Why It Makes Sense
Why It Makes Sense

Who is Classic BCAA ideal for?

Classic BCAA can be used by anyone who is striving to build or preserve lean muscle or enhance their ability to recover from workouts. It is especially helpful for so-called “hard gainers” (i.e. individuals who have an especially hard time gaining and/or retaining muscle), athletes who are in a heavy period of training (e.g. prolonged or twice-a-day workouts), and anyone who is on a carbohydrate- or calorie-restricted diet (e.g. keto) in which case there is an increased risk of losing lean muscle.

Other tips that will help you get awesome results:

The dose makes the difference. That’s why we recommend taking at least 1, and even better, 2 servings, of Classic BCAA 2:1:1 at a time. Besides paying attention to dosage, it’s important that you be consistent in your use of BCAAs. When we talk about building or preserving muscle, or increasing muscle size, we’re ultimately talking about increasing muscle protein synthesis.

This process, i.e. the building of protein by your muscle cells, is the most essential element of building muscle tissue. Occasional bursts, or spikes, in muscle protein synthesis won’t produce bigger muscles. You have to produce them several times a day, every day. Classic BCAA makes it easier. Just pop the capsules in your mouth with water, and you’re good to go.

One more tip: Choose 2 times of day to take your BCAAs. It could be before and after workouts, upon waking up and before bed, etc. Stick to it, and eventually it will become a habit that does good things for your physique and performance.


There are essentially two ways to supplement with Classic BCAA:

Method 1: Take them in between meals. Most meals contain at least some protein, which means they contain at least some BCAAs. Thus, after eating a protein-containing meal, your blood BCAA level rises, as does muscle protein synthesis. This is good news from a muscle-building standpoint. Eventually, however, your blood BCAA level starts to fall, as does muscle protein synthesis. The idea behind supplementing with BCAAs in between meals is to prevent this. Over time, this is believed to encourage greater gains in lean muscle and enhance recovery.

Method 2: Take them with meals. The idea behind taking BCAAs with a meal is to “maximize” muscle protein synthesis, just in case the meal itself wasn’t enough (i.e. it didn’t contain enough BCAAs) to do so.

Which method is best, 1 or 2? Both can work, we think Method 1 makes the most sense.


  1. I get BCAAs from my protein powder, so do I really need to take a separate BCAA supplement?

    Great question. If you’re already taking a protein powder -hopefully it’s Vintage Brawn™!- the best time to do so is immediately after you lift weights. (Vintage Brawn™ is unique in that it can also be used a meal replacement at other times of day, such as breakfast or before bed.)

    Having a protein shake after you lift weights helps stimulate muscle protein synthesis, and thereby promote muscle growth and recovery. While a BCAA supplement like Classic BCAA provides similar benefits, it is better suited for use in between meals, when muscle protein synthesis tends to be the lowest. Using Classic BCAA like this will help smooth out the ebb and flow of muscle growth, resulting in better gains over the long term.

  2. I’m trying to cut up [i.e. lose fat, increase muscle definition]. Will Classic BCAA help?

    To get cut up, or “shredded”, first and foremost you need to reduce your body fat. (We all have some!) This usually requires that you reduce your caloric intake, whether by eating fewer carbs in particular (e.g. as with a diet like keto) or eating fewer calories across the board (e.g. as by eating smaller portions).

    Any time you lose body fat on a calorie-reduced diet, you’re almost certain to lose muscle alongside. Taking Classic BCAA and a high-quality protein like Vintage Brawn™ will help you protect, and even enhance, your lean muscle while you melt off the fat on top.

  3. If I just do cardio, is there any point in me taking BCAAs?

    Yes. Taking BCAAs before and/or after cardio can help preserve lean muscle and enhance recovery. Keep in mind that if you’re looking to actually gain muscle, then you’ll need to be doing plenty of resistance exercise, i.e. lifting weights.

    It’s worth pointing out here that many people increase their cardio when they are trying to get cut up. At the same time, they are typically eating fewer calories. This can create a “perfect storm” for muscle loss. It’s not something to be alarmed about –we’re not talking about major muscle losses here! On the other hand, muscle isn’t easy to come by, so every bit counts. Supplementing Classic BCAA under these circumstances can be thought of as an insurance plan against such losses.
