The Stack
Three products built for lean phases: lean macros, low sugar, low calories per gram of protein.
25g of nearly pure protein per scoop with under 2g of carbs and effectively zero fat. ISO100 is the gold standard isolate for cutting because every shake is almost 100% protein calories.
See live price →20g of fast-absorbing whey isolate in a juice-like format. Useful when the idea of another chocolate shake makes you want to quit your cut.
See live price →21g of protein per bar at around 200 calories. A 12-pack box delivers two weeks of post-workout or late-afternoon snacks for less than $20.
See live price →Why This Combo
Cuts get hard because hunger and boredom both spike. This stack tackles both.
- Isolate gives you protein without the fat and sugar. A scoop of ISO100 is 110 calories for 25g of protein, which is about as lean as supplemented protein gets.
- Clear whey breaks the chocolate-shake monotony. A cold raspberry-flavored juice-style whey at 90 calories is genuinely refreshing in week six of a cut.
- Pure Protein bars handle late-afternoon hunger. 21g protein, 4g sugar, and an actual chewy texture mean you can satisfy a snack craving without blowing your day's calories.
Total Monthly Cost
Math based on 40 isolate scoops, 30 clear whey scoops, and 2 boxes (24 bars) per month:
| Whey isolate: ISO100 Hydrolyzed Whey (40 servings/mo) | $36.61/mo |
| Clear whey: Clear Whey Isolate (30 servings/mo) | $23.99/mo |
| Protein bar (12-pack box): Protein Bar (12-Pack) (24 servings/mo) | $34.96/mo |
| Total monthly cost | $95.57 |
That's about $96/month for three products that deliver around 2,500g of supplemented protein on under 12,000 supplemental calories. Per gram of protein, that's roughly 3 to 4 cents.
How to Use Each
Dymatize ISO100
One scoop in water (not milk: save the calories) within 30 minutes of finishing training. ISO100 is hydrolyzed, so it absorbs faster than standard isolate, which matters more in a cut where you want every protein gram to count.
MyProtein Clear Whey Isolate
One scoop in 16 oz of ice water, ideally mid-afternoon or post-workout when you want something that doesn't feel like a meal. It's flavored like a juice, not a milkshake, which makes it the easiest protein to drink when your appetite is dialed-down.
Pure Protein Bars
Keep one in your bag for late-afternoon or pre-evening-gym snacks. Cap yourself at one a day on a cut. Two bars a day eat 400 calories and 8g of sugar, which adds up fast.
Cheaper Alternatives
- Swap ISO100 for Nutricost Whey Isolate at $28.95 on Walmart. Same 30g protein per scoop, half the price, slightly less hydrolyzed.
- Swap clear whey for MyProtein Clear Whey (Tropical) at $44.95. Same brand, equivalent macros, more dramatic flavor.
- Swap Pure Protein bars for think! High Protein Bar at $17.98 for a 10-pack at Walmart. 20g protein, 0g sugar (sucralose sweetened).
Upgrade Path
- Upgrade ISO100 to Transparent Labs Whey Isolate for a 100% disclosed, no-artificial-anything label. Slightly higher per gram but cleaner ingredient list.
- Upgrade the bar to Barebells Protein Bar at $26.97/12-pack at Walmart. 20g protein, no added sugar, candy-bar texture.

Isolate is 90%+ protein by weight versus 70 to 80% for concentrate. On a cut, that 10 to 20% difference is mostly carbs and fat, which you're trying to minimize anyway. The price gap is worth it for the leaner macros.
Yes, especially if budget is tight. Clear whey is a quality-of-life pick, not a nutritional requirement. The flavor change keeps morale up in long cuts, but you can hit the same macros with just isolate and water.
Most evidence supports 1.0 to 1.2g of protein per pound of bodyweight when in a calorie deficit. For a 170 lb lifter that's 170 to 204g per day. Two isolate shakes and a bar from this stack covers around 90g of that.
For convenience, yes. For value, marginal: most bars cost 8 to 12 cents per gram of protein, vs 3 to 4 cents for whey isolate. Use them strategically as snacks, not as your main protein source.
Probably not if you hit your protein target and keep lifting heavy. The stack gives you 90g+ supplemented protein per day, which combined with food meals easily hits 180g+. Muscle loss on a cut comes from protein under-eating and stopping resistance training, not from supplement choice.
ISO100 yes (under 2g carbs). Clear whey yes (under 1g carbs). Pure Protein bars no: 17g of carbs per bar from sugar alcohols. Swap them for Atlas Bar or Munk Pack if you're strict keto.
