Answers for Every Step of Your Order

You can place an order directly from our Buy Peptides catalog. Browse the catalog, add products to your cart, and proceed to checkout.

If you need help during the process, email support@purelabpeptides.com and we will walk you through it.

Available payment methods and any associated discounts vary. The options currently supported for your order are displayed at checkout. Options may include:

• Alternative payment methods — may include Zelle, Venmo, or Cash App when supported
• Credit or debit card — may appear when card processing is available

Do not send payment until you receive the instructions shown during checkout or in your order confirmation. Your order enters fulfillment after payment is received and confirmed. Available methods may change without notice.

No. An account is not required; guest checkout is available. Creating an account is optional and can provide faster reordering, shipment tracking history, saved shipping addresses, and access to past orders.

If your order has not yet been packed, email support@purelabpeptides.com as soon as possible with your order number and we will do our best to accommodate the change.

Once a shipping label has been generated, modifications and cancellations are no longer possible.

Yes. For research programs, institutional buyers, and resellers, we offer tiered pricing on bulk and wholesale orders. Email support@purelabpeptides.com with the products and quantities you are interested in, and we will respond with custom pricing.

For first-time customers and large orders, we may run a brief verification step to protect against fraud. This is uncommon and usually resolves within a few hours during business hours. If your order is being reviewed, you will receive an email from our team.

Not at this time. We ship exclusively within the United States, including Alaska, Hawaii, and APO/FPO addresses. We are not currently able to fulfill international orders.

Orders confirmed and paid in full before 12:00 PM Eastern Time on a business day are dispatched the same day. Orders placed after the cutoff, on weekends, or on federal holidays ship the next business day. You will receive an email with tracking when your label is generated.

Transit time depends on the method selected at checkout:

• USPS Priority Mail — 2–5 Business Days
• FedEx 2Day — 2 business days
• FedEx Standard Overnight — next business day

Weekend timing: shipping methods count business days only, so Friday overnight orders are delivered the following Monday unless a Saturday-delivery service was arranged in advance. Delivery dates are carrier estimates and can be affected by weather, holidays, and peak periods.

Free USPS Priority delivery is available on orders of $200 or more. For orders below that threshold or for expedited methods, the exact rate shown at checkout controls. Typical rates are:

Yes. Every shipment goes out in plain, unbranded packaging with a generic return address. Nothing on the exterior identifies the contents or product type.

Standard shipments do not require a signature. For added security, select a signature-required FedEx option at checkout when it is available.

Our peptides are shipped lyophilized (freeze-dried) and are stable at ambient temperatures for normal transit. Cold packs are not standard. If your destination is experiencing extreme heat, consider FedEx Standard Overnight to minimize transit time.

USPS Priority Mail includes up to $100 of insurance by default. FedEx services include declared-value coverage based on the shipment. If an order is lost or damaged in carrier custody, contact us within the applicable seven-day reporting window so we can review the evidence and carrier findings under our Shipping & Returns policy.

You will automatically receive an email with your tracking number when the shipping label is generated. If you have an account, the tracking number is also available in your order history.

Probably not. Carriers sometimes go a day or two between scans, especially during peak periods or between pickup and the first sorting facility. Allow 48 hours. If there is still no movement after five business days, email us with your order number.

If your order has not yet been packed, email us immediately and we can usually update the destination. Once a label has been generated, the carrier controls any rerouting.

Customers are responsible for providing a complete and accurate shipping address. Pure Lab LLC is not responsible for delay, loss, misdelivery, non-delivery, or return-to-sender caused by an incorrect or incomplete address. Orders shipped to the address entered at checkout are considered correctly fulfilled, so please review every address field before submitting the order.

Check the mailbox, front door, parcel locker, lobby, building office, household members, and nearby neighbors. If the package is still missing after 24 hours, contact the local carrier office and ask where the delivery scan was recorded, then email us with your order number and any carrier findings.

If the carrier confirms delivery to the complete address entered at checkout, the order is considered delivered. Address errors remain subject to the customer-responsibility policy below.

No. Our peptides are sold strictly for in-vitro laboratory research and development purposes only. They are not drugs, food, cosmetics, or dietary supplements and are not intended for human or veterinary use, ingestion, injection, or any form of administration.

Our peptides are typically ≥99% purity, confirmed through HPLC and mass spectrometry analysis as part of our quality-control process. The batch-specific result on the applicable Certificate of Analysis controls.

Yes. COAs are available for the products we ship. If the current COA is not visible on the product page, email support@purelabpeptides.com with the product and batch details.

Storage conditions vary by compound. As a general laboratory guideline:

• Lyophilized (unreconstituted) peptides — store sealed at -20°C for long-term storage or 2–8°C for shorter periods
• Reconstituted peptides — store at 2–8°C and follow the compound-specific stability information
• Avoid repeated freeze-thaw cycles, which can degrade peptide integrity

Our peptides ship lyophilized (freeze-dried) as a stable powder unless the individual product page expressly states otherwise.

Lyophilized peptides can show minor cosmetic variation between batches, including differences in cake structure, color shade, or minor particulate consistent with specifications. If you have a concern, send us a photo and the batch number for review.
