FAQs

Do I take D1 : Mass Stack instead of protein powders? With protein powders?

Combining D1 : Mass Stack with a complete diet that matches your fitness goals will result in the biggest gains. In many cases, use of protein powders can be very helpful in reaching your macro-nutrient and caloric goals every day. At D1 Lab, we have had success with and without protein powders in our daily diet regimen. *

Do I take D1 : Mass Stack every day or only on days I exercise?

We recommend taking D1 : Mass Stack every day, as several components of our supplement are just as effective on non-exercise days as they are on exercise days. As an example, the use of L-Citrulline has been shown to increase nitric oxide (NO) production, and research further demonstrates that supplementing the nitric oxide (NO) pathway on rest days can improve production of critical muscle building hormones, such as hGH. *
