I normally use a 25 G one inch needle everywhere, glutes, delts, thighs, but I was considering for smaller (1 cc) days using a half inch 29 G insulin needle.


I guess it would be too dull after inserting into the stopper, but I used it that way for HCG (in the belly fat).

Thoughts on using a 1/2 inch 29 G in delt?
