I just received an order of melanotan 2 and mixed a 10 mg vial with 2 ml bac water. My question is in order to inject a .5 mg dose on a half cc pin what ml do i fill it up too

Figured out it was 5 clicks but how do you determine how much is a click.

You would fill it 1/10 of an ml

2ml of water mixed to 10mg equals 5 mg for each 1 ml. You want 1/2 of an ml so split 1 ml 10 times. that is your dose.
