Product Overview
GLP-1 S
GLP-1 S is a long-acting glucagon-like peptide-1 (GLP-1) receptor agonist approved for chronic weight management and glycemic control in adults with obesity or type 2 diabetes. It mimics endogenous GLP-1, acting on central and peripheral pathways to suppress appetite, delay gastric emptying, increase glucose-dependent insulin secretion, decrease glucagon release, and promote pancreatic β-cell growth.[1][2]
Efficacy for Weight Loss & Obesity Management
Indicated for adults with BMI ≥30 kg/m² or ≥25 kg/m² with a weight-related comorbidity.[3][2][4] In STEP 1 and STEP 3, mean weight loss at 68 weeks was 14.9% and 16.0%, respectively, vs 2.4% and 5.7% with placebo. Most participants achieved ≥10% loss, and over half achieved ≥15% loss.[1][5–7] Benefits are maintained with continued therapy; discontinuation often leads to weight regain, underscoring the need for long-term treatment.[1][5][7]
Glycemic Control & Cardiometabolic Benefits
- Significant reductions in HbA1c and fasting glucose in type 2 diabetes.[8–11][2][5]
- Lowers blood pressure, improves lipid profiles, and reduces inflammatory markers (e.g., CRP).[4][6]
- Recommended by ADA and AGA as a first-line pharmacologic option for weight management in adults with obesity and/or type 2 diabetes.[11][2]
Cardiovascular & Renal Outcomes
- Reduces MACE, cardiovascular mortality, and all-cause mortality in high-risk populations per large trials/meta-analyses.[12–15][4]
- Kidney-protective effects; recommended for CKD with type 2 diabetes.[12][15][2]
Safety & Tolerability
- Most common AEs are GI (nausea, vomiting, diarrhea); discontinuation rates similar to placebo in trials.[5–7]
- Rapid weight loss may increase risk of gallstones/hepatobiliary disorders.[6]
- No consistent link with increased cancer or psychiatric AEs confirmed.[7]
- Low hypoglycemia risk as monotherapy.[8–10][2]
Clinical Considerations
- Use alongside nutrition and physical-activity interventions.[1][2][6]
- Plan for long-term therapy; counsel on potential weight regain after stopping.[1][5][7]
- Individualize therapy based on comorbidities, preferences, and access.[2][7]

Storage & Handling (Research Use)
- Lyophilized (dry) peptide: Store sealed at −20 °C (long-term). Short-term storage up to 2–3 weeks at 2–8 °C is acceptable.
- After reconstitution: Store at 2–8 °C and use within 7 days, or aliquot to sterile vials and freeze at −20 °C for up to 3 months.
- Light & moisture: Protect from light; keep container tightly closed to avoid moisture uptake.
- Freeze–thaw: Avoid repeated freeze–thaw cycles (prepare small aliquots).
- Solvent compatibility: Use a sterile, compatible solvent per your protocol; filter-sterilize if required.
- Labeling: Clearly label aliquots with concentration, solvent, and preparation date.
Storage guidance is general for research peptides and may be adapted to your lab SOP.
