Testoviron 250mg and Nebido are intended to be administered with a single shot, therefore the manufacturer doesn't add Benzyl Alcohol which is needed to prevent bacteria growth in a situation where you make multiple shots from the same batch over a period of time. BA is added to multi-dose Testoviron vials sold in the US.
I use Testoviron 250mg for five bi-weekly shots. I measure 0.01ml Benzyl alcohol (close enough to 0.9%) via an insulin syringe (using the 1IU mark) and add it to the Testoviron. I buy the BA for 6$ here:
