Undissolved Lyophilized Powder (Normal)
Color: Pure white to off-white; uniform in color with no yellowing, specks, or discoloration;
Form: Vacuum-lyophilized cake; fluffy and porous; crisp and easily friable (minor powdering due to transport is normal); the powder is dry and crisp, showing no signs of moisture absorption, softening, or adhesion to the vial walls;
Packaging: Transparent vial with aluminum cap and rubber stopper; securely sealed with no air leaks or mold spots; free from foreign odors.

Mechanism of Action and Key Benefits
Simultaneously activates both GLP-1 and GIP metabolic pathways to achieve multi-faceted metabolic regulation:
Potent appetite control and prolonged satiety: Delays gastric emptying and signals satiety to the brain, naturally reducing overall food intake and curbing binge eating and carbohydrate cravings;
Optimizes insulin resistance: Enhances insulin sensitivity and stabilizes both fasting and postprandial blood glucose levels; suitable for individuals with impaired glucose tolerance, PCOS, or Type 2 diabetes;
Fat loss and body shaping: Prioritizes the reduction of visceral fat and waist circumference, regulates blood lipids, and helps overcome weight-loss plateaus;
Additional benefits: Alleviates weight-related metabolic complications such as hypertension, hyperlipidemia, and sleep apnea.

Storage Guidelines and Shelf Life
Unopened lyophilized powder: For long-term storage, keep frozen at -20°C, protected from light (shelf life: 12–24 months). For short-term storage, keep refrigerated in a cool, dark place; avoid high temperatures, direct sunlight, and repeated freeze-thaw cycles, as exposure to high temperatures can easily cause oxidation, yellowing, and degradation.

Notes on Usage Cycles and Receptor Desensitization
Receptor desensitization is highly likely to occur after 8–12 weeks of continuous use, manifesting as reduced satiety and a weight-loss plateau; this is a normal physiological adaptation rather than a sign that the medication has stopped working. Standard protocol involves 8–12 weeks of continuous use followed by a 2–4 ​​week break to reset receptor sensitivity. Alternatively, long-term low-dose maintenance may be used; do not blindly increase the dosage in an attempt to overcome reduced responsiveness.
