processed within 1\u20132 business days after payment is confirmed. The fulfillment cutoff is 3:00 p.m. Eastern time, Monday through Saturday. Orders confirmed after the cutoff, on Sundays, or on postal holidays are treated as received the next business day.<\/p><\/div><\/details>\n  <details><summary>What does shipping cost, and where do you ship?<\/summary><div class=\"pp-faq-answer\"><p>Panda currently ships within the United States only. USPS Priority Mail is $10 flat rate and free on orders of $50 or more. After dispatch, USPS Priority Mail typically arrives in 1\u20133 business days. See the <a href=\"\/shipping-policy\/\">Shipping Policy<\/a>.<\/p><\/div><\/details>\n  <details><summary>Will I receive tracking?<\/summary><div class=\"pp-faq-answer\"><p>Yes. Tracking is emailed after the order ships. You can follow it through Panda or directly on the carrier\u2019s website. A label-created scan means the carrier has the shipment information; movement may not appear until the carrier performs its first physical scan.<\/p><\/div><\/details>\n  <details><summary>What payment methods are available?<\/summary><div class=\"pp-faq-answer\"><p>The live checkout shows the currently available options, which may include Cash App (LN), Zelle, bank transfer, and credit card. Card statements may show the processor or merchant descriptor instead of Panda Peptides.<\/p><\/div><\/details>\n<\/div><\/section>\n\n<section class=\"pp-faq-section\"><h2>Order help after checkout<\/h2><p class=\"pp-section-intro\">The quickest resolution depends on whether the issue happened before shipment, during carrier transit, or inside fulfillment. These answers tell you what to check and what evidence helps.<\/p><div class=\"pp-faq-grid\">\n  <details open><summary>I entered the wrong shipping address. What should I do?<\/summary><div class=\"pp-faq-answer\"><p>Contact <a href=\"mailto:support@pandapeptides.com\">support@pandapeptides.com<\/a> immediately with your order number and the complete corrected address. We can change it only before the order ships. Once a parcel has shipped, a carrier redirect may not be available, and Panda is not responsible for delivery to an incorrect address supplied at checkout. See the <a href=\"\/shipping-policy\/\">Shipping Policy<\/a>.<\/p><\/div><\/details>\n  <details><summary>I did not receive an order or tracking email. What should I check?<\/summary><div class=\"pp-faq-answer\"><p>Check spam, junk, and promotions folders, then confirm the email address entered at checkout. An order confirmation and a shipping email are separate: tracking is sent only after dispatch, and processing begins after payment is confirmed. If the message is still missing, contact support with the name and email used for the order so we can verify its status.<\/p><\/div><\/details>\n  <details><summary>Tracking is delayed or has stopped moving. When should I contact Panda?<\/summary><div class=\"pp-faq-answer\"><p>Carrier scans can be delayed or skipped. Continue monitoring the carrier record, including any updated delivery estimate. If tracking shows no movement for 10 business days, or the carrier confirms the parcel is lost sooner, contact support with your order number. We will verify the shipment and handle an eligible loss under our <a href=\"\/return-policy\/\">Return Policy<\/a>.<\/p><\/div><\/details>\n  <details><summary>Tracking says delivered, but I cannot find the package. What should I do?<\/summary><div class=\"pp-faq-answer\"><p>First check the mailbox or parcel area, entrances, household members, neighbors, building office, and mailroom. Confirm the shipping address on the order, then contact the local carrier office because GPS or delivery-scan details may help locate it. If it remains missing, email support within 30 days with your order number, confirmed address, and the checks already completed. A delivered scan is reviewed differently from a carrier-confirmed loss, so the available resolution depends on the evidence and our policies.<\/p><\/div><\/details>\n  <details><summary>My package arrived damaged. What should I send?<\/summary><div class=\"pp-faq-answer\"><p>Keep the parcel, packaging, and affected products. As soon as possible\u2014and within 30 days of the carrier\u2019s delivery timestamp\u2014email support with your order number and clear photos of the shipping label, outer packaging, inner packaging, all contents, and each damaged vial or product label. Do not discard the evidence before our review.<\/p><\/div><\/details>\n  <details><summary>An item is missing or incorrect. How is that handled?<\/summary><div class=\"pp-faq-answer\"><p>Photograph the shipping label, the opened package, all contents together, and the label of any incorrect item. Email the photos and order number to support within 30 days. We compare the report with our packing records and review it as a fulfillment issue\u2014not as a carrier-loss claim\u2014under our <a href=\"\/return-policy\/\">Return Policy<\/a>.<\/p><\/div><\/details>\n<\/div><\/section>\n\n<aside class=\"pp-help-strip\" aria-labelledby=\"pp-help-title\"><div><span class=\"pp-help-kicker\">Fastest path to review<\/span><h2 id=\"pp-help-title\">Send the useful evidence once<\/h2><p>One complete message helps us identify the cause without making you repeat the story.<\/p><\/div><ol class=\"pp-help-list\"><li>Your order number and a short description<\/li><li>A clear photo of the shipping label<\/li><li>Outer package, inner package, and all contents<\/li><li>Close-ups of any damage or incorrect product label<\/li><\/ol><\/aside>\n\n<section class=\"pp-faq-section\"><h2>Product appearance and transit<\/h2><p class=\"pp-section-intro\">Appearance can be useful evidence, but it does not replace the analytical results shown on a batch report.<\/p><div class=\"pp-faq-grid\">\n  <details open><summary>Why is the material a dry cake or powder instead of a liquid?<\/summary><div class=\"pp-faq-answer\"><p>Most Panda peptide products are supplied in a lyophilized (freeze-dried) state, so the material may appear as a dry cake, powder, or thin residue inside the vial. That is the expected physical form for these research materials; they are not shipped as prepared solutions.<\/p><\/div><\/details>\n  <details><summary>Does a cracked or shifted dry cake mean the product is damaged?<\/summary><div class=\"pp-faq-answer\"><p>Lyophilized material can shift or fragment during transit. A broken or uneven cake by itself does not establish the product\u2019s identity, purity, or measured content. Inspect the vial and seal instead: if the glass is cracked, the stopper or seal is displaced, moisture or leakage is visible, or anything else appears compromised, set the vial aside and send clear photos to support.<\/p><\/div><\/details>\n  <details><summary>Should I be concerned about temperature during shipping?<\/summary><div class=\"pp-faq-answer\"><p>Lyophilization removes moisture and generally improves stability compared with the same material in solution, but stability remains compound-, temperature-, and time-specific. Panda does not make a blanket claim that every product tolerates every temperature or transit delay. Routine ambient transit alone is not evidence that a vial failed its stated batch specification; contact support if the parcel had an extreme delay, physical damage, moisture, or a compromised seal.<\/p><\/div><\/details>\n  <details><summary>Can visible material tell me the vial\u2019s purity or amount?<\/summary><div class=\"pp-faq-answer\"><p>No. Visual appearance cannot establish identity, purity, or measured content. Use the product\u2019s batch number and the linked independent report to see exactly which tests were performed and what the laboratory reported.<\/p><\/div><\/details>\n<\/div><\/section>\n\n<section class=\"pp-faq-section\"><h2>How Panda separates order problems<\/h2><p class=\"pp-section-intro\">We classify the cause before choosing a resolution.
