I posted about this on another forum and thought I should share it here as well. I stumbled on this by accident. I always take melatonin before bed and one night I took my melatonin an hour before my ipamorelin (similar to ghrp-6) and cjc (mod grf 1-29) and noticed what seemed to be a greater feeling of GH release. Euphoria, sleepiness etc. that was more profound than with just one substance or the other. When I added in an iu of GH 15 min later it was even greater. Now I've stopped my other peptide shots and just do this one protocol per night. The side effects (stiff fingers/hands) got to be too great with multiple shots per day.
I knew about 1-2 iu of GH promoting a much bigger "pulse" when combined with peptides. But, I wondered what part melatonin played in it as I had always heard that it created a slight GH release on its own.
Here's what I found-

Melatonin stimulates growth hormone secretion through pathways other than the growth hormone-releasing hormone.

Abstract
OBJECTIVE: There is evidence that melatonin plays a role in the regulation of GH secretion. The aim of this study was to investigate the neuroendocrine mechanisms by which melatonin modulates GH secretion. Thus we assessed the effect of oral melatonin on the GH responses to GHRH administration and compared the effects of melatonin with those of pyridostigmine, a cholinergic agonist drug which is likely to suppress hypothalamic somatostatin release.
DESIGN: The study consisted of four protocols carried out during the afternoon hours. Study 1: oral melatonin (10 mg) or placebo were administered 60 minutes prior to GHRH (100 micrograms i.v. bolus). Study 2: GHRH (100 micrograms i.v. bolus) or placebo were administered at 0 minutes; oral melatonin or placebo were given at 60 minutes and were followed by a second GHRH stimulus (100 micrograms i.v. bolus) at 120 minutes. Study 3: placebo; oral melatonin (10 mg); oral pyridostigmine (120 mg); melatonin (10 mg) plus pyridostigmine (120 mg) were administered on separate occasions. Study 4: placebo; oral melatonin (10 mg); oral pyridostigmine (120 mg); melatonin (10 mg) plus pyridostigmine (120 mg) were administered on separate occasions 60 minutes prior to a submaximal dose (3 micrograms i.v. bolus) of GHRH.
SUBJECTS: Four groups of eight normal male subjects, ages 22-35 years, were randomly assigned to each protocol.
MEASUREMENTS: Growth hormone was measured by RIA at 15-minute intervals.
RESULTS: Oral melatonin administration had a weak stimulatory effect on GH basal levels. Prior melatonin administration approximately doubled the GH release induced by supramaximal (100 micrograms) or submaximal (3 micrograms) doses of GHRH. Melatonin administration restored the GH response to a second GHRH challenge, given 120 minutes after a first GHRH i.v. bolus. The GH releasing effects of pyridostigmine, either alone or followed by GHRH, were greater than those of melatonin. However, the simultaneous administration of melatonin and pyridostigmine was not followed by any further enhancement of GH release, either in the absence or in the presence of exogenous GHRH.
CONCLUSIONS: Our data indicate that oral administration of melatonin to normal human males increases basal GH release and GH responsiveness to GHRH through the same pathways as pyridostigmine. Therefore it is likely that melatonin plays this facilitatory role at the hypothalamic level by inhibiting endogenous somatostatin release, although with a lower potency than pyridostigmine. The physiological role of melatonin in GH neuroregulation remains to be established.

I put the pertinent results in bold. I believe that ghrh is essentially what grf is, just a different name. And, I think that it has the same doubling effect on other growth hormone releasing peptides more than likely.
Try it, and see what I mean. You'll get an amazing night's sleep and feel like you just took 10 iu of GH. Plus, this is a very cheap way to get a lot out of a very little. The combo costs about $2.10 for everything per use vs. $15 or so for 10 iu of GH. It's a huge savings and your body recognizes it as a natural "pulse".
