One thing if say about keto sticks is that just because they don't show pink doesn't mean you're not in ketosis. They're not always the only indication. The colour you see on them is often just a sign how hydrated you are or not. The bottom line is if you kept your carbs under 90g per day you WILL be in ketosis. Impossible not to! My ketostix hardly ever show pink and I'm still losing.
As for the pharmacy lady. Well. That's why I buy mine online 

Have a good day!
