Are your products for human use?

No. All products are sold strictly for laboratory research use. They are not for human or veterinary consumption.

How fast do you ship?

Orders placed before 3PM ship the same or next day via express 2-day air. Typical delivery is 2–4 business days once shipped (domestic). Tracking is sent as soon as your order leaves the facility — see Track Order.

Where are your products made and tested?

Everything is manufactured in a cGMP-compliant facility in Shenzhen, China, then independently tested lot by lot — at our partner laboratory (ISO/IEC 17025:2017 accredited). See how we test.

How do I find the lab report for my vial?

Scan the QR code on the vial label, or search the lot number on the lab's report hub. Product reports are also in our COA library.

Do you offer bulk pricing?

Yes — buy 3–5 vials and save 5%, or 6+ and save 10%, on most peptides. The discount applies automatically in your cart. Bacteriostatic water and add-ons are excluded from all discounts.
