Half the amount stated on the package.
I've been using these for years. I wondered about the size of the tube when it came as it looked like the 600 tube. It was! Although it says 1200, it was only 600. Disappointed, but since I am on my own and I use them 3 x a day (2 at a time) they should have lasted 200 days. They lasted less than 100, so fair to say this is a 600 (ish!) tube in 1200 packaging.
