My apologies if this has been covered before (I wasn't able to find anything searching in the old threads covering it). For combining two injections in one go, like say deca and test e, I find it mildly difficult to draw up the second substance in the same barrel measured as accurately as the first, and I dislike not being able to equalize pressure (although I don't dislike it enough to split it into two pinnings, because who the hell wants to stick themselves even more). Given the test and deca are from the same lab using the same carrier, is it reasonable to purchase new sterile vials and attempt to premix them both together at the ratios I want to run my cycle at, so I can heat and draw from one vial when the time comes to pin? Is there any consequences to this, like something may fall out while sitting like that a few weeks, or maybe it unacceptably raises the risk of contamination? Appreciate anybody's thoughts or experience with this. Thanks!
