As part of its ongoing process to make AP course and exam materials more effective for teachers and their students, the College Board released to educators a redesigned AP U.S. Government and Politics Curriculum Framework (.pdf/3.1MB). The redesigned course and exam will launch in the 2018-19 school year.
Ideally, best times of day to supplement with creatine would be around 30 minutes to 1 hour before your training session and immediately post-workout alongside your protein shake.
Typically, you take only 5 grams at a time. If you're in a loading phase, space your 5 gram servings evenly throughout the day. Competitive bodybuilders vary dramatically in the timing of their creatine consumption. Ideal times are before and after a workout! The reason for the varied timing of taking creatine is that it works almost any time of day. Just as it takes a week to load up in your system, one study showed it remained effective even for several weeks after stopping creatine. So take it when it's most convenient for you.
