You are right it only takes 5 days of 10mg a day to saturate. Then the dosage drops to 5mg a day. But after 6 weeks the transponders down regulate. I do not know why it just says they do, I assume this comes from experiments not just some guy guessing. The info I have gotten comes from reading articles published by MRI the company coming out with CE2 ,pure creatine ethyl ester HCL,at the end of November. They are comparing it to creatine mono and saying uptake of creatine will be improved by 39 percent with no insulin spikes. So if you want to read the info I read look for a CE2 ad.
