If you take it before your workout and don’t puke, there is no reason you will puke taking it during your workout. Eat a meal w/ a slower digesting protein(eggs,chicken,tuna,beef,Grow!) and some oats(amount depends on total kcal intake and carb intake) 60-120 min. before your workout. The time depends on your ability to workout w/ some food in you. With a proper pre-workout meal, you will be fine taking your surge or whatever post-workout. I eat 2/3 cup oats+a piece of fruit and 30-40g of protein 1.5 hrs pre-workout. Right after my workout I have 30g of malto,8 oz. skim milk, 8 oz. water, and 25g of whey. An hour later I’ll have a turkey sandwich on whole wheat w/ veggies+a banana sometimes. Other times i’ll have an orange or banana, 1/2-1 cup of oats and 30g of protein(usually a can of tuna or some Grow! mixed into my oats). This is very simple and effective. Just make sure you get enough protein+carbs around your workout. Make sure you train smartly and take care of your nutrition during the rest of the day, and you’ll be fine. Hardly anyone will notice that much of a difference in worrying over the small details. Great results will be achieved as long as one combines hard, heavy, and smart training, proper nutrition, and smart life choices. Worrying about other details is splitting hairs.
