It’s no secret that sports supplements are able to deliver a performance boost to individuals performing regular strength training and physical exercise. Nutrition is one of the most important elements of building a fit and healthy physique, but choosing the right supplement provider from the thousands of different manufacturers on the market today can be difficult.
There is a huge amount of contradictory and confusing information around which ingredients, formulas, and supplements are the most effective in boosting strength output, endurance, and muscle mass.
Many supplement manufacturers obfuscate the ingredients they use in their products or pack out their formulas with fillers or ineffective elements that don’t provide any clinically proven benefits. Finding a supplement that contains only clinically proven and effective ingredients can be a time consuming and complex process.
iSatori are an established player in the performance supplement industry that have been supplying high quality products to fitness enthusiasts worldwide since 2001. The iSatori brand has been nominated for a wide variety of industry awards such as the Bodybuilding.com best supplement award and the Marketplace Ethics award from the Better Business Bureau due to their open-handed policy and transparent, evidence-backed formulation.
iSatori have recently released an updated and refined version of their Extreme Series range of performance supplements. Consisting of a testosterone booster and a high-powered preworkout energy booster, the Extreme Series is one of the most well-respected brands in the supplement industry.
In this article, we’ll take a look at the reformulated iSatori Extreme range and break down the new ingredients to find out whether they can keep up with the latest supplement tech of 2017.
Who Are iSatori?
Founded in 2001, iSatori is one of the most trusted supplement manufacturers in the industry. Driven by a mission statement that values integrity and honesty in sports supplementation, iSatori provide a vast amount of clinical evidence to support the ingredients in their product range.
The full iSatori range consists of a broad spectrum of fat burners, muscle boosters, hormone boosters, and performance stacks that are designed to help fitness enthusiast reach their goals faster.
iSatori sponsor some of the biggest names in the strength training and fitness industry, such as Brian Shaw, Taylor Chamberlain and Mike Lee. Although iSatori have an established presence in the industry, however, it remains to be seen whether the company is content to rest on their laurels, or whether their new Extreme series is able to maintain their track record of delivering high quality, effective supplements. To find out, we’ll proceed to break down the new offerings in the Extreme range.
iSatori Rapid-Test
iSatori Rapid-Test is an updated version of their popular testosterone amplification supplement. There are many testosterone boosting supplements available on the market today, available in a range of efficacy and reliability.
The testosterone booster industry can, on occasion, be deceptive, with many supplements claiming “clinically proven” results based on in vitro trials that rely upon extremely small data sets, or extremely small increases in free testosterone levels.
The Rapid-Test formula contains a proprietary formula called Testosurge that, surprisingly, has been proven in multiple clinical trials to deliver significant testosterone gains in a short timeframe.
Often proprietary formulas are smokescreens to hide simple herbal extract complexes, but the Rapid-Test Testosurge compound has been demonstrated in at least two randomized, double-blind trials to significantly improve testosterone production.
The Rapid-Test Formula
Rapid-Test contains the unique Testosurge compound in addition to tribulus terrestris, a herbal extract that has been demonstrated in multiple clinical trials to increase testosterone production.
A widely-cited clinical meta-study performed in 2009 that assessed more than 20 different individual clinical investigations has conclusively proven that tribulus terrestris is able to dramatically increase blood serum testosterone levels with no negative side effects.
Rapid-Test also contains boron, calcium D-glutarate, and a vitamin and mineral complex that is designed to support healthy endocrine function. From the scientific evidence available, it’s clear that the Rapid-Test formula is an improvement over previous iterations of the supplement, and is one of the most effective testosterone boosters on the market.
iSatori PWR V2
The iSatori PWR supplement has long been regarded as one of the most effective and balanced preworkout supplements available, and the second iteration of the formula appears to continue this tradition.
The formula is designed to deliver a combination of strength, energy, and muscle synthesis optimization through a carefully constructed composition of both fast and slow release energy boosters.
Many of the most commonly available preworkout supplements rely on extremely high doses of caffeine to deliver the sensation of increased energy, while actually causing detrimental shakes, jitters, and potential cardiovascular complications.
The PWR V2 formula contains, in addition to a broad spectrum of muscle and power boosters, a three-phase timed release caffeine blend that ensures a regular and jitter-free energy release.
The PWR V2 Formula
The PWR V2 formula is one of the most comprehensive on the market. All of the standard preworkout ingredients, such as creatine, theacrine, beta-alanine, and Carnosyn are included, as well as a number of unique ingredients that we haven’t seen anywhere else.
One of the most interesting inclusions is elevATP, an innovative new compound that has been clinically proven to increase the efficiency with which the body is able to convert food into adenosine triphosphate, the energy currency of the body.
The PWR V2 formula also contains Bioperine, an ingredient that is typically only used in fat-burning supplements to increase the lipolysis rates of the body. In the PWR V2 formula bioperine acts as a bioavailability enhancer, increasing the total effectiveness of the formula.
The Verdict: iSatori Extreme Series
When combined together, the iSatori Extreme series is one of the most effective performance stacks on the market. Both products are designed to complement each other- the creatine in the PWR V2 stack is able to increase testosterone production of the body by up to 40%, multiplying the efficacy of the Rapid-Test ingredients.
If you’re looking for one of the most comprehensive, well-formulated, and cost-effective performance enhancing stacks available on the market, the iSatori Extreme series is one of the best options available.
