Says who? I've done this numerous times over the years and have had 0 issues. The syringes are sterile, or, no less sterile than the 5ml vials I filter my peps into.This is a huge nope, for me. Syringes are not meant to hold things long term. If you choose to do this, it ups your chances of at the very least, ISRs and at the worst infections like cellulitis.
Now, having said that, I don't keep pre-filled syringes in my fridge for more than ~10-14 days (and always keep refrigerated).
