Both scientific research and real-life experience are crucial when it comes to the development of a sports nutrition or health & wellness product. While scientific research can show us what is supposed to happen with certain chemicals and compounds, actual lived experiences may yield a different result. It is one matter to breeze through clinical trials and add random ingredients at clinical doses together, it is another matter entirely to put these ingredients through rigorous testing in actual humans and determine the true applicable efficacy. When both research and experience are balanced at the right ratios, you can develop a truly effective formulation that is going to derive the best results possible. Below is a selection of our leading products, and a scientifically-backed breakdown of what makes them so effective.

What is Adabolic:

Adabolic Steel’s capstone product, providing athletes an elite peri-workout experience without reliance on stimulants or compromising on effective dosages. Adabolic optimizes aerobic and anaerobic performance, sustains endurance, supplies great pumps, and drives recovery. Because of Adabolic’s comprehensive stimulant-free formula, you can get a wide range of unique benefits, depending on the time you take it. This offers significant modularity, and truly allows the athlete to make sure they are getting the most out of this product for their needs. Adabolic can be taken pre, intra, or post workout, depending on the specific benefits desired from the athlete.

The Science Behind Adabolic:

Through the utilization of a specialized carbohydrate, Adabolic initiates a slight insulin-response to send the performance-enhancing compounds throughout the body, maximizing absorption and effectiveness. This allows for peak performance, both from Adabolic and from the athlete, ensuring that aerobic and anaerobic output are optimized. Adabolic unlocks these benefits through the utilization of insulin-positive carbohydrates, vasodilation-focused ingredients, and a suite of amino acids designed to promote endurance and recovery.

Ingredient Highlight - Glycomax Targeted-Nutrient Transportation:

Glycomax is a superior carbohydrate derived from rice and potato, that at the proper dosage can provide you with a slight insulin spike. The main purpose of Glycomax is to trigger that insulin spike and act as the transportation mechanism for the rest of the ingredients within Adabolic. Glycomax relies on more controlled insulin modulation compared to simple sugars. This reduces a potentially severe insulin crash and allows for enhanced performance, without permitting excess carbohydrates to be stored back into the body. Ideal for pumps, endurance, nutrient uptake, performance, and recovery when combined with the 30+ ingredients found in each serving of Adabolic. Full Breakdown Here:


Whatis Shredded-AF:

Shredded-AF is a multi-faceted thermogenic fat-burner that works to increase thermogenesis, suppress appetite, and supply continuous energy and mental clarity. By combining a potent stimulant profile along with sustained thermogenic compounds, Shredded-AF utilizes mechanisms of action from all angles to ensure an optimal rate of body-fat loss.

The Science Behind Shredded-AF:

Shredded leverages both stimulant and thermogenic compounds to stimulate lipolytic activity, spur hepatic oxygen consumption, encourage metabolic health, and increase core internal body temperature. By combining all of these different variables, Shredded is a critical asset for athletes seeking to mobilize stored body fat and bring in a highly-conditioned aesthetic that will bring forth muscle tissue and vascularity

Ingredient Highlight- LeanGBB & the Role of Sweat Production

Gbb, short for gamma butyro-betaine hydrochloride, is a compound responsible for the production of l-carnitine in the body. When GBB spurs l-carnitine production, this incurs a thermogenic response; opening the pores and allowing for enhanced sweat output. While the sweat output and thermogenic responses are heightened, l-carnitine transport long-chain fatty acids into the mitochondria of cells. These cells go through a process called beta-oxidation, allowing for ATP to be released, increasing cellular energy and fat loss. By using stored body fat for cellular energy, Shredded optimizes endogenous energy utilization, reducing the reliance on outside sources of energy for fuel. Full Breakdown Here:


What is Rested-AF?

Rested-AF is a comprehensive sleep performance product based upon not only improving the quality and length of sleep, but also enhancing physiological and cognitive performance the following day. The benefits only get stronger with consistent usage, and Rested-AF has been meticulously designed to allow for daily consumption without building tolerance or dependence. Rested-AF focuses on the most pivotal components of sleep: REM Sleep, brain-wave modulation, proper sleep cycle support, nervous system modulation, GH & IGF-1 secretion, as well as the reduction of physiological & mental stress.

The Science Behind Rested-AF:

As mentioned previously, Rested-AF is designed to improve sleep quality, length, and physical + mental performance the following day through various effects on sleep performance metrics.

REM Sleep

Also known as Rapid Eye Movement sleep. Composed of two phases (phasic & tonic) REM is responsible for vivid dreaming, GH and IGF-1 secretion, and memory retention. Those who achieve higher qualitative levels of REM benefit from muscular recovery, information storage, healthy cell production and cognitive function.

Brain Wave Modulation:

There are thought to be five main distinctions of brain waves: Alpha, Beta, Delta, Gamma, Theta. Each brain-wave is responsible for different effects on the body and brain. For example, Alpha Waves, which are responsible for feelings of calm and relaxation, are produced in higher quantities during the first stage of non REM sleep, and allow the individual to drift further into the sleep cycle.

Sleep Cycle Support:

A Sleep Cycle consists of going through sleep-stages (four non REM and one REM stage). On average, an individual will go through 4-5 sleep cycles per night, with a sleep cycle taking approximately 90 minutes to complete. In order to successfully complete a quality sleep cycle, botanical and amino-based compounds can work to successfully guide the brain and body throughout the different sleep stages, leading to better sleep over time.

GH and IGF-1 Secretion:

Growth Hormone and IGF-1 are coveted compounds that stimulate muscle recovery, bone and joint support, increase the utilization of stored body fat as energy, and efficient usage of nutrients consumed throughout the day. Through the increased length and quality of REM sleep and sleep cycles, GH and IGF-1 secretion can be maximized to their fullest potential.

Physiological and Mental Stress:

When under a significant amount of physiological and mental stress, the brain and body can struggle to relax, making initiating a sleep cycle more difficult. Additionally, this can lead to the production of pre-sleep cortisol, which can make muscular and cognitive recovery difficult, and may even impact hormonal status, depending on the severity. Reducing these types of stress will allow for better, and longer sleep.

Ingredient Highlight - Zylaria and Systemic GABA Utilization

Zylaria contains a unique fungi called xylaria, which has a profound effect on GABA. For reference, GABA (also known as gamma amino-butryic acid) is responsible for being a “master-key” of neurotransmitter inhibition. Through this mechanism, GABA allows for the reduction of sporadic neurotransmitter spikes, which grants a significant reduction of many variables that play into the production of stress and anxiety. Xylaria, triggers increased GABA while modulating GABA-transaminase & glutamate decarboxylase activity to promote stronger GABA concentrations and activity. Full Rested-AF Breakdown here:


What Is Alpha-AF:

Alpha-AF is a natural hormonal optimization product designed for men. There are numerous hormone-disrupting variables men face each day: from microplastics in drinking water and the food supply, to xenoestrogens on receipts, even to the prevalence of seed-oils in 95% of packaged food and restaurant kitchens, it can be extremely challenging for men to realize their natural hormonal potential. When a man's T is interrupted, or his E is not in sync with T, physical performance and psychological performance suffer. It can be harder to gain muscle, lose weight, or even have the daily motivation to perform tasks. Alpha-AF optimizes natural hormonal output, supporting ideal T to E ratios, allowing for better whole-body recovery while increasing athletic drive, libido and aggressiveness.

The Science Behind Alpha-AF

In order to optimize T, there are certain factors that need to be accounted for: body fat mobilization, stress adaptation, sleep quality, E control, and consistent saturation of T supporting compounds.
Body Fat Mobilization: One of the most efficient ways to spur body fat mobilization is to accrue additional muscle tissue. Muscle tissue is highly energy-intensive to preserve, recover, and grow. Alpha-AF can help optimize a man's ability to initiate muscle growth by promoting consistent athletic performance, providing a muscle-building foundation that can be taken additional advantage of by incorporating a healthy diet and proper sleep protocol.

Stress Adaptation:

When high levels of stress are left unmanaged, a stress hormone known as cortisol can accumulate in levels that make muscle recovery and cognitive improvements more difficult. Adaptogenic compounds such as Safed Musli can initiate responses in the body that allow for the reduction of cortisol at unwanted times. Cortisol is crucial to recovery at lower amounts, so complete elimination is unwanted. When cortisol is managed properly, serum levels of T have been shown to increase in men.

E Control:

Often misunderstood, E in the right amounts compared to T is essential to a healthy hormonal response in men. E levels which are too high or low can lead to unwanted shifts in emotional state, lower physical performance, decrease in strength, adverse changes in sense of wellbeing, and flat muscular appearance. When E is controlled and kept in a healthy reference range compared to T levels, these effects can be avoided.

T Saturation:

Because your endocrine system is a 24 hour operation, consistent saturation of compounds that support healthy T production are crucial to regular hormonal outputs. Alpha-AF is designed to provide higher plasma levels of T, modulate E expression, and promote an ideal hormonal profile around the clock
