MFIT Peak Force: Testosterone, Strength, Power, and Brass…

MFIT Supps Peak Force

Testosterone, Strength, Power, and Libido in a Pill: MFIT Supps Peak Force is Here!

Since first bursting onto the scene at the 2019 Arnold, MFIT SUPPS has done an exceptional job of building their brand. Initially coming to us with fierce pre-workout formulas in Havoc and Trigger, they’ve continued to flesh out their product profile by diving into new areas within the industry. We need formulas that impact our health and fitness missions, regardless of what they may be!

As we age, this mission obviously becomes more difficult. The happenings of natural aging and the stresses of everyday life team-up to form a powerful foe. For men, maintaining proper testosterone levels is one of the more difficult challenges. Testosterone helps regulate hormonal function, strength, and overall vigor, so being able to ward off things that can attack it, such as aging or stress, is imperative.

MFIT Peak Force: Testosterone, Strength, and Power

The latest addition to the ever-growing MFIT family is Peak Force, the brand’s first testosterone-boosting supplement. Designed specifically to support optimal testosterone levels and raise strength and power output for those of us with declining testosterone, Peak Force uses an impressive complex to deliver exceptional effects. With a number of science-backed ingredients at clinical dosages, a signature quality of all MFIT products, Peak Force has the makings of an extremely powerful testosterone-boosting product.

In this post, we’ll break down all there is to know about Peak Force, focusing on its uses, ingredients, and potential benefits! Before we dive into this power-packed formula, make sure you’re subscribed to PricePlow for the latest supplement deals, news, reviews, and interviews!

MFIT’s Peak Force Ingredients

There are quite a few natural herbs and patented ingredients that can be useful in this case, and luckily for us, MFIT uses a variety of them in Peak Force.

  • PeakO2Ⓡ [Cordyceps militaris (Cordyceps), Ganodema lucidum (Reishi), Pleurotus eryngii (King Trumpet), Lentinula edodes (Shiitake), Hericium erinaceus (Lion’s Mane), Trametes versicolor (Turkey Tail)] – 1000mg

    MFIT SUPPS Peak Force Ingredients

    Peak Force has several ingredients we often see in test boosters, but several others that we don’t!

    PeakO2Ⓡ, the highly-praised mushroom blend from Compound Solutions, is not only the first ingredient listed in Peak Force, but also the blend that likely inspired the product’s name! Due to its ability to deliver wide-ranging benefits across various areas, MFIT was surely excited about this inclusion here!

    PeakO2Ⓡ is a medicinal mushroom blend that has grown increasingly popular in recent years. It incorporates multiple mushrooms in its formula, with Cordyceps militaris acting as the driving force behind the entire complex. The other five mushrooms also bring their own individual benefits to the table, as well.

    Interestingly, PeakO2Ⓡ typically finds itself contributing in endurance-based products – the blend has been shown to increase aerobic performance, delay fatigue, and increase peak power during prolonged bouts of exercise.[4] Thus, it sits as a leading endurance-improving ingredient in the industry. These effects are obviously desirable, but in a testosterone-focused supplement, is there a bit more to this blend than that?

    Mushroom-based testosterone support – Some additional studies:

    As it turns out, the answer to that question is a resounding yes! Looking at the individual components of PeakO2Ⓡ, there happens to be quite a bit of research that supports positive hormonal effects when consuming these mushrooms.

    • Cordyceps
      Cordyceps Militaris Benefits

      This incredibly-successful human study was actually done on a patented mushroom blend, named PEAKO2. Is cordyceps militaris really where the action’s at? We believe so.

      Cordyceps, the leading mushroom in PeakO2Ⓡ, may have some testosterone-boosting benefits to bring to the table, in addition to its effects on endurance and power. Research in mice cells have shown that cordyceps can stimulate testosterone production in a dose-dependent manner.[5] While the gains from this effect are obvious, we need to take these effects with a grain of salt – while encouraging, we’re looking forward to human-focused research on this effect!

    • Reishi

      Reishi has displayed properties somewhat similar to that of cordyceps, with science identifying the specific bodily mechanism it interacts with. Research has shown that reishi reduces 5-alpha reductase,[6] the enzyme that converts testosterone to dihydrotestosterone (DHT). DHT is a sex hormone that plays a critical role in inducing hair loss, and is overall somewhat problematic in older men. By inhibiting 5-alpha reductase activity, reishi works to limit DHT, keeping more free testosterone flowing throughout the body!

    • Cordyceps and Reishi: Testosterone boosts post-exercise
      PeakO2 Ingredients

      PeakO2 has six different mushroom species, but the primary one is Cordyceps Militaris

      The doses below are more than we’ll have here, but interesting nonetheless:

      In a study from 2014, researchers tested the effects of both cordyceps and reishi supplementation in male cyclists training for a race. Subjects were randomly assigned to three groups – one group received 1335mg of cordyceps daily, another 1170mg of reishi, and the final a placebo. After three months of supplementation, the researchers found some interesting results – following an intense cycling race, both medicinal mushroom groups had doubled their testosterone-to-cortisol ratio.[7] Raising testosterone while lowering cortisol, the hormone secreted when we’re stressed, during exercise brings with it multiple benefits – more intense training, better recovery, and elevated endurance.

      Ultimately, this study concluded that both cordyceps and reishi can be potentially used to fight overtraining, something anyone who loves exercising knows can do damage on your hormones!

    PeakO2Ⓡ delivers on both the macro and micro levels – the blend itself has shown some impressive endurance and power-based abilities, while the individual ingredients have displayed testosterone-boosting capabilities. Regardless of which potential benefit you value most, one thing is for certain – PeakO2Ⓡ is a phenomenal inclusion here!

  • KSM-66Ⓡ [Ashwagandha (Standardized Extract of Withania somnifera root to contain Min. 5.0% Withanolides)] – 600mg


    KSM-66 bills itself as the World’ Best Ashwagandha… and we don’t disagree!

    From one unconventional hormonal aid to one of the industry’s most popular, ashwagandha is yet another powerful ingredient included in Peak Force. Coming from Ayurvedic medicine, this herb has long been touted for promoting an unprecedented balance between the body and mind. It seems to have an array of benefits, with its most potent pertaining to hormonal health.

    Reduces stress….

    The vast majority of research regarding ashwagandha is focused on its interactions with cortisol, the stress hormone. High levels of cortisol have been linked to poor blood insulin response, weight gain, anxiety, and yes, poor testosterone production. Therefore, maintaining proper cortisol levels is key for promoting overall health. Luckily, ashwagandha may be one of the most effective herbs at doing just that! We discuss much of the cortisol reduction in our MFIT Stress-66 post as well.

    Modern science has backed up what those in Ayurvedic medicine have been claiming for centuries. In a study from 2012, scientists administered 600mg of ashwagandha daily for 60 days to health subjects. At the end of the study, this double-blind placebo study found that those given the herb had reduced cortisol levels by 28%, whereas the placebo only did so by 8%.[8] In case you needed further evidence, a similar study found an almost identical 30.5% reduction in cortisol following chronic supplementation of 500mg daily![9]

    …which creates a testosterone-friendly environment!

    Ashwagandha Strength Gains

    These are some serious strength gains on the big lifts!

    Now, to truly understand the power of these cortisol-reducing effects and its relation with testosterone, we can cite additional research that studied that relationship while incorporating ashwagandha. In 2015, a double-blind placebo study assigned 57 young men to two groups – one was given 600mg of ashwagandha per day, while the other was given a placebo. After eight weeks, the group taking the herb had increased testosterone levels by 15%.[10] Note that these were healthy men between the ages of 18 and 50 – these effects could potentially be more pronounced in someone in their 40s struggling with their testosterone!

    KSM-66Ⓡ is arguably the most high-quality form of ashwagandha extract on the market – it contains 5% withanolides, the bioactive compound within ashwagandha that scientists believe is responsible for the herb’s abilities. KSM-66Ⓡ ashwagandha is an industry-favorite, and as evidenced by MFIT Stress-66, MFIT is too! This ancient herb is a powerful anti-cortisol agent that can truly make an impact on testosterone production.

  • Tribulus terrestris Fruit Powder Extract (Providing 33.75mg Total Saponins) – 500mg

    MFIT Supps Stress-66

    Stress-66 is a Stress & Cortisol Supplement Done the Modern Way: With KSM-66 Ashwagandha!

    Tribulus terrestris is a plant that thrives in warm, dry regions across the globe. With roots in both Ayurvedic and Traditional Chinese Medicine, the plant as anecdotally been used to increase libido and fertility.[11] Thanks to modern science, it appears those uses are warranted!

    Research has identified a strong aphrodisiac property within tribulus. One study from 2000 found that the plant had a pro-erectile effect in rabbits via increased nitric oxide production.[12] Another study from 2012 found even more interesting results – not only did sexual behavior increase in a dose-dependent manner, but so did serum testosterone.[13] While this boost in testosterone is encouraging in this singular study, further analysis has actually led scientists to conclude that tribulus actually does not increase testosterone.[14] Nonetheless, tribulus surely acts as a bit of a complement to other testosterone-boosting ingredients – libido tends to be directly associated with increased testosterone levels, after all!

    Include the trib for the feels

    Overall, tribulus is an ingredient that feels at home in a testosterone-focused supplement, despite not interacting with testosterone levels directly. If anything, it seems to complement some of the benefits of higher levels of testosterone!

  • L-Tyrosine – 500mg

    Yet another unorthodox inclusion in a testosterone booster, tyrosine is a conditionally-essential amino acid that operates as a cognitive powerhouse. It works in ways that differ from most other amino acids, being mainly concerned with neurotransmitters than muscle building!


    Long story short from our analysis — For the best effects from tyrosine, choose the regular L-Tyrosine version – which is exactly what MFIT SUPPS did!

    Research has shown that tyrosine is used by the body to manufacture a number of crucial neurotransmitters, such as dopamine (the “feel-good” neurotransmitter), adrenaline, and noradrenaline.[15] Thus, it makes sense that supplementing tyrosine can increase levels of these chemicals, inducing a raised state of cognition – a study from 2015 concluded as much, finding that subjects given tyrosine were much more capable of completing mental tasks in an efficient manner.[16] Pertaining to Peak Force in particular, however, is just how tyrosine is related to testosterone.

    While research remains ongoing regarding the relationship between tyrosine and testosterone, there are some early pieces of information that have been unveiled. One study found a significant link between hypogonadism and tyrosine kinase inhibition,[17] which lends credence to intaking tyrosine to maintain proper male functioning, despite this same study finding no effect on testosterone levels. Another study saw tyrosine alleviate symptoms of erectile dysfunction in mice, albeit in a small study.[18]

    The cognitive effects of tyrosine alone make it worth supplementing with the amino acid. However, when incorporating the potential effects on male health, its inclusion in Peak Force makes even more sense. This product is built to help men get their overall health firing on all cylinders. Considering how comprehensive and challenging that is, tyrosine is another, crucial piece of the puzzle!

  • LJ100Ⓡ [Eurycoma longifolia (root) Extract (22% Bioactive Eurypeptides, 40% Glycosaponins)] – 300mg

    Large dose alert!!


    LJ100 is the ONLY type of Longjack extract you want in a product. It’s the only clinically validated longjack extract demonstrated to work.

    Longjack, which is also known as both Eurycoma longifolia and Tongkat Ali, frequently makes appearances in testosterone-boosting supplements. This herb has been used for quite some time, mainly to increase virility and sexual drive.

    Tongkat Ali has displayed these anecdotal properties in research. A study from 2012 found that a 300mg daily dose of the herb increased libido by as much as 10.8% after 12 weeks.[19] Additional research has even found an effect on testosterone – research from 2014 saw a 400mg daily dose of Tongkat Ali induce increases in both total and free testosterone, as well as muscular contraction force in both men and women.[20]

    Most of Longjack’s powers are tied to its content of eurypeptides and glycosaponins, both of which LJ100Ⓡ, the form used here from HP Ingredients, is quite potent in. Overall, Longjack adds to both the testosterone-focused and non-testosterone interventions of this label!

    We often see LJ100 dosed at 100-200mg. This is a very welcome addition.

  • PrimaVieⓇ [purified Shilajit, providing 25.0mg Fulvic Acids] – 200mg

    PrimaVie Shilajit Logo

    PrimaVie Shilajit is an ultra-high quality extract of the ayurvedic remedy shown to boost testosterone production and muscle repair.

    Calling on the strength of yet another Ayurvedic “herb”, Peak Force makes excellent use of shilajit in this formula. Despite not holding the clout of some of its Ayurvedic cousins (such as ashwagandha and tribulus), shilajit has seen its popularity rise recently thanks to some promising research!

    Utilizing its high fulvic acid content, shilajit has been shown to maintain testosterone levels,[21] and may even be able to boost fertility.[21] While not exactly directly related to a testosterone supplement, research has also seen shilajit improve muscle pliability and recovery, as well![22]

    Peak Force uses PrimaVieⓇ, one of the industry’s most regarded shilajit formulated by NatreonTM. With 25mg of fulvic acids here, you can bet on this ingredient contributing to the overall testosterone-boosting, libio-enhancing effects of this label.

  • BioPerineⓇ [Standardized Black Pepper Extract to contain 95% Piperine (Piperum nigrum fruit)] – 12mg

    As MFIT likes to do with their health-focused labels, they’ve included a strong absorption-enhancing agent in Peak Force in the form of black pepper extract. Also known as piperine, this ingredient has been shown to increase the bioavailability of supplemented ingredients,[23] which means it helps the body more fully absorb ingredients it’s taken with. It doesn’t deliver any testosterone-related effects on its own, but it does elevate those from the other ingredients on the label!


    There’s a hot new brand on the scene, they’re run by a trusted manufacturer, and they’re fronted by none other than Guy Cisternino!

    Even more interestingly, the piperine inside can be a MAO inhibitor,[24,25] making the dopamine boost from L-Tyrosine last just a bit longer. And at 12mg, this is a rather large dose!

    Coming in the form of BioPerineⓇ from Sabinsa, Peak Force makes use of one of the most potent piperine extracts available. Its inclusion here is a sign of just how confident MFIT is in Peak Force and its overall effectiveness – they’re extremely proud of this label’s potential, and they want to make sure you get as much of it as possible!

Great formula, and regardless of your age, it’s going to be hard not to feel great from Peak Force.

Who can benefit from Peak Force?

It’s always important that we briefly discuss the purpose of testosterone boosters – when and why is it necessary?

As we alluded to at the beginning of this post, our bodies change significantly as we age, with perhaps the most altered aspect being the internal workings of our hormones. The rate at which the body produces hormones is significantly different in our earlier years – for example, younger men generally have more testosterone than they know what to do with! There are other benefits here, of course, but these levels of testosterone basically make building muscle, staying lean, and feeling strong much easier.


Fire yourself up with MFIT SUPPS Havoc, and bring yourself back down with CBSleep!

Aging men, in experiencing decreased testosterone production, tend to struggle with various challenges, such as decreased cognition, lethargy, lower libido, and loss of lean muscle and strength.[1] In addition, high levels of stress, something that is extremely easy to accrue in today’s fast-paced world, can be very damaging on testosterone production.[2] This dual-faceted attack on testosterone becomes very dangerous in men entering the middle-aged phase of their lives, as their bodies simply slow down from their early-20’s state of hormonal production.

That doesn’t mean that all hope is lost, however. Testosterone boosters can be effective, if introduced under the right circumstances and properly used. If your diet isn’t in check (eg stop eating all that soybean oil) or you’re not prioritizing sleep, don’t expect a testosterone booster to be a quick fix to low testosterone. If you’re still naturally producing the hormone at healthy levels, taking this type of supplement is hardly necessary. But, in aging men with low testerone levels, testosterone supplementation may be viable avenue to regaining a bit of health and vigor.[3]

Now that we’ve covered the dangers of low testosterone, as well as who the market for testosterone-boosting formulas should include, we can recommend Peak Force and its strong profile for the right people!


MFIT’s 2019 Rookie-of-the-Year Performance isn’t over yet!

MFIT Supps

MFIT SUPPS: Exactly what you need, when you need it.

As we age, our bodies simply cannot keep up with how it functioned in our youth. It becomes a bit harder to build and maintain muscle, to lose weight, to minimize stress (check out Stress-66 if that’s of concern to you!), and maintain hormonal production. In men specifically, testosterone production falling off is highly problematic – it decreases vigor, libido, power, and even confidence! Thus, it becomes incredibly useful to raise testosterone levels in these stages, as it helps one hold on to a bit of the libio and power they once had!

MFIT has introduced a tool for those looking to raise their testosterone levels to where they should be, despite outside factors – Peak Force. This incredibly potent, science-backed formula is an extremely well-rounded product, methodically designed to boost testosterone in hopes of elevating training efforts. With multiple clinically-tested, trademarked ingredients at effective dosages, Peak Force is just what we’ve come to expect from MFIT, and is a welcome addition to their product line!
