Hello,

I'm more than glad to assist you today. Yes, you can share the six pack kit as long as each individual has their own Navica account. I hope this information helps.

Best,

The fact that the site only allows you to initially associate only three names is somewhat misleading. They do this to encourage you to buy two tests per person, in my opinion.
