GHRP-2 is a synthetic ghrelin receptor agonist that activates two simultaneous intracellular signalling pathways at GHSR-1a, driving potent growth hormone secretion alongside predictable cortisol and prolactin release.
Read articleTesamorelin stabilises the native GHRH peptide via N-terminal modification, extending its half-life at the GHRH receptor and sustaining second-messenger cascades that drive prolonged growth hormone secretion.
Read articleIpamorelin's pentapeptide structure confers remarkable selectivity for GHSR-1a, releasing growth hormone without the cortisol elevation seen with first-generation GH secretagogues. This article examines the molecular basis for that specificity.
Read articleThe DAC linker on CJC-1295 binds albumin to extend GHRH receptor engagement for nearly a week. Learn how this differs mechanistically from Mod GRF 1-29's rapid, pulsatile signalling.
Read articleMOTS-c, a 16-amino-acid peptide encoded in mitochondrial DNA, activates AMPK and improves insulin sensitivity in mouse models through intracellular folate-cycle signalling. We examine the molecular mechanism.
Read articleSemaglutide's selective activation of the GLP-1 receptor—without agonism at GIP or glucagon receptors—produces its clinically validated weight loss through a cascade of peripheral and central mechanisms that unfold over hours and days.
Read articleDual GIP and GLP-1 receptor agonism produces metabolic outcomes that exceed what either pathway achieves alone. This article explains the molecular basis for synergistic co-activation.
Read articleRetatrutide binds three distinct incretin and metabolic receptors at once, creating synergistic effects that exceed single-agonist approaches. This article explores the molecular pharmacology and intracellular signalling cascades that drive its metabolic action.
