What is GLP-1 (S) 5mg used for?
GLP-1 (Glucagon-Like Peptide-1) is a research compound studied for its role in metabolic regulation, glucose homeostasis, and appetite signaling. This product is strictly for laboratory and in-vitro research use only and is not intended for human or veterinary use.
Every batch undergoes triple-batch analysis using HPLC-MS for composition, purity and identity confirmation, plus USP <85> endotoxin testing and USP <71> sterility testing. Full CoA lab reports are available on every batch upon request.
Store lyophilized GLP-1 at -20°C for long-term storage. Post-reconstitution, refrigerate at 2–8°C and use within 8 weeks, per our published 8-week stability study.

Premium purity plus rigorous testing. Nothing else.
HPLC-MS Analysis
Composition Verification
🔬
✓ Confirms peptide identity✓ Quantifies purity percentage✓ Detects degradation products
Industry gold-standard mass spectrometry confirms you receive exactly what’s on the label — every single batch.
USP <85> Endotoxin Test
Safety Validation
🛡️
✓ Detects bacterial endotoxins✓ Limits pyrogen contamination✓ Required for research-grade compounds
LAL testing on every batch ensures endotoxin levels meet strict research-grade standards for reliable in-vitro work.
USP <71> Sterility
Contamination Control
✨
✓ Tests for microbial contamination✓ Validates aseptic processing✓ Ensures research integrity
Full sterility testing confirms absence of aerobic bacteria, anaerobic bacteria, and fungi — critical for research validity.
Lyophilized Format
Stability & Shelf Life
❄️
✓ Extended stability at -20°C✓ Protects peptide structure✓ Easy reconstitution
Freeze-dried format preserves molecular integrity during storage and transport, delivering maximum viability upon reconstitution.
USA Vialed
Domestic Quality Control
🇺🇸
✓ Formulated & vialed in the US✓ Strict domestic oversight✓ Traceable supply chain
Every compound is processed and finished domestically — not outsourced to unverified overseas facilities.
Triple-Batch Analysis
Consistency Assurance
📊
✓ Three independent tests per batch✓ Cross-validates results✓ Published CoA on request
Most suppliers test once. We test three times per batch. Redundant analysis eliminates false-positive results that compromise research.

Frequently Asked Questions
Everything you need to know before placing your order.
Order GLP-1 5mg
What is GLP-1 (S) and what is it used for in research?
GLP-1 (Glucagon-Like Peptide-1) is an endogenous incretin hormone studied extensively for its role in glucose-dependent insulin secretion, appetite regulation, and metabolic homeostasis. Research applications include in-vitro studies on pancreatic beta cell function, intestinal cell differentiation, and obesity-related metabolic pathways. For qualified research use only.
Is this product third-party lab tested?
Yes. Every batch undergoes triple-batch analysis using HPLC-MS for composition, purity and identity, USP <85> endotoxin testing, and USP <71> sterility testing. Certificate of Analysis (CoA) documents are available for every batch upon request.
How should GLP-1 5mg be stored?
Lyophilized GLP-1 should be stored at -20°C for long-term stability. Post-reconstitution, refrigerate at 2–8°C and use within 8 weeks. Peptide Crafters has published an 8-week stability study confirming post-reconstitution viability at refrigerated temperatures.
