ISA-Test GF by iSatori Review – What Benefits Athletes Can Expect from This Product?

What Is ISA-Test GF?

Choosing the right supplement to promote muscle growth can be confusing and overwhelming for most men. There are hundreds of choices in the market today, and each product comes with its own set of benefits of drawbacks. You should understand the needs of your body and learn more about factors influencing muscle development before investing in a product. Testosterone boosters have gained immense popularity in the recent years and are being used by both professional and amateur athletes to improve physique and boost energy levels.

For those who are new to the world of supplements, testosterone boosters act by elevating the levels of free testosterone in the blood. Testosterone is a natural steroid hormone that is produced by the male testes. The hormone is essentially responsible for the development of secondary characters in men. It boosts energy levels, enhances muscle development, and promotes fat metabolism. As a result, men with high levels of free testosterone in their blood develop a lean and muscular body and are able to maintain it as well.

Most men produce about 2.5 to 11 mg of testosterone per day but this amount is reduced significantly after the age of 30. Consequently, men notice a drop in their fitness levels and are unable to achieve the desired results with just diet and exercise. Millions of men are, therefore, dissatisfied with their body and suffer from poor self-confidence.

A good supplement can, nonetheless, have a huge impact and help men overcome physiological deficiencies that block serious muscle growth. ISA-Test GF is one such product, and it has helped thousands men boost their testosterone levels. Learn more about this supplement and its manufacturer. As always, it is prudent to go for a product that is effective and safe.



ISA-Test GF is a product of iSatori, a Golden, Colorado, based company that has been offering high quality supplements since 2001. The name iSatori has been derived from the Japanese word Satori, which means to “have an awakening.” It refers to a scenario where you can find answers to all your questions, and everything seems possible. iSatori’s founder, Stephen Adele, was frustrated with the prevalent misinformation in the fitness industry and decided to help consumers by providing them a “voice of reason.” He wanted to bring some “commonsense” back to the industry that was ruled by excessive hype and poor performance.

Stephen Adele worked with several medical professionals and nutritional biochemists to come up with a series of products that would help men build strong bodies and healthy minds. The company seeks to provide the “most loved, talked-about, well-respected, and sought-after nutritional products and solutions” for a healthy life. The company has been built with integrity and wants its consumers to be completely satisfied.

Every supplement offered at iSatori is made from finest ingredients, and each product has been subjected to independent clinical studies. In fact, as per the company’s website, the results of these clinical studies are the basis of all their claims. The company offers exceptional customer service and has collaborated with several top retailers across the nation to make the products more accessible to its consumers.


How ISA-Test GF Works?

ISA-Test GF contains natural ingredients that help increase the levels of free testosterone in the body while lowering the levels of female hormone estrogen in the blood. High levels of testosterone will promote improved muscle mass and stamina. Lower estrogen levels will prevent retention of water and accumulation of body fat. The ingredients of this supplement possess strong androgenic and anabolic properties that help achieve the desired hormonal balance. With regular use, you will notice an increase in muscle strength and muscle mass.

The company recommends men to take four capsules with one glass of water approximately one hour before exercise. If you are not working out on a particular day, take the capsules before bedtime. Most men will notice significant improvement after 8 weeks of use. However, you will see an immediate change within 30 minutes of taking the first capsule due to the Rapid Bio-Diffusion Delivery technology that uses a novel micro-particalization system to boost testosterone levels right away. You will not find this technology in any other testosterone booster at this time.

The benefits of this testosterone-enhancing and estrogen-reducing system have been proven clinically. Dr. Rob Mendel and Dr. Tim Ziegenfuss of the Ohio Research Group of Exercise Science and Sports Nutrition found a 154 percent increase in free testosterone levels and a 43 percent decrease in estrogen levels after three weeks of use. Additionally, all the health markers associated with liver, kidneys, blood pressure and cholesterol were normal.

All the ingredients of this supplement are completely natural. Hence, the consumers do not have to cycle the use of this product. It will not inhibit natural testosterone production mechanism in your body. You may, however, take a one or two week break after 12 weeks of use. You may take ISA-Test GF with other supplements to enhance the benefits.


Ingredients of ISA-Test GF

ISA-Test GF has been created by iSatori with utmost care and integrity. The main ingredient of this high quality testosterone booster is Fenugreek, or Trigonella foenum greacum, extract that contains potent anabolic compounds such as protodioscin, steroidal saponins, and other active compounds responsible for boosting testosterone levels. In fact, Fenugreek extract is the only natural compound containing the saponin Fenuside that acts like testosterone and binds to the corresponding receptors to promote muscle growth without inhibiting natural hormone production. Several independent clinical studies have vindicated these claims regarding Fenugreek.

Another important component of ISA-Test GF is Tribulus terrestris, a Bulgarian herb that improves testosterone production naturally. Many researchers believe that the Tribulus acts by increasing the levels of luteinizing hormone in the body, which in turn, boosts free testosterone levels. As per one clinical study, men who consumed 750mg of Tribulus extract per day noted a 72 percent increase in luteinizing hormone levels and 41 percent increase in free testosterone levels.

Additionally, iSatori has added Eurycoma longifolia, known as Longjax, to its supplement. The natural extracts of this plant showed 170 percent increase in testosterone levels in some animal studies. As per a study published in the 2007 edition of the Journal of International Society of Sports Nutrition, men taking Eurycoma extracts noted 32.3% lower cortisol levels and 16.4% higher testosterone. However, this extract is not a phytohormone and will not impact your body’s natural testosterone production.

The supplement contains a powerful anabolic growth factor stimulator called Somatrin that led to 140 percent increase in growth hormone levels when taken 30 minutes before exercise. It has zinc and magnesium, two important minerals that promote restful night’s sleep and lead to improved testosterone production as well. Other constituents include Ajuga turkestancia, a Central Asian herb used traditionally to enhance muscular strength and physical endurance. Rhaponticum that improves athletic performance and post-exercise recovery. Epimedium helps treat fatigue. P-450 Hesperedin and grapeseed extracts have strong anti-estrogen and antioxidant properties.



ISA-Test GF contains an unique combination of all-natural ingredients that boost testosterone levels, increase energy and endurance, and lower recovery times between exercises. Its efficacy has been proven clinically by. Dr. Rob Mendel and Dr. Tim Ziegenfuss of the Ohio Research Group of Exercise Science and Sports Nutrition. As per the study, most men found a 154 percent increase in free testosterone levels and a 43 percent decrease in estrogen levels after three weeks of use without any unwanted side effects.

I have used testosterone boosters in the past. They help a bit but most of them lead to so many side effects. I was just about to give up when I found this product. My gym instructor recommended it to me. I have been using it for almost three months and am seeing some serious benefits. My muscle mass has improved, and I feel more energetic even after the workout. I’m very impressed with this supplement. It really works.

I have noticed an improvement in my muscle strength as well. I may not look like a pro, but I am definitely happy with the results.

– Sed, Little Rock, AK, USA

Are you seriously looking to improve your physique? If yes, then avoid this product. Although iSatori makes a lot of promises, the product does not deliver. I tried it for more than six months. This was way more than the recommended 8 weeks. I did not notice any difference. I looked and felt the same. I was just downing 4 pills a day, which made me uncomfortable to say the least. This regimen was a complete waste my time, money and effort.

– Arthur, Birmingham, AL, USA

I have mixed feelings about this product. My friend loved it and has seen a lot of improvement. I did notice some muscle growth and improvement in stamina but it wasn’t as dramatic as his. Nonetheless, I’m happy with what it did. At least, I did not have any side effects. You should try it without expecting a lot.
