VIP 10mg

VIP 10mg(Vasoactive Intestinal Peptide) is a multifunctional neuropeptide composed of 28 amino acids, belonging to the secretin-glucagon peptide family. This product is a 10mg lyophilized powder, white and loose in appearance, with a purity suitable for scientific research and experimental applications. VIP is widely distributed in the central nervous system and peripheral tissues, possessing various physiological functions including regulating vasodilation, immune response, anti-inflammatory reactions, and metabolic homeostasis. In recent years, its application in lipid metabolism and weight regulation has also attracted attention. This product is recommended to be stored at -20°C in a dry, light-protected environment to maintain peptide stability.

一.Multi-system regulatory capacity

VIP acts as both a neurotransmitter and a circulating hormone in the body, participating in the regulation of the following systems:

1. Cardiovascular system

• Potential vasodilatory effect, increasing local tissue blood flow
• Lowering arterial blood pressure
• Stimulating myocardial contractility

2. Nervous system

• Inhibiting microglia activation, exerting neuroprotective effects
• Reducing dopaminergic neuronal apoptosis
• Regulating circadian rhythms

3. Immune system

• Inhibiting the release of pro-inflammatory factors
• Regulating T cell differentiation (inhibiting Th17, promoting Treg)
• Participating in antiviral immune responses

4. Digestive system

• Relaxing gastrointestinal smooth muscle
• Regulating intestinal secretion function
• Stimulating pancreatic exocrine secretion

5. Metabolic system

• Promoting glucose-dependent insulin secretion
• Increasing blood flow to adipose tissue
• Participating in energy balance regulation

二.Limitations

It should be objectively noted that natural VIP molecules possess the following characteristics, which need to be considered in experimental design:

• Extremely short plasma half-life: approximately 2 minutes, resulting in a limited duration of action in vivo.
• Poor metabolic stability: easily degraded by proteases.
• Limited stability after reconstitution: degradation rate accelerates in solution.

These characteristics have prompted researchers to develop various VIP derivatives and optimization strategies, such as lipid modification, fusion protein technology, and alanine scanning substitution, to improve their metabolic stability.

The following are typical analytical certificate data for VIP 10mg lyophilized powder, covering core quality control indicators such as product physicochemical properties, purity, content, and biosafety. All tests are performed according to industry-standard methods.

1.Production and Quality Control Systems
Companies specializing in peptide products typically have established relatively complete production and quality control systems:

2.Product Line Richness

• Weight loss peptides: Semaglutide, Tirzepatide, and Retatrutide
• Anti-aging peptides: MOTS-c, SS-31, Semax and Selank
• Synthetic peptides: VIP, GHRP series, beauty peptides, etc.

This breadth of product lines allows customers to achieve "one-stop purchasing," reducing our management costs.

3.Customization Service Capabilities
 

• Specification Customization: Different purities, different packaging specifications
• OEM/ODM: Private label manufacturing and formulation development

1.Packaging Method

VIP 10mg products typically employ a multi-layer packaging structure to ensure product stability during storage and transportation.

• Inner Packaging: The product is directly contained in a transparent glass vial, sealed with a butyl rubber stopper, and then further sealed with an aluminum-plastic cap. This packaging method provides excellent airtightness, effectively preventing the ingress of moisture and oxygen. The vial material meets pharmaceutical-grade standards and does not absorb peptides.
• Middle Protection: An aluminum foil bag or plastic sealing film can be added to the outside of the vial for light protection and secondary moisture protection.
• Outer Packaging: Multiple vials are placed in a cardboard box or carton lined with shock-absorbing material. The cardboard box material is typically high-grammage art paper or corrugated cardboard.
• Specifications: Common packaging specifications are 10mg/vial and 10 vials/box. The minimum order quantity is usually 10 vials, but customized packaging can also be provided according to customer requirements.

2.Storage Requirements

The storage environment of VIP 10mg lyophilized powder directly affects the product's shelf life and activity retention.

• Long-term storage: Unopened lyophilized powder should be stored at -20℃, avoiding repeated opening and closing of the refrigerator to prevent temperature fluctuations. Under these conditions, the product's shelf life can reach 12-36 months.
• Short-term storage: If stored at 2-8℃, it is recommended not to exceed 1 month. The lyophilized powder should be sealed in its original vial to prevent moisture absorption.
• Storage during use: The product's stability decreases significantly after reconstitution. At 2-8℃, it can typically only be stored for 2-7 days. For longer storage, it should be aliquoted according to single-use dosage and frozen at -20℃ or -80℃, avoiding repeated freeze-thaw cycles.
• Storage environment requirements: The warehouse should be kept clean, dry, and well-ventilated, with dust-proof, insect-proof, and rodent-proof facilities. It must not be stored in the same warehouse as toxic, harmful, odorous, or volatile substances.
