Only one person here has replicated the rat dose exactly, with no scaling; that would be Anthony. For something like this, it's common to use a conversion factor that takes into account the difference between rat and human metabolism, which would scale the rat dose by 1/6. If you do that, each dose would be 150/6 = 25mg. If you want to follow Baati's protocol exactly, then you wouldn't split the dose up into daily doses, but would have a single dose every one or two weeks in the later phases.
However, there's really no reason to believe this is optimal, though it worked pretty good for the rats. I could make an argument that it would be better to take large doses even less frequently.
People here have tried a variety of doses, ranging from as little as 0.5mg/day to 140mg/day. There is absolutely no correlation between dose and "feeling something", at least as far as people have reported here. The minimum dose required is probably less that 1mg/day, so if you take a lot more, you just load up your membranes with C60. That's not a bad thing- it means you don't have to take it for some number of days, weeks, or months, until it finally clears out.
You're assuming that 1ml = 1mg, which is probably not right. Sarah Vaughter says her stuff is 0.9mg/ml, while Carbon says his is 0.8. People who've made their own have often used slightly lower concentrations- I have a batch that's ~0.67mg/ml, for example.
Niner, I am guessing that you use the "loading up your membranes" option. Am I right?
