Hi, Nutrigain is a type of weight gainer supplement that can help increase muscle mass, but it should not be considered a substitute for a healthy diet and regular exercise. It is important to speak with a healthcare professional before starting any supplement regimen, especially if you have any pre-existing health conditions or are taking any medications. It is important to note that building muscle takes time and consistency. Three months is a relatively short period to see significant muscle gain. Consuming enough protein, carbohydrates, and healthy fats and regular strength training is crucial for muscle growth. Regarding the procedure, it is typically recommended to consume weight gainer supplements such as Nutrigain in between meals or as a post-workout shake. It is essential to follow the instructions on the label and not exceed the recommended dosage. The recommended serving size for Nutrigain is 30 grams, and it should be taken with milk or water. It s also important to remember that weight gain supplements can have potential side effects such as stomach upset, indigestion, and diarrhea. Drinking enough water and eating at regular intervals can help minimize these effects. In summary, Nutrigain can be a valuable supplement for increasing muscle mass, but it should be used with a healthy diet and regular exercise. Consult with a healthcare professional before starting any supplement regimen, and follow the instructions on the label. Take care. Hope I have answered your question.
