Checks out. — Legitimate

This dose sits within the 20-40g clinical range shown to support muscle protein synthesis after exercise.
Examine.com whey protein research summary -
"No artificial sweeteners, colors, or added sugars"
Label lists only stevia as sweetener with natural flavoring, consistent with the no-additive claim on the page.
-
"Blend of concentrate, isolate, and hydrolyzed whey gives 'complete digestion curve'"
All three forms of whey digest within a similar few-hour window; the practical difference in recovery is small, not a game-changer.
Internal: whey protein digestion kinetics comparison -
"$124.90 for 5lb (75 servings) grass-fed whey"
Works out to about $1.67 a serving, roughly 3-4x the cost of standard commodity whey but in line with other grass-fed competitors.
Consumer advice
This is a legit protein powder with transparent dosing (23g protein/serving, no hidden blend). If grass-fed/hormone-free sourcing matters to you, this is reasonably priced for that niche. If it doesn't matter, a standard whey isolate or concentrate from any major brand will do the same job for less. Ignore the "4th of July" discount code framing - it's normal e-commerce, not a red flag.
Claims vs Evidence
MODEST2 of 4 claims supported by evidence. These grades score the marketing, not the product — a claim only counts as supported when the label discloses a dose that matches the studies behind it, so blends that hide doses cap at “partial” no matter how good the formula is.
