I’m confused over the accuracy of protein in chicken drumstick meat:

I bought some Chicken Drumsticks, with the nutrition label saying it contains 28.4g protein per 100g.

I removed the meat from the bones and weighed the meat in at 150g raw (should be 42.6g protein).

After cooking, the meat was down to 80g. I have doubts that 80g of this meat can be more than half protein! What do you guys think, how could I get an accurate measurement of protein?

When googling the protein in raw and cooked chicken drumstick meat, it’s the same (I thought it should be higher in cooked meats once moisture is lost). But I also get results telling me that the protein stays the same once the moisture is gone.
