For Gh stimulation I like the following protocol: 9 mg melatonin, 1 hr later 100 mcg ea. of ipamorelin and mod grf, 15 min later 1 iu GH. Taking the melatonin doubles the results of the mod grf and ipamorelin and the 1 iu of gh taken 15 min later is recognized as another "pulse" when used this way. What you get is a super pulse of GH release. I only do this at night before bed.
In the above study note that GHRH is basically the same as GRF- We have had subsequent generations of the drug and its referred to name has changed but it is basically the same thing.
IGF-1 lr3 seems to me to be similar in results as fast-acting insulin. Gh itself (in large enough doses) puts more size on me than gh peptides. But, used together they are a great combo.
