I'll say it again : you absolutely do not need a filter with cere. I've done more than 45 injections of this thing using a 18G needle for extraction and a 25G for injection at various sites (deltoids, quadriceps, glutes) without ever a single problem. The professionals that use it in austria do not filter it either. Don't know why some of you you guys insist on that filter thing being a good idea with cere. It's not, only a totally useless waste of time and money (yeah do the math it does add up).
Also, you can aspire FAST from the amp with the 18G, you will get some bubbles which will be easily flicked away, leaving only "micro-bubbles" that DO NOT MATTER AT ALL. Please hire a licensed nurse for one injection and see if she bothers with all these paranoid and time wasting "precautions".
Again, IM injections of CERE are NOT A BIG DEAL, just snap ampoule, draw cere with 18G fast, flick serynge, switch to 25G needle, make sure you have a "big nerve"-free site, sanitize your skin, pin swiftly (no need to take ages to dig the needle in), aspire to check if hit a vein, inject at moderate speed and that's it, it should not take you more than 5-8 minutes total!!!
