Pick your compounds and check out securely by card over an encrypted connection.
Your vials are pulled from a batch assayed by HPLC and mass spectrometry, with the COA on file and independently verifiable on request.
Plain, unmarked packaging with tracking, dispatched the next business day anywhere in the US.
Match the batch number printed on your vial to its certificate of analysis online, any time.
Every batch, independently verifiable
We do not ask you to take purity on faith. Every lot is assayed by HPLC and mass spectrometry and released with a certificate of analysis matched to the batch number printed on your vial. Independent third-party verification of any lot is available on request.
- 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.
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.
Ordered Tuesday afternoon, plain unmarked box at the lab Thursday morning. Tracked the whole way, nothing on the package but the shipping label.
Emailed about an older batch certificate and support sent the full PDF within the hour, then followed up after delivery. Fast, human service.
Every vial arrived perfectly packed, caps intact, batch numbers printed cleanly and matching the paperwork. The best packaging quality we have seen from a US supplier.
Third-party test results are posted before you order, not after you ask. That level of transparency is why our lab keeps reordering.
Card payment cleared within minutes and the order went out the same day. Two orders in, both flawless, both with certificates on file.
Reviews are moderated and may only describe product quality, documentation, shipping and service. All products are for in-vitro research use only.
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 next business day 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. You can look up any lot by its batch number.
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.
Do these come ready to use, or do I need to reconstitute them?
The peptides are supplied lyophilized (freeze-dried) for stability, so they are reconstituted with bacteriostatic water in a laboratory setting for in-vitro research. Our free reconstitution calculator works out the concentration and syringe draw for any vial size, and bacteriostatic water is stocked in our reconstitution supplies.
How should I store my compounds once they arrive?
They ship lyophilized (freeze-dried), which is stable in transit and tolerates brief time at room temperature. Keep the sealed vial refrigerated for short-term storage or frozen near minus 20 C for longer, and once reconstituted keep the vial refrigerated and use it within its stability window. Our storage guide covers shelf life before and after reconstitution in detail.
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, 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 my package is held or seized?
Because we ship domestically, packages do not clear 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 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.
