We offer various types of peptides，are widely used in life science research, drug discovery, cosmetics, anti-aging medicine, and functional health industries.about the peptides，we can provide the good quality，the good price.Customers who have ordered our products（peptides）have had very good feedback.
World wide relaible buyers can contact us about the peptides.
1. Superior Product Quality
Product quality is the foundation of our business. Peptides are synthesized using solid-phase peptide synthesis (SPPS), then purified through HPLC and confirmed by mass spectrometry (MS).
Each batch includes a Certificate of Analysis (COA) with key data:
• Purity (HPLC)
• Molecular weight (MS)
• Water content
• Residual solvents
• Microbial limit (if applicable)
For clients with higher regulatory demands, we also provide third-party testing reports, endotoxin (LAL) data, and stability studies upon request.
2. Customization & R&D Support
We offer flexible custom synthesis services, supported by an experienced R&D team. Whether you’re looking for novel peptide sequences, cosmetic-grade purity, or modified molecules (e.g., PEGylation, acetylation), we can deliver high-quality results on time.
Our services include:
• Custom peptide synthesis (mg to kg scale)
• Peptide modifications and labeling
• Small molecule synthesis
• Project-based research and scale-up
We work closely with our clients to ensure technical feasibility, fast delivery, and cost control throughout the development cycle.
3. Wide Product Portfolio
We supply a comprehensive and expanding product range:
• Peptides: GLP-1 analogs (e.g., Semaglutide, Tirzepatide, Retatrutide), cosmetic peptides (e.g., Acetyl Hexapeptide-8, Matrixyl), anti-aging peptides, research peptides.
• Small Molecules: Nootropics, NAD+ boosters (e.g., NMN, NR, NADH), and intermediates.
• Biochemicals: Amino acid derivatives, enzyme co-factors, custom reagents.
New products are launched regularly to meet evolving market needs. We also support batch reservations for clients with ongoing or seasonal demand.
IGF - DES Chemical Product Introduction
IGF - DES, often referred to as Des(1 - 3)IGF - 1, is a modified form of insulin - like growth factor 1 (IGF - 1). IGF - 1 is a protein naturally present in humans, playing a crucial role in childhood growth and maintaining anabolic effects in adults. The "Des" in its name indicates that it is a truncated peptide, with the first three amino acids at the N - terminus of the normal IGF - 1 molecule removed.
IGF - DES binds to the IGF - 1 receptor and insulin receptors with different affinities compared to IGF - 1. Due to its smaller size, it has a significantly shorter half - life, which may lead to a more localized effect and reduced systemic availability. This peptide is mainly studied for its potential in promoting tissue growth and repair, especially in muscles. It is of great interest in research related to muscle regeneration, wound healing, and cell growth.
In the medical research field, IGF - DES shows potential in multiple aspects. It is being studied for its neuroprotective and neuroregenerative properties, which could be beneficial for treating neurological conditions such as Parkinson's disease, multiple sclerosis, and spinal cord injuries. Research on autism spectrum disorders also includes IGF - DES, as it may affect neurological development and synaptic function, potentially providing new treatment approaches. Additionally, considering its role in cellular growth and neuroprotection, it might enhance cognitive functions and help mitigate age - related declines in memory and learning abilities.
In the market, IGF - DES products are usually provided as filtered, sterilized white lyophilized powders. For example, some products are produced by dialyzing and lyophilizing from a 50mM acetic acid buffer solution containing IGF - DES. They can be stored at room temperature for 3 weeks or at - 18°C for long - term storage. After re - dissolution, they can be stored refrigerated at 4°C for at least 2 - 7 days.
Overall, IGF - DES holds great potential in both research and possible future therapeutic applications, though further studies are still needed to fully explore and understand its functions and applications.
