Verified potency
RP-HPLC quantifies active peptide content against a reference standard on every lot — the contents match the label, down to the microgram. No estimates. No guesswork.
HPLC
Documented purity
High-performance liquid chromatography establishes purity on each batch, and the result is printed on the lot's Certificate of Analysis — not just claimed on the label.
LC-MS
Confirmed identity
Mass spectrometry confirms the molecular identity of every compound, so the sequence you ordered is the sequence in the vial.

What the research community says
Lot-to-lot consistency is what kept us here. The published COAs line up with the HPLC traces we run in-house, so repeating an earlier experiment on a new lot is actually predictable.
Principal Investigator R1 Research University
PI-MOLBIO-01 The Certificate of Analysis shows what I actually need to see — mass spec for identity, HPLC for purity, endotoxin screening. That’s documentation, not a sticker.
Laboratory Director Independent Research Laboratory
LAB-DIR-02 Batch-specific COAs and clean paperwork make our internal review simple. Every lot maps back to a record we can file and audit.
Preclinical Program Manager Contract Research Organization
CRO-PRE-03 We moved over after purity problems with a previous supplier. The HPLC numbers here have held up against our own analysis, lot after lot.
Research Scientist State University Medical Center
MED-CTR-04 The price-to-quality ratio is hard to argue with, and bundle discounts make larger orders workable on a study budget without giving up documentation.
Senior Scientist Private Research Institute
PRI-SCI-05 Packaging was professional and secure, vials arrived intact, and the lot documentation matched the order exactly — carrier tracking from dispatch to delivery.

Frequently asked questions
Clear, professional communication focused on documentation, order fulfillment, transparency, and research-use compliance.
Contact supportAre Reflex Peptides products intended for human use?
No. All Reflex Peptides products are supplied exclusively for laboratory research purposes. They are not intended for human or veterinary use, nor for the diagnosis, treatment, cure, or prevention of any disease.
Do your products include a Certificate of Analysis (COA)?
Yes. Every batch is analyzed by an independent U.S. laboratory and its Certificate of Analysis is published in our COA Library, linked from each product page.
How is product quality verified?
Each batch undergoes independent HPLC and mass-spectrometry testing to confirm identity, purity, and consistency before release.
When will my order be shipped?
Orders are processed promptly and shipped with tracking. Free US shipping applies to orders over $100; Priority shipping is $8.95 otherwise.
How can I contact customer support?
Through the contact page or by email. We maintain clear, professional communication focused on documentation, order fulfillment, and research-use compliance.
