Crypto orders are processed within 1–3 business days after payment is confirmed on the blockchain. SWIFT orders are processed after the wire clears, typically within 3–5 business days.
SWIFT Bank Wire Payments
QSC now accepts SWIFT international bank wire transfers in addition to Bitcoin (BTC) and USDT (ERC-20). After placing your order and selecting SWIFT at checkout, full payment instructions (beneficiary details, account and SWIFT/BIC codes) will be sent to you by email within 24 hours.
Note: Cryptocurrency (BTC/USDT) is our preferred payment method and typically processes faster than SWIFT, since crypto payments are confirmed on-chain within hours rather than the 3–5 business days a bank wire takes to clear.

Send in USD only
International wire fees are the sender’s responsibility
Allow 3–5 business days for payment to clear
If your bank asks for an intermediary bank, none is required
Step 2 — Delivery Timelines
🇺🇸 🇪🇺 🇬🇧 🇨🇦 🇦🇺 🇸🇬 🇹🇭 🇻🇳 Domestic Warehouse
Ships directly to your local carrier — no customs, no international transit.
Used for international orders or when an item is out of stock at your regional warehouse.
7–14 business days
Local carrier tracking activates after customs clearance — no activity before that is normal. Use the QSC tracking page to see full transit status.
⚠️ Split shipments: If you order multiple items and one isn’t available in your regional warehouse, it may ship separately from China. You’ll receive separate tracking numbers — packages may arrive on different dates. No extra shipping charge applies.
⚠️ China warehouse tracking: Local carrier tracking will show no activity while your package is in international transit. This only updates after customs clearance at your destination — this is completely normal. Use the QSC tracking page below to see full transit status.
QSC is one of the most recognised peptide suppliers in the global research community, making high-purity research peptides more accessible to laboratories, distributors, and researchers across more than 100 countries.
QSC operates as both a direct manufacturer and through a vetted partnership model. Core peptides are produced in-house using solid-phase peptide synthesis (SPPS), advanced purification systems, and full analytical testing. QSC also partners with rigorously vetted manufacturers to expand its catalog — ensuring every product, whether in-house or partner-sourced, undergoes the same quality control process including HPLC purity analysis, mass spectrometry, and impurity profiling.
The qscpeptide.com storefront is the dedicated US and international distribution interface for QSC products, serving researchers in North America, Europe, Oceania, Asia, and beyond. Independent purity verification on every batch is performed by Janoshik Analytical Laboratories and is publicly verifiable by batch number.
QSC maintains domestic warehouses in the United States, European Union, United Kingdom, Canada, Australia, Singapore, Thailand, and Vietnam. When your product is in stock locally, it ships domestically with no customs clearance required. If an item is not available at your regional warehouse, it will ship from QSC’s China facility — you will receive a separate tracking number and the delivery window will be 7–14 business days. Orders with multiple items may ship from more than one warehouse and arrive separately.
What purity are QSC peptides?
QSC research peptides are verified at ≥99% purity by HPLC analysis and mass spectrometry. Every product page includes a Certificate of Analysis (COA) independently verifiable via the Janoshik testing portal — not just available on request, but proactively published for every batch.
Is QSC the manufacturer or a reseller?
QSC operates as both a direct manufacturer and through a partnership model. Core peptides are produced in-house using solid-phase peptide synthesis (SPPS), purified by preparative HPLC, lyophilized, and analytically verified. QSC also partners with rigorously vetted manufacturers to expand its product range — all partner-sourced products undergo the same QSC quality control process before distribution. QSC does not source product from undisclosed or unvetted third parties.
What payment methods does QSC accept?
QSC accepts Bitcoin (BTC), USDT (ERC-20) cryptocurrency, and SWIFT international bank wire transfers for orders worldwide. After checkout you will receive payment instructions and a confirmation email with tracking information once your order ships.
For SWIFT payments, full wire instructions are sent by email within 24 hours of placing your order. A few notes: include your Order Number in the payment reference/memo field, send in USD only, international wire fees are the sender’s responsibility, allow 3–5 business days for payment to clear, and if your bank asks for an intermediary bank, none is required.
