Dymatize vs MyProtein

Overview: Dymatize

Dymatize was founded in 1994 and quietly became the technical leader in whey isolate. Their flagship ISO100 uses hydrolyzed whey (pre-cleaved peptide chains for faster digestion) combined with cross-flow microfiltration to deliver 25g of protein per scoop with just 0g-2g of carbs. Dymatize Elite 100% Whey, the brand's blend product, hits the same 25g protein at a lower price point and is a perennial value pick.

Dymatize sells at every major US retailer: GNC, Bodybuilding.com, Walmart, Target, iHerb and Amazon. Pricing falls in the $45-$75 range for a 5lb tub depending on the formula. The brand's strongest selling point is the consistency and flavor execution: Gourmet Chocolate ISO100 is widely considered the best-tasting isolate on the market.

Overview: MyProtein

MyProtein is a direct-to-consumer juggernaut founded in 2004 in Manchester, England. The brand built its empire on factory-direct prices: by selling through its own website instead of through retailers, MyProtein routinely undercuts US brands by 20%-40% on raw protein-per-gram cost. Impact Whey Protein (their best seller) delivers 22g of protein per 30g scoop. Impact Whey Isolate (the upgrade) delivers 25g per scoop at 92% protein purity.

MyProtein operates a US warehouse out of Kentucky for fast shipping, runs flavor catalogs in excess of 30 SKUs per product, and aggressively discounts via flash sales (40%-60% off is common). The trade-off is brand recognition: many American lifters have never tried it because it lives outside the GNC ecosystem.

Side-by-Side Comparison

Value Score Comparison

MyProtein wins on Value Score thanks to direct-to-consumer pricing and larger 5.5lb tubs. Dymatize wins on flavor execution and retailer availability.

• MyProtein routinely runs 40%+ off flash sales that push Impact Whey Isolate below $50 for 5.5lb. That is the cheapest premium isolate in the US market.
• Dymatize trails on raw protein-per-dollar but wins if you need same-day Amazon Prime delivery or want to walk into a GNC and grab a tub today.

Verdict: Which Should You Choose?

Pick Dymatize if:

• You want the fastest-absorbing hydrolyzed whey
• You shop at GNC, Bodybuilding.com or want Amazon Prime same-day delivery
• You value premium-tier flavor execution (Gourmet Chocolate is benchmark)
• You buy at retail and won't time your purchases around flash sales

Pick MyProtein if:

• You want the lowest cost-per-gram of isolate in the US market
• You can plan purchases around 40%-60% off flash sales
