What’s the minimum usage that would warrant k cramps?

Lmao I’m still tripping over this. What is the least you’d have to do daily to damage your health? I want to keep doing k but not if I’m gonna harm myself from it. I’ve been taking about a gram every one or two weeks for the past 4 months. Never done more then a half gram in one session. Maybe I’m fooling myself taking doses daily? I may aswell do a fat session every two weeks? Idk
