Reply To: Mk667 plus HGH

I’m on mk677 at 25 and I would consider it equivalent to 3-4 iu’s of growth. There has been some long term studies 2years with any real negatives but I have seen blood work that at least the mk677 spikes to levels often seen at over 4 iu and over time levels back out to about 3.

I would cycle the mk677 say 6 on 3/6 off and repeat personally
