3 oz of lean protein question

So im learning to eat and cook all over again.. So im making mini turkey meatloafs if i can figure out the following.... 

Is it 3 oz of meat before or after cooking?  Trying to figure out if i make them slightly bigger due to shrinkage or do i measure them out first.

Thanks for any help

I measure out 3 ounces after it is cooked.  Years of Weigh****chers taught me that! 

When I make meatballs, i start with about 1.2 ounces or 1.7 ounces each -- and then they come out to be 1 or 1.5 ounces each.

do you have a good recipe you;d like to pass on!?!?!

If you use the seach feature above and type in meatballs; meatloaf; any food you want - you can usually find some good recipes.

1 pound turkey (93% lean)
1 egg
splash of fat free milk
1/4 cup panko bread crumbs
1/2 tsp thyme or to your preferences
1/4 1/2 Tsp Rubbed Sage

Spray a muffin tin with olive oil spray,  fill with 1/2 cup of mixture and Bake in a 350 oven


I got 6 but some were at 3.25 or 3.5 ounces after baking.  Still experimenting but my daughter who doesnt like turkey even said it was good
