PSI by EHPlabs is a non-stimulant pre-workout making it the perfect supplement if you like to train later in the day, or if you are sensitive to stimulants. PSI was developed using ingredients that work synergistically to boost your focus and performance, including: 

Citrulline Malate

In the human body, increases in circulation naturally brings greater amounts of nutrients (fuel) and oxygen to working muscles, while also providing greater waste disposal, including the lactic acid removal (you know, the burning pain we all get when he hit the gym, run or ride). The combined effects of greater circulation leads to vast improvements in muscle strength and power, while reducing muscle soreness. This results in us being able to train harder, perform better, while reducing the muscle soreness that halts our training in its tracks. There is a chemical that resides within our blood vesicles which allow the wall of the blood vessels to relax and thus increases the circulation. This amazing chemical is known as nitric oxide.

L-Arginine Alpha-Ketoglutarate

Arginine alpha-ketoglutarate (AAKG) is a dietary supplement used by athletes and bodybuilders to improve sports performance, reduce muscle fatigue, and enhance recovery. Alpha-ketoglutarate also regulates amino acid synthesis, energy production, and formation of free radicals. It functions as a messenger molecule in many chemical reactions in the body.

Agmatine Sulfate

Agmatine is a compound naturally produced within the body that plays a key role in a range of bodily processes. It reduces pain and depression and protects the heart and brain. It is a neurotransmitter found predominantly in neurons. Because it is capable of targeting multiple receptors, agmatine may benefit a spectrum of complex diseases, including diabetes, Alzheimer’s disease, opioid addiction, mood disorders, and even cancer. Furthermore, agmatine may enhance cognitive function, stress resiliency, mood, and athletic performance.


Taurine is a type of amino acid found throughout the body. It is particularly concentrated in the brain, eyes, heart and muscles. Unlike most other amino acids, it is not used to build proteins in the body. It is classified as a "conditionally essential" amino acid. Taurine has been shown to have several health benefits, such as a lower risk of disease and improved sports performance.


Tyrosine is a popular dietary supplement used to improve alertness, attention and focus. It produces important brain chemicals that help nerve cells communicate and may even regulate mood. It is an amino acid involved in various processes with the brain, to help improve mental alertness and reduce stress.


When your body starts to produce nitric oxide through arginine, it also creates an enzyme, arginase, which puts a limit on the amount of nitric oxide you can make. This effectively creates a “ceiling” on how big of a pump you can achieve. L-norvaline works by inhibiting arginase production, allowing you to blow past that ceiling and keep producing nitric oxide throughout your workout. This makes your pumps stronger and longer lasting.

Beet Root Powder

Beetroot powder is made from the beetroot vegetable. It is simply beetroot in powder form. Beetroot and beetroot leaves are full of Vitamins A, B6 and C, magnesium, iron, folate, potassium, iron, calcium, proteins, and soluble fiber. Beetroot is loaded with disease-fighting antioxidants. Most of the calories in beetroot come from natural sugars. Compared to most foods that people eat, I would not and do not worry about the sugar content from beets. It is trivial.
