How long does a 8oz bag of pangea lasts for a single gecko?

I am curious as to how long a 8oz bag of pangea lasts a single gecko. An estimate on what to expect. I know geckos eat different amounts but I wanted to know long a bag lasts for y'all? My male usually eats a little less than the 1/2 measuring spoon in little water bottle cap. Normally eats the whole 1/2 but I just got him a week and a day ago. He's 55 grams right now.

It will last a good long while. My daughter bought the size up about a year ago and she is still working her way through it

Thank you!;
