Will Pre JYM Pre-Workout affect your sleep?

From 300 mg, Pre JYM needs about fifteen hours to fall under 50 mg, so even a midday scoop can still be present at bedtime. Evening training on this dose can seriously cut into your sleep.

Heads up
At 300 mg, a second Pre JYM Pre-Workout 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.
