    All the Amino Acids Needed to Build Muscle

    Vintage Bolt gives you all of the amino acids that are essential for building muscle and every other tissue in your body. High levels of amino acids in the body in the body promote muscle-building protein synthesis.

    EAAs to Build Muscle
    Fast-Burning MCT Oil Fuel

    Unlike Long-Chain Triglycerides, Medium-Chain Triglycerides (MCTs) are burned quickly rather than stored as fat. Vintage Bolt uses MCTSmart®, which is a premium source of MCTs. It promotes the formation of ketones, and helps fuel your workouts.

    Electrolytes and pH Buffers

    Electrolytes and pH buffers help your muscles push hard and fight through the burn (accumulation of acid, H). By helping your muscles clear away H, you extend your sets and get more “time under tension” - essential for maximizing muscle gains.

    Why It Makes Sense

    Vintage Bolt is part of our Muscle & Strength supplements range. We created it because achieving a balanced, head-turning musculature should never come at the expense of your health.

    A Good Start

    An intra-workout supplement can help you build muscle and increase energy and endurance while you train. Most intra-workout products contain Branched-Chain Amino Acids (BCAAs) to achieve that. It's a good start. But it’s only a start.

    In fact, if you take only BCAAs during your workout, there’s a really good chance that some, if not most, will be burned as fuel instead of being used to build muscle. So, you end up with more energy to work out but not much left for protein synthesis (muscle building).

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

    The Complete Solution

    Unlike other intra-workout supplements, Vintage Bolt has all of the ingredients you need to have a complete muscle-building workout. It contains every Essential Amino Acid (EAA) that is key for building muscle and every other tissue in your body.

    Moreover, Vintage Bolt contains MCT Oil which your body burns as fuel rather than stores as fat. And, it burns quickly. You don’t need to wait around for it to affect your performance. This also spares the amino acids from being burned. Better still, Vintage Bolt has electrolytes and pH buffers. They help you push harder and fight through the burn (accumulation of acid). This means more “time under tension” - which is essential for maximizing muscle gains.

    In short, Vintage Bolt contains all the essential building blocks your body needs for muscle growth, plus the required energy to do it without wasting any of them.

    Supplement Facts

    Main 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. Few companies can say that they hand-pick each of their ingredients, carefully and patiently waiting for that ingredient’s prime season of maximum potency; harvesting and processing each ingredient carefully to ensure that only the most premium and bio-available ingredients make the cut into their products.

    At Old School Labs™, we set out from the start to be a premium and uncompromising brand, delivering exclusively premium products. We sell our products directly to you and are therefore able to afford including only the best quality ingredients in all our products. Press More to read about the ingredients you will find in Vintage Bolt™:

    Electrolytes and pH Buffers:

    Calcium Lactate, Magnesium Citrate, Sodium Citrate, and Potassium Bicarbonate: In addition to supplying electrolytes that are essential for proper muscle function (i.e. calcium, magnesium, sodium and potassium), these ingredients serve as buffers that help your body keep pH in a range that’s optimal for peak muscular performance.

    Muscle Support and Energy Group:

    MCT SMART® Vegan C8

    Made in the USA from coconut and palm fruit, MCT SMART® is 100% vegan and contains Medium-Chain Triglycerides (MCT) oil. MCTs are a healthy type of fat that can be converted into energy quickly. They also boost ketone production, support cognitive (brain) performance and may enhance fat loss.

    Essential Amino Acids (EAAs)

    They are essential for building muscle and every other tissue in your body. L-leucine, L-isoleucine and L-valine comprise the Branched-Chain Amino Acids (BCAAs) and are very important for muscle function. L-tryptophan, not commonly found in regular intra-workouts, is required for the synthesis of Niacin and Serotonin. L-lysine and L-methionine are required for the synthesis of carnitine. Carnitine helps your body burn fat. Lysine is also a key building block of collagen.

    Other Ingredients:

    The other ingredients section on supplement labels has unfortunately become a convenient place for some companies to hide their sub-par ingredients, fillers and additives in plain sight. This is where you will commonly find the usual cost-cutting and unnatural ingredients that do nothing to help your health - ingredients such as sucralose, aspartame, gelatin, artificial flavors and colors, and a plethora of cryptic chemical substances that really don't have their place in your body if you want what is best for it.

    At Old School Labs™, we treat the other ingredients with the same care as our main dietary active ingredients. Therefore, they are carefully and selectively sourced, and included to serve a specific purpose. To our knowledge, we are the only company that goes beyond simply listing our other ingredients on the label (as required by law), and to also explain each of them so that you know what you are putting into your body. Here are the other ingredients you will find in Vintage Bolt™:

    Citric Acid

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

    Natural Flavors

    We use a combination of natural flavors to create a refreshingly delicious taste.

    Beet Root

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


    Steviol glycosides are a natural sweetener obtained from the leaves of the Stevia plant.

    Rice Hulls

    They are rich in silica, which serves as a flow agent. A flow agent is something that helps ingredients flow more easily, making them less prone to clumping.

    Beta Carotene

    A natural, organic, pigment found in carrots and other plants. It is also a precursor to Vitamin A.



    For use as a dietary supplement for men and women. Mix 1 scoop of Vintage Bolt™ with at least 16 oz of cold water and drink during your workout. For great mixing results, try the OSL Nalgene® Gym Water Bottle.



    This product was produced in a cGMP facility that also processes ingredients containing milk, egg, soybeans, shellfish, fish, tree nuts, and peanuts.

    1. What are EAAs and how are they different from BCAAs?

      Branch-Chained Amino Acids (BCAAs) are actually part of the Essential Amino Acids (EAAs). They are called essential because your body cannot make them, and you can only get them from food and/or supplements. They are the building blocks of all the tissues in the body – including your muscles.

    2. Does Vintage Bolt contain caffeine?

      Some intra-workout products are caffeinated to make them feel like they are “working.” Vintage Bolt contains no caffeine or other central-nervous system (CNS) stimulants.

    3. I’m already taking a pre-workout supplement, do I really need an intra-workout?

      Great question. If you’re a hard gainer or just really serious about gaining muscle, then taking both a pre-workout and an intra-workout can give you an edge. Normally, a pre-workout like Vintage Blast is used to boost your energy and mental performance and help you get big pumps. Whereas, Vintage Bolt helps top off your fuel “tanks” so you can go the distance and provides essential amino acids to maximize muscle anabolism.

    4. I workout in the evening and therefore don’t want to take a caffeinated pre-workout supplement. Can I use Vintage Bolt as a pre-workout?

      Sure. Because it contains no caffeine or other CNS stimulants, Vintage Bolt won’t disrupt your sleep. Simply take 1 serving before you workout. If you are training for more than 90 minutes, you can take another ½ to 1 serving half-way through your workout, if desired.

    5. Is Vintage Bolt just for people who lift weights?

      No. Vintage Bolt can benefit any type of workout, whether you’re running, lifting, climbing, jumping, spinning or otherwise. Every form of exercise requires a source of fuel and your muscles are always using the essential amino acids. Vintage Bolt provides both.

    6. Do I need to cycle my use of Vintage Bolt?

      No. You can continue to use Vintage Bolt for as long as you like. However, it’s not a bad idea to switch up your supplement routine from time to time. We have many different products you can switch back and forth between, and stack them as you like.
