1
Protein you can finish
10g of complete protein in a light, cold glass designed to feel manageable even on a lower-appetite day.
When your appetite disappears, protein becomes the hardest part of the day. Every shake on the shelf was made for someone who's hungry. Mainstay was made for someone who isn't.
The Mainstay protocol
Three simple parts. That’s the whole thing.
Protein gives your body the raw material. Creatine helps support your strength. And a routine you can actually stick to is what makes both count.
2
Daily creatine
A full 5g daily serving in gummy form, making it easier to build creatine into the same routine.
3
Every morning, in 30 seconds
One scoop, cold water, done. No blender, no heavy shake and no complicated routine.

Game changer
I put it in water and it tastes sooo good! No chalky feeling, just a fine taste. I love it! And it doesn't feel like additional effort taking it. Thank you Amber!❤️
