25ga for test and other oil? i always thought that was too small
(although i have never tried it) I normally use 23ga, but you think i can shoot Test Ethanate with 25ga? if so ill give it a try.
as for length, i use 1" for delts and quads, 1.5" for glutes. let me know.
One more question, when i order needles, it seems like i have to order about 20 at once. How do i get just one 18ga to draw oil based?
Thanks
