      • The importance of peptides:
      • Many active substances in the human body are in the form of peptides. Peptides are involved in various fields of human hormones, nerves, cell growth and reproduction, and their importance is to regulate the physiological functions of various systems and cells in the body, activate the relevant enzyme systems in the body, promote the permeability of intermediate metabolic membranes, or control DNA transcription or affect specific protein synthesis, and ultimately produce specific physiological effects. Peptides are important substances involved in various cell functions in human body. Peptides can be synthesized into cells and regulate their functional activities. Peptides act as neurotransmitters in the body, transmitting information. Peptides can be used as transportation tools in the human body to transport various nutrients and various vitamins, biotin, calcium and trace elements beneficial to the human body to the cells, organs and tissues of the human body. Peptide is an important physiological regulator of the human body, which can comprehensively regulate the physiological function of the human body, enhance and exert the physiological activity of the human body, and it has important biological functions.

     About Us

    STTY specialize in the development and global distribution of high-quality research-use-only (RUO) raw materials, including peptides, small molecules, and biochemical reagents.

    Our products are widely used in life science research, drug discovery, cosmetics, anti-aging medicine, and functional health industries.


    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.

    ECHEMI Editorial Reference
    Retatrutide is a novel triple agonist peptide of the glucagon receptor (GCGR), glucose-dependent insulinotropic polypeptide receptor (GIPR) and glucagon-like peptide-1 receptor (GLP-1R). Retatrutide inhibits human GCGR, GIPR and GLP-1R with EC50 values of 5.79, 0.0643 and 0.775 nM, respectively and mouse GCGR, GIPR, and GLP-1R with EC50 values of 2.32, 0.191 and 0.794 nM, respectively. It is an important tool for obesity research.Retatrutide potently activates the GLP-1R signaling pathway to stimulate glucose-dependent insulin secretion through activity at the GIP receptor (GIPR) or the GLP-1R.Retatrutide is a synthetic peptide with glucose-lowering effects. It is an antidiabetic agent against type 2 diabetes (T2D), stimulating insulin and suppressing glucagon secretion in a glucose-dependent manner.Retatrutide was also shown to delay gastric emptying, lower fasting and postprandial glucose concentration, decrease food intake and reduce body weight in patients with type 2 diabetes.
    Retatrutide (LY-3437943) was discovered by the American pharmaceutical company Eli Lilly and Company. It is a triple glucagon hormone receptor agonist (GLP-1, GIP, and GCGR receptors) for obesity. The 2024 Lasker~DeBakey Clinical Medical Research Award has been given to Joel Habener and Svetlana Mojsov for their discovery of a new hormone GLP-1(7-37) and to Lotte Knudsen for her role in developing sustained acting versions of this hormone as a treatment for obesity.
