from a science nerd point of view....
for the person in the graph, 2g is maintenance dose.
at 3g/day (1g above maintenance), it took at least 28 days (probably 30-32) to reach saturation.
thats an extra 28-30 grams above maintenance to reach saturation.
20g for 6 days (120grams) definitely reached saturation.
But 20g/day might have reached saturation after only 2 days (ie, 40grams)
i'd suggest a hypothesis (based on that graph) that 4g/day (2g extra) would reach saturation after 2 weeks, 5g per day after 1-2 weeks....
saw a study last night that said CM is 100% absorbed, except for th ebits broken down by acid in the gut before being absorbed.
con-creat is C-HCl, and when it dissolves in 4-6oz water, the pH is 2 (similar to gut) but is stable for 60 days...
that suggests that when swallowed, and it dissolves in the stomach, it will be more or less at equilibrium with the stomach pH, and not be broken down, allowing a higher % of it left to be absorbed, compared to CM...
maybe thats why 1.5g/100kg of C-HCl is enough compared to 2-3g/100kg for CM??
that whole "microdose" thing is probably just to do with the below graph.. only need to take a little bit extra to achieve saturation relatively quickly)
edit, graph made into sensible size... can't upload to forum as permanent image tho? please save to your PC if you want to keep.
