EJ disposable pens

An EJ disposable pen is a prefilled peptide pen sold as a single sealed unit, with the material sealed inside the pen body.

Each listing names the product and its strength and shows its price. Blends list the amount of each component.

Lab reports open without an account. A report is linked to a product only when the name and strength match. For laboratory research only.
