Two ways to get your sample to the lab. Self-ship directly for the fastest start, or use a kit with a prepaid label. Both work.
Ship directly to the lab using your own packaging — the fastest way to get your sample tested, with no kit to wait for. Cheaper on shipping costs if you already have what you need. Best for vendors and repeat submitters.
Vendors: email labs@checkpeptide.com to arrange direct submission without a checkout order.
Order Self-Ship →A more guided option if you'd rather not source your own packaging. We ship you a kit with everything you need: collection vials, a sample form, and a prepaid return label. Adds 1–2 days before your sample even reaches the lab.
Kit ships within 1–2 business days of your order. Turnaround starts from when the lab receives your sample.

Proper packaging protects the integrity of your sample and prevents delays at the lab.
Wrap each vial in bubble wrap or foam padding. Place in a rigid outer container — a small cardboard box works well. Do not ship loose in a padded envelope.
Keep refrigerated until shipping. Ship with an ice pack if possible for multi-day transit.
Write your CheckPeptide order ID on the outside of the package and on a slip inside. If you're submitting multiple samples, label each vial separately with the compound name and your order ID.
Send only what's needed. Most panels require 0.5–2mg of compound. Sending more doesn't improve results and adds cost. Kit customers: follow the quantities specified in your kit instructions.
Ethos Analytics logs your sample on arrival. You'll receive a confirmation email when the lab accepts your submission. Turnaround starts from this point.
Your sample is processed according to the panel you ordered. Results are reviewed by laboratory staff before being issued. No automated results — every COA is signed off by the lab.
Your Certificate of Analysis is emailed with your permanent COA ID. The result is simultaneously published to the public lookup database at checkpeptide.com/verify.
