Orders ship after payment clears and passes verification. Zelle, Venmo, and Cash App payment requests are typically sent within ~30 minutes between 9:00 AM–12:00 AM (midnight) EST. If you order outside those hours, you will receive the request the next day. Check and money order orders remain on hold until deposited funds clear.

We fulfill from U.S. warehouses in Florida, North Carolina, and California. Same-day processing applies to orders placed before 3:30 PM Eastern (Mon–Sat) after payment clears. Shipping options and rates depend on whether your cart is vial-only or includes box items — see Shipping & Delivery Policy for carriers and current rates.

Tracking numbers are emailed when your order ships. Use the AfterShip tracker in the site header, or visit the Orders & Tracking page for step-by-step guidance.

COAs are provided by our manufacturing vendors and/or their contracted testing laboratories — Nextday Peptides does not independently test each lot in-house. Availability varies by product and lot; contact orders@nextdaypeptides.com if you need help locating a specific batch.
