Why This Combo

Cuts get hard because hunger and boredom both spike. This stack tackles both.

Total Monthly Cost

Math based on 40 isolate scoops, 30 clear whey scoops, and 2 boxes (24 bars) per month:

Monthly cost math
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.

Frequently Asked Questions

Why isolate and not regular whey?

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.

Can I drop the clear whey and just use isolate?

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.

How much protein do I need on a cut?

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.

Are protein bars worth it on a cut?

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.

Will I lose muscle on this stack?

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.

Can I use these products on a keto diet?

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.
