Company & Legitimacy Questions
Is Shanghai Apeptide Co., Ltd a real licensed company?
Yes. We are a legally registered and licensed manufacturer based in Shanghai, China. Our full company name is Shanghai Apeptide Co., Ltd. We hold all required licenses for peptide synthesis, purification, and export. You can verify our registration through Chinese business databases upon request.
Where is your physical facility located?
Our headquarters and synthesis facility are located at:
No. B Room 326, Jinhai Road 2588
Pudong District, Shanghai, China
Postal Code: 201209
Qualified clients are welcome to schedule facility visits and audits by appointment. We have nothing to hide.
Are you a broker or a real manufacturer?
We are a real manufacturer. We own and operate our synthesis facility in the Pudong District. We do not buy from other suppliers and resell. Every peptide you receive from us is synthesized, purified, and packaged in our own facility. That means better prices, better quality control, and better accountability.
Do you have a USA office or warehouse?
We currently serve the USA market directly from our Shanghai facility. This allows us to maintain quality control and offer factory-direct pricing. We do not have a USA warehouse at this time. However, our express shipping delivers to most USA addresses within 5–8 business days.
Can I verify your business license?
Absolutely. Contact our compliance team, and we will provide our business registration documents for your verification. Serious wholesale clients can also request a video tour of our facility.
Product & Quality Questions
What purity level do your peptides meet?
All our peptides are tested at 99%+ purity via High Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS). Most batches actually exceed 99.2%. We provide batch-specific Certificates of Analysis (COAs) with every order.
Do you provide third-party testing reports?
We provide our own HPLC and MS reports from our in-house quality control lab. For an additional fee, we can arrange independent third-party testing before shipment. Many wholesale clients also conduct their own testing upon arrival and have confirmed our results.
What happens if I test the product and purity is below 99%?
We stand behind our quality. If an independent certified lab tests your product and finds purity below 98%, we will issue a full refund or replacement. Contact our quality team with the testing report to initiate the process.
Do you offer custom peptide synthesis?
Yes. We synthesize custom sequences for qualified researchers and wholesale partners. Provide your sequence, desired purity, and quantity. Our technical team will respond with a quotation and estimated lead time. Custom synthesis typically takes 3–6 weeks depending on complexity.
What is the shelf life of your peptides?
Lyophilized (freeze-dried) peptides stored properly at room temperature or refrigerated have a shelf life of 12–24 months. Avoid exposure to moisture, heat, and direct sunlight. Reconstituted peptides should be used immediately or stored according to standard laboratory protocols.
How should I store my peptides upon arrival?
Unopened lyophilized vials should be stored in a cool, dry place away from direct sunlight. Refrigeration (2–8°C) is recommended for long-term storage. Do not freeze lyophilized powder. Once reconstituted, follow standard laboratory guidelines for your specific peptide.
Do your peptides come with Material Safety Data Sheets (MSDS)?
Yes. Every order includes an MSDS for each peptide purchased. You can also request MSDS documents before placing your order by emailing our technical support team.
Ordering & Pricing Questions
How do I place an order?
Browse our catalog, select the peptides and quantities you need, and submit an inquiry through our website. A sales representative will respond within 24 hours with a formal quotation, payment instructions, and estimated shipping timeline. For wholesale orders, contact our bulk team directly.
What payment methods do you accept?

Do you offer samples before I place a large order?
Yes. We strongly recommend first-time wholesale buyers order a small sample quantity (10–50 vials) to test our quality before committing to large volumes. Sample pricing is slightly higher than bulk pricing, but the cost is often creditable toward your first wholesale order. Ask your sales representative for details.
Do you have a minimum order value?
No. We welcome orders of any size. However, orders under $200 may incur a small handling fee. This fee is waived for first-time customers.

Technical & Research Questions
Are your peptides for research use only?
Yes. All products sold by Shanghai Apeptide Co., Ltd are intended for laboratory research purposes only. They are not for human consumption, therapeutic use, or clinical applications. Buyers assume all responsibility for compliant use.
Can you provide references from other USA customers?
Yes. With their permission, we can connect you with existing USA customers who can share their experience with our products and service. Contact our sales team to request references.
What is the difference between lyophilized powder and reconstituted solution?
Lyophilized (freeze-dried) powder is the standard format. It is stable, has a long shelf life, and requires reconstitution with sterile water or bacteriostatic water before use. Reconstituted solutions are pre-mixed and ready to use but have a shorter shelf life. We primarily sell lyophilized powder.
Do you synthesize all peptides in-house or outsource?
We synthesize all our peptides in-house at our Pudong District facility. We do not outsource production. This allows us to control quality, pricing, and lead times directly.
Can you provide the amino acid sequence for your peptides?
Yes. Technical data sheets including molecular weight, amino acid sequence, CAS number, and formula are available for every peptide in our catalog. Contact our technical support team to request specific sequence information.
Account & Security Questions
Is my personal information secure?
Yes. We use SSL encryption on our website. Payment processing is handled through Stripe (credit cards) or secure bank transfers. We never store credit card information. Your data is never sold to third parties.
Do you share customer information with anyone?
No. We do not sell, rent, or share customer information with third parties. Your name, address, order history, and contact information are used only to process your orders and communicate with you. See our Privacy Policy for full details.
