To be under 50 mg of residual caffeine at an 11 PM bedtime, have your last 330 ml can of NOCCO BCAA (180 mg) by 1:45 PM (13:45). The math uses the median 5-hour caffeine half-life; individual half-lives range from about 2 to 12 hours.
NOCCO BCAA Last-Call Times by Bedtime
Latest time to finish a 330 ml can of NOCCO BCAA (180 mg of caffeine) and still be under 50 mg of residual caffeine at bedtime, assuming the median 5-hour half-life. Your personal half-life may sit anywhere in the 2 to 12 hour range.
| Bedtime | Last call for NOCCO BCAA | Residual at bedtime |
|---|---|---|
| 9:00 PM (21:00) | 11:45 AM (11:45) | ~50 mg |
| 10:00 PM (22:00) | 12:45 PM (12:45) | ~50 mg |
| 11:00 PM (23:00) | 1:45 PM (13:45) | ~50 mg |
| 12:00 AM (00:00, midnight) | 2:45 PM (14:45) | ~50 mg |
Clearance Time by Serving Size
How long each serving of NOCCO BCAA needs before bed to drop under 50 mg:
| Serving | Caffeine | Time needed before bed |
|---|---|---|
| 330 ml can | 180 mg | 9 h 15 min |

How the Math Works
Caffeine leaves your body by exponential decay. With the median 5-hour half-life, the 180 mg in a 330 ml can of NOCCO BCAA falls to 90 mg after 5 hours and 45 mg after 10 hours. To get under 50 mg, the level where caffeine stops measurably delaying sleep for most people, it needs about 9 h 15 min of clearance time. Subtract that from your bedtime and you get the last-call times above, rounded down to the nearest 15 minutes.
The big caveat: the 5-hour figure is a median. Depending on CYP1A2 genetics, medications, smoking, and pregnancy, real half-lives run from about 2 to 12 hours. If caffeine reliably keeps you up, treat these times as too generous and move your personal cutoff earlier, or model your own curve in the caffeine half-life calculator.
