1.) Most sources claim you need about 1 gram of protein per 1lb of body weight for an athlete, meaning a 150lb person would require 150 grams of protein per day. Other sourced claim you need more if your heavy lifting type workouts. Whether or not you want to gain muscle, or maintain muscle is also another factor. So protein is dependent on body weight, level of activity, and your body weight gain/maintenance goals. Protein is by far the most expensive ingredient and the protein in my recipe is bulk 44lbs of protein. Which is a big investment for protein powder but its also by far the best deal on the internet hands down.

2.) Dextrose is a fast absorbing carb that spikes your blood sugar, mainly used for post workout carbs. So don't eat dextrose all day, just after workouts.

3.) Shipping is factored in on all websites, except Im not sure if you have Amazon Prime. Luckily I just use my parents so I get free shipping on all the amazon ingredients which saves money. You could use someone elses if you know anyone who has it.

4.) You can find much cheaper multivitamins, but this one doesn't include calcium or magnesium which affect the absorption of other vitamins. Which is why you want to consume most vitamins and minerals at a different time than you would consume calcium. You can read up on it more on the internet.

5.) Again, take into account your current body weight, your level of daily activity and your goals as to whether you want to gain weight, maintain weight, or lose weight.
