MuscleTech PEAK SX-7 Pre-workout And Testosterone Booster Review // Can It Boost Energy And Increase Testosterone Levels?

First Look:

This falls under the SX-7 banner from MuscleTech and we have already reviewed 2 other products from this line. Unfortunately, MuscleTech products so far have never really lived up to the hype. They all look great; of a good quality, well thought out, eye catching packaging and a strong brand albeit this one does look to be the runt of the litter.

Take a look at our Top 3 boosters for something effective.



Adenosine-5’-triphosphate (Peak ATP) – A dose of 400 mg for 15 days tended to reduce muscle fatigue and improved a participant’s ability to maintain a higher force output at the end of an exhaustive exercise bout.

Longjack (Eurycoma Longifolia, TongKat Ali) – Is a pro-fertility agent and aphrodisiac that appears to have a large body of evidence supporting this role and some evidence suggesting it may be an anti-estrogen and pro-erectile agent. Although there’s some research to suggest it may increase testosterone levels in animals and humans it is pretty lackluster which doesn’t bode too well.

For our in-depth ingredients guide checkout:

– Our best & worst testosterone booster ingredients –


2 pills per day; we prefer have 4 pills spread across the day to evenly spread the nutrients out and prevent massive peaks and troughs. 4 pills are the doses of our benchmark products. 600mg is the daily dose found here with this product and that is pretty shocking.


Okay, so the Peak ATP is dosed correctly which will help assist with releiving the symptoms of muscle fatigue as well as help increase your pwer otput – this could be great for sports such as football, rugby and tennis or other racket sports.

In terms of increasing testosterone levels…well, this doesn’t really look too effective at all, in fact it really isn’t. Longjack is always found in shitty ‘testosterone boosters’ which do not actually boost anything.


This is simply dosed really very low and has such a lack of supporting ingredients that it is hard to fathom. I really wish it had at least Vitamin D3 and D-Aspartic Acid to give it a kick.

The dosing recommendation is not optimal at all, we should be having at least 4 pills spread out across the day.

It is also $69.99 – that’s a lot of money for very few ingredients.


We’re not having much luck with any of the products from MuscleTech, regardless of how they package them up they all seem to be full of ingredients that may well be talked about a lot online but they just do not have the scientific backing to provide any firm basis behind the claims.

Therefore, as a result we have another product that promises much, has lots of show with its flashy labeling and not a lot of go.

Not only that, there’s a real lack of overall ingredients on a daily basis, not to mention any that would be useful to stimulate testosterone levels which leaves this lagging substantially behind the market leaders.

While it has 1 useful ingredient that is so rarely found in many products, it does not do enough to tempt me in to buying it, not when there are so many that are more complete and more importantly, effective.

It is about time MuscleTech stopped flooding the with shit and brought the effective ingredients found in their umpteen products to make 1, effective and worthwhile supplement.

As such, this will help boost energy levels, however, testosterone will have seen better days…

Take a look at what works to maximize your workouts at a reasonable price and safely.
