Weird Way of Filling Up Syringe


So, i’ve switched to insulin syringes today but there’s one problem with filling them up ‘normally’. My testosterone comes in ampoules instead of vials so it’s very difficult to load syringes the normal way. What i do is - i am using another syringe, loading it up, then remove the plunger from insulin syringe and just “inject” testosterone there, then I just slowly insert the plunger and wait until test drops down at the end of syringe. Is that ok? :smiley:

Its called back filling this syringe. Lots of people do it but I’m not a fan as you are breaking sterility protocol with the syringe IMO. But alas… it is done often indeed.
