What Momentous makes, and why we feature it
Momentous makes protein, creatine, sleep and recovery supplements. We feature Creatine, with 5 g of creatine monohydrate as the only ingredient and 90 servings a jar, and Whey Protein Isolate, with 20 g of grass-fed whey per scoop and 25 servings a tub, per Momentous.
Third-party certification is the reason they are here. NSF lists the creatine's 450 g jar and the whey's Chocolate and Unflavored versions as NSF Certified for Sport, and Momentous publishes batch certificates of analysis for both, though it does not name the testing labs.
Testers and owners rate both well. BarBend testers scored the whey 5 of 5 for taste and solubility, and owners give the creatine 4.8 from 3,953 verified reviews on Momentous's store and 4.5 from 3,366 on Amazon. Price is the trade-off: Garage Gym Reviews scored the whey's price 1 of 5.

Momentous also posts batch certificates of analysis for both products, though it does not name the labs.

The Whey Protein Isolate is also NSF Certified for Sport in Chocolate and Unflavored and mixes clean per BarBend testers, but costs $2.80 a serving bought once.
What is Momentous's return policy?
Momentous offers a 30-day money-back guarantee on its Whey Protein Isolate, per the product page. The creatine page also lists a money-back guarantee but does not state its window or whether opened product qualifies, so check with Momentous before you count on a refund.
Where are Momentous products made?
