Latest time to drink it

For an 11 pm bedtime, most people should finish one scoop (29.6 g) of Pre-Kaged by about 10:20 am. The table works it out for other bedtimes and for how sensitive you are: it is the latest time to start one so that the caffeine left stays under the line all night.

Bedtime	Very sensitive under 25 mg	Average under 50 mg	Not very sensitive under 100 mg
9 pm	Too much for one evening	8:20 am	1:20 pm
10 pm	Too much for one evening	9:20 am	2:20 pm
11 pm	5:20 am	10:20 am	3:20 pm
Midnight	6:20 am	11:20 am	4:20 pm
1 am	7:20 am	12:20 pm	5:20 pm

For one scoop (29.6 g) of Pre-Kaged, average clearance (half-life 5 h), 8 hours of sleep. "Any time" means even one at bedtime stays under the line.

How long it lasts

Method and limits

The caffeine figure comes from kaged.com; recipes, brewing and batches vary, so a real serving can differ. The curves use a standard one-compartment model with an average 5-hour half-life and a sleep-friendly line of 50 mg; your own body may clear caffeine faster or slower. How it works has the details.

These are estimates for information, not medical advice. If you are pregnant, ask your doctor; common guidance is under 200 mg a day.
