Before you order
How do I compare products?
Compare the full product name, listed strength, pack quantity and price. Different strengths may be separate listings. Resolve any unclear specification before purchase.
Can I request batch documents?
Ask which documents are available for the product and lot intended for your order. Match the batch identifier and report details using the quality checklist.
Is there a universal purity or certification claim?
No. Use the documentation supplied for the particular material. Website imagery and category names do not establish a product’s test results or certification.
What quantity can I buy?
All 51 catalog products are available to order. One box is one kit of 10 vials. Choose the number of kits on the product page; for a larger project, use Wholesale Inquiries.
Where do you ship, and what does shipping cost?
We ship worldwide for US$50 per parcel of up to four boxes. One box is one 10-vial kit: 1–4 kits cost US$50 to ship, and 5–8 kits cost US$100. Review the total at checkout and see Shipping & Delivery.
How long does delivery take?
Preparation takes 1–2 days after payment is confirmed. Transit is estimated at 7–14 days after dispatch; the two stages are separate.
Payment and order support
Why do you accept cryptocurrency only?
We use one quote and verification process for orders from supported destinations. You receive an exact amount, network and deadline and can keep the transaction ID with your order. Card details are not collected by this store. Read the payment explanation and examples, including fees and refund limitations, before deciding to pay.
Which payments can I use?
USDT on TRC20, BTC on Bitcoin mainnet, and ETH on Ethereum mainnet. Available currencies are shown at checkout. See the payment guide.
Does placing an order mean it is paid?
No. Your order gives transfer instructions and remains on hold while payment is verified. Keep your transaction ID and order number.
What if the quote expires?
Stop before sending a new transfer and contact support. If you already paid, provide the transaction ID. An expired quote is not automatically replaced.
Can I cancel an order?
Yes. Cancellation is free within 24 hours of placing the order. Email huizhou99888@gmail.com or use the inquiry form with your order number.
When will a refund arrive?
Refunds are expected to reach your wallet within 7 days after the cancellation or refund is confirmed. We will confirm the receiving address and network before transfer. See Returns & Order Support.
What if an item arrives damaged?
Damaged items are replaced free of charge. Email huizhou99888@gmail.com with your order number, affected item, a description and available photographs, or use the inquiry form.
Are instructions for personal use provided?
No. This catalog is for laboratory research and does not provide human or veterinary dosing or administration instructions.
