Product & documentation questions

How do I read the size and pack quantity?

The per-vial size and number of vials per pack are listed separately in the table. The displayed price is for one pack. A blend’s stated size can describe combined ingredients; check its product label and report for individual components.

How do I find the matching COA?

Match the product, SKU and batch number with the published report. Open the batch page to read the actual results, original report and laboratory verification link. Ask support to confirm the allocated batch if it is not on your order.

Does a purity result mean every test passed?

No. Identity, purity, fill and endotoxin are separate measurements. Read each reported result and unit. An absent result is not a pass, and a less-than result is not zero.

Research Information

Semax is investigated for its effects on the expression of BDNF and NGF, dopaminergic and serotonergic signaling, and neuroprotection under ischemic and oxidative-stress conditions in animal and cell models of cognition and brain injury. Supplied strictly for in-vitro and laboratory research use only — not for human or animal consumption.
