Semaglutide 20MG

描述

Core Product Highlights
$\ge 98.5\%$ Purity via Large-Scale Solid-Phase Synthesis (Ultra-Pure SPPS Synthesis): The synthesis of large-scale peptide batches (20 mg) imposes extremely rigorous demands on temperature control and byproduct management. This product utilizes an advanced, fully automated Solid-Phase Peptide Synthesis (SPPS) technique, coupled with high-sensitivity Reverse-Phase C18 Liquid Chromatography purification. This process strictly eliminates impurities resulting from chain cleavage, racemization, and incomplete coupling, ensuring that purity remains consistently at $\ge 98.5\%$—even within large-dose packaging. This provides a pristine matrix, free from biochemical interference, for your in vitro and in vivo academic research.
Extended Half-Life GLP-1 Analog Design (Extended Half-Life via Acylation): The peptide sequence features the introduction of α-aminoisobutyric acid (Aib) at position 8 to resist rapid degradation by endogenous DPP-4 enzymes. Furthermore, a C18 fatty diacid side chain is attached to the lysine residue at position 26 via a spacer linker. This precise molecular engineering endows the peptide with exceptional albumin-binding affinity, establishing it as the industry-standard benchmark model for investigating long-acting metabolic regulation, cardiovascular protection mechanisms, and interactive pathways in neurodegenerative diseases.
Superior 20 mg Lyophilization Process with Locked Bioactivity (Advanced Lyophilization Lock): The high-capacity 20 mg peptide powder undergoes water sublimation at an ultra-low temperature of $-80^\circ\text{C}$ within a near-vacuum environment, resulting in a crystalline structure characterized by dense, full, snowflake-like formations. This process not only guarantees excellent reconstitution properties (enabling complete, precipitate-free dissolution within milliseconds when combined with BAC Water) but also deeply locks the peptide’s molecular spatial conformation. This significantly mitigates the risk of thermal degradation during international transit and customs clearance—challenges often associated with large-volume packaging.

🛠️ Technical Specifications & Physical Parameters
Product Specification: 20 mg / Vial
Molecular Formula: $\text{C}_{187}\text{H}_{291}\text{N}_{45}\text{O}_{59}$

Validation Documentation: Accompanied by the manufacturer’s original High-Performance Liquid Chromatography (HPLC) purity analysis chromatogram and Mass Spectrometry (MS) molecular weight identification report (one certificate per vial; supports digital traceability via the backend system and one-click download).

❄️ Storage Requirements & Comprehensive Cold Chain Protection (Storage & Shipping Ironclad Policy) — Laboratory Storage Protocol: Upon receipt, and prior to reconstitution, the product must be immediately stored in an ultra-low temperature, explosion-proof, research-grade freezer maintained between $-20^\circ\text{C}$ and $-80^\circ\text{C}$. It must be kept protected from light and moisture at all times. It is strictly prohibited to store this product in standard retail refrigerators or administrative office environments lacking specialized equipment. Given the high dosage of the 20 mg specification, it is strongly recommended that—following reconstitution—the solution be strictly aliquoted (subdivided) and frozen to prevent denaturation of the peptide’s secondary structure caused by repeated freeze-thaw cycles.
Pharmaceutical-Grade Cold Chain Direct Shipping: We strictly adhere to this platform’s “Shipping and Order Scheduling Policy.” The 20 mg Semaglutide product is shipped via express courier in a high-density, extra-thick foam container, utilizing the manufacturer’s proprietary, high-capacity, international-grade cold packs. (During hot seasons or for shipments to remote regions, dry ice transport is mandatorily included.) This ensures that the peptide molecules remain in a fully frozen, “activity-locked” state throughout their journey, regardless of the distance traveled.
