Real Science Behind Clinically Proven Gains In Testosterone

Don't settle for the effects of nature's curse. As men age, the natural production of testosterone begins to decline. This can start to happen significantly as early as age 25! This powerful hormone impacts muscle mass and strength, bone density, energy levels and of course libido. Overall it defines your virility and vigor – so why let that fade when you don't have to. If you want to feel young, strong and alive again or if you just want to take your workouts and sex life to the next level – you need to bring your testosterone levels back within the normal range.

How you ask? There's an all-natural way to ensure your body's production of testosterone does not drop, and to guarantee that the testosterone you are producing is utilized to the max and not wasted.

FORTITUDE – is the strongest legal test-boosting product on the market period. Formulated with ingredients backed by science, it is clinically proven to jack up your free testosterone levels by 98.8%, with noticeable effects in as little as 7 days.

The all-in one formulation of FORTITUDE also includes a built-in complex to reduce aromatase activity, and selectively modulate estrogen receptor sensitivity – to ensure that all that free testosterone gets utilized to the MAX!


Real Powerful Ingredients


This highly specialized extract of fenugreek seeds has been demonstrated to Boost Free Testosterone by Over 98.8%, safely and effectively.


This First-to-Market ingredient maximizes libido and testosterone output by elevating blood flow to the testes and actually improving sperm count and quality.


A recent scientific study demonstrated that supplementing with 10mg of elemental boron per day can increase free testosterone levels within 7 days.


This hyper-potent extract of Eurycoma longifolia root has a two-fold action. It elevates free testosterone levels by helping product more of its precursor hormone DHEA. Long Jack also helps suppress the activity of the Sex Hormone Binding Globulin (SHBG). SHBG levels increase in the blood with age, and this protein binds free testosterone and prevents it from actively providing any downstream benefits.


Aromatase is the enzyme that breaks down free testosterone and converts it to estrogen (female hormone, with negative effects for men). Therefore inhibiting this enzyme's activity is critical to ensuring that any elevation in natural testosterone production isn't wasted. Fortitude's combination of White Button mushroom extract and 7-methoxyflavone is 1-2 punch of nature's most potent and scientifically validated aromatase inhibitors.


FORTITUDE completes the all-in-one testosterone enhancement effect by including not only free testosterone boosters and aromatase inhibitors, but also natural selective estrogen receptor modulators (SERMs) to block the effects of estrogen at the cell receptor site. In the presence of a natural SERM, like those used in FORTITUDE (Caffeic acid phenethyl ester from bee propolis and resveratrol from Japanese Knotweed), estrogen cannot attach to cells and exert negative side effect like sensitive breasts, inflammation and even cardiovascular issues.

Formula 9/10

Honestly there's a lot of ingredients in here that I recognize and have stumbled across in other test boosters, this seems to be the best of each. The standouts from my newbie point of view are the Long Jack for test boosting and 7-Methoxyflavone for an AI.

ANS are probably my preferred overall brand at the moment and to be honest I trust their pic of ingredients and dosages.

Overall: 9/10

So after 4 weeks I have to ask myself what did I expect, and what did I get out of this?
I didn't get bloods so cannot confirm completely if my test levels were boosted. I can say that I got some pretty gnarly acne which only popped up during week 2 and was soon gone.
Performance wise it's a bit unfortunate due to changing my routine from 185 squat back to a higher volume full body plan.
I didn't feel much benefit recovery-wise however I've been battling off a cold that my wife and son are carrying, plus more heavy load from work, which in turn causes my diet to fluctuate.

What I can say is that I did manage to drop some inches from around my waist soon after taking. My belly fluctuates quite easily based on carbs and water weight but even so I was really happy to see.

I think that if the planets were all aligned and I stuck to my routine, and didn't feel crook, this would have really shone through for me. However I am probably going to run another bottle back to back (will assess finances first) to give it a full 8 week cycle as recommended.

The price at $89 for a full months supply is quite reasonable as well.

Once again thanks heaps to Xplosiv / and ANS.

I did a cycle of this hoping it would be the special sauce... sadly it was not to be. As a 41 year old male I made the assumption I would be relatively low-T; but despite that I had no noticeable increase in libido, aggression, 'alpha' feeling, or improvements in sleep or recovery on Fortitude. However I still give it an 8 overall because I honestly am not sure what impact, if any, it had on my strength. It certainly didn't lead to a blitz of new 1RMs... but long heavy workouts may have been a shade easier. At some point I would probably run another cycle to put it to the test (....unintentional dad joke) again. A note on the flavour: the Romans didn't call asafoetida (a main ingredient in "ferutest") 'devil's dung' for nothing... these caps give you pretty foul tasting burps, but you do kinda get used to it.

I have been taking this for well over a week now. In the past on testosterone boosting supps, I noticed I'm real tired in the mornings. From what some people have said, that's due to my testosterone already being elevated.... Awesome, not bad at 38

Out of respect for the trail and review (and I ain't giving away my supps!) I've been taking them for over two weeks, despite the tired feeling in the morning. I have noticed my need for extra "bedroom cardio" lately, without actually thinking about why. Well.....

I have a super accurate body composition analyser at my disposal, and that is showing some good gains in the muscle department since returning from a holiday where I trained to maintain, but lost about 500g muscle. This has since returned and a little more. For my frame I'm at the higher end of the natty spectrum so every slab of muscle is hard earned.

Thank you for the relationship enhancer!!

I don't think I can top SuppGurus review, however I have posted a more in depth review here -
I will mention that this product will definitely improve your sleep and obviously your libido.
I took this solely because I wasn't feeling 100%, and felt that it may be due to low level Test, turns out, my Test wasn't low at all, but it did increase however. Great product ANS, well done!

While I have just completed my first bottle, and most positive reports Ive seen are based on running 2 bottles, Im very happy thus far.

If sex drive is anything to go by, day 3 was when the "frisky" factor really kicked in! Usually that indicates testosterone has been booming!

Not sure if related but my long term elbow injury is improving and cant be sure if Fortitude has helped here? Increase testosterone can dramatically improve repair.

Great to see a list of clinically proven ingredients in the same dosages used in the studies along with a unique formulation- not just another me-too.

Another classic product from ANS

Don't get me wrong I've only been using this a couple of weeks, but I feel I've used it long enough to provide a good enough review!

My sleep has improved (almost like I'm getting to another level of deep sleep)Libido has gone through the roof, Recovery has improved (this good be partly attributed to biogro also)

Also note I'm feeling a lot more switched on when it comes to my workouts this could be from increased testosterone as I have naturally low levels, I remember the last time I felt this good from a testosterone booster was when I got my bloods done and my levels doubled.. So it's exciting stuff for Fortitude..

Have run Fortitude several times and I'm just starting another cycle of it to help fight the holiday poundage.

Every time I take it, I feel much more 'alpha'. I sleep better, I am stronger in the gym and have a faster recovery. Libido goes up too. All indications that Test levels are increasing.

The science with Fortitude is strong: it raises free test, blocks estrogen receptors (SERM) and block aromatization of test to estrogen. Excellent 3 in 1 all-natural product.

For me honestly, it's the strongest natural test booster, and I've tried other Testofen products as well as D-Aspartic acid. Nothing comes close.
