Frequently asked questions
What is a pre-filled peptide pen?
A research format that arrives with the compound, strength and batch clearly labelled on the pen itself.
How is a pen different from a vial?
A vial typically supplies the compound as a powder. An Apexion pen arrives pre-filled and labelled with the compound, strength and batch.
When is each pen made?
After you order, under controlled clean conditions. Every pen carries its manufacturing date.
Are the pens tested?
Yes. Each batch is supported by HPLC purity testing and independent third-party analysis, and a Certificate of Analysis is available with your order.
How should a pen be stored?
Each product page lists guidance for that compound. In general, keep pens in cool, stable conditions away from direct light.
