By Nader Qudimat / Sep 18, 2017

You've seen it before.

That one or group of guys in the gym who look like they are getting jacked by the rep.

They could be taking a bunch of good supplements or they could just simply be getting juiced up with steroids and testosterone injections.

Whatever it is, they simply seem to be making much more progress than you are. 

When it comes to building muscle, you can't do it without a proper plan for diet and training.

Because eventually those two will be the main factors for your testosterone levels. 

You can only get so far if your testosterone levels are below average.

You can complain about the horrible genetics that you have or you can do something about it. 

Benefits Of High Testosterone Levels

Having optimal testosterone levels have so many benefits.

You'll not only be able to build more lean muscle, you'll also experience better mood and have a better sense of well-being.

It's like having a key to reaching your potential.​

Many problems can be prevented by having optimal testosterone levels.

As a natural bodybuilder, or one that just needs a good PCT, you'll always have your test levels fluctuating when you have many factors come into play like stress, diet, and exercise mainly.

The Best Testosterone Boosters That Work

Buying Guide: Testosterone boosters

Purpose: Find a testosterone booster that works.

Must be high quality ingredients that are aimed to help the user.

Test boosters must live up to it's claims.

No hype or marketing B.S. Just test boosters that work. 

While you may be better off buying steroids than wasting money on most testosterone boosters, these supplements actually contain ingredients that'll not only enhance your test levels but keep your estrogen under control.


  • 1g Fenugreek Seed Extract
  • 1g Damiana Leaf
  • 1g Ashwagandha Root Extract 5:1
  • 500mg Quercetin Dehydrate
  • 500mg Diindolymethane (DIM)
  • 200mg Eurycoma Longifolia Root 100:1 Extract

This is the man who brought you Pre-Jym...

While Jim has been stirring up drama in the industry, his products are still strong and work well. 

Alpha Jym ​is a solid testosterone boosters (can be used as a estrogen inhibitor) that is built from 6 fully dosed ingredients. 

It starts off by using Fenugreek, a strong double dose of it but follows up with an unproven ingredient for increasing test levels; "damiana leaf"​, though it may help decrease estrogen levels. 

Of course, what's a test booster without ashwagandha.

It's a strong anti-anxiety ingredient which not only decreases stress but helps promote optimal testosterone levels.

It ends the formula with DIM (diinolymethane), which is known to decrease estrogen and quercetin​ to enhance fat loss. 

All in all, Alpha Jym should live up to it's name though it seems to be more of a estrogen-inhibitor, it should still be a solid test booster for beginners and skinny folks alike. ​


  • Well rounded formula
  • 36 grams of active ingredients per serving
  • Perfect booster if you are 30 or older
  • Doesn’t require PCT (estrogen inhibitor)
  • Reduces body fat and increases libido
  • Generous dose of Ashwagandha (increases testosterone)
  • Twice a day dosing (simple)
  • Can be used by women if they are not pregnant or expecting to be (Fenugreek is great for women)


  • Expensive (but well rounded supplement)
  • 500mg Fenugreek has little to no effect on testosterone levels (but great if you’re experiencing hair loss)


  • 1g L-Carnitine L-Tartrate
  • 500mg PrimaVie Shilajit (Ayurvedic, standardized to 50% Fulvic Acid)
  • 300mg Spilanthes Acmella
  • 200mg Eurycoma Longifolia 100:1

If you know Marc, then you either love him or hate him. 

It does not matter what you think of him, because his supplements are generally true to their claims.

Take Insurgent for example, it was recently released and it's being marketed as a super potent libido and testosterone booster.

Unlike most test boosters though, this doesn't have a long list of random, and underdosed or any prop blends for that matter.

All the ingredients are not only disclosed but they are fully and clincally dosed to do what it's suppose to do.... enhance testosterone levles.

It starts off with an unusual ingredient that isn't used much in test boosters; l-carnitine l-tartrate.

It's mainly used in supplements like intra workouts or pre in order to enhance endurance and recovery.

A gram is in here to enhance the production of hormones (testosterone) to optimal levels.

The other 3 ingredients in here will further enhance your anabolic state.

PrimaVie Shilajit (aka Ayurvedic, standardized for 50% fulvic acid), this ingredient will enhance muscle recovery and repair by enhancing a muscle's 'pliability'.

There's also a new ingredient in here that you may see blowing up in the supplement industry and that's "spilanthes acmella".

With 300mg of this in Insurgent, it's been proven in studies to increase testosterone levels in just 28 days.  


  • Increases muscle mass and testosterone production
  • Reduces cortisol levels and estrogen levels
  • Uses a new but proven test boosting flower (Spilanthes Acmella)
  • Enhances muscle growth and recovery
  • Improves blood flow and increases androgen receptor density in muscle cells (increases testosterone production)
  • Increases strength, size and performance
  • Can be stacked with Barracuda (contains DAA)
  • Aggression and mood may be enhanced


  • May not increase libido
  • Expensive (You get what you pay for)


  • 600mg KSM-66 (Ashwagandha)
  • 300mg Longjack Extract 100:1
  • 108mg DIM (3,3’-Diindolylmethane)
  • 100mg TestoSURGE (Trigonella Foenum, Graecum)
  • 490mg ZMA Complex
  • 61mg XD Delivery Technology (BioPerine, Astragin, Fumarate, Sodium ALA, Succinate)

Once you hit a certain age (usually around 30), you’ll begin experiencing some drops in testosterone levels.

This isn’t what you want if you’re trying to build muscle and want to keep the motivation high and strong.

So Blue Star has created an awesome test booster, Status.

While the bottle looks shiny and we like shiny things (who doesn’t?), the real reason this is on this list is because the formula is well put together with clinical dosages and scientifically proven ingredients.

Just look at the ingredients above.

It starts with Ashwagandha, a stress and cortisol reducer that can increase LH (Luteinizing Hormone) while simultonously reducing FSH (Follicle Stimulating Hormone).

That alone will put you in a solid foundation of an anabolic state.

Longjack is in most of the test boosters listed here as it has the ability to increase testosterone levels and libido.

Expect better hormone regulation, body composition and better overall sexual health.

DIM, aka 3,3’-Diindolylmethane, has estrogen reducing benefits that can also increase 2-hydroxyestrone (good estrogen).

Instead of just using Fenugreek alone, it takes advantage of a patented blend that also includes trigonella foenum (Testofen).

Studies have shown that this blend can increase creatine uptake, anabolic activity, testosterone levels as well as decreasing body fat.

Status is not only a test booster as you can see, it can also increase performance and strength.

ZMA is also included (Vitamin B6, Magnesium and Zinc), minerals that are usually depleted with intense exercise but are important for testosterone production.

And finally to ensure full delivery of those ingredients, it includes a XD blend that includes black pepper, fumarate and succinate.

Status is made to put you in an anabolic environment while decreasing cortisol and estrogen.


  • Increases performance and endurance
  • Clinically dosed ingredients that are proven to increase testosterone levels
  • Improves sleep and libido
  • Increases muscle mass while decreasing fat storage
  • Aggression, hunger and creatine uptake are all increased
  • Boosts testosterone levels and inhibits estrogen
  • Perfect for those over 30 years old
  • Contains basic minerals that increase testosterone production


  • Expensive (you get what you pay for)
  • Takes 2 weeks to notice difference (as with most test boosters)


  • 1.4g M-OXO (Coleus Forskohlii), Tongkat Ali, ALCAR, Naringenin / Hesperidin, Quercetin
  • 1.4g Maca, Puncture Vine, Safed Musli,
  • 700mg Muria Puama, Stinging Nettle, Dodder Seed Extract, Fenugreek
  • 500mg Beta Ecdysterone, 20-Hydroxyecdysone, 5-Methyl-7-Hydroxy-Isoflavone-Ethylcarbonate Ester, and Ipriflavone

From the start to the end of those ingredients, Thrust looks like a hardcore booster, wouldn’t you agree?

It might as well be the finest modern test booster coming straight out of Canada.

Thrust features 4 prop blends that consist of proven test boosting ingredients that can increase strength, muscle mass and drive.

The first ingredient is extracted from Coleus Forskohlii and studies have found this ingredient to increase testosterone production by copying the action of luteinizing hormone (LH) and raising levels of cAMP.

Next up is Tongkat Ali root, more commonly referred to as Long Jack and extracted from Eurycoma Longifolia.

This libido boosting compound can increase lean muscle mass and strength in less than 5 weeks.

ALCAR is usually never seen in a test booster but it’s in here, we assume, to prevent test levels from dropping due to stress.

The next 3 ingredients, Narigenin, Hesperidin and Quercetin, can inhibit estrogen and can prevent testosterone levels from declining.

Since we’ve now covered ingredients that can increase testosterone levels, the next blend will help keep those test levels increased for a longer period of time.

Maca helps prevent DHT levels from raising (a byproduct of increased testosterone).

Puncture Vine, aka Tribulus terrestris, is a libido and virility booster but it’s mainly great because it can increase the androgen receptor activity in the brain.

The final herb of this blend is Safed Musli, a adaptogen and aphrodisiac that can increase sperm production.

The next blend optimizes testosterone levels.

Muria Puama is usually used as a nerve tonic and can help with erectile dysfunction.

Stinging nettle, just like Fenugreek, is an ingredient used in hardcore test boosters, can stop SHBG (Sex Hormone Binding Globulin from wasting testosterone.

Fenugreek is another herb that’s been proven to increase libido and prevents DHT from being released and converted from testosterone.

The final and last blend consists of ingredients that are known as “ecdsteroids”, which are similar to androgen in structure.

Though it is not researched much, it’s been shown to produce testosterone like effects so it’ll get the body thinking that it is receiving more testosterone.

As you can see, all the ingredients work in synergy to produce, prolong and optimize testosterone levels while only using herbs and ingredients that are backed with studies.

Whether you’re using this for the gym or the bedroom, you’ll definitely notice the effects from the very first week or two.

Overall, Magnum has produced an impressive formula here.


  • Increases strength, lean mass and endurance
  • Decreases fat storage
  • Boosts libido and cognition
  • Prevents testosterone levels from decreasing
  • Stops testosterone from being converted into DHT
  • Prevents prostate growth
  • Inhibits estrogen (No PCT needed)

  • 1.2g Fadogia Agrestis PE
  • 1.2g Divana-Plex (Extracted from Stinging Nettle)
  • 695mg KSM-66 (Ashwagandha Root Extract)
  • 500mg Eurycoma Longifolia (Longjack)
  • 200mg PrimaVie Shilajit (50% Fulvic Acid)
  • 200mg Boron Citrate
  • 100mg Mucana Pruriens SE

No natural testosterone booster comes close to a steroid cycle, but most are formulated with poorly picked ingredients that have absolutely no studies to back them up with.

M-Test has earned itself a reputation of being a strong test booster that is formulated with patented (and expensive) ingredients to support and increase muscle growth, libido, performance and strength.

While CEL (Competitive Edge Labs) is not a brand you’d see at your everyday supplement store, they’ve earned the trust of the bodybuilding community as they are using fully transparent labels with scientifically backed ingredients.

Fadogia Agrestis is the first ingredient and studies have found this plant to increase testosterone and libido as its high in saponin (it increases LH, Luteinizing Hormone).

One of the all-star ingredients that is featured in M-Test, is Urtica Dioca, which is extracted from stinging nettle.

It’s able to increase testosterone in the blood as well as having the ability to protect prostate from complications that occur with DHT, a byproduct of testosterone that does nothing good.

Ashwagandha root extract is the next ingredient here, and it’s in a patent extract form of KSM-66.

You probably noticed this ingredient many times already in the test boosters in this list but it’s there for good reason.

Ashwagandha can help you remain in an anabolic environment as it can decrease cortisol.

Longjack, aka Eurycoma Longifolia, is a common ingredient for strong natty test boosters as it can help increase lean mass by increasing testosterone production.

PrimaVie is another patent ingredient that is made from Himalayan Shilajit.

Its standardized to 50% fulvic acid because it can increase the absorption of the other ingredients.

The main benefit of this ingredient is that it can increase muscle growth by speeding up the repair process that occurs after hard training.

An essential mineral, but usually underrated and underused, Boron can increase testosterone while simultaneously decreasing estrogen after only 7 days!

Last but not least, two growth hormone boosting ingredients that are combined together, Mucuna pruriens and l-dopa.

This combination doesn’t only increase dopamine product but it also promotes the production of growth hormones while decreasing prolactin.

Everything in this test booster is disclosed, clinically dosed with scientifically backed ingredients.

You’ll rarely find a test booster like M-Test and if you get the chance, give it a try.

AlphaMax XT is made to increase muscle growth and tesosterone while decreasing estrogen and providing the right vitamins and minerals to further support performance.

Performax has solid pre workouts and recently, they've finally released a solid muscle builder. 

It has a large number of testosterone enhancing ingredients ranging from stinging nettle​, mucuna pruriens, eurycoma longifola to estrogen / cortisol controlling ingredients like ashwagandha, dehydroabietic acid (DHAA) and coleus forskohlii. 

DHAA is an interesting ingredient here (aka Ahydroabietic Acid).

Inhibiting and limiting estrogen production, it’s able to act as a potent AI, leaving testosterone more readily available as it wouldn’t convert to estrogen.

AlphaMax XT doubles as a fat burner as coleus forskohlii is able to stimulate muscle synthesis and BMR.

Another research backed ingredient is Ferulic acid, this powerful compound to increase muscle mass, recovery, strength and overall performance in the gym and AlphaMax XT contains the exact amount used in the studies.

Olympus Labs is constantly releasing hardcore muscle building products that use full, research-backed, clinical doses. 

They don't just release new stuff, they also improve existing formulas like their Conqu3r Unleashed is about to be replaced with a new pre workout Re1gn which will contain a new stimulant along with tasteless theacrine.

Test1fy is Olympus's answer to testosterone optimization.

This formula consists 8 fully and clinically dosed ingredients that'll not only boost testosterone but help maximize your muscle gains and performance. ​

Beginning with 3.2 grams of Anacyclus Pyrethrum, an ingredient known to be a male vitality and virility enhancer.

It's mainly here to enhance male virility and libido. 

There's 675mg of ashwagandha root (5% standardized for withanolides) to help increase testosterone levels by increasing serum levels of luteinizing hormone testosterone ​while decreasing follicle stimulating hormone levels. 

Decreasing stress and anxiety, Ashwagandha is able to help maximize growth hormone output as well as testosterone production.

There's ​7 other ingredients in here, all to optimize testosterone levels. 

Containing a full spectrum of ingredients, ranging from testosterone optimizers, to estrogen / cortisol control, Test1fy is an excellent test booster.

Finding a natural testosterone builder that actually works and helps pack on mass is impossible.

But Antaeus Labs has made it possible with TITAN, their powerful and simple looking anabolic muscle builder and test booster.

This is a company that likes to use novel ingredients that actually work so there’s very few that can provide top quality supplements while living up to their claims.

TITAN is an all natural muscle builder that uses two simple but strong compounds; Shilajit and Tomatidine.

You may be familiar with Shilajit, a bioactive of fulvic acid that can increase the absorption of ingredients its combined with and it has the added benefit of increasing testosterone production.

Now the new muscle builder, Tomatidine is regarded as a plant-based steroid.

It comes from the tomato plant but the research is promising (though the cost may not be attractive).

This natural muscle builder can:​

  • Activate mTORC1 signaling and increase skeletal muscle
  • Increase performance and delay fatigue
  • Stimulate muscle protein synthesis Speed up recovery and reduce catabolism
  • Improves cardiovascular health

TITAN will increase mTORC1 production which results in more muscle growth while keeping catabolism at bay.

And with the addition of Shilajit, testosterone production be higher than usual.

This alone is a benefit that is greatly appreciated by natural bodybuilders who are either drug tested or do not want to take anything with potential side effects.

So far, Antaeus Labs is the only company that offers this in a supplement but it looks well worth trying as the studies and benefits look promising.

And just like Epicatechin, another new muscle building ingredient, the price will remain high until it becomes more commonly used.

Whether you’re a natural lifter or a drug tested gym rat, gains are going to come a little easier with TITAN.

If you’re on a budget, try the other test boosters here.

  • Disodium Phosphate, Laxogen

Fusion Supplements are known to make hardcore supplements that are backed with scientifcally proven ingredients.

Traditionally, test boosters contain various herbs and blends to increase and prolong testosterone levels.

This here is something beyond what you would expect.

Progenadrex is formulated to increase muscle growth by using ingredients that maximizes nutrient uptake to promote more lean muscle mass.

It uses Anacyclus to increase the production of testosterone.

In fact, research shows that it doubles the sythensis of testosterone

Another purpose of this ingredient is that it’s able to triple the size of muscle cells by driving more glycogen into them (hence why creatine and R-ALA is coming up next).

Acting as a testosterone catalyst, Laxogenin doubles testosterone production and increases muscle mass by stimulating protein synthesis.

So far, this formula is able to increase glyocgen storage, muscle protein synthesis and testosterone levels.

And we’re not even done yet.

Creatine HCL is here to drive more glucose into muscles and is enhanced with the help of R-ALA and Di Sodium Phosphate.

There’s also synergy between R-ALA and Laxogenin as it’s an anti-inflammatory compound that can increase protein synthesis.

Usually, you’d have oily skin from all of these effects but Biotin is included to counteract that.

Made for muscle growth, Progenadrex is one hardcore test booster that uses an impressive and unique formula based on proven and studied compounds.

Whether you’re looking to get bigger or swole, you’ll pack on mass quicker with Progenadrex.

It’s also a great way to get pumped as it’s made to increase the size of muscle cells.

You need to increase your carb and water intake to really take advantage of the benefits here.

You’ll also want to keep cycles to 4 weeks and stick to more frequent and shorter training sessions.

We can see this being ideal for the skinny guy training struggling to pack on size but you do need to know what you’re doing in order to take full advantage of this.
