FAQs

Raw material specifications and standards

A1: Our standard peptide raw materials have a purity of ≥95% (HPLC), and we offer options of ≥98% and ≥99%. Each batch comes with a Certificate of Analysis (CoA) including purity and solvent residue data. For other product quality requirements, please contact our sales team.

A2: Yes. We provide 10mg–100mg evaluation samples for most standard products. A nominal sample fee may apply, which can be deducted from subsequent bulk orders.

A3: We follow ISO quality management system requirements and implement strict process control and validated analytical methods (HPLC, MS) to ensure full traceability from synthesis to release.

Semi-finished/finished product formulations

A4: We offer modular semi-finished product bases, such as peptide serum bases, emulsion systems, gel matrices, and cream bases. These are pre-optimized for stability and compatibility, allowing you to customize them for your brand according to your needs.

A5: Absolutely. Our technical team can adjust the rheology, texture, and absorption feel according to your market preferences and regulatory requirements.

A6: Yes, our formula development has fully considered broad compatibility. We can provide compatibility test data upon request and recommend the best combination solutions.

Custom synthesis and development

A7: For custom synthesis of new sequences, the standard development cycle is 8–12 weeks, including synthesis, purification, characterization, and small-batch delivery. An expedited service is available for urgent projects.

A8: Yes, we specialize in advanced peptide modifications, including cyclization, lipidation (such as palmitoylation), PEGylation, and fluorescent labeling. Our team will provide advice on feasibility and structural optimization.

A9: We offer flexible MOQs; research-grade custom peptides can be ordered starting from 10mg, and we support scaling up to kilogram quantities.

Legal and compliance

A10: Yes, we ensure that our products comply with EU Cosmetics Regulation (EC) No 1223/2009, US FDA guidelines, and ASEAN Cosmetics Directives. MSDS, CoA, and certificates of conformity are available upon request.

A11: We provide regulatory support services, including ingredient safety dossiers, stability testing data, and formulation documentation, to assist you in completing local market registration.

Logistics and After-Sales

A12: We typically deliver under FOB Shanghai/Shenzhen/Qingdao terms, but we can also arrange CIF/DAP terms upon request. We cooperate with reliable international carriers and provide a complete set of shipping documents.

A13: Absolutely. Our after-sales support includes troubleshooting formula issues, stability guidance, and application training. A dedicated account manager will serve as your primary point of contact.

Collaboration and Communication

A14: Yes. We routinely sign a mutual non-disclosure agreement (NDA) before technical or business negotiations to protect your intellectual property and confidential information.

A15: The ownership of intellectual property rights will be clearly defined in the development agreement. Typically, background intellectual property belongs to each party, while foreground intellectual property may be jointly owned or exclusively licensed according to the agreement.
