drawing 2 steroids in the same syringe?

[The Observer]

Can't you just push air into both vials then draw from vial 1 then vial 2? Afterwards change the needle and inject?

I don’t personally need to inject air into the compound before I withdraw it but I guess it makes it easier but yes definitely change out the needle, personally I’ll draw the compounds with a larger needle and inject with like a 23 or even 25 if it’s not too thick
