What they are

Pre-mixed pens, ready to supply

A peptide pen is a pre-filled cartridge of reconstituted research peptide in a refillable pen device — removing the reconstitution and measuring step that raw vials require. For brands and clinics, that means a cleaner, more consistent product to put in front of customers.

What's included in a complete pen package?

A refillable pen device, a pre-filled peptide cartridge, pen needles and a case — supplied ready to brand and retail. Refill cartridges are also available separately for customers who already own a pen.

Yes. Pre-filled refill cartridges are available on their own, which is the cost-efficient format for reorders and subscription-style lines where customers already have a pen.

Do wholesale pens come with a COA?

Yes. Every batch is independently HPLC-tested and ships with a Certificate of Analysis. Cartridges are batch-labelled with lot numbers for full traceability. See how testing works.

Can I get peptide pens white labelled?

Yes. We produce pens and packaging under your branding from 1,000 units per SKU, with finished stock ready in 14–21 business days from approved artwork. See white label solutions.
