Everything you need to know about ordering, payments, and our products.
We accept manual payments via Zelle, Venmo, and Cash App. After placing your order, you'll receive payment instructions by email. We currently do not process credit cards directly to keep our prices low and protect customer privacy.
After checkout, you'll receive an email with our payment handles for Zelle, Venmo, or Cash App. Send the exact total to one of the provided handles, then reply with a screenshot of your payment confirmation. Once verified, your order is processed and shipped.
The payment handles for Zelle, Venmo, and Cash App are included in your order confirmation email. Please use only the handles listed there — we will never request payment through any other channel or app.
Please include your order number in the payment note (for example: "Order #12345"). This helps us match your payment to your order quickly. Avoid using product names or anything that describes the contents of your order.
Reply directly to your order confirmation email with the screenshot attached, or send it to cs@structurabio.com with your order number in the subject line.
Verification usually takes 1–4 business hours during regular hours (Mon–Fri, 9am–6pm EST). Payments sent over the weekend are typically verified the next business day.
No problem — just send it as soon as you remember. Your order will remain on hold until we receive and verify your payment. If we don't hear from you within 48 hours, the order is automatically cancelled and can be re-placed at any time.
Currently we only accept manual payments via Zelle, Venmo, and Cash App. This allows us to keep prices low and avoid the higher fees associated with credit card processing. We may add additional payment options in the future.
Once your payment is verified, orders are shipped within 24–48 hours. U.S. domestic delivery typically takes 2–3 business days via cold-chain shipping. You'll receive a tracking number by email as soon as your package leaves our facility.
A tracking number is sent to your registered email as soon as your order ships. You can also log in to your account on our website and view tracking information under "My Orders."
At this time we ship within the United States only. We're working on expanding international shipping options — please subscribe to our newsletter to be notified when this becomes available in your region.
If your package arrives damaged or any vials look compromised, please email us at cs@structurabio.com within 48 hours of delivery with photos of the package and the affected items. We'll arrange a replacement or refund right away.
