question from a user

A diabetic friend recently showed me their little auto-clicker injector things for insulin and Ozempic. Their needles are only 1/4" long. Why does the TRT community use 1/2" needles for subq injections if 1/4" is (apparently) long enough?

AlphaMD's Answer

Availability, cost, volume, & different users.

For some of our pharmacies we send 31g 3/8th'' needles out for subq TRT because the next kit size available from that pharmacy/state combination costs $20 more. For other pharmacies their 29g 0.5'' needle/syringes cost less than the 0.25'' long needles.

In Semaglutide it is common to do volumes like 0.05ml to start, up to 0.2ml based on concentration. Smaller needles are fine for that. If you start injecting larger volumes like 0.5mL (TRT) you may want it further from the surface. You can also choose the depth with a longer needle based on your personal needs, but can't make a choice if the needle is too short for you.
