Independent laboratories
We do not test our own products. Identity and purity are confirmed by independent third-party analytical laboratories — we use more than one, and we publish their reports as issued.
~99% HPLC purity — shipped from Washington
Research compounds you can verify.
Every batch we sell is tested by independent third-party laboratories for identity, purity, net content & endotoxins. Those certificates for every batch are published on the product page — current and past COAs alike.

How we verify what we sell
We do not test our own products. Testing is done by outside laboratories, and the reports are published exactly as issued.
Purity and endotoxin
Reports cover identity, purity by HPLC, and net content, confirmed by mass spectrometry. Most batches also carry a separate endotoxin certificate.
Nothing gets taken down
When a new batch replaces an old one, the previous certificate stays published. The full testing history of a product remains visible on its page.
Tied to a batch, not a product
A certificate belongs to one specific batch. Every COA on our site is labeled with its batch number, vial size, and test date so you can match it to what you received.
Why we started
NicePeps Staging is a chemical supplier based in Washington. We started https://staging.nicepeps.com because sourcing research compounds was harder than it needed to be — purity figures with nothing behind them, certificates that could not be traced back to a specific batch, and suppliers who went quiet once the order shipped.
We took the opposite approach. Every product is tested by an independent laboratory before it is offered, every certificate is published on the product page with its batch number and test date, and older reports stay up when new batches replace them. If you want to check our work before you order, you can.
