ShopWho tests, and what we do
How testing works
Our supplier tests every batch before it ships to us. We don’t run the tests ourselves. This page says what the supplier tells us and what we do.
Who tests
Our supplier. Testing happens before a batch ships to us.
What they test
- Purity. Our supplier reports 99% or higher, with no unwanted by-products or impurities.
- Identity and amount. They confirm the exact peptide and the full amount on each vial’s label.
- Safety screen. They check for heavy metals, endotoxins and microbes. The supplier says this keeps it safe and stable for research.
What we do
We receive the batch, record its batch number, store it and ship your order with tracking. We don’t test it again.
Test reports
When our supplier sends a report for a batch, we post it so you can search by batch number.
If something looks wrong
Tell us. We can stop selling any peptide or batch right away, including items already in carts.
What we can’t promise
The results are our supplier’s. We pass them on as they give them to us.
