iSatori ISA TEST GF Testosterone Booster Review

iSatori ISA TEST GF Testosterone Booster Review First Look:

Due to a bout of Gastroenteritis it seems I will not be raining now until I have fully recovered which may be next week.

My vacation away to Europe for a friends wedding was great…initially.

We hit the Champagne region and a town called Epernay which produced Moet. Naturally we went on a tour of their cellar and sampled the delights. Then we sampled lots more local delights which unfortunately was followed by a 10 hour drive to Lake Como in Italy. I didn’t bump in to George Cloony though.

After a great 3 day long wedding party in the Tuscan Hills we headed West to the coast whereby my healthy breakfast consisting of smoked salmon literally ruined me. This is the 8th day of not feeling amazing shall we say. And probably the 15th day of not hitting any weights.

To make matters worse, I have to move house in 5 days. I am downsizing too. Closer to the city with no parking and no garage for my gym equipment.

It seems the gym is on hold for the moment. This irritates me.

I also feel weak because of the illness and had only just started eating again after a long spell of sleepless nights and no food. Just a few slices of white bread has sustained me.

I am concerned that with out the proper food and without proper weight lifting my test levels could take a hit.

It could also effect you in a time of illness.

So, let’s take a look at this testosterone booster from iSatroi, it also hints at being a growth hormone too..

We have already tested a testosterone booster from iSatori before under the C.T Fletcher series. It scored an ‘okay’ result.

This looks much like its fat burner sister product which, just like this, is wrapped in a metallic red film which looks great.

It has a high quality finish and stands out on the shelf.

Let’s discover how good this is.


Vitamin C – Its antioxidant properties mean vitamin C provides neuroprotective effects and benefits for blood flow. By protecting the testes from oxidative stress, vitamin C can also preserve testosterone levels.

Zinc – An aphrodisiac and Testosterone Booster.

Zinc is also very important for the functioning of the enzyme, hormone, and immune systems.

Studies demonstrate that in very high doses, zinc can act as an aromatase inhibitor and reduce estrogen levels.

It is also a potent antioxidant and can provide benefits for prostate issues.

Vitamin B6 – Vitamin B6 helps testosterone levels by stimulating androgen (a steroid hormone that acts as a precursor for testosterone) receptors in your body, making your testes produce testosterone.

Magnesium – Research into magnesium supplementation also increased testosterone production in men.

Fenugreek – Fenugreek is a proven ingredient as found in our benchmark testosterone boosting product; Testofuel.

Research shows that a fenugreek seed extract can reduce daily fat intake in overweight men when taken by mouth at a dose of 392 mg three times daily for 2-6 weeks.

Tribulus – My only beef is that although Tribulus is touted as a wonder plant extract that helps strength gains and it was the secret drug of choice by Easten Bloc Olympic lifters in the Cold War (I think that was anabolic steroids actually judging by the women’s beards and square jawlines!)

The issue is that it has not been scientifically proven to raise testosterone levels in any shape or form.

In fact, in studies using elite professional Australian rugby players as participants Tribulus did not produce the large gains in strength or lean muscle mass that many manufacturers claim can be experienced.

Avoid like a medieval plague if you are looking for muscular gainz.

Horny Goat Weed – Epimedium, the suspected active component of horny goat weed, appears to act as a phosphodiesterase inhibitor, similar to some drugs used for erectile dysfunction.

It does not, however, stimulate testosterone production.

Hesperidin – In animal testing at relative doses as what humans would take this seems to offer cardioprotection and protective of the organs, in particular the brain.

May also improve blood flow. Very little else has been found out.

Longjack Extract – Eurycoma (Tongkat Ali, LongJack) is a pro-fertility agent and aphrodisiac that appears to have a large body of evidence supporting this role and some evidence suggesting it may be an anti-estrogen and pro-erectile agent.

However, there is a lack of evidence for testosterone boosting in humans, although some very limited evidence in animals.

Ajuga Turkestanica – This plant extract is loaded with steroids which sounds exciting and ‘steoidy’ – probably just made that word up!

It sounds better than it reacts anyway, because, ecdysteroids have not been found to interact with estrogen or androgen receptors nor influence levels of these hormones in the body.

Grape – Grapes, or the chemicals within them, especially oligomeric proanthocyanidin complexes (OPCs), have been touted as powerful antioxidants yet in humans there is a real lack of clear evidence that there are any real benefits.

Rhaponticum carthamoides (Russian Leuzea or Maral Root) – This is an herb used in traditional Siberian and Russian medicine to bolster physical performance particularly after illness, in addition to being used as a general physical enhancement and male sexual enhancement aid.

It is a source of molecules known as Ecdysteroids which are hormones involved in the molting and maturation process in insects but have different actions when ingested by non-insect organisms.

Despite being an ‘insect steroid’ of sorts, ecdysteroids have not been found to interact with estrogen or androgen receptors nor influence levels of these hormones in the body.

Velvet Bean (Macuna Pruriens) – This is actually good for treating people with Parkinsons. There’s a mixed bag of results for testosterone but look mainly positive.

Results have shown an increase in testosterone levels in infertile men, however, results are very limited for fertile men.

It is effective to reduce cortisol levels – high stress levels can harm testosterone production.

Nettle – Good for reducing inflammation and an enlarged prostate but has no effect on testosterone.

Melatonin which is usually produced in response to low light levels, causing one to feel sleepy. More sleep means more muscle growth and development.

Ruscus Aculeatus – Limited evidence suggests this helps blood flow by constricting veins. Sounds counter intuitive.

However, it seems to prevent blood from pooling in organs and keeps the blood flowing constantly, probably at a higher pressure.

Hesperidin Methyl Chalcone – Like Hesperidin but much more soluble. Seems to protect organs such as the brain and heart.


4 capsules per day which is an optimal amount. However, we are instructed to take these all at once.

We would recommend that you have 4 tablets spread evenly across the day, as per the best testosterone booster on the market.

This way your body has a constant trickle of the ingredients to work with in order to stimulate testosterone.

The daily dose is an adequate 2491mg, but it isn’t pushing any boundaries.

Effects & Benefits:

There’s only 8 effective ingredients present.

Fenugreek is found in the best testosterone boosters due to its effectiveness and B6, Zinc and not forgetting Magnesium are the cornerstone of any good testosterone booster too.

Zinc, Magnesium and B6 are what a ZMA supplement consists of.

We also have Macuna Pruriens which is a regulator of stress, high stress levels reduce testosterone levels. It can also raise testosterone levels in men who are infertile. This is found in Prime Male which we consider to be one of the best testosterone boosters on the market.

Vitamin C can help protect the testes and therefore testosterone levels from oxidative stress.

Melatonin while not having direct effect on testosterone levels can help you sleep more, the more you sleep the more you release growth hormone when you recover.

Nettle can help lower inflammation and too much inflammation can hinder testosterone production.


With such a wealth of ingredients present it is a shame to see so many ingredients that are proven to directly help stimulate more testosterone production such as D3, K2 and D-Aspartic Acid.

It has to be noted that this consists mainly of a proprietary blend. This is not good and is a huge scam that is seen so often in the supplement biz. Anything with a blend that is not transparent should be avoided.

It is also a shame to see Tribulus too. This is another scam of sorts. It has been circulated so much as a testosterone booster that no one questions it. Yet, it has yet to have any proven abilities. It’s like telling yourself a lie so many times that you believe it. I also believe I am 5’10″…

However, the real issue here is the lack of directly testosterone boosting ingredients (plenty are available) and too many other, unproven ingredients. Not to mention the blend issues.

iSatori ISA TEST GF Testosterone Booster Review Conclusion:

This offers some good, stable and proven ingredients.

Zinc, Magnesum, B6 and Vitamin C are good. We know the levels included and this is good too.

We then have a further 4 ingredients that while not necessarily direct testosterone simulators do assist with the overall production and testosterone levels.

However, these are lost with a proprietary blend and as such we have no idea whatsoever of the exact content.

We could have useful amounts for our body to work with, or, as commonly seems to be the case, we may merely only have trace amounts available that will have no benefit at all.

These 8 ingredients which are beneficial are plucked from a total of 17. This means less than 505 of the product has any potential to be beneficial.

A terrible hit rate there and really gives me no options but to avoid this testosterone booster.
