If you stop semaglutide, weight will be regained. Short term use of the drug has not been demonstrated in a clinical trial, so it is likely semaglutide will be a long-term commitment
In terms of side effects and tolerability, the advantage goes to Tirzepatide

Key Advantages of LC-MS/MS High sensitivity for low-abundance peptides Detects trace-level impurities and minor variants that are critical in pharmaceutical analysis Accurate mass measurement for sequence confirmation High-resolution mass spectrometry ensures precise molecular weight determination Fragmentation analysis (MS/MS) for amino acid mapping Generates sequence-specific fragment ions (b/y ions) to confirm peptide structure Ability to detect minor modifications and impurities Identifies PTMs such as oxidation, deamidation, and fatty acid conjugation Comparison with Other Techniques Why LC-MS/MS is the Gold Standard Combines chromatographic separation (LC) with mass-based detection (MS/MS) Handles complex peptide mixtures and modified analogs effectively Meets regulatory expectations for peptide characterization Provides high reproducibility and robustness for routine analysis 3: Workflow for Peptide Sequencing of GLP-1 Peptide Using LC-MS/MS The workflow for Peptide Sequencing of GLP-1 Peptide using LC-MS/MS involves a systematic process of sample preparation, separation, ionization, mass analysis, fragmentation, and data interpretation to accurately determine peptide structure and modifications

This degree of HbA1c reduction indicates enhanced insulin secretion and glucose metabolism, positioning retatrutide as a highly effective option for managing diabetes alongside weight loss
Microdosing is not an FDA-approved regimen and has not been validated in clinical trials
