ISA-TEST GF is a precise combination of natural ingredients clinically shown to support an increase in natural testosterone within normal range and a reduction in the "female-hormone" estrogen.* It's designed to help promote noticeable gains in strength, muscle mass, as well as improved sexual drive and performance.* Adding ISA-TEST GF into your intense training program is a surefire way to help increase testosterone and support performance in and out of the gym. With a clinically studied formula and strict manufacturing guidelines, you can be confident that ISA-TEST GF delivers on its promise of both potency and purity. ISA-TEST GF is truly the platinum standard in testosterone and anti-estrogen augmentation.* HOW DOES THE RAPID BIO-DIFFUSION DELIVERY SYSTEM WORK? As a dietary supplement, take 4 capsules with a full glass of water one hour prior to exercise. On non-training days, take 4 capsules one hour prior to bedtime. Take with or without food. FOR BEST RESULTS, use continuously for a minimum of 8 weeks. HOW DOES THE RAPID BIO-DIFFUSION DELIVERY SYSTEM WORK? With the guidance of a leading pharmaceutical specialist and medical doctor, iSatori developed an exclusive Rapid Bio-Diffusion Delivery™ technology, which uses a sophisticated "micro-particlization" process, so it starts working from the very first dose to help the body's natural testosterone production.* Within 30 minutes of taking this supplement, you'll begin to "feel" it going to work… an instant rush of testosterone… because of its fast absorption and increased potency.* No other testosterone formula contains this state-of-the-art delivery technology. You can find it only in ISA-TEST products. WHAT DOES THE RESEARCH SAY ABOUT ISA-TEST GF, AND IS IT SAFE? The efficacy of its incredible testosterone-enhancing and estrogen-reducing effects were scientifically documented by researchers Rob Mendel, PhD, and Dr. Tim Ziegenfuss of the Ohio Research Group of Exercise Science and Sports Nutrition! The conclusion of the study, after just three weeks (and it works on a progressive basis), Free or usable testosterone levels increased and estrogen levels decreased. Equally important, all of the subjects' health markers (e.g., liver, kidney, cholesterol, blood pressure, etc.) were normal and healthy. So, we know, without a reason of a doubt, it works fast and is safe.* DO I NEED TO "LOAD" OR "CYCLE"? "Loading" or "cycling" is not necessary. And because it is an herbal-based supplement and it won't shut down your body's own production of testosterone, you don't need to cycle it and can use it for extended periods of time.* It is, however, always a good idea to take a break for one to two weeks, after using any kind of supplement after 12 weeks.
