How to use the dual-chamber pen
Click the cartridge in, twist until it clicks, and the pen mixes it for you.

Size
Filled at the lab. Not by us.

One 4ml cartridge holds the powder and the bacteriostatic water in two separate chambers, divided by a bypass seal. Click the cartridge into the holder, twist until it clicks, and the pen performs the reconstitution itself — then dial your dose on the ring. No vial, no syringe, no drawing up, and nothing for you to mix. The pen body is reusable; the cartridge is not.

Follow my channel — every couple of weeks I drop one genuinely useful thing: how to read a COA, reconstitution math, the odd honest deal. No spam, no hype. (I'm a capybara.)
