Does cardio kill your muscle gains?

Should I do cardio and weights on different days?

So weights 3 days a week and cardio 4 days a week? Lots of research and science has proven that you technically don't lose it but you also don't gain it by doing cardio less than 6 hours. So it says either wait 6 hours plus or preferably 24 hours

What is your experience?
