GHK-Cu is a copper-complexed tripeptide that circulates in human plasma at concentrations that decline with age. The copper ion is essential to its bioactivity, enabling stable binding to collagen and growth factor receptors.
Read articleTB-500 works by sequestering actin monomers in a polymerisation-resistant state, creating a reserve pool that fibroblasts and other cells draw upon during migration and tissue remodelling. This mechanism underpins wound healing and cardiac repair in animal studies.
Read articleBPC-157 potentiates growth factor receptor signalling in tissue repair through cross-pathway amplification rather than direct binding. This mechanism underlies its effects in published rat models.
Read articleTesamorelin is a stabilised full-length GHRH analogue engineered to resist rapid receptor desensitisation. This article examines how its N-terminal modification sustains pulsatile growth hormone secretion and the molecular basis for its 26-week efficacy profile.
Read articleCJC-1295 DAC binds albumin to sustain GRF receptor signalling for up to a week, fundamentally altering the temporal dynamics of somatotroph stimulation compared to the minute-scale pulses of natural GHRH and non-DAC Mod GRF variants.
Read articleIpamorelin's five-residue structure delivers growth hormone pulses without the unwanted ACTH and cortisol rise seen with earlier GHRPs. Discover the receptor selectivity and signal transduction basis for this cortisol-sparing property.
Read articleMOTS-c is a 16-amino-acid mitochondrial peptide that activates AMPK and improves insulin handling in mice. We map the molecular cascade from receptor engagement to metabolic adaptation.
Read articleSemaglutide is a GLP-1 receptor agonist that activates a multi-level signalling cascade from the pancreas through the gut to the brain, driving weight loss through distinct mechanisms that do not overlap.
Read articleTirzepatide binds both GIP and GLP-1 receptors as a dual agonist, producing a distinct metabolic profile without glucagon pathway engagement. This article examines the molecular basis of its selectivity.
