Your Questions

Everything you
need to know

The questions our customers actually ask, answered straight.

01Is it tested? How do I know what is in the pen?

Every batch is blind tested by Janoshik Analytical, an independent third-party laboratory, at 99.7% purity by HPLC. You can verify the certificate yourself on their site with the unique key printed on it.

02Does it need reconstitution?

No loose vials, no measuring. The lyophilised powder and the diluent are sealed in separate chambers. One twist combines them, and the dial is calibrated in fixed increments for precise laboratory measurement.

03What is in the box?

One sealed 30 mg dual-chamber pen and the batch certificate of analysis for the lot you receive.

04How does delivery work?

Ships from the USA via DHL Express, tracked to your door. 3 to 5 working days in the US, 5 to 7 working days to Australia, Canada, the UK and Ireland. Tracking lands in your inbox the moment it ships.

05How do I pay?

Straight through secure card checkout — pay by card in under a minute, and your order ships the moment payment is confirmed. You get a receipt instantly, and our support team is one email away if you need anything.

06How should it be stored?

Keep refrigerated at 2 to 8°C. The powder stays dry and sealed apart from the diluent until activation.
