I wouldn't use 25 gauge for a suspension Winny such as Jurox. It gets clogged up too much. I would use 23 gauge. Just my preference from past experiences.
HEy I have been trying to find someone who has used the stanazol by RWR.....anyone know how to make sure it is legit...This stuff is so fine...no seperation at all?
I posted this other day , im using 22 1 1/2 for winny, susp. combo, which is Jurox and like enigma said sometimes it can clog with smaller guage. I too think this is big, but oh well dont have to worry bout clogging half way through.
when i'm tired of injecting in the same places w/ huge ass needles, i'll even drop downto a 25g 5/8" pin and shoot it in my pecs/shoulders/lats. have seen great results with this but only in decent-sized muscle areas that have very very little fat to penetrate.
