Vintage Brawn™ is a blend of three protein sources: eggs, milk (casein + whey) and beef. It is far superior than any single-source protein like whey. Why? Because as a blend, it provides a complete amino acid profile and a powerful muscle-building effect that not only kicks in fast, but lasts for hours.

What it does

Vintage Brawn™ contains a potent dose of the Big Three proteins: eggs, milk and beef – which together work to build muscle more effectively than whey or any single source of protein. They also guard against muscle breakdown longer to support increased levels of recovery and hypertrophy, whatever time of day you take Vintage Brawn. 

We don’t add cheap aminos to spike protein content per serving at the expense of your health, which is all too common these days. With Vintage Brawn™, you know that every gram is sourced exclusively and responsibly from the best isolates – eggs and beef from the USA, and milk from hormone-free New Zealand cows. 

Third-party tested with zero concentrates, zero artificial substances, zero synthetic additives, and zero preservatives. We stand by Vintage Brawn as the best muscle-building protein powder supplement on the planet.

What's in it & why

Main Ingredients

Egg White Protein

Eggs have long been considered a perfect source of bodybuilding protein. They have a full complement of essential amino acids and they are easy to digest. However, they also contain fat and cholesterol, which is why we use only egg white protein in Vintage Brawn – sourced from eggs produced in the USA.

Milk Protein Isolate

Milk protein isolate (MPI) may be one of the most overlooked protein sources in sports nutrition. The two major proteins in milk are casein and whey. While whey tends to be absorbed quickly, casein has a “sustained-release” profile. MPI extracts these two complementary proteins from milk, leaving behind virtually all of the fat, sugar (lactose), and other nutritional “baggage".

Beef Protein Isolate

Beef has been prized as a muscle-building protein for centuries. In Vintage Brawn™, we use a beef protein isolate made from fresh beef using a USDA-approved process. It contains high levels of conditionally essential amino acids and is easy to digest. 

In clinical research, the beef protein isolate in Vintage Brawn™ was found to keep plasma amino acid levels elevated for three hours. This is considered ideal for building muscle as quickly as possible.

Other Ingredients

Dutch Cocoa (Chocolate flavors only)

Gives Vintage Brawn™ its signature rich and deep chocolate flavor. It has a more intense and smoother taste than regular cocoa.

Natural Flavors

Countless iterations of taste-testing allowed us to arrive at a flavor that is not only natural, but tastes great and mixes easily.

Vegetable-Based Antifoam (Vanilla and Coconut flavors only)

Helps reduce the formation of foam. It is made of Silica, Propylene Glycol, Mono and Diglycerides.

Organic Stevia Leaf Extract

Stevia is a natural sweetener which is extracted from the Stevia rebaudiana plant. It has no calories.

Sea Salt

Also known as Sodium Chloride, helps bring out the flavors.

Monk Fruit Extract

A natural, zero-calorie sweetener.

Xylitol Crystalline (Vanilla Milkshake flavor only)

A natural sweetener.

How to use it

Add 1 scoop of Vintage Brawn™ to 6-8 fl oz of cold water, milk, or your favorite beverage. Shake or blend for 20-30 seconds and enjoy. 

For convenience and great mixing results, try our OSL BlenderBottle™ shaker.

SUGGESTED USE: Vintage Brawn™ can be used effectively throughout the day. It’s fast-acting, yet supplies muscle-building and recovery support for hours. Take one serving during the day: post workout on training days, and anytime on rest days. You can also take a second serving before bed to help muscle repair and recovery while you sleep.

Classic Questions

1. I’m trying to gain muscle, so what is the best way to use Vintage Brawn™?
Have a Vintage Brawn protein shake right after your workout. You can also use Vintage Brawn as a meal replacement any other time of day, e.g. first thing in the morning (breakfast), as a mid-afternoon snack, or before bed.
2. Can I use Vintage Brawn™ on a fat-loss or cutting diet?
Absolutely. Taking it after workouts will help you preserve lean muscle and boost your metabolism. Using it as a meal replacement – especially to replace a higher-calorie meal – can help you lose fat faster. Vintage Brawn can also help you regulate your appetite: Protein tends to be satiating. Plus, the delicious taste of Vintage Brawn™ helps satisfy cravings for sweets.
3. Should I have a protein shake after cardio?
Having Vintage Brawn™ after cardio is a great way to enhance recovery. Plus, because it’s high in protein but low in carbs, it won’t cause your fat-burning metabolism to slow down, unlike what happens if you eat a meal high in carbs (especially high-GI carbs).
4. Can I use Vintage Brawn™ in recipes?
Yes. There are all kinds of protein powder recipes online. Protein puddings, cupcakes, pancakes, and so forth. Vintage Brawn™ can be used in many different recipes besides shakes and smoothies.
5. Does it have any beef or egg aftertaste?
We can happily confirm that there is absolutely NO beef or egg taste or aftertaste (nor milk for that matter). The flavor is delicious rich chocolate, made with natural Dutch cocoa. Vintage Brawn™ is possibly the best-tasting naturally flavored and naturally sweetened protein powder on the market today.
5. Is Vintage Brawn lactose free?
Vintage Brawn™ shouldn’t cause any negative side-effects for individuals who are lactose-intolerant, as their sensitivity stems from the inability to properly breakdown the SUGARS (lactose) in milk. Vintage Brawn™ contains milk protein isolate (MPI) – meaning the lactose and fat have been extracted and removed – to leave behind ONLY the two milk proteins casein and whey.
