Ok, ima give ya some advice because your where i was years ago. Good job on coming on here to get advice, step well taken...however, heres some mistakes you made.
1: Read the stickies at the top of the boards, lots of good topics and Supplement reviews, and training tips.
2: Never rely on supplements to get the gains you want, you will jsut be let down. You need to worry about your diet and your training, not sell-tech "hardcore"
3: Never go to GNC, you will just get ripped off. It doesnt matter if its "Reduced" or "On sale", its just a lowered price from the original rip off price. Order your stuff online at bulk nutrition or body building. Cheap and shipping is usually cheap or free. If you have a VitaminShoppe or MuscleMag close that works too.
4: As mentioned above, DIET. Its all about the red meats, carbs, fish , pasta all that good stuff, you put in a well honored diet you will get well honored results...food gives you better results then supplements do, ask anyone.
Now, with that being said, dont get all discouraged from taking Nitrotech, hell , i have a bottle 2 feet away from me. Why? Because im stuck on an island inside a military base where the only good supp they sell is nitrotech and its cheap. However, even I am ordering from Bulk nutrition tommorow for my supplements
. What does your diet and training schedule look like?
