A Gentlemen’s Guide to Natural Testosterone Boosters

Best Natural Testosterone Booster

Best Natural Testosterone Booster

So you want to build more muscle? Join the club.

Just one problem… Or three: Diet, Training and Testosterone.

These are the building blocks of mass, and only 2 of those are in your control: diet and training. Without testosterone on your side to make the ‘holy trinity’ you can only get so far.

Natural Testosterone Boosters are your best shot at changing it, unless you want to be stuck at the same weight all your life.

Full of proven benefits a Natural T-Booster can:

  • Boost Testosterone Levels – Uses clinically proven natural ingredients
  • Increase Muscle Strength and Size – Progress faster in the gym
  • Lift Mood and Enhance Focus – More confidence and energy during workouts
  • Increased protein synthesis – Absorb more of the protein you are eating

Picture it this way: Women can only build a small amount of muscle naturally, no matter how hard they train and diet. They hit a physical peak – and are unable to progress any further – This is due to their naturally low testosterone levels.

Men hit a similar peak for the same reasons, it just takes longer – the only difference between the two is testosterone. It’s all about your genetic limit – some guys have more T, others have less. Testosterone boosters are products formulated to expand that limit. They get the most out of your training and bring the gains you work your ass off for.

Why Testosterone Boosters?

Testosterone Boosters are an all natural way to raise testosterone. Unlike steroids, they have no side effects and don’t drain your T-levels after you stop taking them – because who wants shriveled balls? Or even worse – ‘bitch tits’.

Proven Ingredients

Green Tick1T-Boosters are comprised of safe, clinically proven natural nutrients that the body requires to produce testosterone.

Many of these components don’t occur enough in our diets, but are required to boost testosterone – these supplements fill in the gaps. The top ingredients are backed by respected studies with solid proof of their effectiveness.

Better on a Bulk

When putting on mass you consciously make an effort to consume more protein – especially on a bulk.  You’re just making sure the muscles are getting the good stuff as much as possible and you’ll deal with the surplus later.

bulk-beef-cutsBut bro – This could be hindering your progress. Protein is important for lean muscle mass, but too much can lower testosterone… significantly. Raised stress hormones and other factors from having to process all that extra protein can seriously negate your testosterone levels.

Various studies have looked into this claim and seen a high-protein diet has less free testosterone levels than a low-protein one.

Testosterone Boosters will help restore the losses by keeping T levels elevated and help you get the most out your bulk by acquiring more effective results.

What are the best proven ingredients?

A testosterone booster is only as good as the ingredients it’s made of. After some long nights of solid research, we’ve pinpointed the most effective nutrients for boosting testosterone – and whether they produce testosterone, free up testosterone or suppress estrogen.

L-Aspartic-acid-zwitterion-3D-ballsDAA (D-Aspartic Acid) – Testosterone Production: This is by far the most potent ingredient for boosting testosterone. Used as a testosterone booster by sportsman for an added edge, and also aids infertile men. DAA reacts with the brain causing a release of hormones such as the luteinizing hormone (required for testosterone), follicle stimulating hormone and growth hormone. It also loosens the rate-limit of Testosterone Synthesis, increasing T-Levels.

Study: http://www.ncbi.nlm.nih.gov/pubmed/19860889

d3Vitamin D3 – Testosterone Production: Specifically D3, the other strains of Vitamin D are nowhere near as effective. Technically a hormone, we absorb D3 from the sun and is heavily linked to testosterone production. The link is believed to involve the luteinizing hormone, and the evidence to support D3’s effects on testosterone is staggering.

Study: http://www.ncbi.nlm.nih.gov/pubmed/20050857

Magnesium-505x336Magnesium – Increases Free Testosterone: Magnesium works in a different way. Around 60% of the testosterone in men is bound to Sex Hormone Binding Globulin (SHBG) this takes away the testosterone’s anabolic potency and removes it’s availability from the rest of the body. Magnesium lowers the SHBG count significantly, allowing the body’s free testosterone to increase in number.

boron_crystalline_1200Boron – Increases Free Testosterone/Estrogen Suppressant: Boron affects hormones and other processes in the body, including mental cognition. It has been seen to raise free testosterone and decrease estrogen by reducing SHBG, and is a great addition to any test booster.

zinccyZinc – Testosterone Production/Increases Free Testosterone: A key builder of T levels, especially if you work out a lot. Zinc (first study linked below) prevented a drop in testosterone levels in excessively training wrestlers. The placebo group had their Testosterone levels inhibited, succumbing to the exhaustion from the workload, and noticeably dropped. It has also been seen to lower SHBG and increase free testosterone.

Outdated Ingredients

red-wrong-cross-hiEarly T-Boosters were undeveloped and relied upon hearsay rather than hard evidence and studies. A range of ineffective ingredients were constantly included; some of which are still being used today.

Tribulus Terrestris & Deer Antler Velvet are the top two offenders on this list and have been repeatedly shown to have no effect on T levels.

SpotMeBro’s Top 3 Testosterone Boosters

Keeping the above advantage and ingredients in mind, these are the current top testosterone boosters on the market. Other factors that were also considered were dosage and product guarantees.

1. TestoFuel

Studying the ingredients, dosage and company rep – TestoFuel is the highest quality product we found on the market for building muscle and increasing testosterone levels.

We found it rated number 1 on nearly all the review sites and in various videos.

The Benefits

Formulated for bodybuilders and weightlifters – TestoFuel uses clinically proven ingredients to improve muscle strength and size while simultaneously raising focus.

With more D-Aspartic Acid and Vitamin D3 than most T-Boosters out there, it is the strongest natural testosterone producer we could find.  It even contains Oyster Extract which is rich in Zinc containing over 59 combinations of amino acids, taurine, vitamins, minerals and other nutrients.

TestoFuel also helps free testosterone via Magnesium and doesn’t hide ingredients behind proprietary blends. Every ingredient is on show and effective.

The dosage level is good too, 4 servings throughout the day is one of the most effective ways to keep testosterone levels supplied and elevated.

The Snag

Oyster extract makes TestoFuel off limits for Vegans and Vegetarians.

Given the quality of this product, TestoFuel doesn’t come cheap – a month’s supply costing $69, however a three month supply supported by a ‘Risk Free’ money-back guarantee if you feel you haven’t benefited from the product.

TestoFuel also can only be purchased from the company’s website, but does ship internationally from the US and UK.


TestoFuel is a premium testosterone booster. It has a good nutrient profile full of proven ingredients key to the testosterone boosting process, and is dosed reasonably and effectively.

However due to the price, we recommend this product to guys who are already working out and actively seeking an extra advantage for making gains. You get what you pay for with – TestoFuel, make it count.

2. Prime Male


Aimed at men in their mid-thirties and above, Prime Male not only boosts T-levels – it also works suppresses estrogen production. Rising female hormones is a natural problem that men face as they get older.

The Benefits

Prime Male focuses on deterring estrogen as much as raising testosterone. This is to manage issues a lifter faces as they get older, whether they know it or not.

D-Aspartic Acid, Boron and Luteolin are key components to this product. Luteolin is a known aromatase (estrogen producing) inhibitor while Boron does a similar job but also helps D-Aspartic Acid with testosterone production.

Prime Male is also rich in aphrodisiacs and clinically proven ingredients to raise energy levels and libido like Korean Red Ginseng.

This product contains no proprietary blends and is dosed effectively at 4 pills spaced throughout the day for the best results.

The Snag

Prime Male is not Vegan or Vegetarian. It uses a gelatin capsule. However, the powder itself can be extracted and dissolved in water.

It is not recommended for men below 30 as aromatase inhibitors, and libido enhancers are unnecessary and offer no real benefits at that age.

Like TestoFuel, this product is also expensive and can only be purchased from the Prime Male website directly, however it does offer fast international shipping with a money-back guarantee.


The ingredient profile for Prime Male is great for men in their late 30’s and above, when the T-levels are naturally starting to droop. Mainly because of how it frees testosterone and suppresses estrogen.

However, it is not suited to everyone – guys below thirty have more to gain on products that focus less on reducing estrogen.

If you’re above thirty and want get back the edge that comes with youth, we recommend purchasing Prime Male.

3. Cellucor P6 Black

cellucor p6

Cellucor’s P6 Black is a testosterone booster recently returning to the market after a reformulation. The changes have been well received – there are high ratings online, and the product enhances cognitive function as well as testosterone.

The Benefits

P6 Black is aimed at guys looking to put on more strength and size with the added bonus of heightened mental focus.

It uses D-Aspartic Acid, Vitamin D3 and a range of nootropics to help with cognition in the gym. This helps strengthen both the body and the mind.

There is a steady supply of zinc and magnesium in this product to help free testosterone and decrease SHBG.

The Snag

Unfortunately P6 hides it’s D-Aspartic Acid beneath a proprietary blend – this makes it difficult to know how effective it will be.

Also the Vitamin D3 is lower in comparison to the others in this list.

The servings also happen all at once either 30 minutes before a workout or at breakfast on off-days from the gym. This will not keep T levels boosted throughout the day as they require consistent dosing.


P6 Black contains a lot of the right ingredients and is constantly praised in online reviews. However, many of those ingredients are under-dosed or hidden through a proprietary blend. This product also needs to revise it’s serving suggestions.

That said, it is widely available online with many retailers offering satisfaction guarantees should you change your mind about the purchase.

5 Lifestyle Changes for Maximum Benefits

Testosterone boosters work best when you work with them. Exercise, healthy diet and constantly pumping weights will really help get the most out of this booster. If you’re not already doing that – start. But it doesn’t stop there. Other steps can also be taken to lower estrogen and maximize your T levels:


chocolate-protein-Shake1Postpone the Protein

Cut down on the brotein. As we touched on earlier, if your daily intake is over 0.77 – 0.82g/lb you may not be utilizing all the nutrients that you’re taking in. This can lead to dramatic increases in cortisol and SHBG levels – killers of testosterone. It raises your fat gains and drops T levels, holding back your progress.

Study: http://www.ncbi.nlm.nih.gov/pubmed/3573976


sugar-cubesYou’re sweet enough
Sugary foods are a sure-fire way to slow your progress. Lots of sugar raises blood glucose- to absorb this, the body releases insulin. Eventually the body gains a tolerance to the Insulin and it can no longer absorb as much as it used to – so more is needed. This is known as insulin resistance and it releases a lot of cortisol and stress hormones throughout the body to deal with the problem. This lowers T levels significantly.

Study: http://care.diabetesjournals.org/content/28/7/1636.long


deadlift stickmanBig Three = More T

It main sound obvious, but working out large muscle groups releases a lot more testosterone into the body. The harder you workout – the more muscle needs to be repaired. This leads to an increased production of more growth hormone and testosterone to be released throughout the body.

Study: http://www.ncbi.nlm.nih.gov/pubmed/2796409


Don’t drink

Drinking heavily has also seen to cause lower testosterone. If you’re a beer drinker, you’ll find yourself gaining a higher estrogen count due to the phytoestrogens in the hops used to create it. It’s also been found that alcoholics have lower T-levels than average guys – regardless of their liver function.

sunshineSun Up
As we’ve established, Vitamin D is a powerful hormone – particularly D3, a good way to get more of it is to step outside in the sun. However, if you live in a particularly overcast country we suggest you look into one of the above products.

Overall Conclusion

From our research, we can confirm that TestoFuel is the best choice for a T-Booster with clinically proven ingredients and servings. It is the most effective one on the market for building muscle.

Prime Male on the other hand, has a strong nutrient profile but is best suited to older guys due to it’s estrogen suppressing capabilities.

Making some simple lifestyle changes could make all the difference to your T-Levels too. Little things like cutting down on alcohol and proteins are all valid methods of raising testosterone, with some of the more major methods being cutting back on sugars and lifting heavy.

So if you want to get big, focus on your raising your test levels today. You will see a whole load of benefits.

Disclaimer: Attempt at your own risk. The effectiveness and safety of these methods comes down to your individual biochemistry. Always consult a doctor before taking supplements or starting any new diet or exercise regimen.
