Over 17,000 trial participants have demonstrated significant efficacy through appetite suppression and glycemic control. The 7-day half-life enables convenient weekly dosing. ### Mechanism of Action Mimics native GLP-1, binding to receptors to stimulate glucose-dependent insulin secretion, suppress glucagon, slow gastric emptying, and reduce appetite via hypothalamic pathways. ### Key Benefits - 15-20% average body weight reduction - Established cardiovascular protection - Convenient once-weekly dosing options - Comprehensive safety data from extensive trials - Flexible injectable and oral formulations ### Quick Stats Typical Dose 0.25mg starting, titrate to 1-2.4mg weekly Frequency Once weekly (same day each week) Cycle Duration Ongoing therapy as prescribed Storage Pen: 2-8°C before first use, room temp up to 56 days after. Compounded: 2-8°C ## Molecular Information Molecular Weight 4,113.64 Da Length 31 amino acids Type GLP-1 receptor agonist Half-Life ~7 days (168 hours) ### Amino Acid Sequence One-letter: `HUEGTFTSDVSSYLEGQAAKEFIAWLVRGRG` His 1 Histidine Position 1 Aib 2 Aminoisobutyric Acid Position 2 Glu 3 Glutamic Acid Position 3 Gly 4 Glycine Position 4 Thr 5 Threonine Position 5 Phe 6 Phenylalanine Position 6 Thr 7 Threonine Position 7 Ser 8 Serine Position 8 Asp 9 Aspartic Acid Position 9 Val 10 Valine Position 10 Ser 11 Serine Position 11 Ser 12 Serine Position 12 Tyr 13 Tyrosine Position 13 Leu 14 Leucine Position 14 Glu 15 Glutamic Acid Position 15 Gly 16 Glycine Position 16 Gln 17 Glutamine Position 17 Ala 18 Alanine Position 18 Ala 19 Alanine Position 19 Lys 20 Lysine Position 20 Glu 21 Glutamic Acid Position 21 Phe 22 Phenylalanine Position 22 Ile 23 Isoleucine Position 23 Ala 24 Alanine Position 24 Trp 25 Tryptophan Position 25 Leu 26 Leucine Position 26 Val 27 Valine Position 27 Arg 28 Arginine Position 28 Gly 29 Glycine Position 29 Arg 30 Arginine Position 30 Gly 31 Glycine Position 31 N-terminus C-terminus Hydrophobic Polar Positive (+) Negative (-) Modified ### Modifications Acylated with C18 fatty diacid via γ-Glu spacer ## Research Indications The following information is derived from published scientific literature and is provided for educational and research reference purposes only.

Semaglutide works because it makes a calorie deficit easier to sustain. It suppresses appetite, slows gastric emptying, and helps you feel full longer. But it doesn’t burn fat directly, it can come with a real lean-mass loss problem, and a lot of people regain weight after stopping unless they use that appetite-suppression window to build habits. And if your real goal is fat loss and body composition, there are newer options that generally perform better.
