USN 19-Anabol Testo Review


USN is a respect fitness brand and 19-Anabol Testo has some good online reviews, so we thought we’d take a look.

19-Anabol Testo claims to:

  • Support and maintain testosterone levels
  • Help you “avoid a negative impact on your training”
  • Allow you to work towards your training goals
  • Increase performance
  • Support “normal fertility and reproduction”
  • Reduce fatigue

At the moment, nothing stands out about this T-booster. And as USN 19-Anabol Testo costs just $25, we’re having a hard time believing it’s anything special. To find out whether we’re wrong, read our USN 19-Anabol Testo review below…

About The Company

USN – or Ultimate Sports Nutrition – claims to be the “market leader in sports nutrition.”

It also says it prides itself “in offering only the best sports supplementation and expert nutritional advice.”

The company’s “exciting journey” began back in 1999, when it was formed by Albé Geldenhuys, a mountain bike enthusiast.

USN brand ambassadors include IFBB Pro Ryan Terry, Fitness Personality Mark Hoban and motorbike racer Ivan Lintin.

19-Anabol Testo Ingredients and How They Work

19-Anabol Testo doesn’t contain any proprietary blends – which is a great start.

Recap: Proprietary blends list ingredients, but hide the dose of each one. This is bad because it gives you no way to see how effective (or potentially unsafe) each of these ingredients may be.

But aside from a few great ingredients, this supp also appears to use a few dubious ones.

See for yourself:

USN 19-Anabol Testo ingredients

Vitamin B6

You’ll find Vitamin B6 in beef, fish, liver (and other organ meats), and non-citrus fruit. Despite this, not getting enough of this vital nutrient can reduce your testosterone and raise estrogen (the female hormone).

This in turn makes it harder to gain muscle, lowers your sex drive and induces fatigue. As a result, it’s great to see Vitamin B6 in this supp.

However, we’ve found 5mg-7.5mg of B6 to be optimal. 19-Anabol Testo contains 15mg, which is up to three times too much.

As there’s only so much space in any supplement, this one would be better if a lower dose of B6 made room for other important T-boosting ingredients.


Magnesium sources include whole wheat, almonds, cashews, beans and edamame, among many others.

But in spite of the mineral’s presence in a number of popular foods, magnesium deficiencies are common in the western world. As nuts are high in fat and edamame may lower testosterone, it would be wise to get a good dose of Magnesium in a supp.

Magnesium supplementation helps lower blood glucose. High insulin levels can hamper your body’s ability to produce T, so it follows that Magnesium also helps you gain muscle and expand your capacity for aerobic exercise.

In fact, a great deal of research proves this is the case.

How much Magnesium do you need?

In our experience, 100mg-200mg gives you the best results. In addition, the tolerable upper limit (UL) of magnesium is 350mg. This is the point at which it may become toxic and cause side effects.

With this in mind, the fact that 19-Anabol Testol holds 450mg – 100mg above the UL – is worrying.

Sources of Zinc include oysters, lamb, pumpkin seeds and beef. At the right dose (10-30mg), this micronutrient is both an aphrodisiac and a T-booster. It’s also an aromatase inhibitor, which means it can reduce levels of estrogen in your body.

As this female hormone can interfere with your body ability to produce T, using Zinc to reduce estrogen helps you pack on muscle.

And because the body loses Zinc through sweat, supplementation is vital for athletes who don’t get enough of it in their diets.

Testofen (Fenugreek Seed Extract)

Testofen is a’patented’ form of Fenugreek. The herb helps lower levels of the Sex Hormone Binding Globulin (SHBG), which strips free T of its power to help you gain muscle.

As it’s found almost exclusively in Indian food, it can be difficult to get a decent T-boosting dose of Fenugreek without eating a lot of curry.

But while tasty, curry can be high in fat, which is no good if you’re trying to get cut. For this reason, it makes sense to get more Fenugreek in a supp.

Trials show Fenugreek not only boosts muscle gains, but helps you cut fat and enhances your sex drive.

Testofen vs Fenugreek

Testofen is nothing more than a brand name. Its makers say it’s a more potent form of Fenugreek, but it bases this on the findings of researchers with a vested interest in selling it.

The use of a brand name means Testofen costs more than plain old Fenugreek, even though they’re the same thing.

19-Anabol is a cheap supplement, so it makes us wonder a) why USN paid over the odds to use the branded version (if it did) and b) where else it cut corners to afford the branded form of this herb.

Our tests reveal the perfect dose of Fenugreek is 100mg. When it comes to doses, it’s important to find the perfect amount; too much is often just as bad (or worse) than too little. So as this T-booster contains 300mg, it’s likely that it won’t give you the results you’re looking for.

20-Hydroxy Ecdysterone

20-Hydroxy Ecdysterone is one of four popular ecdysteroids, along with ecdysone, ecdysterone and turkesterone. While all four ecdysteroids are very similar, turkesterone appears to boost T the most.

That said, ecdysteroids as a whole have no significant effects on testosterone, power output, or lean mass.

20-Hydroxy Ecdysterone isn’t even the most potent of these ineffective hormones. For this reason, we’re doubly dismayed to find it in this supp.


Otherwise known as Methoxyisoflavone, this compound is widely marketed as a bodyybuilding ingredient.

However, a lone study on Methoxyisoflavone (from 2006) showed the compound does not have any real effects on muscle growth, training capacity, or T-levels in general.

The limited research on this ingredient strongly suggests it’s useless – and no-one should expect you to hand over your cash for it. It’s sad to see this ingredient in a supp made by a respected brand.

Avena Sativa

Avena Sativa is the posh name for the common oat, widely found in oatmeal, muesli and granola. Some marketers will tell you Avena Sativa increases levels of the Luteinizing hormone (LH), which is a precursor to testosterone. Others may tell you it boosts sex drive.

Don’t listen.

As oats can lower cholesterol and prevent celiac disease, they are healthy. But there’s no proof oats affect testosterone or libido, either directly or otherwise.


7-Isopropoxyisoflavone is more commonly known as Ipriflavone. For reasons that are a mystery to us, some in the fitness world are touting the synthetic compound as a hot new ingredient for bodybuilders.

This claim is based on the presence of isoflavones in the compound, as well as research by a Hungarian named Doctor Laszlo Feuer. Dr Feuer found that Ipriflavone boosts T in various animals, which isn’t a surprise when you consider that isoflavones have a mild anabolic effect.

That said, there is no proof the compound boosts T in humans. More research also needs to take place to confirms Feuer’s findings.

As a result, we cannot condone the use of Ipriflavone in 19-Anabol Testo.


Bioperine is a patented – and common – form of Piperine, otherwise known as Black Pepper Extract.

It’s main purpose is to increase the bioavailabilty of different compounds – and it works well with Fenugreek to help boost T and libido.

But whereas this supp contains too much of most of its best ingredients, 19-Anabol Testo doesn’t have enough Bioperine (5mg) – we’ve found the optimal dose (in a T-booster) to be 10mg.

19-Anabol Testo Side Effects

Overall, 19 Anabol Testo is safe.

However, this supplement contains 450mg og Magnesium – this 100mg above the tolerable upper intake level for adults of all ages. This could be especially unsafe if you already get Magnesium in your diet.

Taking too much Magnesium can cause:

  • Diarrhea
  • Lethargy
  • Nausea
  • Vomiting
  • Irregular heartbeat
  • Breathing problems
  • Heart attack


  • B6, Magnesium and Zinc are important T-boosting nutrients
  • Fenugreek boosts T and enhances sex drive


  • Potentially unsafe amount of Magnesium (450mg is 100mg above upper tolerable intake level)
  • Too much B6 and Fenugreek
  • Testofen is just a more costly version of Fenugreek
  • No proof Avena Sativa can raise testosterone
  • No evidence Ipriflavone increases T in humans
  • Methoxyisoflavone is useless as a T-booster

USN 19-Anabol Testo Review Conclusion

USN 19-Anabol Testo contains some high-grade ingredients – and others that are either unproven or useless.

You’ll find the likes of B6, Zinc, Magnesium, Fenugreek and Bioperine in one or two of the best test boosters on the market. But the use of feeble ingredients like Avena Sativa and Methoxyisoflavone highlights this supp’s cheap price.

The low cost of 19-Anabol Testo also shines a dubious light on the use of Testofen – a costlier version of Fenugreek. Although we can’t say for sure, it’s likely USN had to pay over the odds for this form of Fenugreek.

This in turn makes us wonder how they cut corners elsewhere.

WAY TOO MUCH Magnesium

19-Anabol Testo contains 450mg of Magnesium – which is 100mg above the tolerable upper intake level. Tests show that taking too much Magnesium can lead to symptoms ranging from diarrhea to breathing issues, and even cardiac arrest.

Such issues may become even more pronounced if you already get Magnesium in your diet.

Our verdict

Due to the use of a number of useless ingredients, coupled with the overdosing of others, we advise you stay away from 19-Anabol Testo and look for a T-booster with ALL proven ingredients at the right doses.
