Quick Take: For a brand named Fundamental Sound Science to produce a supplement with a label as clean as this, it’s tempting to buy a bottle of Xtreme Test under the notion that it might be supported by some kind of doctor but let me tell you this – don’t believe what you see on the label. Instead, try reading a review (like this one!) and maybe you’ll learn a few things beyond what the bottle tells you. Ready to know the truth? Let’s get started.
- A product of Fundamental Sound Science, Xtreme Test is advertised on Amazon to be a “male testosterone & libido booster”
- A single capsule contains a 742 mg prop blend with 8 natural ingredients
- The top priority among these ingredients being Horny Goat Weed (a non-testosterone boosting herb)
- Including Horny Goat Weed, half the list of Xtreme Test ingredients don’t boost testosterone
- Looks more like a libido/prostate health supplement rather than a test booster
- Available to buy on Amazon but I couldn’t find it on GNC.
Xtreme Test Ingredients
|Proprietary Formula||742 mg|
|Horny Goat Weed Leaf Extract (Epimedium Grandiforum), Tongkat Ali Root Extract (Eurycoma Longifolia), Saw Palmetto Fruit Extract, Orchic Substance, Wild Yam Root Extract, Sarsaparilla Root Extract, Nettle Root Extract and Boron Amino Acid Chelate|
Xtreme Test’s T-Boosters & Other Ingredients
Horny Goat Weed – Doesn’t boost testosterone per se but it does mimic its effects with higher sex drive being the most prominent.
Tongkat Ali – A natural libido booster that research shows may also increase “free” testosterone while lowering levels of cortisol. This combo could be ideal for bodybuilding.
Saw Palmetto – Particularly beneficial for prostate health by decreasing levels of the androgen DHT. This could also potentially mean boosts in testosterone.
Orchic Substance – Bull (or cattle) testicles is what this is and no, it doesn’t boost testosterone. That’s all a myth at this point.
Wild Yam – Contains the steroid precursor DHEA. However, Wild Yam supplements don’t seem to have the same effects as DHEA so don’t count on this to boost testosterone.
Sarsaparilla – May be beneficial for libido but it doesn’t look like it can boost testosterone.
Nettle – Adds another layer of prostate protection by also lowering levels of DHT. In addition, Nettle also inhibits aromatase and SHBG activity and may therefore boost levels of “free” testosterone.
Boron Amino Acid Chelate – One of the manliest minerals given one of its more potent forms. Boron can boost both total and “free” testosterone as well as counterbalance levels of estrogen.
Xtreme Test Directions
Each serving of Xtreme Test consists of 1 tablet and as instructed by Fundamental Sound Science, we are to take 1 tablet in the morning and another one before exercise for a total of 2 servings per day.
Since we’re supposed to take 2 servings of Xtreme Test per day, the total dosage also gets doubled from 742 mg to 1484 mg. This is important to take note of since Fundamental Sound Science designed Xtreme Test to be a proprietary formula which means the specific dosages of the individual ingredients aren’t disclosed.
That said, 1484 mg for 8 ingredients isn’t really all that bad but it’s not very good either. Even worse is that half of the Xtreme Test formula doesn’t really do sh*t for testosterone (e.g., Horny Goat Weed, Wild Yam, Sarsaparilla, Orchic Substance).
To be fair, Sarsaparilla and especially Horny Goat Weed do offer decent boosts in libido. With Tongkat Ali added to the equation, I can say as early as now that the primary benefit of Xtreme Test is a heightened sex drive.
Tongkat Ali, along with Stinging Nettle, Saw Palmetto, and Boron are notable testosterone boosters but their benefits seem more evident in the older population. You see, Tongkat Ali’s test boosting manifests better in men with already compromised levels of testosterone (i.e., men above their 30’s). The older population also tend to have more problems with their prostate due to excessive levels of DHT and that’s where Stinging Nettle and Saw Palmetto come into play.
I’m not saying young men can’t benefit from Xtreme Test though as it does seem to have mild benefits for muscle growth and “free” testosterone but overall, Xtreme Test looks more like a libido/prostate health supplement more than a powerful testosterone booster.
Does it Work?
It probably does but with the proprietary nature of Xtreme Test, it’s really hard to accurately gauge how much it’ll work. However, in my opinion, whatever the benefits may arise from this supplement will be mild regardless.
The low total dosage of the Xtreme Test formula just won’t allow it to be mentioned alongside the most powerful supplements but it may still have its value. At just below $18 on Amazon, this could be a cheap but mild fix to low libido, prostate problems, and declining muscles.
Monkey see, Monkey Do
I felt like I’ve written other reviews with nearly identical content as Xtreme Test so I scanned through my previously reviewed test products. There, I found these two:
Those two supplements share the same exact proprietary formula as Xtreme Test. The only difference is that Prime Test has the addition of Calcium.
- Cheap – This has to be the best thing about Xtreme Test
- Feel-goods – Higher sex drive and a protected prostate give you the feeling of rejuvenated vigor without actually boosting so much testosterone
- Reputation – The ratings on Amazon are generally high. There’re just 11 customer reviews though. No reported side effects either.
- Boron and Tongkat Ali – The only two ingredients on here that you can really count on for boosted test
- Proprietary – Not being able to see the individual dosages suck.
- Weak – Thanks to poor total dosage and poor ingredient selection
- Unoriginal – I don’t know which test booster came first but Prime Test, Testorex, Xtreme Test, and maybe many more others are basically just copies of each other.
The Bottom Line
Despite what its name suggests, Xtreme Test is nowhere near extreme nor is it even fundamentally sound. Honestly speaking, the name “Mythological Science Weak Test” seems more appropriate. They have their poor dosage and poor ingredient roster to thank for this but, to their credit, it does offer libido boosts and prostate protection at just under 18$ so there’s that.
