FAQs

You can place an order directly on our website at purelabpeptides.com/buy-peptide. Browse our catalog, add products to your cart, and proceed to checkout.

If you need help during the process, email our support team at moc.seditpepbalerupobfsctd-8851e8@troppus and we'll walk you through it.

We accept multiple payment methods to give you flexibility — and most include a discount:

• Zelle, Venmo, and Cash App — automatically applies a 5% discount to your subtotal
• Credit and debit cards — processed via secure invoice at standard pricing

For Zelle, Venmo, or Cash App orders, you'll receive payment instructions by email after checkout. Your order ships once payment is confirmed (usually within minutes during business hours). For credit card orders, you'll receive a secure hosted payment link by email.

Yes. An account is required to place an order with us. Registering takes about a minute, and once you're set up, you'll have one-click reordering, full shipment tracking history, saved shipping addresses, and easy access to past invoices.

If your order hasn't yet been packed, yes — email us as soon as possible at moc.seditpepbalerupobfsctd-1b41c0@troppus with your order number and we'll do our best to accommodate the change.

Once a shipping label has been generated, modifications and cancellations are no longer possible. If something needs to be addressed at that point, please follow our damaged/wrong-item process when the package arrives.

Yes. For research programs, institutional buyers, and resellers, we offer tiered pricing on bulk and wholesale orders. Email moc.seditpepbalerupobfsctd-2f2786@troppus with the products and quantities you're interested in, and we'll respond with custom pricing tailored to your needs.

For first-time customers and large orders, we occasionally run a brief verification step to protect against fraud. This is rare and usually resolves within a few hours during business hours. If your order is being reviewed, you'll receive an email from our team — and you're welcome to email us directly to expedite the process.

Not at this time. We ship exclusively within the United States, including Alaska, Hawaii, and APO/FPO addresses. We're 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'll receive an email with tracking the moment your label is generated.

Transit time depends on the method you select at checkout:

• USPS Priority Mail — 2 to 3 business days
• FedEx 2Day — 2 business days
• FedEx Standard Overnight — next business day

Note on weekend timing: shipping methods count business days only, so Friday overnight orders are delivered the following Monday — not Saturday. If you need a guaranteed weekend delivery, contact us before placing your order and we'll see what we can arrange.

Delivery dates are estimates provided by the carrier and can be affected by weather, holidays, and peak periods.

Free USPS Priority shipping on all orders $200 and over — no code needed, the discount applies automatically at checkout. For orders under that threshold or for expedited methods, exact rates are calculated at checkout based on weight and destination. Typical rates:

Yes. Every shipment goes out in plain, unbranded packaging with a generic return address. Nothing on the exterior of the box indicates the contents, our company name, or the nature of what's inside. What you ordered stays between you and us.

Standard shipments do not require a signature. If you'd like signature-required delivery for added security — common for high-value orders or buildings without a secure delivery point — select a "Signature Required" FedEx option at checkout, or mention it in your order notes and we'll add it.

Our peptides are shipped lyophilized (freeze-dried) and are stable at ambient temperatures for the duration of normal transit. Cold packs aren't standard, but if you're shipping to a region experiencing extreme heat, we recommend selecting FedEx Standard Overnight at checkout to minimize transit time.

USPS Priority Mail includes up to $100 of insurance by default. FedEx services include declared-value coverage that scales with the shipment value. If your order arrives damaged or doesn't arrive at all, we'll work with the carrier on a claim and replace or refund your order — see our Shipping & Returns page for the full process.

You'll automatically receive an email with your tracking number the moment your shipping label is generated. If you have an account, the same tracking number is also visible in your order history at any time.

Probably not. USPS in particular sometimes goes silent for a day or two between scans, especially during peak periods or after pickup but before the package reaches a sorting facility. Give it 48 hours. If there's still no movement after 5+ business days, email us with your order number and we'll investigate with the carrier.

If your order hasn't yet been packed, yes — email us immediately and we can usually update the destination. Once a shipping label has been generated, the carrier (not us) controls re-routing. You may be able to redirect the package using USPS Hold Mail or FedEx Delivery Manager with your tracking number.

First, check with neighbors, building managers, or your local post office / FedEx hub — packages are occasionally scanned early or left in unexpected spots. If it still doesn't surface within 48 hours, contact us with your order number and tracking. We'll open a carrier investigation and work toward a replacement or refund based on the findings.

Packages returned as undeliverable, refused, or for an incorrect address will be refunded for the product cost only. Original shipping is non-refundable, and a 10% restocking fee may apply to cover inspection before any product can be reissued. To minimize the chance of this happening, double-check your shipping address at checkout.

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. By placing an order, you confirm you are a qualified researcher purchasing these materials solely for legitimate research.

Our peptides are typically ≥99% purity, confirmed through HPLC and mass spectrometry analysis as part of our standard quality control. Specific purity values for each batch are available on individual product pages and on the Certificate of Analysis (COA) we can provide on request.

Yes. COAs are available for every product we ship. If a current COA isn't visible on the product page, email moc.seditpepbalerupobfsctd-748f2b@troppus with the product name and we'll send the most recent batch documentation.

Storage conditions vary by compound. As a general rule:

• Lyophilized (unreconstituted) peptides — store sealed at -20°C for long-term, or 2-8°C for short-term use
• Reconstituted peptides — store at 2-8°C and use within the timeframe specified by the compound (typically 7-30 days)
• Avoid repeated freeze-thaw cycles, which can degrade peptide integrity

Refer to the product page or COA for compound-specific guidance, and check our PeptideDosages.com reference site for detailed protocols.

All our peptides ship lyophilized (freeze-dried) as a stable powder. This format gives the longest shelf life, simplifies shipping (no cold-chain required for transit), and lets you reconstitute to the exact concentration your research calls for using bacteriostatic water or another appropriate diluent.

Probably not. Lyophilized peptides can show minor cosmetic variation between batches — small differences in cake structure, color shade, or particulate consistent with specifications are normal and not defects. As long as the COA confirms the batch meets purity specs, the product is performing as expected. If you have specific concerns, send us a photo and your batch number and we'll review it.

"Research Use Only" means our products are intended strictly for in-vitro laboratory research and development. They are not drugs, dietary supplements, cosmetics, or medical devices, and they are not intended to diagnose, treat, cure, or prevent any disease. They are not sterilized, not pharmaceutical-grade, and not intended for any in vivo use, diagnostic testing, or therapeutic application.

We sell to U.S. business and institutional customers only — laboratories, universities, contract research organizations (CROs), biotechnology companies, and similar professional entities. Buyers must be at least 21 years old and authorized to purchase on behalf of their organization. We do not sell to individual consumers. See our Terms & Conditions for full eligibility details.

For most orders, no — placing an order constitutes your representation that you meet our buyer eligibility criteria. For larger orders, wholesale accounts, or if our compliance review flags an order for verification, we may request supporting documentation such as an EIN, institutional email, business website, or professional license. This is a standard practice in the research-materials industry.

Resale to other research entities under our standard wholesale terms is permitted with prior approval. Resale or distribution to consumers, residential addresses, or for clinical/therapeutic use is strictly prohibited and constitutes a material breach of our Terms. Contact us if you'd like to discuss a wholesale relationship.

We accept returns on products that are fully intact and in their original, unopened packaging. If the seal is unbroken and the product hasn't been used or stored outside our recommended conditions, you're welcome to return it for a refund or store credit.

To start a return, email moc.seditpepbalerupobfsctd-64c2dd@troppus with your order number and a brief explanation. We'll send return instructions and confirm the next steps. Return shipping is the buyer's responsibility unless the return is due to our error.

If your order arrives damaged, incorrect, or missing items, that's a separate process — see the next questions for how we handle those issues at no cost to you.

Email us within 72 hours of delivery with the following:

• Your order number
• Photos of the shipping box, packing materials, and any damaged vials
• A brief description of what's wrong

Send everything to moc.seditpepbalerupobfsctd-17bfbe@troppus. Most claims are resolved within one business day, and we'll arrange a replacement, credit, or refund — your choice. No return shipping required for damaged goods.

Same process — email us within 72 hours of delivery with your order number, a photo of what you received, and a brief description. We'll send the correct item and provide a return label for the incorrect one if needed.

Email us within 72 hours with your order number and a brief description of what's missing. If possible, include a photo of the box and its contents as you received them. We'll verify against the original packing list and ship the missing item as quickly as possible.

Carrier insurance windows for damage and loss claims expire quickly — typically within a week. The faster we know about an issue, the easier it is to file a successful claim and get you a replacement. Claims received after 72 hours may not be eligible for replacement or refund.

Yes. Our checkout is protected by 256-bit SSL encryption, the same standard used by major financial institutions. Your personal and payment details are encrypted in transit and never visible to anyone outside the systems required to process your order. Sensitive transactions are routed through secure pages to prevent unauthorized access.

We do not sell, rent, or loan your personal information to third parties. The only parties who receive any portion of your data are the shipping carrier (for delivery) and our payment processor (for transaction settlement) — both of whom are bound by their own privacy obligations. We do not engage with third-party ad networks or content delivery services that compromise privacy. See our Privacy Policy for full details.

Yes, anytime. Every marketing email includes an unsubscribe link at the bottom — one click and you're off the list. Transactional emails (order confirmations, shipping notifications) can't be unsubscribed from while you have active orders, but you'll only receive them when something is happening with your shipment.

Email moc.seditpepbalerupobfsctd-4f0bad@troppus from the email address associated with your account. We'll verify your identity and process the request within a reasonable timeframe. Note: we may retain order records for the period required by law (typically 7 years for tax and compliance purposes), but personal contact information can be removed upon request.
