27 articlesIpamorelin: A Selective Growth Hormone Secretagogue for Laboratory Research
Ipamorelin is a selective growth hormone secretagogue and ghrelin receptor agonist, currently under investigation in laboratory research for its potential role in growth hormone release and metabolic regulation without the side effects associated with non-selective secretagogues.
Tesamorelin: A Stabilized GHRH Analogue in Growth Hormone and Metabolic Research
Tesamorelin is a synthetic analogue of growth hormone-releasing hormone (GHRH) stabilized by the addition of a trans-3-hexenoic acid group. Research has focused on its ability to stimulate endogenous growth hormone secretion and reduce visceral adipose tissue, particularly in the context of HIV-associated lipodystrophy.
CJC-1295: A Long-Acting GHRH Analogue for Growth Hormone Axis Research
CJC-1295 is a synthetic GHRH analogue modified with a Drug Affinity Complex (DAC) that enables covalent albumin binding, dramatically extending its half-life to 6-8 days. This extended activity profile makes it a valuable tool for research into sustained growth hormone axis stimulation.
Sermorelin: The GHRH(1-29) Fragment in Growth Hormone Secretagogue Research
Sermorelin is a synthetic 29-amino acid peptide corresponding to the biologically active N-terminal fragment of endogenous growth hormone-releasing hormone (GHRH). It stimulates pituitary GH secretion through the same receptor as native GHRH and has been studied extensively as a diagnostic tool and research compound for GH axis investigation.
GHRP-6: A Ghrelin Mimetic and Growth Hormone Secretagogue in Preclinical Research
GHRP-6 (Growth Hormone Releasing Peptide-6) is a synthetic hexapeptide that acts as a ghrelin mimetic, stimulating GH secretion through the GHS-R1a receptor. It is one of the original synthetic growth hormone secretagogues and has been widely used in research to investigate the ghrelin axis and its role in GH regulation, appetite, and metabolic function.
GHRP-2: A Potent Synthetic Growth Hormone Secretagogue in GHS-R1a Research
GHRP-2 is a synthetic hexapeptide growth hormone secretagogue that activates the GHS-R1a receptor with higher potency than GHRP-6. It produces robust, dose-dependent GH release with comparatively less appetite stimulation, making it a widely used research tool for GH axis investigation.
CJC-1295/Ipamorelin: Synergistic GHRH and GHRP Combination in Growth Hormone Research
The combination of CJC-1295 and ipamorelin represents a dual-pathway approach to GH axis stimulation, pairing a long-acting GHRH analogue with a selective GHRP. Research has demonstrated that this combination produces synergistic GH release substantially greater than either peptide alone, making it a widely studied protocol in growth hormone research.
