A companion mechanistic paper, Chang et al., Molecules 2014, found that the peptide up-regulated growth-hormone-receptor expression in tendon fibroblasts at both mRNA and protein levels, potentially sensitising these cells to growth hormone during repair

Patients going out of their way to gain access even if that means going to someone other than their primary care physician

Biological analyses were performed on stool samples (16S rRNA sequencing) and blood serum (ELISA for oxytocin, inflammatory and neuroinjury markers), while behavioral outcomes were assessed using SRS, ABC and CGI

Known as glucagon-like peptide-1 receptor agonists (GLP-1RAs), these drugs mimic the natural hormone GLP-1, which binds to and activates GLP-1 receptors in the brain and gastrointestinal tract, regulating blood sugar levels and reducing food intake

Timeline of Regulatory Milestones 2005: Exenatide (Byetta): First GLP-1 agonist approved, twice-daily injections 2010: Liraglutide (Victoza): Longer-lasting, once-daily injection 2014: Dulaglutide (Trulicity): Once-weekly injection arrives 2017: Semaglutide (Ozempic): First once-weekly injection for diabetes with powerful weight-loss effects 2019: Oral semaglutide (Rybelsus): First GLP-1 pill makes it past the stomachs defenses 2021: High-dose semaglutide (Wegovy): FDA approval for obesity treatment 2022: Tirzepatide (Mounjaro): First dual GLP-1/GIP agonist for diabetes 2023: Tirzepatide (Zepbound): Expanded approval for obesity 20232024 : Widespread shortages: Skyrocketing demand for GLP-1s leads to limited availability The shortage that began in late-2023, driven by soaring off-label demand and supply-chain bottlenecks left millions of patients unable to fill even maintenance scripts
