Core Molecular Specs & Technical Index
Basic Properties and Structural Characteristics
Glucagon like peptide 1 over the counter products refer to the synthetic GLP-1 (7-36) amide or GLP-1 (7-37) variants, typically supplied as lyophilized white powder. The molecular weight ranges from 3298.7 to 3350.8 Da depending on the specific sequence. High-purity material must exhibit a peptide content above 95% with acetate or trifluoroacetate counterion content clearly stated on the certificate of analysis.
Purity and Solubility Specifications
Professional B2B buyers require HPLC purity of ≥98% for research-grade material and ≥99% for cosmetic formulation use. The peptide demonstrates excellent solubility in water at 1-10 mg/mL after gentle reconstitution. Storage conditions demand -20°C lyophilized stability for 24 months and 2-8°C reconstituted stability for 7 days when protected from light.
- Purity threshold: Minimum 98% by HPLC with single impurity below 0.5%
- Counterion content: Acetate or TFA clearly quantified on CoA
- Water content: ≤5% by Karl Fischer titration
- Endotoxin level: ≤1.0 EU/mg for research applications
- Peptide sequence confirmation: Mass spectrometry verification within ±0.5 Da
Industry data from the Peptide Therapeutics Foundation indicates that over 72% of bulk peptide procurement failures stem from inadequate purity verification and improper storage documentation. GLP-1 peptides with certified purity above 98% demonstrate 40% longer stability in lyophilized form compared to lower-grade alternatives.
Manufacturing & Quality Control
Production Process and Purification
Glucagon like peptide 1 over the counter manufacturing follows solid-phase peptide synthesis (SPPS) using Fmoc chemistry. The process includes resin loading, sequential amino acid coupling, cleavage, and global deprotection. Preparative HPLC purification achieves >98% purity with two-stage gradient elution. Final lyophilization under controlled vacuum ensures consistent cake appearance and residual solvent levels below ICH guidelines.
Third-Party Testing and Certification
Each batch undergoes independent third-party analysis including HPLC, MS, amino acid analysis, and peptide content determination. Certificates of analysis provide full transparency on all quality parameters. ISO 9001:2015 certified facilities maintain strict environmental controls and batch traceability systems.
- ISO 9001:2015 – Quality management system certification
- GMP compliance – Good manufacturing practice for pharmaceutical intermediates
- MSDS documentation – Material safety data sheet for international shipping
- Stability studies – Accelerated and real-time stability data available
- Heavy metal testing – ICP-MS analysis for 10 elemental impurities
