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.

Retatrutide is a novel triple agonist peptide drug that, by simultaneously activating GLP-1, GIP, and GCGR receptors, has the potential to improve blood sugar control, promote weight loss, and improve metabolic syndrome. Clinical trials have shown significant weight loss effects, with an average weight loss of up to 24.2% at the highest dose, and side effects such as nausea and vomiting can be mitigated by gradually increasing the dosage.

Main Effects:
• Promotes weight loss: Retatrutide regulates appetite and energy expenditure by activating three key receptors (GLP-1, GIP, and GCGR), resulting in significant weight loss.
• Improves blood sugar control: By mimicking the effects of hormones such as glucagon and insulin, Retatrutide helps regulate glucose metabolism and insulin secretion, thereby improving blood sugar levels.
• Improves metabolic syndrome: As a drug that acts on multiple receptors simultaneously, it is expected to have a synergistic improvement effect on metabolic syndrome, including obesity and type 2 diabetes.
