Evidence-Backed Outcomes Adults using Sermorelin for six months reported improved sleep quality, reduced waist measurements, and higher IGF-1 levels without significant adverse events
In a controlled study cited in the same review, participants who slept 5.5 hours per night lost less fat and more fat-free mass than those who slept 8.5 hours per night. The authors reported that sleep curtailment decreased the proportion of weight lost as fat by 55% and increased the loss of fat-free body mass by 60%. Poor sleep has also been linked to increased hunger and changes in appetite-regulating hormones

What is cagrilintide and how does it differ from semaglutide Cagrilintide: Long-acting amylin analog What cagrilintide is: Synthetic analog of amylin (human hormone) Long-acting formulation (weekly dosing) Developed by Novo Nordisk Currently in Phase 3 clinical trials Not yet FDA approved (as of 2024) Paired with semaglutide as "CagriSema" How amylin works naturally: Co-secreted with insulin from pancreatic beta cells Released after meals Slows gastric emptying (food stays in stomach longer) Reduces glucagon secretion Signals satiety to brain Regulates postprandial glucose Cagrilintide's mechanisms: Mimics natural amylin but lasts much longer Dramatically slows gastric emptying Increases satiety and fullness Reduces food intake Lowers postprandial glucose Works on amylin receptors (different from GLP-1) Primary benefits: Powerful appetite suppression Extended feeling of fullness Reduced meal frequency Lower caloric intake Glucose regulation Complements GLP-1 action Learn about peptides , how peptides work , and what are peptides used for in our foundational guides
