I have done 1200mg/week too, which would be better for any liver issues.
That also reminds me I have oral TUDCA and milk thistle to take too. And some liver doctor on Reddit swears by black coffee for liver heath.
At 700 mg/week, my gluta kit should last about four months. Not bad for $50, especially since such Korean gluta is supposedly pharma quality regarding sterility, excipients, etc. I get it (Glutaone pink box) from the Glow-Unique website. Because of FDA regulations, it is marketed for cosmetic/topical use by that website, but it is the same Korean gluta everyone uses and says IM/IV on the box.
