Our Verification Process
How Every Batch Is Verified
We do not take a manufacturer's word for it. Every batch goes through the same four steps before it reaches you.
01
Synthesis
Compounds are produced with pharmaceutical-grade raw materials and controlled synthesis for batch-to-batch consistency.
02
Purity Testing
Each batch is screened by HPLC and confirmed by mass spec. Anything under our purity bar does not get listed.
03
Independent Third-Party COA
Verified by independent USA labs (Chromate Labs and BT Labs) so there is no conflict of interest in our numbers. We also publish endotoxin data.
04
Ships With Documentation
The batch-specific COA is on the product page before you buy and travels with your order.

Frequently Asked Questions
Find quick answers to the most common inquiries about our chemical supply services.
What purity standard do your peptides meet?
Every compound is tested to high purity by HPLC and confirmed by mass spectrometry. Batches that do not clear our bar are not listed.
Are your products third-party tested?
Yes. We do not rely on manufacturer documents. Every batch is independently verified by US labs (Chromate Labs and BT Labs), and the COA is on the product page.
What is a COA and where do I find it?
A Certificate of Analysis is the lab report for that specific batch. It is linked on every product page and ships with your order.
How do I order and how do I pay?
Add your compounds to cart and check out through our secure portal. Orders can be placed any time.
Why do I need a peptide in my cart to buy BAC water?
BAC water is a research essential meant to pair with a peptide order. To keep things simple it is available alongside a peptide rather than on its own.
How fast do you ship and where?
Orders confirmed before 2PM EST ship the same day, in discreet packaging. We ship within the United States. Tracking is emailed once your order is on its way.
How should I store peptides?
Store lyophilized peptides cold and dark. Once reconstituted, keep refrigerated and use within the recommended window. See our Storage & Handling Guide for full detail.
What is your return policy?
Because these are research compounds, all sales are final. If something arrives damaged, incorrect, or mislabeled due to our error, contact us within 48 hours and we will make it right.
