Isa-Test GF Review 1

The benefits of boosting testosterone levels are well known and widely accepted. As we get older, our bodies produce less and less of this male hormone, leaving us more prone to fat gain, less able to pack on muscle, more tired, weaker, and more lethargic. Find a way to get more T flowing through your body, and you’ve got an advantage over most guys your age.


Historically, the answer has been testosterone injections and testosterone replacement therapy, but these solutions often cause more problems than they’re worth. That’s why there are natural testosterone boosting supplements like Isa-Test GF from iSatori.  Isa-Test is one of many testosterone boosting supplements out there.  This one seems to hit the mark on price and results.  Let’s read more.


Benefits of Isa-Test GF


As a natural testosterone booster, Isa-Test GF can increase your testosterone levels and block the formation of new estrogen to keep you at the right balance for your life. That means:


  • Increased strength for better workouts.
  • More energy for workouts and life in general.
  • Easier fat loss.
  • Increased lean muscle mass.
  • Better endurance.
  • (And don’t forget boosted libido and improved sexual performance).


These are basically the same promises you get from every natural testosterone booster, so we took a look at the Isa-Test GF formula to see if there are any surprises there.


Isa-Test GF Ingredients


Isa-Test GF has a vitamin and mineral base that includes Vitamin C, Vitamin B6, Magnesium, and Zinc.


Then it moves on to the Isa-Test Proprietary Testosterone Boosting Blend which includes:


  • Isa-Test GF Review 2Tribulus Terrestris which is believed by some to work with your body to produce more natural tesosterone by secreting more Luteinizing Hormone which signals to the testes to increase the release of testosterone.
  • Epimedium which has been used in China to reduce fatigue and support sexual appetite.
  • P-450 Estrogen Inhibitor which is an antioxidant that can also reduce inflammation and allergic responses. It’s recently been hypothesized that it also can work as an anti-aromatase agent, which means it blocks the conversion of testosterone into estrogen.
  • Tongkat Ali (1)  which has been researched for its ability to improve sexual performance and increasing free testosterone levels.
  • Grapeseed Extract (2) which is an antioxidant that supports heart health as well.
  • Fenugreek Extract which is a very anabolic herb with protodioscin and steroidal saponins for boosting testosterone naturally.


And the Somatrin Proprietary Blend with:


  • Velvet Bean Extract which may increase Human Growth Hormone
  • Nettle Extract (3)  which supports the health of your prostate.


And the IsaFlow Proprietary Blend with:


  • Butchers Broom Extract which enhances muscle strength under adverse conditions.


How to Use Isa-Test GF


The recommended dose is 4 Isa-Test GF capsules taken with water about 60 minutes before working out. On non-training days, you should take your same full dose at bedtime. They also provide a “more advanced” dosing strategy with their Testosterone Solution Diet and Training Plan.”


There’s no need for loading, and you don’t have to cycle on and off because Isa-Test GF doesn’t shut down your natural testosterone making process. But they do recommend a week or two off after about 12 weeks, just to start again fresh. That’s usually a good idea with most supplements.


Isa-Test GF Before and After Reviews


Isa-Test GF is sold through several different online retailers, which makes it very easy to find customer feedback. The majority of what we found is positive, though not particularly glowing. We found a lot of reviews that look like this:


“Ive been taking this supplement for approx 4weeks. Ive noticed a slight difference in aggression, and im sure theres a rise in libido”


Probably the most commonly mentioned positive comment is that it improves sleep.


“I took at 4 caps for about 2 weeks, and noticed an increase in sleep quality and when taking it at 5 caps sleep was even a little bit better, but when increased to 6 I was knocked out can sleep through anything woke up feeling refreshed”


But there is some negative feedback as well. A few guys got headaches, and several more just didn’t see any effects at all:

“I had the worst unending headache the entire time I took this product. The product may work for you, but quit taking it and get your money back if you start to have headaches.”

“I was using this for a while but I never noticed a difference. The only reason I used it as long as I did was to see if I would eventually notice a difference. I didn’t.”


Who is iSatori?

Isa-Test GF Review 3


Satori is a Japanese word meaning “epiphany or an awakening.” Founder Stephen Adele added the “i” for the personalized effect. He wanted to create a supplement company based on integrity and the desire to help improve workouts and results for using naturally and healthy ingredients. He founded iSatori in 2001 to be a provider of total solutions to the health conscious athlete.


Where to Buy Isa-Test GF


Isa-Test GF is available through several different online retailers including Amazon and Bodybuilding.com. You can also pick some up at the iSatori website. A 104-count bottle will last 26 days, and it costs $41.99 at the official website. On Amazon, it’s $35.99, and at Bodybuilding.com, that same bottle costs $36.70. So if you’re in the market, you’ll want to shop around.


Our Isa-Test GF Conclusion


We’ve got mixed feelings about Isa-Test GF. The reviews are mostly pretty positive, but they lack the fire and excitement you want to see when fitness buffs are raving about their latest find. That and the headaches are reason to wonder if you’d be getting your money’s worth with Isa-Test GF.
