Yes, it has good effects (at least short-term). High-intensity interval training (avoids burning muscle) or weight lifting are especially good. It also enhances the effects of things like Piracetam and Acetyl L-Carnitine, which in turn enhance capability/capacity during exercise (piracetam helps with oxygen usage, in addition to being a nootropic, and Acetyl L-Carnitine helps with endurance-- so much so that many bodybuilders use the PLCAR form before workouts and the LCLT form after workouts (to speed recovery and minimize the odds of DOMS)).
