I heard Desmo Testex Prolongatum stopped adding preservative at a certain batch numbers. Does anyone know at which batch numbers they stopt adding preservatives. I ask this because I take the 250mg/2ml solution from several ampules and put the contents in to a 10ml vial and get through the vial in a few months but can’t do that if there is no longer preservative in the Testex. I have some unopened ampules from some time ago and some I got this week all with different batch numbers but I don’t know which batch numbers if any have the preservative in. I got them in Spain.
