Selank is a synthetic heptapeptide analogue of tuftsin studied in experimental models for its anxiolytic and nootropic properties, with research focusing on its modulation of GABA, serotonin, and BDNF signaling pathways.
Tirzepatide: A Dual GIP/GLP-1 Receptor Agonist in Metabolic and Obesity Research
Tirzepatide is a synthetic dual agonist of the glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors. Preclinical and clinical research has demonstrated significant reductions in body weight and improvements in glycemic control, positioning it as a subject of intense metabolic research.
Retatrutide: Triple Receptor Agonism in Next-Generation Obesity and Metabolic Research
Retatrutide is a novel triple agonist targeting GIP, GLP-1, and glucagon receptors simultaneously. Early-phase clinical research has reported unprecedented weight loss magnitudes, positioning it as one of the most potent anti-obesity compounds currently under investigation.
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.
