FAQs

Do you carry Serious Mass in smaller sizes?

We also carry it in a smaller 6lb container.

Can I take less than the full serving?

You absolutely can. If 1,250 calories is too much, just cut the serving down to half or a quarter. At that point, Serious Mass turns into a great mid-day calorie boost or post-workout shake.
