Directions For ISA-TEST GF: As a dietary supplement, take 4 capsules with a full glass of water one hour prior to training. 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.∆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.

Excellent Service and Product

This product was bought as a gift and shipped directly to my home. I can't review how well the product worked because I couldn't even get a full month out of the bottle as half of the capsules were broken open in the bottle.UPDATED: Excellent costumer service and after receiving a new bottle I can say it is an excellent product!

Good Product

You have to workout as hard as you otherwise would and you will see the strength gains. This isn’t a miracle drug, but you will get stronger as long as you put the work in.
