Yeah idk what's up but there is definitely a 1 mL barrel shortage around here. Especially for Luer Lock. There's some fuckers on amazon trying to sell a box of 100 for like $45. I am not a fan of luer slip tips.
Anyway, I just came to second using a 27g 1/2" needle. I use that for EVERYTHING, I have never even stuck a 25g needle into my body before, there is just no need to do it. 1/2" gets plenty deep into my muscles (I am quite lean though) and 27g is just easy as hell do deal with. Usually I draw with a 25g then swap it for a 27 and pin with that. If I am only pinning less than .5 mL of fluid I will even just draw and pin with a 29g 1/2" slin pin. Works great, but is much slower.
