Retatrutide,high purity,White freeze-dried powder,XH Brand Peptide Lyophilized Powder

Short Overview

Core Research Advantages

1. Triple Target Synergistic Effect
   
   
   This peptide material can activate three core metabolic regulation pathways at the same time: GLP-1, GIP and GCGR. The combined working effect brings more comprehensive research data compared with single or dual-target peptide materials, widely used for contrast lab trials.
2. Long-lasting Activity Cycle
   
   
   Optimized molecular structure maintains stable working state inside test subjects for a long period. Researchers only need one application per week during long-term experiments, cutting down repeated operating steps and reducing extra variable interference to test data.
3. Preferential Regulation on Fat Tissue
   
   
   Mass verified lab test data shows the material mainly adjusts fat tissue status while protecting lean tissue of test subjects. It helps researchers obtain clean and accurate experimental data related to weight control without confusing muscle-related interference factors.
4. Multi-index Metabolic Observation Support
   
   
   Besides adjusting satiety signals, this material supports multi-dimensional data recording on lab models: balancing blood sugar fluctuation, improving insulin sensitivity and monitoring lipid balance of liver tissue, matching all kinds of metabolic research programs.
5. Mild Observable Responses in Trials
   
   
   Only slight and temporary gastrointestinal signals can be observed under standard research dosage. No serious abnormal performance will appear if users follow standard lab operation guides, guaranteeing stable and repeatable long-period experiment data.
6. Consistent Performance Between Batches
   
   
   Standard freeze-drying production procedures ensure uniform purity, dissolving ability and molecular activity for every production batch. There will be no deviation of test results caused by inconsistent raw material quality, suitable for parallel control group experiments and repeated verification.

Quality Control Standards

1. Core Purity Standard
   
   
   HPLC test purity of finished peptide material is guaranteed ≥99.0%. Complete spectrum chromatogram records are attached to each batch report. Single unknown impurity ≤0.3%, total unknown impurities ≤1.0%. C18 reverse-phase column with 220nm UV detection is adopted to measure purity precisely.
2. Mandatory Batch Test Items

• Spectrum molecular matching test to ensure molecular weight error within ±5 Da compared with theoretical value
• Amino acid sequence verification to match standard 39-amino acid chain completely
• Residual trace substance test following ICH Q3C standard
• Accelerated stability test under constant temperature and humidity environment
• Target binding activity test to maintain stable research performance
• 100% manual visual inspection for all finished vials before shipment to remove defective goods
• Complete batch traceability system covering raw material records, production logs, inspection data and delivery files

Step-by-Step Dissolving Guide

1. Slowly pour bacteriostatic purified water along the inner wall of the vial to avoid excessive foam
2. Tighten the vial cap fully, swirl gently in circle until all solid material dissolves completely
3. Do not shake the vial violently; fierce shaking will break molecular structure and reduce test performance
   
   
   Suggested weekly dosage for animal model research: 0.05mg/kg – 0.8mg/kg, adjustable based on your experiment design and animal species

Storage & Validity Rules

Unopened Sealed Original Vials

• Long-term storage condition: Keep sealed vials at -20°C ~ -80°C, away from light and moisture
• Valid storage period under constant -20°C: 12 months
• Valid storage period under constant -80°C: 36 months
• Short transit stability: Keep stable performance for up to 7 days under ambient temperature below 25°C
• Avoid frequent temperature change and direct sunlight

Liquid Mixed with Bacteriostatic Purified Water

• Storage condition: Store in refrigerator at 2°C ~ 8°C
• Suggested usage period: Finish all mixed liquid within 28 days after preparation
• Do not freeze mixed liquid; repeated freezing and thawing will damage molecular stability

Shipping & Receiving Tips

1. Small trial vial orders can be delivered by standard international express for short transit distance
2. Large quantity vial orders are suggested to choose temperature-insulated packaging to maintain stable molecular state during cross-border long-distance transport
