A Modern Protein Routine To Maintain Muscle & Improve Performance

Your current tub of powder covers protein. It doesn't cover fiber, it doesn't cover collagen, and it still needs a blender. One ready-to-pour packet adds 15g of complete protein, 8g of fiber and 2.5g of VERISOL® collagen to the water bottle that's already in your gym bag.

A Training Day Has More Gaps Than Your Tracker Shows

Your tub of powder only provides protein. Our first-of-it's kind ready to pour complex gives you a boost of protein, while also helping you meat your fiber goals, often missed when focusing only on your macros.

Your Protein Is Lacking

Hitting your number for the day isn't the whole picture. Research suggests 20 to 40g per serving, spread every 3 to 4 hours.* A light breakfast or a desk lunch can fall short even when the day adds up. 15g brings that meal closer to range.

A Gram Of Protein Isn't Always A Gram Of Protein

Your app counts every gram the same. Your body doesn't. Rapidly digested proteins rich in essential amino acids are the most effective at supporting muscle protein synthesis.1 That's why ours pairs whey isolate and cultured protein with collagen peptides, which aren't a complete protein on their own.

Fiber Never Makes The Macro Split

Protein, carbs and fat get tracked. Fiber usually doesn't, and over 90% of U.S. adults miss their fiber target.* A diet built on chicken, rice and shakes runs low fast. 8g of five-source fiber supports healthy digestion and regularity.

Bloat Doesn't Get Logged

If your current shake leaves you feeling heavy, more of the same isn't the answer. Our fiber is spread across five gentle, low-FODMAP sources instead of one big dose, designed to be easy on your stomach.

Your Joints Don't Show Up In Your Numbers

Muscle gets measured. Connective tissue carries the load and gets ignored. 2.5g of VERISOL® supports joint and connective tissue health, at the dose used in its published research.

The Sugar Riding Along With Your Protein

Some protein bars and ready-to-drink shakes add sugar to make the protein taste better, and it's easy to miss on a busy label. Ours has 0g added sugar and is sweetened with stevia.

The Science Behind Our 8-in-1 For Men Who Do More

How This Helps*

Resistance training and protein work together, and rapidly digested proteins rich in essential amino acids are the most effective at supporting muscle protein synthesis.1 One protein can't do every job, so this uses three.

⚡ Whey Protein Isolate for fast-absorbing protein.

⏳ Cultured Protein for a steadier, sustained supply.

🦴 Collagen Peptides for the structural side: joints and connective tissue.

More Than Just Meeting Your Macro Goals

Sports nutrition research puts protein for people who train at 1.4 to 2.0g per kg of body weight a day, spread every 3 to 4 hours.1 Most lifters chase that number and skip everything else, and over 90% of U.S. adults miss their fiber target.*

15g
Protein

The Top-Up

Complete protein from whey isolate, cultured protein and collagen peptides. Not another 40g scoop: a 15g top-up for the meal or snack that comes up short, so your daily total actually lands.

8g
Fiber

The Gut Check

Chicken, rice and shakes don't leave much room for fiber. 8g across five low-FODMAP sources supports digestion and regularity, without the bloat of one big dose.

2.5g
Collagen

The Connective Tissue

The exact 2.5g daily dose used in VERISOL®'s published research. Supports joint and connective tissue health, the parts that take the load every time you do.
