Split Dose

Can anyone advise where to get syringes/needles?

I plan on doing 6.25mg instead of moving straight up to 7.5mg. I’m currently on 5mg but I can really feel the hunger kicking back in, this week in particular. I’m trying to hold out until I use up the 5mg pens I have, which is about 6 doses/weeks, but the way I’m feeling this week that might be too far away.

I’ve looked at the click calculator and it says to do 4 doses with the pen and 2 with syringe. I did buy some from Amazon but I read since that they shouldn’t be used.
