How this whey fits your day

Lean protein that fits your macros and your training.

Lean muscle support

Training stresses your muscles. Each serving gives you 22 g of protein from whey isolate. Enough daily protein, plus training, supports muscle repair and maintenance.

Easy on your macros

120 calories, 4 g carbs and 1.5 g fat per serving. It fits cuts, recomp phases and busy days when you need protein without a full meal.

Isolate, not concentrate

Isolate is filtered to remove most of the lactose. Many people find it easier on the stomach than concentrate. It is still made from milk, so it is not lactose-free.

Sweetened with stevia

No sucralose, no ace-K, no sugar alcohols. Two cocoa powders and natural flavors give it the chocolate taste.

What this whey helps with day to day

Protein you will actually drink after hard sessions.

Muscle repair support

22 g whey isolate per serving supports recovery when paired with training.

Macro-friendly protein

About 120 calories with a lean profile for cuts, recomps, or maintenance.

Easier daily protein targets

Use post-workout or between meals when food protein is hard to hit.

Built to mix

Sunflower lecithin helps the powder blend in a shaker. Use cold liquid and shake well.

Is this whey right for you?

Built for lifters who care about macros and digestion. Not a dessert shake.

A great fit if you...
  • Train 3-6x per week and need reliable protein
  • Want isolate with lower carbs and fat
  • Prefer chocolate that mixes smooth
  • Watch digestion and hate chalky shakes
  • Stack with creatine and Hydromend
Maybe skip it if you...
  • Have a milk allergy or avoid dairy
  • Want a meal-replacement mass gainer
  • Only want plant protein
  • Will not use it consistently around training
  • Need a pre-workout. That is Inferno.

How to use this whey isolate

2 scoops. Cold liquid. Done.

1

Mix

Shake 2 scoops (35 g) with 8-12 oz cold water or milk.

2

After training

Have a serving after training if that is easiest. Total daily protein matters more than exact timing.

3

Anytime protein

Use between meals, or blend into oats, yogurt, or smoothies.

What's inside

Straightforward isolate formula with a few practical extras.

Whey protein isolate (22 g protein)

The only protein source. Filtered to remove most of the fat and lactose.

Lean macro profile - ~120 calories

Low fat and low carbs for cuts and recomp phases.

MCT oil powder

A small amount. Total fat is 1.5 g per serving, so it is not a real energy source.

Apple pectin fiber

A small amount of fruit fiber. Total fiber is 1 g per serving.

Stevia-sweetened chocolate

Two cocoa powders, natural flavors and stevia leaf extract. No artificial sweeteners.

Frequently asked questions

Clear answers before you buy.

How much protein per serving?

22 g of protein per 2-scoop (35 g) serving. All of it comes from whey protein isolate.

When should I drink it?

Any time that helps you hit your daily protein. After training is popular. Total protein across the day matters more than timing.

Does it have creatine in it?

No. Keep creatine separate so you can dose 5 g accurately every day.

Is it good for cutting?

It can help. Each serving has 22 g protein for 120 calories. Higher protein helps you keep muscle while you eat less. Fat loss still comes from your overall diet.

What does it taste like?

Chocolate. Mix with cold water or milk. Adjust liquid for thicker or thinner texture.

Is this a subscription?

No. One-time purchase is the default. If Subscribe & Save is offered, you can choose it. You are never forced into a subscription to buy this whey.

How fast does shipping take?

Most US orders arrive in about 3-8 business days after they ship. You will get tracking when the order goes out.

What if I do not feel a difference?

Email us within 90 days of delivery. We refund your first one of each product, even if it's opened, and you keep it. Send back any unopened extras for a refund too. Shipping fees may not be refunded.

Does this replace food, sleep, or training?

No. This whey is daily support, not a replacement for sleep, real food or training.

Is it OK if I'm lactose intolerant?

It is not lactose-free. Isolate usually has under 1 g of lactose per serving, and many lactose-intolerant people handle that fine. Start with a half serving. If you have a milk allergy, avoid it.

How much protein do I need per day?

For people who train, about 1.4 to 2.0 g per kg of bodyweight per day (0.6 to 0.9 g per pound). Gains level off around 1.6 g/kg for most people. Food comes first. A shake fills the gap.

Isolate vs concentrate: what's the difference?

Isolate is filtered further, so it has less lactose, fat and carbs. Both build muscle equally when total protein is the same. This product uses isolate only.
