Can you inject Test-E and B-12 together

[bfq]

Kinda random, but i was wondering if you could put injectible vitamine b12 in the same syringe as Test-E and get both out of the same injection.

You can but have read that the injecting of an oil based substance and a water based substance dramatically increases your risk of infection.
However, that being said when I was a dumb 20yo I used to inject EQ and B12...

or abcess from what I have read. oil and water do not mix... test IM with 23 or whatever gauge and b12 SQ with slin pin.
