Stacking Sermorelin, Ipamorelin and HGH

[HEKx]

As the title says, I am looking into stacking Sermorelin Profound 1 ml bed time, Ipamorelin 100 or 200 mcg x 3 daily and HGH (Norditropin) 1 iu first thing in the morning.

Please note that I already started Sermorelin since one week.

Is this stack possible? Any interactions/contradictions?

And if it is possible, what is your recommendation for dose/timing?

Please advise.
