After a lot of searching and studying, I bought this specific supplement in pill form for my daughter who is preparing for the army and exams. She is underweight and has low endurance despite being an athlete. In combination with protein, multivitamins, and weights, on the second day after she started taking it and had track practice, she noticed the difference in her endurance by herself. She was positively shocked. In another case, her blood pressure would have hit the red zone, her head would have felt like it was going to explode, and she would have gotten tired much earlier than the expected target. She takes three capsules in the morning and three in the afternoon for recovery. It goes without saying that the pain in her body after exercising is less. I hope she continues like this. I recommend it for now. If anything changes negatively, I will return for an update.
