I think if you are after increased GH primarily, than you'd be wasting Origin if also taking MK. I look at that aspect of it as being for people that don't want to swallow an experimental drug for increased GH. If you are after the other benefits - then why not?. This would probably be directed mainly at people on a Cut - who would want to have an increased appetite while trying to stick to 2100kcals?, LOL. I do not think it would be additive with MK. And if you are ravenously hungry during a Cut - that's Ghrelin doing it's thing

You also aren't going to put on any LBM during a Cut. At maintenance or bulking - go for it, take them both, you have the kcals in your favor.
