The CoA matched what I independently verified in my own assay. That's not something I've been able to say about most suppliers.

The Woosh Guarantee
Each batch is independently verified and documented—so you know exactly what you're working with.
Every batch is tested by an accredited, independent laboratory before it ever ships. The report is signed, dated, and attached to your order so you can verify identity and purity against your own protocols.
A batch-specific Certificate of Analysis accompanies every shipment — HPLC purity, mass spec identity, and residual solvents. No generic PDFs, no skipping batches.
Orders are packaged under cold-chain conditions where required, tracked end-to-end, and automatically replaced if lost, damaged, or delayed in transit. No upsell, no claim paperwork.
Compounds that fail our ≥99% HPLC purity standard do not reach the catalogue. If a batch narrowly misses after retesting, it is destroyed rather than down-labelled.

Don't take our word for it.
Johanna M.
— Protocol researcher
Compound arrived lyophilized, correctly labeled, with a batch-specific CoA. Exactly what a research order should look like.

I switched to Woosh after a competitor's purity claim didn't hold up to third-party testing. Haven't had that issue since.

The research library is genuinely useful. Study citations, mechanism breakdowns — not just marketing copy dressed up as science.

Every batch is independently tested via third-party HPLC and mass spec. The full Certificate of Analysis is published before purchase, verifying >99% purity.
A CoA documents the exact compound tested, its purity, and batch identifiers. It's the only independent proof that what's in the vial matches what's on the label.
These are research-grade compounds intended for laboratory study only. Not for human or veterinary use. All research protocols should follow your institution's guidelines.
Store lyophilized peptides at –20°C. Once reconstituted, keep at 2–8°C and use within 30 days for maximum stability.
