What to look for in a Great Natural Testosterone Booster

Posted by Mark Hamilton on

Here are some of the key ingredients I look for in a natural testosterone Booster.


In a 12 week study on 109 men between 30 and 55 years of age, supplementation was shown to increase sex drive, erectile strength and semen volume.

The men in the study also showed significant fat loss!

Fat locks up hormones like testosterone so the added ability to help aid in fat loss is yet another positive for longjack.



The amazing Rhodiola Rosea is a herb native to Siberia and possess some outstanding adaptogenic properties, from stress, mood, improved sleep, energy and ATP production and cortisol suppression.

This incredible Russian herb on top of the amazing adaptogenic health benefits also helps us to keep our endocrine system functioning properly. This is our ability to produce key hormones such as testosterone.

Rhodiola stops testosterone being shut down when the body is put through physical stress (a workout) and also reduces estrogen.


For centuries, Siberian villagers brewed Rhodiola tea for everything from anemia to libido. The Vikings drank horn cups full of it before a raid. Rhodiola certainly has the potential to bring back that alpha male in you.


Tribulus terrestris

 This incredibly powerful herb has been used for many years in sports nutrition with incredible results. The key is the active ingredient which is Sannopins, and this is why we use a 90% Sanopin content in our formula. This nearly pure tribulus is a key component to our testosterone boosting and estrogen reducing formula.

 Tribulus Terrestris also has a huge impact on strength and energy levels and in one study sex drive increased by a massive 70%.

 Now if you Google Tribulus Terrestris you will find quite a lot of negatives in terms of comments, research and opinions. However there are many poor tribulus products on the market as usual, pedling the anabolic benefits of a completely different tribulus.

What makes Tribulus an all-star muscle-building supplement would be the presence of saponins—steroidal saponin protodioscin to be exact. In a study, researchers in Lithuania gave athletes 625 mg of a 40% saponin that contained Tribulus extract 3 times a day for a period of 20 days and found that circulating testosterone had significantly increased during the first 10 days of the experiment.

The researchers from that study believe Tribulus works by raising the levels of luteinizing hormone (LH) or follicle-stimulating hormone (FSH). Both are gonadotropins and thus stimulate the gonads in both males and females. This prompts the creation of testosterone in men and estrogen in women. The other factor would be how Tribulus plays with blood glucose, lowering the level and creating a response in the body that raises testosterone.

Other research suggests that Tribulus is adaptogenic. In other words, the herb will only work when it can help bring the body back into homeostasis, or “equilibrium.” With this in mind, you are going to want to cycle your dosage of the herb.

The Tribulus we use has a massive 90% saponin content so absolutely huge potency and quality.

Tongkat Ali Affects Testosterone Levels

In a 2012 study, 76 men were brought into a lab and given 200mg of a standardized water-soluble extract of tongkat ali for one month. At the start of the experiment, only 35.5% of the subjects had testosterone levels in the normal range. At the one-month mark, 90.8% of the subjects’ testosterone levels had elevated into the normal range.


In another study, researchers observed the effects of tongkat ali supplementation on 25 physically active men and women between the ages of 57-72. Each of the 13 men and 12 women were given a daily dose of 400mg of tongkat ali extract. Five weeks later, the men experienced a 15.1% increase in total testosterone levels and a whopping 61.1% increase in free testosterone levels. The female subjects experienced even more drastic results: an average increase of 48% in total testosterone levels and a 122% increase in free testosterone levels.


Tongkat Ali Affects Cortisol Levels

Cortisol is the hormone your body releases in times of stress. It is catabolic in the sense that the more of it you have in your body, the more likely your body is to break down muscle for energy. Also, it is a steroid hormone and is derived from the same raw material as testosterone (i.e. higher cortisol equals lower testosterone). 

Published in British Journal of Sports Medicine, 30 men between the ages of 31 – 52 were recruited to supplement with Tonkcat Ali.

This study showed a 66% reduction in Sex Hormone Binding Globulin (SHBG) and an increase in free testosterone in 73% of the men. (3)

SHBG binds to testosterone and locks it up meaning its not free to build muscle, increase strength or libido.

When you reduce your SHBG levels you typically see an increase in free testosterone levels just as this study showed.


 Fenugreek extract is a rich source of vital minerals and nutrients, but the secret sauce is the steroidal saponins. These powerful chemicals support the production of testosterone, the hormone that’s gonna get you lifting heavier and faster.


Fenugreek seeds are rich in steroidal compounds like glycosides and saponins including diosgenin, yamogenin, gitogenin, tigogenin, and neotigogens.


 Extract from Fenugreek seeds contains high concentrations of steroidal saponins, chemical compounds known for regulating blood sugar levels and supposedly boosting your LH (sex hormone) and testosterone (the MANLY man hormone).


Liquorice Root

Liquorice is a very potent plant steroid that is fantastic for suppressing cortisol and elevating testosterone in the right amounts. Take too high a dose and it will have completely the opposite effect so milligramage is everything.

OESTROGEN Licorice is believed to exert an alterative action on oestrogen
metabolism, this would imply that it has an adaptogenic action peaking out the highs and lows of oestrogen.
Glycyrrhetinic acid antagonises many of the effects of oestrogens, particularly those from external sources (xeno-oestrogens).

- Licorice exerts steroidal effects of its own and demonstrates important clinical significance for the use in aiding withdrawal of steroidal anti-inflammatory drugs. The hormonal supportive effects offered by licorice may be useful in cases of chronic fatigue syndrome (CFS) and adrenal exhaustion states. This will also reduce cortisol which will increase testosterone.

– Glycyrrhizin and glycyrrhetinic acid induce interferon - the body’s natural anti-viral compound. Glycyrrhizin inhibits the growth of several DNA and RNA viruses, namely, vacinia, herpes simplex, vesicular and stomatis viruses.

LIVER SUPPORTIVE – Glycyrrhetinic acid may inhibit chemical induced liver damage. It acts by preventing free radical damage as well as inhibiting the formation of free radicals.

Vitamin D3

A new analysis has found that low levels of vitamin D are independently associated with low levels of testosterone in healthy middle-aged men.


Key for testosterone production and one of natures strongest pro hormones, without side effects. Vitamin D has a correlation with testosterone levels, more being deficiency in vitamin D will reduce testosterone quite dramatically. So we put vitamin D3 in this formula to not only maintain healthy levels but increase testosterone production if deficient.


At the end of one particular study, vitamin D concentrations increased by an average of 53.5 nmol/L in the vitamin D group, but held steady in the placebo group. The vitamin D group also experienced a significant increase in total testosterone levels (from 10.7±3.9 nmol/L to 13.4±4.7 nmol/L; p<.001), bioactive testosterone (from 5.21±1.87 nmol/L to 6.25±2.01 nmol/L; p=.001), and free testosterone levels (from 0.222±0.080 nmol/L to 0.267±0.087 nmol/L; p=.001). The placebo group, on the other hand, saw no significant change in testosterone levels.


D Aspartic Acid

 D-aspartic acid can increase the release of a hormone in the brain that will ultimately result in testosterone production

Clinical studies show DAA can increase natural test by up to 48% in healthy young men.

Significantly increased levels of testosterone

Increase endurance during exercise

Improves mood and concentration

Increases levels of growth hormone in the body

Help support testosterone and promote overall well-being


DAA holistically encompasses the induction of the internal testosterone synthesis in the male body, assuming a minimum biosynthesis and/or the reduction of the negative impact of hormones, such as, among others, oestrogen and prolactin, on athletes, thereby setting new trends in the production of effective and physiologically optimised testosterone boosters in terms of the effectiveness of sports exercise.   



At present, it seems likely that ashwagandha could help increase testosterone levels in stressed individuals, possibly by reducing the stress hormone cortisol.

Ashwagandha KSM-66 supports the functioning of the nervous system (it improves the memory), 

Ashwagandha KSM-66the functioning of the reproductive system (it boosts sexual functions), 

Ashwagandha KSM-66the functioning of the immunological system (it improves cell immunity),

Ashwagandha KSM-66 has antioxidating properties, which help protect cells against reactive forms of oxygen


Zinc Picolinate

 Zinc is a key mineral that cells use to metabolize nutrients. Immune function, DNA and protein production, and cell division are all related to zinc levels in the body. Zinc also enables the male body to produce testosterone. Because of this, your levels of zinc may affect erectile dysfunction


There is pretty strong evidence for the fact that zinc also affects testosterone production. This study found that zinc supplementation could produce a very large increase in the testosterone levels of various men. If you look at the numbers, you can see that the increase is pretty significant.


Bulbine Natalensis

Bulbine Natalensis is a herb from South Eastern Africa that has been traditionally used as an aphrodisiac and testosterone booster.

Bulbine Natalensis encourages increases in muscular development & strength, and improves sex drive & mood. It specifically increases the signalling of Gonadotropin-Releasing Hormone (GnRH) to stimulate the release of Luteinizing Hormone (LH) which directly increases the natural production of testosterone.

In addition, Bulbine Natalensis elevates testicular cholesterol, which is required to synthesize new testosterone.
