The process

How it works

From order to verified certificate in four steps.

01
Place your order

Pick your compounds and check out securely by card, processed by Stripe.

02
Lab-tested batch

Your vials are pulled from a batch assayed by HPLC and mass spectrometry, with the COA on file and independently verifiable on request.

03
Discreet tracked shipping

Plain, unmarked packaging with tracking, dispatched the same week anywhere in the US.

04
Verify your COA

Match the batch number printed on your vial to its certificate of analysis online, any time.

Every batch, independently tested

We do not ask you to take purity on faith. Every lot is third-party assayed by HPLC and mass spectrometry, and the certificate of analysis is matched to the batch number printed on your vial.

  • RP-HPLC-UV purity plus LC-MS identity on every lot
  • Certificate matched to the batch number on your vial
  • Independent re-test guarantee, backed by refund

What researchers say

Real feedback on the things we control: purity documentation, packaging, delivery and support.

218 verified reviews

COA matched the batch number on my vial exactly, and our in-house HPLC run lined up with the certificate. Documentation is as rigorous as suppliers three times the price.

Frequently asked

Straight answers on testing, shipping, and payment. Anything else, email support@rttpeptides.com.

Do you ship nationwide across the United States?

Yes. Orders ship the same week from within the United States by tracked courier and arrive in 2 business days, with a cold pack for temperature-sensitive compounds.

Is testing and a COA provided?

Every lot is assayed in-house by HPLC and mass spectrometry and ships with its certificate of analysis. Independent third-party verification of any lot is available on request.

How discreet is your packaging?

Plain, unbranded, sealed packaging with nothing on the outside that names or hints at the contents.

What is the intended use of these products?

Every compound is supplied strictly as a reagent for in-vitro laboratory research. It is not for human or veterinary use.

How do I know I will receive my order after paying by card?

Every order is covered by our delivery guarantee: if it is lost, held at customs, damaged, or arrives wrong, we reship it or refund you, no dispute needed. You get a tracking number by email at dispatch, and support replies within one business day.

What happens if customs holds or seizes my package?

Domestic US shipments rarely see customs. If a package is held or seized, it is covered by the delivery guarantee and we reship or refund. We ship in plain, unmarked packaging from within the US.

What shows on my bank statement?

Nothing that names a product. Card payments are processed by Stripe and appear under a neutral trading name.

Do you provide third-party testing?

Every batch is HPLC and mass-spec tested and ships with its certificate of analysis. Independent third-party HPLC/MS verification of any lot is available on request, and our independent-test guarantee refunds your order if a vial does not match its certificate.

Can I verify a specific batch before I buy?

Yes. Each product page shows the lot currently shipping with a link to its certificate, and you can look up any batch number on the Verify COA page.
