You asking if I have a vial ot test Prop and a separate vial of NPp...can you draw up like a 2 ml shot with both in it....we'll, of courseMight not be the place to ask but since I have been reading this thread about since it started and read some pretty good post about anything and everything LOL. I have always tried to take a safety aspect of everything. But how di you mix compounds to only have 1 injection ? Primo and Test C will be my cycle. I have never done 2 compounds at once in injectable. Do you draw them both in to one syringe and change needles ? Just dont want to take 2 shots if not needed.
