QSC manufactures and distributes research-grade peptides globally. Due to the sensitivity of lyophilized peptides β including cold storage requirements, contamination risk, and analytical validation β all sales are final and no refunds are issued. QSC provides one free reshipment or store credit in verified cases of customs seizure. All products are sold strictly for laboratory research use only.
Last updated: July 2026
1. Peptide Quality Guarantee
All QSC peptides undergo rigorous analytical testing to confirm the stated purity specification (β₯99% where listed), correct molecular weight and chemical identity, and batch-to-batch consistency. Certificates of Analysis (COAs) are published on every product page for transparency and batch verification, independently verifiable via the Janoshik portal.
2. All Sales Final β No Refunds
All sales are final. QSC does not offer refunds under any circumstances. Due to contamination and cold-chain sensitivity, peptides cannot be returned or refunded once an order has been placed and payment confirmed.
If your order is seized by customs, QSC provides one free reshipment or store credit β see Section 6 below.
Orders Cannot Be Changed After Placement
Once an order is submitted and payment is confirmed, it cannot be modified, cancelled, or amended. This includes changes to items, quantities, shipping address, or any other order details. Please review your order carefully before completing payment.
Damaged, Defective, or Incorrect Items
Must be reported within 7 days of delivery. Verified claims are resolved via replacement shipment at QSC’s discretion. Photo documentation and batch details are typically required. Refunds are not available β replacement only.
Out-of-Stock Items
In the rare event that an ordered item becomes unavailable after payment is confirmed, QSC will issue store credit for use on a future order. Refunds are not available.

Custom peptide synthesis or made-to-order batches
Opened or reconstituted vials
Unopened vials and sealed products

Peptides are highly sensitive biomaterials. Compromised items cannot be guaranteed for research validity and cannot be accepted for return.

Varies by country
Orders are fulfilled from the warehouse nearest to the delivery address based on inventory availability. If a product is not in stock at your regional warehouse, it will be fulfilled from QSC’s China manufacturing facility. If one item is available domestically and another is only stocked in China, you will receive separate tracking numbers and packages may arrive on different dates. All shipments are covered by QSC’s standard reshipment guarantee β no additional shipping charge applies to split shipments.
Tracking
Tracking information is emailed within 1β4 business days of payment receipt and is also accessible via your account dashboard at qscpeptide.com. Track your order at: qscpeptide.com/track-order.
Standard local carrier tracking β updates normally from dispatch to delivery. No customs or international leg.
π¨π³ China Warehouse
Warehouse dispatch β customs β final delivery
Local carrier tracking activates only after customs clearance at the destination country. No local carrier activity before that is completely normal. Full transit status visible on the QSC tracking page.
β οΈ China warehouse β why local carrier shows no activity: Your package travels through international transit before reaching your local carrier. Local carrier tracking will show no activity during this leg β this is completely normal and does not mean your package is lost. Use the QSC tracking page for full transit status. There is typically a 1β3 business day gap between customs clearance and when your local carrier begins scanning the package.
β οΈ Split shipments: If your order contains items from both a domestic warehouse and the China warehouse, you will receive separate tracking numbers. Packages may arrive on different dates β this is expected and does not indicate a problem with your order.
QSC is not responsible for carrier delays, customs inspections, or force majeure events beyond our control.

QSC provides one free reshipment or store credit for a future order β at the customer’s choice β in verified cases of:

Reshipment Exclusions
The reshipment guarantee does not apply in cases involving an incorrect or incomplete shipping address, missing apartment/unit number or postal code, false recipient information, failure to collect a parcel from the carrier, or customer-requested delivery changes. Accurate shipping details are the customer’s sole responsibility.
