Changing brands mid-cycle

I am just getting started on a Sustanon/ EQ cycle. I dont think I have enough to get through 12 weeks, though. I also am not sure I can get my hands on the same brand gear. Is it acceptable to change brands in the middle of the cycle as long as dosages stay the same?

Thats ok but remember: alot of times the true mg to ml ratio from brand to brand changes.
