The Creatine Science Just Got Way More Crazy

Why the standard 5 gram rule is too simple

The striking image at the start is not bigger biceps, but better sleep. Chris Masterjohn says the effect of creatine on his sleep was measurable, and when he compared different timing conditions, the differences were statistically significant. That sets the tone for his whole framework: creatine is not a one-size-fits-all supplement, and the literature is only a starting map, not the whole territory. He lays out the standard playbook first. A typical loading phase is about 20 grams a day for 3 to 5 days, followed by a maintenance dose of 3 to 5 grams a day. The reason for loading is mostly based on muscle data. If you skip loading, muscle creatine stores can still saturate, but it may take about a month on 3 to 5 grams daily. That is why he thinks many people who tolerate it should consider loading. It shortens the time needed to discover what maintenance dose actually works. Then he takes an unexpected turn. Instead of treating trials as commandments, he treats them as boundaries for self-experimentation. He says randomized trials suggest the useful range could be anywhere between 3 and 20 grams, and there are studies showing benefits over 6 months at 20 grams a day. But there is very little direct head-to-head work comparing 20 versus 15 versus 7 versus 5 grams, especially for brain-related effects. So the real question is not, “What dose works on average?” It is, “What dose produces the best result for the thing I care about most?” His method is concrete. Pick a metric that actually matters, sleep, strength, speed, daytime energy, or how much work you get done. Put a number on it. Start at 3 grams. Wait until the effect stabilizes. Then increase by 1 gram a day and track where benefits level off. In his own case, 20 grams during loading gave him a huge improvement in sleep. Dropping to 5 grams kept about half the benefit. Moving from 5 to 6 to 7 to 8 grams produced what he describes as a linear improvement, then it flattened around 8 grams, so he stayed there long term. He also makes room for people who react badly. He says some cannot tolerate even 3 grams, but that does not mean they do not need creatine. He has seen some do well with 100 milligrams a day, which sounds absurdly low compared with the usual 5 grams, but one person improved tolerance dramatically by staying at 100 milligrams a day for 3 months. The principle is simple and memorable: pull back to the dose that gives benefit without drawback, then slowly build from there.
