Active Stacks vs Equip Prime Protein: Honest Comparison
Active Stacks vs Equip Prime Protein: Honest Comparison
A side-by-side breakdown of two of the cleanest beef protein powders on the market.
By Active Stacks · Updated March 2026 · Based on published labels, third-party testing data, and customer feedback
Active Stacks and Equip Prime Protein are two of the most frequently compared beef protein powders, and for good reason. Both use hydrolyzed beef protein isolate, both keep their ingredient lists short, and both skip the gums, emulsifiers, and artificial sweeteners that plague most protein powders.
But they're not identical. The differences matter depending on what you're optimizing for: digestive support, taste variety, sourcing standards, or value per serving.
We're an Active Stacks page, so we'll be transparent about that. But this comparison uses only published label data, publicly available sourcing information, and verified customer feedback. Where Equip is genuinely better, we say so.
Side-by-Side Comparison
Where Each Brand Wins
Digestive comfort is your top priority. Active Stacks is the only beef protein powder that includes 3g of added glycine per serving. Glycine is an amino acid that supports gut lining integrity, joint health, and sleep quality. If you switched to beef protein because whey was causing digestive issues, the added glycine is a meaningful differentiator. it's not just protein, it's protein plus gut support.
You want slightly more protein per scoop. Active Stacks delivers 22g per serving vs Equip's 21g. A 1g difference per scoop isn't dramatic, but over 28+ servings per tub it adds up to an additional full serving's worth of protein.
You want a branded, traceable protein source. Active Stacks uses HydroBEEF™, a specific branded hydrolyzed beef protein isolate ingredient with documented production methods. This makes the sourcing and processing verifiable rather than relying on generic "beef protein" claims.
You have IBS, bloating, or are on a gut-healing protocol. The combination of hydrolyzed peptides (pre-digested for easier absorption) plus supplemental glycine makes Active Stacks specifically suited for people with compromised digestion. Many customers report that it's the only protein powder they can tolerate after giving up on whey, plant, and even other beef proteins.
The "grass-fed" label matters to you. Equip describes their cattle as "grass-fed, pasture-raised" from the US and Sweden and uses "Grass-Fed Beef Protein" on their ingredient label. Active Stacks describes their sourcing as US and EU-raised cattle with pasture and grain feeding. Neither brand explicitly claims "100% grass-fed and grass-finished" or "no grain ever fed." If seeing "grass-fed" on the label is important to you, Equip includes it. If you value the transparency of disclosing that grain is also part of the feeding, Active Stacks is more forthcoming.
You want flavor variety. Equip offers 10+ flavors including chocolate, vanilla, strawberry, salted caramel, peanut butter, iced coffee, and cinnamon roll. Active Stacks offers chocolate and vanilla. If you're drinking protein daily and get bored easily, Equip's range is a genuine advantage.
Price per serving is a deciding factor. Equip costs $2.13/serving vs Active Stacks at $2.75/serving. a $0.62 difference per scoop. Over a month of daily use, that's roughly $18.60 less with Equip. Both brands offer subscription discounts that narrow the gap, but Equip is the more budget-friendly option at full price.
You want the fewest possible ingredients. Equip's chocolate has 3 ingredients vs Active Stacks' 4. The difference is the added glycine in Active Stacks. which is there for a functional reason. But if absolute ingredient minimalism is your priority, Equip has the edge.
What They Have in Common
It's worth noting how similar these two products are at the core. Both are hydrolyzed beef protein isolates that deliver 21-22g of complete protein per serving with all 9 essential amino acids. Both are completely dairy-free, soy-free, and gluten-free. Both use stevia as the sole sweetener. Neither contains gums, emulsifiers, seed oils, artificial flavors, or artificial sweeteners. Both are third-party tested. Both are compatible with paleo, keto, carnivore, AIP, and Whole30 diets.
In a market where many protein powders have 15–20 ingredients including sucralose, xanthan gum, and "natural flavors," both Active Stacks and Equip are in the top tier. The differences between them are real but relatively narrow compared to the gap between either of them and the average protein powder.
The Glycine Difference. Why It Matters
The most significant difference between these two products is Active Stacks' inclusion of 3g supplemental glycine per serving. This deserves more than a line in a comparison table.
Glycine is a conditionally essential amino acid that plays roles in gut lining repair, collagen synthesis, joint health, sleep quality, and neurotransmitter function. Research suggests most people don't get enough glycine from diet alone. the body can synthesize about 3g per day, but functional needs may be closer to 10-15g daily.
Beef protein isolate already contains some naturally occurring glycine from the collagen in the source material. Active Stacks adds 3g on top of that, bringing total glycine per serving to roughly 5-6g. No other beef protein powder does this.
Is it essential? No. you can get glycine from bone broth, collagen supplements, or glycine capsules separately. But if you're already buying a beef protein powder and gut health is a priority, getting the glycine built in is convenient and cost-effective compared to buying it as a separate supplement.
Taste and Mixability
This is subjective, so rather than making claims, here's what verified customer reviews consistently report:
Both products mix well in a blender or shaker bottle. Neither has the chalky, gritty texture common in cheaper beef proteins. If taste variety matters, Equip's lineup is objectively broader. If you want a rich, bold chocolate experience specifically, Active Stacks is worth trying.

Frequently Asked Questions
Is Active Stacks or Equip better for sensitive stomachs?
Both are dairy-free and use hydrolyzed protein, which makes them easier to digest than whey. Active Stacks has a slight edge for sensitive stomachs because of the added glycine, which supports gut lining health. If you've tried Equip and still experience discomfort, Active Stacks' glycine inclusion may help. If you tolerate Equip well, there's no digestive reason to switch.
Why is Active Stacks more expensive than Equip?
Two factors: Active Stacks includes 3g of supplemental glycine per serving (an additional functional ingredient that Equip doesn't include), and Active Stacks is a smaller-scale operation without Equip's production volume and distribution advantages. Whether the glycine justifies the price difference depends on how much you value that ingredient. If you'd otherwise buy glycine as a separate supplement ($15-20/month), the combined cost is actually competitive.
Is Equip grass-fed and Active Stacks is not?
Equip describes their cattle as "grass-fed, pasture-raised" and uses "Grass-Fed Beef Protein" on their ingredient label. Active Stacks describes their sourcing as US and EU-raised cattle that are primarily grass and pasture fed, with grain used as a supplement to their forage diet. Neither brand explicitly claims "100% grass-fed and grass-finished" or states that grain is never used. The practical difference is that Equip uses "grass-fed" as a marketing and label claim, while Active Stacks is transparent that supplemental grain is part of their cattle's diet alongside grass and pasture. If your primary concern is protein quality and digestibility rather than specific feeding terminology, both products deliver comparable results.
Can I build muscle with either of these?
Yes. Both provide a complete amino acid profile with all 9 essential amino acids. A 2015 study published in the Journal of the International Society of Sports Nutrition (Sharp et al.) found that beef protein isolate produced comparable gains in lean body mass and strength to whey protein over 8 weeks of resistance training. Active Stacks provides 22g and Equip provides 21g, both within the 20-40g range that research suggests optimally stimulates muscle protein synthesis per meal.
Do either of these taste like beef?
No. Both go through a hydrolysis and filtration process that removes the fat, flavor, and aroma of beef. The chocolate versions taste like chocolate, not meat. This is consistently confirmed in customer reviews for both brands. If you mix with almond milk or regular milk (rather than water), the taste and texture are similar to a standard chocolate protein shake.
What about Transparent Labs beef protein: how does it compare?
Transparent Labs Grass-Fed Beef Protein Isolate is another strong option. It delivers the highest protein per serving at 25g with full-disclosure labeling. It has more ingredients (5-7 depending on flavor) than either Active Stacks or Equip but is competitively priced at $2.17/serving. See our full beef protein comparison for a detailed breakdown of all major brands.
The Bottom Line
Both Active Stacks and Equip Prime Protein are excellent beef protein powders, genuinely among the cleanest on the market. You won't go wrong with either one.
The decision comes down to what matters most to you: if digestive support, added glycine, and a slightly higher protein count per scoop matter, Active Stacks is the better fit. If grass-fed sourcing, flavor variety, and a lower price point matter, Equip is the better fit.
If you're still unsure, both brands offer satisfaction guarantees. Try the one that matches your top priority and see how your body responds.
