Terms of Sale

This site is operated under the trading name PeptLot, dispatching from Guangzhou, China. Contact: sales@peptlot.com. Sales are business-to-business for laboratory research use; by ordering you confirm that you buy for research or resale to research users and that you are not a consumer. All products are supplied for laboratory research use only. Not for human or veterinary use. No dosing, therapeutic or clinical guidance is provided.

Products are supplied as described on the product page: the stated compound, strength and vial count per kit, in sealed clear glass vials. No custom or private labels, documents or packaging changes are offered. Prices are in USD per kit from the published price list (10 OCTOBER 2026); the minimum is 1 kit per SKU, any mix of SKUs, no minimum order value, no volume discounts. Prices and availability are confirmed on the Proforma Invoice issued at checkout.

Payment is in USDT only, on TRC-20, ERC-20 or BEP-20, to the address shown on your signed-in order page for the network you chose. Send the exact invoiced amount within the payment window (60 minutes). The order is paid when the transfer is confirmed on chain; screenshots never count. Underpaid, overpaid, late, wrong-network or duplicate transfers are held for manual review and never ship automatically. No cards, PayPal or bank transfers are accepted. USDT transfers are irreversible; refunds, where the rules below provide for one, are paid in USDT to a wallet you confirm in writing.

Dispatch: Within 2 days after payment is confirmed. Shipping fees follow the public rule on the Shipping page (free on every service from USD 2000 in items). Delivery estimates count from dispatch, are shown per destination, and are estimates only: No specific arrival date is promised. Tracking is provided once the parcel is handed to the courier.

You are the importer of record and responsible for duties, taxes and import requirements at destination. Shipments are declared accurately. Without cover, a parcel that customs holds, seizes or destroys is not re-shipped and not refunded. At checkout you may add Customs Reshipment Cover for 10% of the items subtotal, minimum $30, under these conditions:

• • Covers one re-shipment of the same order to an address in the same country after a customs seizure or destruction confirmed by a customs notice or the carrier's tracking status.
• • Shipping on the re-shipment is included. The re-shipment itself is not covered a second time.
• • Not a refund and not transit-loss insurance. Cannot be added after the order is placed.
• • Not valid when the buyer declines to cooperate with customs, gives an incorrect address, or refuses or fails to collect the parcel.

Every case is reviewed manually from the order page with the evidence described; nothing is credited, refunded or re-shipped automatically.

• Customs holds and seizures. You are the importer of record. A parcel that customs holds, seizes or destroys is not re-shipped and not refunded, unless Customs Reshipment Cover was added to the order at checkout. With cover, the same order is re-shipped once after a customs seizure or destruction confirmed by a customs notice or the carrier's tracking status; the reshipment itself is not covered again.
• Lost or damaged in transit. Loss or damage before delivery is reviewed case by case with the carrier's tracking and photos; a re-shipment or credit is a manual decision. Loss after confirmed delivery, refused or unclaimed parcels and address errors are not re-shipped.
• Quality disputes and refunds. A quality dispute needs an independent, publicly verifiable laboratory result that can be attributed to a sample from the order. If a genuine product quality problem is confirmed, the remedy is a replacement batch plus reasonable testing costs, or a refund of the goods — decided case by case. Freight is not automatically included and an allegation alone does not trigger a refund. Refunds are paid in USDT to a wallet the buyer confirms in writing.
• COA labelling. An in-house certificate is never presented as an independent third-party result, and every document is linked to the exact lot it describes. No report from another brand is relabelled for this one.
• Payment confirmation. A payment screenshot is not a payment confirmation. Only an on-chain confirmation of the exact amount on the stated network marks an order paid, and dispatch is a separate step after that.

Research-use products are not returnable once dispatched.

You are responsible for your account credentials. Referral credit (3% of the items subtotal of orders paid within 90 days of the referred account's registration; none when the referred order ships to the referrer's address or is paid from the referrer's wallet) and welcome coupons are store credit for items on this site: never cash, never USDT, not transferable, reversed when the related order is cancelled or refunded. Codes can be suspended for abuse. Eligibility and amounts are decided by the server.

To the extent permitted by law, our liability for an order is limited to the amount you paid for that order, and we are not liable for indirect or consequential loss, including loss caused by customs action, carrier delay or regulatory change at destination. Nothing here limits liability that cannot be limited by law.

These terms are version 2026-10-19. The policy snapshot stored with your order and shown on its Proforma Invoice governs that order; later changes apply only to later orders.
