I just got some sust. 250 prepackaged in a syringe with a needle size of 21g or .90mm 1.5"lg. Is 21g to big for injecting? (The needle itself is in it's own package) Should i go for a smaller needle size? I've heard 23g is the size you want for injecting, if so then why would they(Organon) package it with this needle size
