What's your minimum order quantity(MOQ)?
For catalog peptides, our MOQ starts at 1 box and 1g for research-grade raw materials. For custom synthesis, MOQ depends on the sequence complexity — typically 5mg for standard peptides.
How long does custom peptide synthesis take?
Standard custom synthesis takes 5–10 business days for sequences up to 30 amino acids at research grade. GMP-grade synthesis typically requires 3–6 weeks including full QC documentation. Express service is available for select catalog peptides.
What purity levels do you offer?
We offer research-grade (≥95% by HPLC), pharmaceutical-grade (≥98%), and GMP-grade (≥99%) peptides. Higher purity levels are available upon request for specific applications. All purity claims are verified by RP-HPLC.
Do you offer OEM and private label services?
Yes. We offer full OEM services including custom synthesis, formulation, fill-finish, and private label packaging. We can produce under your brand name with your label design. Minimum quantities and lead times vary by product type — contact us for a tailored quote.
What countries do you ship to?
We ship to 30+ countries worldwide. All international shipments include proper customs documentation, MSDS, and CoA. Cold-chain shipping with dry ice or liquid nitrogen is available for temperature-sensitive peptides. We handle all export compliance.
What payment methods do you accept?
We accept PayPal, credit card and USDT as payment method.
