B12 injection - water or oil based??

I always thought B12 was an oil based inject....?
I just got my first order & I'm pretty sure it's water based....?
Anyone use B12 ? Is it water or oil based ??
Just curious as it didnt really mix properly with my prop - ended up with what looked like a strawberry shake !

b-12 is water based

yup, water based. first draw your oil, then slowly draw your b12. inject the b12 a little slower. just pay a little more attn to the pressure

thanks guys - I'd just been shaking the two together & making a kind of pink emulsion...but I think it was causing some of the prop to crash (still didn't hurt tho).
