Yeah pretty much this. I took creatine back in high school/college to build muscle mass. In those days we would load with 20g for a week -> then do 5g for 8 weeks -> cycle off for two weeks -> repeat.

I'm back on it now for endurance sports (trail running + cycling) and the advice is to just take 5g a day and don't worry about cycling off. At 5g/day it takes 4-6 weeks to saturate your muscles.

It does have a noticeable impact on water retention, so this year I cycled off six weeks away from my "A" race and lost 5lbs of water weight. It was a 100 mile mountain ultra so I thought the extra pop on the climbs probably wasn't worth the extra weight over the entire course (but probably was worth it while doing hill reps in training). Next year I'm sticking to shorter stuff where I'll run up more climbs. For those I don't plan to cycle off.

I've taken creatine for 20+ years, nobody does the "loading" dose anymore, or shouldn't be if they still do. Maybe it stills says it on the jars but there was tons of information a decade or more ago that it was deemed as a way to get you to blast through your jug faster. 5g is the normal dose. You're always taking in creatine eating normal meat added meals.

This is giving me flashbacks to using bodybuilding.com forums.. man, long time ago.

It is my 100% always buy supplement. I only have 2 of those now, protein the other. It absolutely helps me think better and feel better throughout the day. Noticeable when I stop taking it. And its dirt cheap. If I had more disposable income I'd have a few others but I went from tons of supplements to basically nothing. I never use PWOs or anything now, even when I do have money.

Not a typo, 20g+ a day.

Dosing for gym exercise is different than dosing for excess creatine to reach the brain.

Well studied, checked with my doctor, including for TBI. Obviously everyone should check for themselves.
