Product Overview

Carbon by Layne Norton Carbon by Layne Norton PREP. PREP. Advanced Pre Workout Formula.
Layne Norton

As a scientist, champion natural bodybuilder, raw elite powerlifter, and physique architect, I saw a need for well-formulated supplements that smart lifters could trust. CARBON supplements are tools for those who train hard, eat smart, and care about what they put in their bodies.

Many pre-workouts are long on promises, ingredients, and claims but short on results. Carbon Prep is the opposite. It's not a proprietary blend. It's not sprinkled with unfamiliar ingredients or walled behind bogus claims. There is no product "dusting." Everything is scientifically dosed to bring you results based on clinical research.*

Carbon Prep doesn't have any "throwaway" ingredients that seem trendy, but are backed by very little research--and included only to make a product appear novel. Novelty for the sake of novelty is nonsense. Novelty is only valuable if an ingredient is also effective.

Carbon Prep contains only nine ingredients, but each is included for a specific purpose in the proper dose.* Carbon Prep is also formulated to work synergistically with Carbon Post. Both work well as standalone products, but they work even better together because of their complementary ingredients.

THE BENEFITS OF
CARBON PREP
  • Increase lean body mass*
  • Reduce excessive muscle damage*
  • Increase blood flow and nitric oxide production, leading to a better pump and more nutrients to your muscles*
  • Modestly increase fat oxidation*
  • Improve subjective feelings of well-being, potentially allowing you to train harder*

The number one goal of Carbon Prep is to help you have more effective workouts--not just once, but every day. Increased consistent performance translates to more PRs, more reps, and more volume, so you can build more muscle over time. Carbon Prep contains ingredients that have been demonstrated to decrease fatigue during anaerobic and aerobic exercise as well as increase power output and strength.

In addition to physical performance, Carbon Prep enhances your mental performance. It improves your focus and cognitive function without the use of added stimulants so you can take it day in, day out without relying on large amounts of caffeine and other stimulants to perform optimally.* This also makes Carbon Prep great for people who work out in the evening, want to use a pre-workout to enhance their performance, but want to be able to sleep well afterwards.

THE ELEMENTS OF
CARBON PREP
CITRULLINE MALATE

Citrulline malate is found in many pre-workouts in low doses. Carbon Prep contains a full dose of 6 g, because that's what the research demonstrating improvements in performance and fatigue-resistance calls for.1,2
L-citrulline is an amino acid that, when metabolized, turns into L-arginine. However, supplementing with citrulline is actually more effective than supplementing with arginine itself because, when ingested, citrulline does not undergo the same rate of liver metabolism that arginine does, making it more available in the body.3 This means it delivers a stronger performance result. The bottom line: Not only does citrulline malate improve fatigue resistance during aerobic and anaerobic exercise, it can also decrease soreness, increase muscle protein synthesis, and lean body mass.4-8

CREATINE MONOHYDRATE

The benefits of creatine are well-documented. It increases lean body mass, strength, performance, and phosphocreatine--an energy source--stores in muscle.9-11 The debate is what form of creatine is best. While many companies attempt to reinvent the wheel with new forms of creatine so they can charge you a premium, the overwhelming majority of research showing the benefits of creatine supplementation has been performed with creatine monohydrate. While some other forms may be as effective as creatine monohydrate, no other form has been demonstrated to be more effective than creatine monohydrate. Since creatine monohydrate is also less expensive than all other forms, Carbon Prep uses it to ensure you don't spend an unnecessary amount of money.

BETAPOWER®
BETAINE ANHYDROUS

Betaine is a new and exciting supplement. Betaine supplementation has been demonstrated to improve performance and power output, and it may increase lean body mass.12,13 Carbon Prep delivers a full 2.5 g dose of betaine to ensure optimal results at a research-supported dose. Beyond that, the trademarked BetaPower Betaine Anhydrous is the only betaine patented for exercise performance. It is also backed by peer-reviewed publications demonstrating sports-performance benefits.

Astragalusmembranaceus

This herbal extract has a long history of use in traditional Chinese medicine. Today, studies suggest that when combined with exercise, astragalus membranaceus may result in enhanced endurance capacity and reduced negative byproducts associated with strenuous exercise such as blood lactate and ammonia. It has also been shown to have beneficial effects on inflammation and the immune system.14, 15

Carnipure® L-Carnitine L-Tartrate

L-Carnitine L-Tartrate (LCLT) is the form of carnitine typically used in research studies that demonstrate benefits from carnitine supplementation. Carnitine has been shown to improve workout performance by decreasing fatigue and blood lactate and slightly increasing power output.16, 17 LCLT may also decrease delayed onset muscle soreness and increase androgen receptor density in muscle cells.18, 19 More androgen receptors in muscle cells may mean that your current levels of anabolic hormones like testosterone may work more efficiently and your body can respond more appropriately to these hormones. Androgens like testosterone contribute to muscle growth by stimulating myogenesis, the formulation of muscular tissue. Further, LCLT may also increase blood flow to deliver oxygen and nutrients to hard-working muscles.20

Cocoa Powder

Cocoa is one of the more reliable supplements on the market for increasing blood flow, even in healthy people.21, 22 Many supplements note an effect in populations with compromised blood flow by using other ingredients, but few show difference in healthy individuals. 23 Although the benefits of cocoa are well known, the mechanism by which the cocoa flavanols work is still being researched. Currently, it is believed to work in multiple ways, including activation of nitric oxide as an antioxidant and supports a healthy inflammation response.

Alpha-GlycerolPhosphoryl Choline

Alpha-GPC is a choline-containing phospholipid, used to make acetylcholine (a neurotransmitter) and phosphatidylcholine in the brain. Acetylcholine is vital for cognitive function and the communication between neurons.

Rhodiola RoseaExtract

Rhodiola Rosea may be one of the most underrated pre-workout ingredients. There is very strong evidence that it decreases fatigue even at a relatively low dose.25 It also improves cognition and decreases the rate of perceived exertion.26 Finally, it has been demonstrated to decrease muscle damage.* 27 This means you can train harder, longer, and recover faster. Carbon Prep delivers a full dose to bring you all the benefits.

Huperzine A

Huperzine A has been demonstrated in research studies to improve cognition, memory, and task learning.28-30 Its activity leads to acetylcholine accumulation and hyperstimulation of the receptors. As a neurotransmitter, acetylcholine transmits signals from one cell to another, allowing communication. This provides many benefits to the autonomic, peripheral and central nervous systems, which control the body and communication of its parts.

Carbon Prep
CARBON: FOUNDED ON QUALITY AND RESEARCH

When I founded Carbon, my goal was to provide high quality supplements that were clinically dosed with effective ingredients*. I also insisted that they were not ‘over marketed.’ I am not willing to bend the truth to sell more supplements, I simply will not do it. In line with this mission was to ensure that not only were the ingredients in Carbon products properly dosed, but they used manufacturers that could ensure quality and actually back up their ingredients by contributing to clinical research*. Many times manufacturers will use cheaper versions of ingredients that aren’t backed by research in order to increase their profit margins at the expense of effectiveness.

A great example of this is using Carnipure as the source of l-carnitine. Other forms of carnitine are very popular in supplements, but usually that is because they are less expensive to incorporate. L-Carnitine L-Tartrate found in carnipure however is the only form of carnitine demonstrated to support recovery, decrease muscle soreness, support performance, and increase androgen receptor density in muscle cells*. Is it more expensive than some other forms of Carnitine? Yes. Could we ‘get by’ on some of our claims using other forms of carnitine that were not used in clinical research? Absolutely. Would we feel good about it? Absolutely not. That’s why in every Carbon product you will only find the highest quality, clinically backed ingredients, so that you can be sure that you are getting the most effective, science based, products on the market*.

YOUR BEST WORKOUT, BOTTLED

Carbon Prep is designed to give you better workouts that are consistently repeatable. Most pre-workouts rely on a hefty dose of stimulants to mask under-dosed ingredients. While your performance may improve in the short-term with these weak blends, the long-term viability of maintaining workouts at that level is very low.

With Carbon Prep, I have created a performance enhancing pre-workout that works independently of added stimulants to help deliver optimal workout performance and focus that is maintainable and replicable*. Train harder, train longer, train more effectively, and recover faster.* That's the promise of Carbon Prep, but it only works if you do.

Very good, not great, NON-stim preworkout. I typically drink about 1/2 pre and the rest intra-workout. Good taste. Big dose of citrulline, all the other basic pre/intra workout ingredients. I like Nutrabio's Stim-free better. And I like Kaged Muscle In-Kaged better. But this is a good product at a great (sale) price; sad to hear it is being discontinued.

the flavor (Fruit punch) is really good and does the job of not tasting like crap. The effects are great as well.. I have a sensitivity to caffeine and this stim-free pre did exactly what I thought it would do. it gave me a great amount of pump and sustainable energy throughout my workout.... My only con is that i wish it had other forms of energy because even though it gave me sustainable energy, it wasn't enough to power through a high intensity training session...... it was really good for a basic low/mid intensity workout. so imo i would add some other forms of energy if you are sensitive to caffeine like myself or even add in a very minimal amount of caffeine to help with the boost.. it doesn't take much to get jolted with this stuff. HIGHLY RECOMMENDED!

I cannot use caffeine at all, at any time of day. This prep helps me focus on and power through my weight routines, better than those days I worked out without it. I am recently coming back to lifting from a layoff and my first panicked thought was Carbon had stopped producing this stimulant-free prep. A relief to find I can still get it.

Great taste and dissolves quickly! However, one scoop didn't give me that drive or boost to do more.
