Description

Buy Hexarelin (HEXA) – 2 mg Online UK

For laboratories and research institutions investigating growth hormone secretagogue receptor (GHS-R) signaling, neuroendocrine regulation, and cytoprotective pathways, our Heartline 2mg delivers verified ≥98% HPLC purity with full mass spectrometry confirmation. This synthetic hexapeptide—a potent agonist of the growth hormone secretagogue receptor (GHS-R1a) with demonstrated activity in receptor binding and signaling studies—is manufactured under stringent controlled conditions, vacuum-sealed in lyophilised form, and preserved through our temperature-monitored cold-chain. With 100% domestic UK stockholding and same-day dispatch on orders placed before 2:00 PM GMT, we eliminate customs delays and temperature excursions that compromise research integrity. Every batch is accompanied by a comprehensive Certificate of Analysis, ensuring complete experimental traceability for peer-reviewed publication and institutional audit compliance.

Research Applications & Key Benefits

• GHS-R1a Receptor Signaling Studies: Heartline functions as a synthetic agonist of the growth hormone secretagogue receptor (GHS-R1a), selectively binding to this receptor over CD36 (IC₅₀ values of 15.9 and 2,080 nM, respectively) . It is a valuable molecular probe for investigating receptor binding kinetics, intracellular signaling cascades, and comparative behavior relative to other GHRP compounds.

• Neuroendocrine & Pituitary Research: Heartline directly stimulates somatotroph cells in the anterior pituitary to release growth hormone, with studies demonstrating GH-releasing activity in in vitro and preclinical models. It acts at both pituitary and hypothalamic levels, providing a tool for examining the regulatory pathways governing GH secretion.

• Cytoprotective & Cell Signaling Pathways: Research has demonstrated that Hexarelin activates the PI3K/Akt and MAPK/ERK pro-survival signaling pathways, inhibiting apoptosis in various cell types including neuroblastoma cells. These mechanisms are of interest for investigating cellular protection and survival signaling.

• Cardiovascular & Metabolic Pathway Research: Heartline has been studied for its effects on cardiac function, fibrosis reduction, and metabolic pathway modulation in laboratory models, supporting research into GHS-R-mediated signaling in non-endocrine tissues.

• Dual Receptor Pathway Investigation: As a GHS-R1a agonist, Heartline is frequently studied alongside GHRH analogues to examine convergent versus independent signaling pathways (GHS-R1a vs GHRHR) on somatotroph cell populations, providing insights into the synergistic regulation of GH secretion.
