@Cocoon992 you can do IM with 25guage just takes time, I've done 25g 1/3 ML into the shoulder no problem but if the gear is too thick you can use 23G 1inch into the shoulder or into the bicep, but you need to make sure you dont try to inject too much, 1/4th ml so 0.25ml injection site via IMIs it then possible to inject intramuscularly with a 25 gauge? My girlfriend says she has never heard that in her entire career and only uses 21 gauge intramuscularly?
