How many times do I have to get hit by Maunza?

One of my best friends is currently receiving Maunza injections. She goes for a weekly injection, and when I asked her, she told me she is about to receive her sixth. I had a lot of questions, so I asked her various things, and she said she has lost a total of 6kg so far. However, when I asked how many rounds she would need, she said she didn't know herself. So, I am wondering if there is a set number of Maunza injections, or if she can continue receiving them until she reaches her target weight loss. Please let me know what the maximum number of injections she has received is and if there is a limit on the number of doses.
