None of the ingredients used in our personalized protein powder blends are on the NSF or NCAA banned substance lists.
Some blends may contain a single serving of non-GMO green tea extract, which contains a small amount of naturally-occurring caffeine (5 mg, approximately 1/20th of a cup of coffee). This, however, is 100 times below the acceptable limit for caffeine in NCAA athletes. As long as you don't consume 100 scoops of protein within 3 hours of a competition, you will be fine.
However, Gainful's products are not currently NSF Certified for Sport. Due to the large variety of different protein blends we produce, the certification process is especially expensive and slow – but we're working on it!
Always consult with your physician before using any dietary supplement.
