On the record
Every purity figure is a real trace.
A reverse-phase HPLC run stands behind every batch we ship — main-peak purity, retention time, and baseline, signed on the certificate. Below is batch RR-BACWATER-260419-B.

What goes into every batch
Four tests between synthesis and the vial.
The full methodology is published on the quality page — instrument, column, gradient, detection wavelength.
Reverse-phase HPLC
Purity reported on every certificate. 220 nm detection, integrated area threshold 0.05 %.
Mass-spec identity
Accurate-mass confirmation by ESI-Q-TOF before purity is signed off.
Counter-ion + water
Karl Fischer water and ion-chromatography counter-ion content reported per batch.
Independent verification
Random batches re-tested at an external ISO 17025 lab. Report appended to the COA.

Every batch’s certificate is signed, dated, and indexed by its batch number. No account required.
Common questions
Things researchers ask first.
- Material synthesized and tested to a published HPLC purity threshold (≥ 99 % across our current catalog), suitable for use as a reference standard in in-vitro assays. Not intended for, or sold for, human or veterinary consumption.
- Every vial ships with a printed batch number. That number resolves to a specific certificate of analysis on the COA archive; the PDF lists the HPLC purity, retention time, mass-spec identity, water content, and counter-ion content for that exact run.
- Mainstream processors (Stripe, PayPal, etc.) have policies that exclude research-compound merchants. Crypto rails settle directly without periodic underwriting review. We pass the lower fees back as a 10 % discount.
- Most of the world. We block destinations where peptide imports are tightly controlled — the restricted-country list shows in real time on the shipping step of checkout.
