Tim Ferriss's daily system for performance and recovery.

Combining Grass-Fed Whey Protein, the highest quality Creatine Monohydrate, and Magnesium L-Threonate, this stack supports strength, cognitive performance, quality sleep.*

Tim Ferriss's Performance Stack combines three products designed to support the areas that matter most for long-term performance: recovery, cognitive function, and sleep. Together, they help create the consistency needed to perform at your best day after day.*

Support Strength and Recovery

  • Grass-Fed Whey Protein provides high-quality protein to help support lean muscle development and post-workout recovery.*
  • Creatine helps support strength, power output, and physical performance.*

Support Brain Health and Cognitive Performance

  • Creatine helps supply energy to both muscle and brain cells, supporting focus and cognitive performance over time.*
  • Magnesium L-Threonate helps support memory, learning, attention, and overall brain health.*

Promote Restorative Sleep

  • Magnesium L-Threonate helps support relaxation and quality sleep, allowing your body and mind to recover for the next day.*


Built around the products Tim Ferriss uses himself, this stack delivers a simple daily routine for supporting physical and mental performance.*

Grass-Fed Whey Protein

Protein is one of the foundational building blocks of muscle tissue and plays an essential role in recovery, performance, and overall health. Whey Protein Isolate delivers a highly bioavailable source of essential amino acids, including naturally occurring leucine, which helps stimulate muscle protein synthesis. We also include ProHydrolase® to support protein digestion and absorption.*

Creatine

Creatine helps replenish adenosine triphosphate (ATP), the body's primary source of cellular energy. Because both muscle and brain cells rely heavily on ATP, creatine supports not only physical performance and recovery, but also cognitive performance and mental resilience. Consistent daily supplementation helps increase intramuscular phosphocreatine stores, providing readily available energy during periods of high demand.*

Magnesium L-Threonate

Magnesium L-Threonate (Magtein®) is a unique form of magnesium shown to increase magnesium levels in the brain more effectively than other forms of magnesium. Magnesium plays a critical role in hundreds of enzymatic reactions involved in neurotransmitter signaling, protein synthesis, nerve function, and cellular energy production. By supporting healthy magnesium status in the brain, Magnesium L-Threonate helps support memory, learning, attention, focus, and sleep quality.*

This curated stack supports the key pillars of long-term performance: recovery, cellular energy production, cognitive health, and restorative sleep.*

Grass-Fed Whey Protein: Mix 1 scoop with 12 oz of water, milk, or your favorite smoothie once daily. Ideal post-workout or anytime you need additional protein.

Creatine: Mix 1 scoop daily with 6–8 oz of liquid. Timing is flexible. Consistency matters more than when you take it.

Magnesium L-Threonate: Take 3 capsules 30–60 minutes before bed to support relaxation and quality sleep.

Grass-Fed Whey Protein Isolate

Chocolate

Grass-Fed Whey Protein Isolate, ProHydrolase®, Natural Flavors, Cocoa, Salt, Monk Fruit Extract, Stevia.

Vanilla

Grass-Fed Whey Protein Isolate, ProHydrolase®, Natural Flavors, Salt, Monk Fruit Extract, Stevia.

Unflavored

Grass-Fed Whey Protein Isolate, ProHydrolase®.

Our Whey Protein Isolate is sourced from grass-fed dairy and formulated with ProHydrolase®, a digestive enzyme blend that helps support protein digestion and absorption. By using whey isolate instead of whey concentrate, we deliver more protein with less lactose and fewer calories while omitting unnecessary fillers and artificial ingredients.*

Creatine

Ingredient: Creatine Monohydrate

Momentous Creatine contains only one ingredient: creatine monohydrate. Our Signature Spec Creatine is held to the highest standard and undergoes testing protocols that extend beyond typical industry requirements, including screening for contaminants like microplastics and PFAS. The ultra-fine, highly micronized powder mixes easily and leaves no grit behind.

Magnesium L-Threonate

Magnesium 145mg (from 2g Magtein® Magnesium L-Threonate)

Other Ingredients: Rice Flour, Hypromellose (Capsule), Magnesium Stearate, Silica.

Magtein® Magnesium L-Threonate is a patented form of magnesium specifically designed to support magnesium levels in the brain. The formula is intentionally simple and free from unnecessary additives, delivering targeted cognitive and sleep support through a clinically studied ingredient.*

    Creatine - 90 Servings
    Rated 4 out of 5 stars
    Creatine purchase - questions??

    I am puzzled. I first purchased Creatine from Momentous several months ago based on an interview I saw from one of your founders, I think. A very smart woman. who was being interviewed on the podcast, Diary of a CEO. She said not all Creatines are created equal and Momentous was different. She further stated that their brand is from Germany and appears to have a crystalline texture rather than the usually powdery one everyone else has.

    Upon receiving the product, it was exactly as she described. I was very pleased and could tell the difference. When I received a new (2nd) shipment, it has a label on the top stating higher quality and superior fixability. However, there is no information where it was produced, i.e. Germany?? and the texture was not crystal like but rather powder just like other brand names which I discarded upon receiving my original.

    I have to wonder what happened to the crystal like product made in Germany. Please tell me your company is not sacrificing quality based on some other reason. To me quality and TRUST is everything in a product like this. Am I wrong??
