R - Mix On Demand Pen (20mg)

The R Mix On Demand Pen is a 20 mg dual-chamber delivery system designed for maximum flexibility and convenience. Its innovative design keeps the active ingredient and bacteriostatic water separated until you're ready to use it, allowing you to prepare a fresh solution only when needed.
 
Because the pen remains unactivated until use, refrigeration is not required prior to activation. This helps provide extended shelf life, easier storage, and greater portability—making it ideal for travel or keeping on hand until you're ready to begin your protocol.
