Can I do this?

after withdrawing my B12 can I use the Same Needle to withdraw the Test?

I dont see why not, just make sure non gets into the test bottle.

withdraw is fine, just dont shoot it and then try to use the same one. i would withdraw the test first, then the b12.

how much b12 are you using to cut prop with?

Just change needles for injecting , you'll be fine.

I would definately use a different needle for every injection, you don't want to get an infection because of a dirty needle

he's using the same needle to withdraw, not to inject.

I use the same needle to withdraw both B-complex and test and EQ too :) It'll work fine but go with what the others have told you and be sure to change the needle b4 injecting.

does using the same needle for diff substances not contaminate the test in this case?

just curious

Yah I always use a clean new needle to inject, was just curious about the withdrawing the B12 then contaminating the Test but all as been fine so far, im using 1/2 CC, 500mcg of B12 ED with 3/4 75mg/ED Test.
