from this site....http://siteinjections.com/
i got this info:
*What size needle do I need?
The smaller the gauge the larger the needle.
22 or 23 Gauge, 1.5 Inch is ideal for injections into the glutes.
25 Gauge, 1.0 inch is ideal for injections into the quads and can be used for all spot injections.
25 Gauge, 5/8 inch is often used for tricep/bicep/delts
i went to 3 diff. local drug store and all i find are Insulin syringes....29,30 & 31
(these are readily available off the shelf)...are the sizes 22 & 25 available elsewhere in the store..do i need to ask for them?? what do i say they are for ?
