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

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.

Dutch Cocoa Powder¹

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

¹ Wicked Chocolate and Chocolate Coconut flavors only.

Other Ingredients

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

Monk Fruit Extract

Frequently Asked Questions

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.

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.

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.

Should I take Classic Creatine before or after my workouts?

You can take Classic Creatine before or after your workouts, whichever you prefer. For maximum results, take it right after eating a carbohydrate-containing meal or snack and with 10-12 oz of water.

Should I cycle creatine?

Great question. Despite all the attention this subject gets, when it comes to creatine, there’s no anecdotal nor scientific proof that “cycling” (i.e. taking a periodic break from a supplement before resuming its use) offers any benefits, or has any downsides, for that matter. There’s also no evidence to date that there’s any harm in taking a maintenance dose (e.g. 3-5 g) of creatine every day without a break.
