Reach us, quietly.

For order questions, account issues, and general correspondence, write to support@blosigen.com. Please include your order number if your message relates to a purchase.

We do not operate a telephone line. Email keeps a clear record for both parties and ensures nothing falls through the cracks.

Press enquiries, interview requests, and editorial partnerships go to press@blosigen.com. Please include your publication and intended angle.

We are willing to speak on record about sourcing, testing methodology, and the research landscape. We do not provide outcome endorsements or participate in advertorial formats.

Clinics, compounding pharmacies, and research institutions interested in volume pricing should write to wholesale@blosigen.com.

Include your entity name, jurisdiction, and a brief description of your intended use. We review wholesale applications on a case-by-case basis and maintain a short approved-supplier list.

If you have a concern about a specific vial — appearance, reconstitution behaviour, or anything unexpected — email quality@blosigen.com with your lot number. We treat quality reports as priority items and aim to respond same-day.

For context on our testing thresholds and lot-publication process, see Our approach → Quality.
