I replied to a similar thread [1] about the details. I get labwork done as often as insurance covers it, but they don't actually test enough of the right things in my opinion. Eventually I will have my own lab equipment so I can do more extensive tests than what labs can do.

I read your other comment; I'm still unclear on your motivations. Why would you need, over the course of years, to "de-calcify my vascular system and gut"?

Is this related to some recognized malady which requires lifelong megadoses of Vitamin-D as a treatment?

Does your bloodwork show what is considered healthy levels of Vitamin D, calcium, and related biomarkers after these years of megadoses? Do doctors approve of your regimen & bloodwork results, or recommend against them?

With such an amount taken daily, do you show extremely high 25-hydroxy serum levels or do they remain in the normal range? I read your earlier comments and opinion on testing it, just curious.
