The tall peak is the compound itself. The small rises are everything else in the vial — that difference is what purity measures.
Why trust us
Science they can’t silence.
The thing most suppliers keep quiet is the data. Anyone can print “99% pure” on a label. We send every batch to an independent laboratory and publish the actual results — the exact purity figure, which lab ran it, and the date. And if a number ever comes back lower than we’d like, you’ll still see it. That’s the whole point. A number you can’t check isn’t a number — it’s a marketing claim.
Common questions
Before you order
Pack pricing comes first — 5% off at 5 items, 10% at 10, 20% at 20 or more, applied automatically. Your 40% first-order code applies on top of that at checkout. Paying with Bank Pay then takes a further 10% off. During an automatic sale such as the BOGO, checkout applies whichever offer saves you more.
Enter your email anywhere on the site and we send the code straight away, along with the Peptide 101 Playbook. Apply it at checkout on your first order — a vial of bacteriostatic water is added free at the same time.
Yes. Peptides ship as a freeze-dried powder and require bacteriostatic water to reconstitute. A 10ml vial covers several compounds and is free with your first order. If your cart doesn't have one, we flag it at checkout.
Within 24 hours, from our own inventory in Florida and California. Standard delivery is 2–4 business days and free over $150. We hold physical stock rather than drop-shipping.
File a claim from your account and we review it within one business day. Broken seals, missing vials and packages that never arrive are replaced.
Here. Every compound Real Peptides sells is tested by an independent laboratory — Freedom Diagnostics or Kovera — and the certificate of analysis for the batch is published on the product page and at /coas before you order. Stock is held in Florida and California and ships within 24 hours. Everything is sold for laboratory research use only.
The peptides on this site are supplied to researchers and laboratories as reference materials. They are not drugs, dietary supplements or cosmetics, are not intended for human or animal use, and nothing on the site is medical or dosing advice. Buyers confirm they are 21 or older and are purchasing for research.
Each production batch is sent to a third-party laboratory for HPLC purity and, where applicable, endotoxin and sterility testing. The report carries the batch's lot number, the lab that ran it and the test date, and it stays on file even after that batch sells out — search any lot number at /coas.
