FAQs - ISA-TEST® GF
Fenugreek Extract (Trigonella foenum greacum) is gaining support from the scientific and weight training communities alike. It contains a variety of powerful anabolic compounds, among them protodioscin and steroidal saponins. Unlike other natural testosterone-boosting herbs, fenugreek extract contains a host of active compounds in addition to protodioscin and saponins—all responsible for significantly boosting testosterone (or T, for short) levels, muscle mass, and libido.∆ Research suggests the majority of these saponins exist as saponin glycosides. Fenuside is a set of potent saponin glycosides that have been specially extracted and standardized to yield the highest potency and purity for maximal benefit. Since fenugreek extract is the only natural substance that produces these unique Fenusides, what's interesting is fenugreek extract "acts" more like testosterone by binding to the testosterone receptor sites and creating more testosterone. And as a result, it amplifies the androgenic and anabolic activity in the body. Equally important, though, it does this without shutting off the body's own natural production of T. In a recent randomized, placebo-controlled clinical trial with 60 men, fenugreek extract nearly doubled (+98%) users' testosterone.
It's for these reasons, fenugreek extract is one of bodybuilding's best-kept secrets because, as confirmed by multiple research studies, it demonstrates strong androgenic and anabolic properties to boost libido and increase muscle mass.∆
Tribulus terrestris (otherwise known as Tribulus or by the active compounds, saponins and protodioscin). This herbal extract was originally discovered and researched in Bulgaria (the home of many of today's Olympic lifters). Even though it's been lopped into the same boat as prohormones, it's absolutely, positively not a hormone. In fact, tribulus works with your body—not to inhibit it—but to help support its natural ability to produce T and restore it to within "normal" ranges. Many theorize this is possible because tribulus works by increasing luteinizing hormone (LH), which in turn tells your body to start producing more T. In fact, one study done with healthy males who supplemented with 750 mg of tribulus per day showed a 72% LH increase and an impressive 41% increase in free T levels. Another study showed participants had increased libido, sexual behavior, and sperm production. As a result of these findings, tribulus has become extremely popular and widely accepted as a safe and effective alternative to prohormones.∆ⱡ
Eurycoma longifolia—better known by its patented form, Longjax™—animal studies have shown significant effects of Eurycoma longifolia on sexual behavior and increases in T—one showing an up to 170% increase in T. Another plus is, because Eurycoma isn't a prohormone, it won't suppress your natural production of T: instead it boosts it. In a study reported in the 2007 ISSN Journal, 30 men participating in a 24-hour mountain biking race were divided into two groups. One group (15) received Eurycoma, and the other group (15) received a placebo. The researchers measured both cortisol and testosterone and discovered that the men who used Eurycoma enjoyed 32.3% lower cortisol levels and 16.4% higher testosterone. They concluded, "These results suggest that Eurycoma longifolia extract may help to maintain normal levels of cortisol (low) and testosterone (high) and thus promote an overall 'anabolic' hormonal state during intense endurance exercise." Users on the street have also experienced favorable results. It's been noted that 80% of people who use Eurycoma notice an immediate, definite increase in their libido. According to the science, it appears Eurycoma is a potent stimulator of T levels and sexual arousal and vigor, which is a positive benefit! Currently, there have been no negative side effects reported from the use of Eurycoma.∆ⱡ
Zinc/Magnesium—zinc aspartate and magnesium aspartate—supported by two studies, this combination of minerals has shown its worth in the lab and in the real world. It's become apparent for some time now that consistent resistance training causes a depletion of vital minerals in the muscle cells. One such critical mineral is zinc. Zinc has also been shown to play an important role in the body's ability to get a restful night's sleep. When you are able to get a sound night's sleep, your body releases many more hormones, namely T and growth hormone—two very powerful anabolic hormones for building muscle mass. In fact, a larger percentage of T secreted daily in men occurs during sleep, and levels peak during the early morning. As you can see, a good night's sleep is vitally important for increasing T levels; thus, supplementing with zinc can help replace not only the "depleted" zinc from weight training but supply the body with adequate amounts for a restful night's sleep... so your T levels can continually be improved. What's more, zinc and magnesium supplementation have both been reported to significantly reduce levels of the catabolic (muscle-wasting) "stress" hormone, cortisol, by 59% and 25% respectively. Because zinc and magnesium deficiencies are both commonly found in the general public and are even more prevalent in intensely trained athletes and weight trainers, this combination has become popular.∆ⱡ
We suppose it's also safe to say that because zinc and magnesium is merely a harmless mineral combination and not a prohormone, it's becoming more and more widely used by competitive athletes, including college, professional, and Olympian. And with great success!∆ⱡ Ajuga turkestancia is a traditional herbal remedy used in Central Asia for thousands of years to enhance muscular strength and physical endurance under harsh, exhausting conditions.∆ⱡ
Rhaponticum is a plant that grows throughout eastern Siberia, which Soviet scientists used as a replacement for anabolic steroids. Currently, rhaponticum is listed in the Russian Pharmacopoeia as a remedy for increasing work efficiency under stressful conditions, improving athletic performance, and promoting recovery after intense muscular workloads.∆ⱡ
Epimedium, also known as "horny goat weed," is grown as an ornamental herb in Asia and the Mediterranean region. It has been used for centuries to treat fatigue and boost sex drive. Recent studies in humans have shown epimedium also decreases cortisol and enhances immune function.∆ⱡ
P-450™ Hesperedin ([(S)-2,3-dihydro-5,7-dihydroxy-2-(3-hydroxy-4-methoxyphenyl)-4-H-1-benzopy-ran-4-one]) is an interesting citrus bio-flavonoid found primarily in oranges and lemons. The antioxidant properties of hesperedin are fairly well established, and more recent studies have indicated hesperedin may also have anti-inflammatory, anti-allergic, hypolipidemic (reduces total cholesterol, including HDL), vasoprotective, and a host of other actions. But a newly discovered, added benefit of this substance may be even more profound for weight trainers since hesperedin appears to be a potent anti-aromatase. Aromatase is the enzyme involved in the process through which hormones in the body are converted to estrogen. As an anti-aromatase, hesperedin reduces the formation of estrogen in the body. This is important because the conversion of testosterone to estrogen is thought to increase as we age (at least in males), and because increases in estrogen are linked to a whole host of unwanted side effects, like increased bodyfat, testicular shutdown, water retention, and in extreme cases, even gynecomastia (a "female-breast-like" appearance) or testicular cancer.∆ⱡ
What's interesting is that no one has used this powerful anti-estrogen compound—until recently that is. Probably because hesperedin was virtually unknown until recent research indicated its potential positive effects for inhibiting estrogen and because it takes an immense amount of resources to learn how to extract such a compound from its natural source. Recently, however, hesperedin has been trademarked under the name P-450. Since it's a natural compound and it doesn't "shut down" your body's natural production of T, you can use it for extended periods of time.∆ⱡ
Grapeseed extract is an extract from red grapes containing the active compounds known as oligomeric proanthocyanidins (OPC). OPC appear to have potent antioxidant and cardio-protective properties. Recent studies have also shown that OPC have anti-estrogenic properties.∆ⱡ
