How do you tell the difference between the drug working and just a good week?

Log dose, time and sleep. Ten seconds a day and it turns the anecdote into something you can look at. Same for me with tesamorelin, unfortunately.

Is it normal to feel worse before better? Nobody told me that.

Worth repeating that this is not medical advice and the answer often depends on who you are.

Following this because I am in the same place and have no idea what to ask at the appointment.
