Where to buy VITAMIN C IV in Moscow

This is the first time I post on a forum but we are in urgent need of VITAMIN C IV ... Does anyone have any idea where to buy VITAMIN C Intravenous ?
Thank you!

Nowadays it is of great interest for alternative therapies with Vitamin C. The oncologist has recommended this therapy for our uncle. The clinic where he does this treatment uses Vitamin C IV from PharmaLife Laboratories. We hope this therapy will work...
