Section 02

Discreet & secure packaging

Plain, unmarked packaging — always
All orders ship in plain, unmarked packaging to protect the privacy and security of your research materials. There are no mentions of peptides, research chemicals, or RNXResearch on the external mailing label. The return address and shipping label are neutral and non-descriptive. Your privacy is our default — not an option.

All products are packaged in sealed glass vials, wrapped securely to prevent damage or breakage in transit, and placed inside protective packaging appropriate for fragile laboratory materials.

Section 03

Domestic shipping only

We currently ship exclusively via USPS to addresses within the United States. This includes:

  • All 50 US states and US territories
  • P.O. Box addresses
  • APO and FPO military addresses

Typical transit times range from 2–5 business days depending on your location. Transit times are estimates provided by USPS and are not guaranteed. RNXResearch is not responsible for carrier delays outside our control.

International shipping is not currently offered through standard checkout. If you are located outside the United States and wish to place an order, contact us directly at support@rnxresearch.com and we’ll evaluate your request on a case-by-case basis.

Section 04

Shipping issues & missing packages

We ship every order carefully and with full tracking. However, once a package is in the hands of USPS, certain outcomes are outside our control.

  • Delayed packagesCheck your tracking link for the most up-to-date status. USPS tracking occasionally shows delays before updating — allow 24–48 hours before contacting us.
  • Damaged packagesIf your package arrives damaged, contact us within 72 hours of delivery at support@rnxresearch.com with photos of the packaging and contents. Reports submitted after this window will not be eligible for review.
  • Incorrect addressYou are responsible for ensuring your shipping address is correct at checkout. RNXResearch is not responsible for packages shipped to an incorrect address provided by the customer. Contact us immediately if you notice an error — if the order has not yet shipped we can correct it.
Section 05

Official delivery policy

Official delivery policy — GPS confirmed delivery

RNXResearch relies on the GPS-tracked delivery confirmation provided by USPS. Once a package is scanned as Delivered to the address provided at checkout, it is considered fulfilled. We cannot be held liable for packages that are stolen from a porch or mailbox after a successful delivery scan.

We do not provide refunds or replacements for any package with a confirmed delivery status from USPS. If your package is marked as Delivered but you have not received it:

  • Wait 24 hours — carriers occasionally scan packages as delivered before the final drop
  • Check with neighbors and any other household members who may have accepted the package
  • File a missing mail claim directly with USPS at usps.com/help/missing-mail
  • File a police report if you believe the package was stolen — this is required for any carrier insurance claim

We strongly recommend shipping to a secure location or laboratory facility where a recipient is available to accept delivery.
