I train not professional, but only over time more or less about my weight to keep it under control and to ensure a certain level of fitness. After long runs or when I run several days in row face occasionally muscle fatigue, and I often have to pause for several days.
My goal for the intake of BCAA was the regeneration phase shortening in this case, which is why I once taken on training days when needed immediately after training 2-3 capsules (depending on condition). See the capsules at first glance quite large from, but can be easily swallow with some liquid.
The effect was clearly noticeable and much larger than I expected. On days where I have previously would normally pause for several days, no more fatigue was noticeable the next morning.
Conclusion: The effect is clearly noticeable and recommended the product in any case ...
