Well, it is a two-folded question. On one side, Iknow that Dspark can be helpful, and some pre-workouts as well.However, those based on stims can hit you back with adrenal fatigueand the so called caffeinne crash. This can happen during sex, so Iam not sure about those stims. Dspark has no stims, so it is fine touse – at least it won't make things worse.
