This high-stim pre-workout is designed to enhance exercise performance and promote muscle growth. With its unique blend of ingredients, including Citrulline Silicate, 2-aminoisoheptane HCL, taurine, and L-arginine, Krank3D aims to push the boundaries of nitric oxide production and provide users with intense workouts and improved results.

In this article, we will delve into the science behind Krank3D and explore the benefits of its key ingredients. We will also discuss the potential risks and side effects associated with its use. So, if you're curious about whether Krank3D is the right pre-workout supplement for you, keep reading to find out more.

The Science of Nitric Oxide Production

Before we dive into the specifics of Krank3D, let's first understand the role of nitric oxide (NO) in the body. Nitric oxide is a naturally occurring molecule that plays a crucial role in regulating blood flow and vasodilation. It is produced by the endothelial cells lining the blood vessels when the amino acid L-arginine is converted into NO through the action of the enzyme nitric oxide synthase (NOS).

Increased levels of NO lead to vasodilation, which widens the blood vessels and improves blood flow. This enhanced blood flow is sought after by bodybuilders and athletes as it can optimize the exchange of oxygen, glucose, amino acids, and other nutrients during and after intense workouts.

Understanding Krank3D's Key Ingredients

Krank3D stands out from other pre-workout supplements due to its unique blend of ingredients, including Citrulline Silicate, 2-aminoisoheptane HCL, taurine, and L-arginine. Let's take a closer look at each of these components and their potential benefits.

Citrulline Silicate

One of the primary ingredients in Krank3D is Citrulline Silicate, specifically a proprietary compound known as Nitro Rx. Citrulline Silicate is a combination of the amino acid citrulline and silicate, which is believed to enhance the bioavailability and effectiveness of citrulline.

Citrulline is a precursor to L-arginine, meaning it is converted into L-arginine in the body. By increasing the levels of L-arginine, Citrulline Silicate promotes nitric oxide production and improves blood flow. This, in turn, can enhance exercise performance, increase muscle pump, and support muscle growth. (2)

2-aminoisoheptane HCL

Another key ingredient in Krank3D is 2-aminoisoheptane HCL, also known as octodrine. This compound is a stimulant that acts on the central nervous system, providing users with increased energy, focus, and alertness during workouts.

2-aminoisoheptane HCL is believed to have similar effects to other stimulants, such as caffeine, but with a smoother energy boost and reduced crash afterward. It can help users push through intense workouts, improve endurance, and maximize their training performance. (1)


Taurine is a naturally occurring amino acid found in various tissues throughout the body, including the muscles and the brain. It plays a role in numerous physiological processes, including muscle contraction, antioxidant defense, and regulation of cellular electrolyte balance.

In the context of pre-workout supplementation, taurine is believed to support exercise performance and reduce exercise-induced oxidative stress. Research has shown that taurine supplementation can attenuate DNA damage caused by intense exercise and enhance the capacity for exercise due to its cellular protective properties. (3)


L-arginine is an essential amino acid that serves as a precursor for nitric oxide production. It plays a crucial role in promoting vasodilation, improving blood flow, and enhancing nutrient delivery to the muscles.

Supplementing with L-arginine can increase the availability of this amino acid, leading to higher levels of nitric oxide and improved exercise performance. It is also believed to support muscle growth and aid in post-workout recovery. (4)

The Benefits of Krank3D

By combining the power of Citrulline Silicate, 2-aminoisoheptane HCL, taurine, and L-arginine, Krank3D aims to provide users with several benefits, including:

  1. Enhanced Nitric Oxide Production: Krank3D's ingredients work synergistically to promote nitric oxide production, leading to improved blood flow and vasodilation. This can result in increased muscle pumps and better nutrient delivery to the muscles.

  2. Increased Energy and Focus: The inclusion of 2-aminoisoheptane HCL in Krank3D provides users with an energy boost and improved focus during workouts. This can help increase training intensity and maximize performance.

  3. Reduced Exercise-Induced Oxidative Stress: Taurine supplementation has been shown to attenuate DNA damage caused by intense exercise and reduce exercise-induced oxidative stress. This can potentially enhance recovery and reduce muscle damage.

  4. Improved Exercise Performance: The combination of key ingredients in Krank3D, such as Citrulline Silicate and L-arginine, can improve exercise performance by increasing blood flow, enhancing endurance, and supporting muscle growth.

Potential Risks and Side Effects

While Krank3D offers various benefits, it is essential to consider potential risks and side effects. As with any pre-workout supplement, individual responses may vary, and it is crucial to follow the recommended dosage and consult with a healthcare professional before use.

Some potential side effects associated with pre-workout supplements include increased heart rate, elevated blood pressure, gastrointestinal discomfort, and difficulty sleeping. Additionally, stimulants like 2-aminoisoheptane HCL may lead to jitters, anxiety, or a crash after the effects wear off.

It is also important to note that the claims made by the manufacturer about the effectiveness of Krank3D have not been evaluated by the Food and Drug Administration (FDA). As such, it is always advisable to do thorough research and exercise caution when considering pre-workout supplementation.


Krank3D by Hi Tech is a pre-workout supplement that aims to enhance exercise performance, promote nitric oxide production, and support muscle growth. With its unique blend of ingredients, including Citrulline Silicate, 2-aminoisoheptane HCL, taurine, and L-arginine, Krank3D offers users the potential for increased energy, improved focus, and better muscle pumps.

However, it is important to remember that individual responses may vary, and it is crucial to follow the recommended dosage and consult with a healthcare professional before starting any new supplement regimen. Additionally, the potential risks and side effects associated with pre-workout supplements should be taken into consideration.

In conclusion, Krank3D may be a suitable option for individuals looking to optimize their workouts and enhance exercise performance, but it is always advisable to make informed decisions based on personal health goals and professional guidance.
