How much caffeine is in G Fuel Energy (can)?

Some flavors are 140 mg; the standard high line is 300 mg.
Will G Fuel Energy (can) affect your sleep?
From 300 mg, a high-line G Fuel needs about fifteen hours to fall under 50 mg, so a midday can can still be active at bedtime. Late-night gaming sessions on these can wreck your sleep.
Heads up
At 300 mg, a second G Fuel Energy (can) in a day pushes you toward the FDA’s 400 mg ceiling — and that’s before any coffee or tea. Log everything in the calculator to see your real daily total.
