What Is ISA-TEST GF?

ISA-TEST GF is a precise combination of natural ingredients clinically shown to cause increases in testosterone and a reduction in the “female-hormone” estrogen.ⱡ It’s designed to promote noticeable gains in strength, increased muscle mass, and improved sexual drive and performance.∆

What does BIO-GRO do?

Muscle

Promotes healthy body composition, while supporting healthy testosterone levels without banned substances, illegal ingredients, or nasty side effects.∆

Strength

Increases work efficiency under stressful conditions, improving athletic performance, strength, and promoting recovery after intense muscular workloads.∆ⱡ

Performance

Confirmed in research studies, it demonstrates strong androgenic and anabolic properties to boost libido and increase muscle mass. Class-leading ingredients in ISA-TEST GF have been included to help increase performance and libido. Epimedium, also known as “horny goat weed” has a long standing tradition of helping decrease feelings of fatigue and improving sex drive. ∆

Frequently Asked Questions

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.∆ⱡ 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.∆ⱡ 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 by up to 154%, and estrogen levels decreased by up to 43%. 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.∆

How can I take this product for maximum results?

Take a full dose (four capsules) 60 minutes before weight training. On non-training days, take one full dose before bedtime to optimize the restorative effects of testosterone while sleeping.

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.

Why is it so important for men to suppress estrogen?

While estrogen does have important functional roles in men (such as maintaining bone and cardiovascular health), in excess, estrogen can promote water retention, increase bodyfat, and cause gynecomastia; that is, the female-like increase in breast tissue. This is particularly true in men who are already overweight and/or have elevated blood sugar levels. Some research even indicates increasing levels of environmentally produced, synthetic estrogens (called xenoestrogens) have the potential to disrupt the delicate endocrine system in men, potentially reducing sperm counts and increasing the risk of testicular cancer. The goal with this product is to keep estrogen at levels that optimize health and body composition.∆ⱡ

Are there other supplements I should take to enhance the benefits?

Although ISA-TEST GF has been designed as a standalone supplement, there are three other supplements you can take to magnify its health benefits. First and foremost is BIO-GRO™, which compliments elevated te4stosterone with key bio-active peptides including growth factors. Second is protein such as 100% BIO-ACTIVE WHEY before and after training. And third is a high-quality creatine like CREATINE A5X™ ideally taken within minutes after each training session.

This has literally been my go-to test product for the last couple of years. I normally pick it up at Vitamin shoppe, but sometimes when there is a special, I buy it here. Of course you get a jump in sex drive and “focus”, but what I seem to get beyond that is a good muscle hardness and fullness. When i cycle off for a couple weeks, I can tell the difference. I’ve made consistent gains over the last few years as a Natty physiques competitor and I would say this has helped quite a bit. I do recommend this to my friends.

I’ve used this for probably a couple years now and it has done exactly what it says. I typically take it before sleeping and I feel I get a better sleep. It think a change in my energy is related to this and the increase in test. When I do go off this for a couple weeks, the second week I feel more sluggish. Workouts are great on this – just strong and confident is how I would describe them. Not like taking a pre-workout. I use ISA-Test and I feel like I’m on my game. I’d recommend it for sure.
