I've never mixed 2 aas in one, I've always preloaded for my cycle, now that I'm going to use 2ml of deca and 1ml of test prop, I don't know if I should preload just the deca then just draw up the test when I inject. Or to mix and preload them both for my complete cycle .. there shouldn't be any problems with mixing the 2 for my 8 week cycle is there?
