The Ingredients

Not all supplement ingredients that go by the same name are created to be equally as effective. Just as there are different qualities of the same cut of meat, there are different qualities for the same supplement ingredients.




nothing artificial



FDA certified
Manufactured in USA

Main Ingredients

Branched Chain Amino Acids (BCAAs)

Isoleucine, Leucine and Valine are the most important of the essential amino acids and are absorbed directly into the muscle tissues. They are metabolized quickly to stimulate and support muscle protein synthesis and drive quality muscular development.

Creatine Monohydrate

This is the gold standard of creatine and increases strength as well as explosive endurance by acting as an energy reserve to fuel muscular performance and development.


An amino acid that is conditionally essential when training at high intensity, it plays a central role in maintaining a positive nitrogen balance and an anabolic state by reducing muscle breakdown and supporting cells. Additionally, it acts as a muscle protector when on a fat-loss regimen.

Other Ingredients

Stevia leaf extract is a natural sweetener that contains no calories. A minimal amount of high quality stevia is used to remove the bitterness and acidity naturally occurring in BCAAs & L-Glutamine.

Natural Flavors

Only natural flavors go into our refreshingly crisp tastes. Countless iterations of taste-testing allowed us to arrive to a flavor, which in addition to being natural, tastes grea.

Citric Acid

Naturally occurring acid found in fruits (notably citrus fruits such as oranges). We use it to bring out the natural flavor.

Sodium Chloride

Salt to help bring out the flavor.

Silicon Dioxide

This vegetarian-friendly compound, naturally found in many foods, is used to help prevent clumping.

Beet Juice and Powder (Fresh Berries flavor only)

We use this natural super vegetable to give Vintage Build™ a distinctive color.

Malic Acid (Lemon Lime flavor only)

Also known as apple acid (from Latin mālum / apple), it is found in apples and gives them their sour taste. In Vintage Build™, it is used to bring out the natural berry flavors.

Natural Green Color (Lemon Lime flavor only)

None of that artificial stuff.

Turmeric and Annatto (Lemon Lime flavor only)

Also used to give Vintage Build™ its distinctive color.

+ What Sets It Apart

Good nutrition and a proper training regimen are key to building muscle. Muscle-builders can help you maximize your results with higher amounts of essential amino acids (your body’s building blocks) and nutrients that are not always practical to get from food alone.

However, most come loaded with carbs, simple sugars or exotic ingredients that increase your caloric intake and water retention. They will increase your body weight, but those ‘gains’ will be mainly water and bulk. Moreover, their effects fade once you stop taking them.

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

When it comes to building balanced and aesthetic muscularity, the Golden Era bodybuilders did it right. They did not fool around with fad ingredients, relying instead on what was tried, tested, and true. Vintage Build™ carries on this philosophy in what has become a fundamental trio of ingredients for natural bodybuilders and athletes wishing to build hard, quality, lasting muscle – not useless bulk.

Just what you need. No more, no less. Too much creatine? Half scoop it. Spread it out. It's all good, this is a friend who you let come over and hang out in your living room. He cleans the dishes sometimes. He's got your back.

Works great!

I’ve been using this for about 2 weeks now, I feel great after using and I’m not as tired as I was before, the taste is a little odd, but that is to be expected.

Excellent products!!!

I have tried many products on the market, as a retired competitor I am very selective what I put into my body. Years ago when finally companies started to pay attention for reducing the amount of artificial ingredients in their products, I started to use those instead of the ones with those unnecessary ingredients. This company helped to get into one of my best shape in my life when I went back to compete at age of 42!
