Growth Hormone Peptides
Growth hormone secretagogues and related peptides studied for GH optimization.
About Growth Hormone Peptides
Growth hormone secretagogues (GHS) are peptides that stimulate the body's natural production and release of growth hormone. Unlike synthetic HGH, these compounds work with your body's own hormonal systems. Popular GHS peptides include Ipamorelin, CJC-1295, GHRP-2, and GHRP-6. MK-677 (Ibutamoren), while technically not a peptide, is often grouped with GHS due to its similar mechanism. These compounds are researched for their potential effects on muscle growth, recovery, sleep quality, and body composition.
All Growth Hormone Peptides (9)
Ipamorelin
Clinical TrialsAlso: IPAM, NNC 26-0161
A selective growth hormone secretagogue that stimulates GH release without significantly affecting cortisol or prolactin. Considered one of the safest GHRPs.
CJC-1295
Clinical TrialsAlso: CJC-1295 DAC, CJC-1295 no DAC
A synthetic analog of growth hormone-releasing hormone (GHRH) that stimulates GH release from the pituitary. Often combined with a GHRP like Ipamorelin for synergistic effects.
Tesamorelin
FDA ApprovedAlso: Egrifta, TH9507
An FDA-approved GHRH analog used to reduce excess abdominal fat in HIV-infected patients with lipodystrophy. One of the few peptides with FDA approval.
GHRP-6
Clinical TrialsAlso: Growth Hormone Releasing Peptide 6, SKF-110679
One of the first synthetic GH secretagogues developed. Strongly stimulates GH release and significantly increases appetite through ghrelin receptor activation.
GHRP-2
Clinical TrialsAlso: Growth Hormone Releasing Peptide 2, Pralmorelin
A synthetic hexapeptide that potently stimulates GH release. More potent than GHRP-6 with less appetite stimulation, but still elevates cortisol and prolactin.
Sermorelin
PreclinicalAlso: Geref, GRF 1-29
A truncated analog of natural GHRH containing the first 29 amino acids. Previously FDA-approved for pediatric GH deficiency, now used off-label for adult hormone optimization.
MK-677
Clinical TrialsAlso: Ibutamoren, Nutrobal
An orally active growth hormone secretagogue that mimics ghrelin. Not a peptide technically, but frequently discussed alongside GH peptides due to similar effects.
Hexarelin
Clinical TrialsAlso: Examorelin, HEX
A synthetic hexapeptide GH secretagogue with the strongest GH-releasing effect among GHRPs. Also has notable cardioprotective properties independent of GH release.
CJC-1295 DAC
Clinical TrialsAlso: Modified GRF 1-29 DAC, Drug Affinity Complex CJC
A long-acting GHRH analog with Drug Affinity Complex for extended half-life. Provides sustained GH elevation for days with single injection.
Frequently Asked Questions About Growth Hormone Peptides
What are growth hormone secretagogues?
Growth hormone secretagogues are compounds that stimulate the pituitary gland to produce and release growth hormone naturally. They work by mimicking ghrelin or growth hormone releasing hormone (GHRH), triggering the body's own GH production.
What is the difference between GH peptides and HGH?
GH peptides stimulate your body to produce its own growth hormone, while HGH (human growth hormone) is synthetic growth hormone. GH peptides maintain more natural pulsatile release patterns and may have fewer side effects than exogenous HGH.
Which GH peptide is best for beginners?
Ipamorelin is often considered ideal for beginners due to its selective action and minimal side effects. It stimulates GH release without significantly affecting cortisol or prolactin levels, unlike other GHRPs.
