1289 reviews

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.

• Made of protein isolates with zero additives

• For athletes and bodybuilders of all fitness levels

• Lactose-free, zero sugar, easy to mix and digest

Eggs, milik & beef. Protein your body actually uses.


These days, chances are if you’re using a protein powder, it’s whey protein. Whey has become the protein choice for everyone, from kids to grandparents. A byproduct of cheese production, whey is particularly prized for its absorption speed. It’s a good protein, but it’s not the most effective way to build muscle, nor to reduce muscle loss. Yet, we’ve been told over and over again that whey is the only protein we need to achieve our goals. 

For us at Old School Labs™, that just doesn’t make sense!

Golden Era athletes relied on eggs, milk, and beef – the Big Three – to build high quality muscle. Today, science is catching up with what these athletes knew all along: that the combined proteins of the Big Three surpass the muscle-building and muscle-preserving properties of whey, or any single source. Why? Because together they deliver a synergistic muscle-building effect that’s more powerful – it kicks in fast and lasts for hours.

Vintage Brawn™ is the first supplement to successfully combine the highest quality isolates of these three prized proteins. Which means you get all the muscle-building power without the extra fat, sugar, or cholesterol – in an incredibly tasty protein powder.

Vintage Brawn Vanilla Milkshake

I usually get chocolate protein, but I tried a sample of the vanilla and it was very good! I like the flavor by itself, but it’s just as good with some strawberries and bananas!

Chocolate Mint/ great combo

The chocolate taste is good but the added mint flavor makes it even better. The favorite part of my workout is drinking this when I’m done.

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.

What is the sugar / carb / calorie content of this product?

Vintage Blast™ contains no carbs, no sugars, and no calories. The sweetening in Vintage Blast™ is provided by stevia leaf extract, a natural sweetener with zero calories and zero carbs.

Can you use the pre-workout and the fat burner at the same time?

Yes. You can stack Vintage Blast™ with Vintage Burn™, and many of our customers do exactly that to enjoy the combined benefits. You can start by taking a half-dose of Vintage Burn™ (1 capsule) with Vintage Blast™ and then move up to the regular dosage.

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).

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.

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.

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.
