I'd get a solid grasp of your diet first. I haven't used that supplement, but as a (former) skinny guy here are the supplements that I use and work well.
1) Whey Protein(Muscle Milk)
2) Fish Oil(Carlson's Very Finest Liquid Fish Oil)
3) Multivitamin(Take your pick)
4) Creatine(Experiment with different kinds)
5) Workout Shake(Optimum 2:1:1 Recovery)
At 17 I lacked the discipline to follow a strict diet protocol, so getting the discipline and workout routine down at your age will pay many dividends in the future, not only in getting more girls but developing successful life habits as well.
But for the OP and those who are trying to bulk, here are a couple of quick tips and meals. Simple and easy to fit into your day.
1. Drink one workout shake during your workout and one immediately after.
2. Make a couple of premade shakes and take them with you to work or school. I posted one I use in
this thread.
3. Have a simple pre-bed snack. I like to mix cottage cheese, peanut butter, and a little bit of a whey/casein protein blend. Doesn't sound to appetizing but it's actually not that bad. If the blandness bothers you, I guess you can add a calorie free sweetener.
4. I weigh myself every two weeks and at the same time take BF measurements with calipers. Based on these results I change my caloric intake or keep things the same.
