I have bought insulin syringes for my peptides on Ebay with good luck. havent looked for anything bigger though....

use a google certified vet source.. have a good day

I like to use a 23g cause you can feel it going through skin, muscle and arteries. Aspirate, but you will know where you are. No difficulties, no mistakes.

No source talk bro, edit your post.

Look under sources>accessories, there are dozens of already proven sources there.
