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.

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.

Steel Alpha AF is a jam packed test booster that will likely hit our top 10 list soon! Check it out.

Best Testosterone Boosters

While PreSeries Bulk is a pre workout, it has a testosterone blend that should be taken if you want to optimize test levels. 

With a blend of zinc, vitamin D3, boron citrate, it’ll not only help with test levels but it’ll also strengthen bone health, and help you build a strong foundation for maximum results in the gym. 

The test blend is only the extra to Bulk. 

It covers nitric oxide, strength and endurance with various but clinically dosed ingredients. 

And BCAA’s are included to help prevent muscle loss, think of it as insurance for muscle gains. 

If you’re taking a pre workout, then Bulk can be your 2-in-1, with a testosterone blend it’ll a versatile supplement to have in your arsenal.

PROS

  • Increases testosterone production
  • Enhances energy and focus
  • Prevents muscle loss

CONS

  • Only available at one source

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.

PROS

  • ​Increases performance and endurance
  • ​Clinically dosed ingredients that are proven to increase testosterone levels
  • ​Increases muscle mass while decreasing fat storage
  • ​Aggression, hunger and creatine uptake are all increased
  • ​Boosts testosterone levels and inhibits estrogen
  • ​Contains basic minerals that increase testosterone production

CONS

  • ​Expensive (you get what you pay for)

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.

PROS

  • Increases strength, lean mass and endurance
  • Decreases fat storage
  • Boosts libido and cognition
  • Increases testosterone levels and optimizes
  • Inhibits estrogen (No PCT needed)

CONS

  • A bit pricey

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.

PROS

  • Increase motivation and energy
  • ​Increases testosterone and growth hormone production
  • ​Decreases estrogen and prolactin
  • ​Lowers stress and anxiety
  • ​Protects and optimizes prostate health

  • A bit pricey

​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.

While it uses a big prop blend of test ingredients, various reviewers and forum posters have posted their testosterone results before and after taking Ape.

ZMA supplements are known to help with testosterone levels.

Zinc plays a vital role in muscle building but it is depleted with intense exercise. 

Taking in a ZMA supplement helps prevent deficiencies caused by exercise, and as a bodybuilder, you’ll need to ensure you’re getting these nutrients whether from supplements or diet. 

ZMO is different because it doesn’t use the traditional formula for ZMA (zinc, magnesium, vitamin B).

Instead, it uses zinc, magnesium and oyster.

Not only are they used at their full clinical doses, but they are included in their best, highest quality form.

Most ZMA supplements use poor forms which aren’t absorbed by the body. 

With ZMO, you’re getting the most out of it as the forms are highly bioavailable and easily absorbed.

It can also be stacked with other supplements like prohormones or other hardcore supplements to maximize and help make more aggressive gains.
