Test Booster is a natural testosterone supplement from company True Grit. It’s an uncomplicated name for an uncomplicated product. True Grit Test Booster sets out to achieve three clear goals and bring us the benefits of higher T.

The first, as you might expect, is to help stimulate our body’s own T, the second is to keep the body’s level of the female hormone, estrogen, down and the third is to limit the amount of cortisol in our system.


Estrogen is at the opposite end of the hormonal balance to testosterone. When one is up the other is down and vice versa. Cortisol, the stress hormone made while we’re under pressure, blocks T production.

Effectively the second and third aims are to clear the way for effective execution of the first.

True Grit shoot from the hip from an formula point of view. They steer clear of proprietary blends, showing us all components in name and amount. Let’s not waste any time tracking down this gang of ingredients, we’ll find out if they will indeed give you ‘grit’.

We fully analyse the ingredients and the dosages in True Grit Test Booster later in the article. First though … the scores

The Scores

True Grit

There are a few really solid choices here which guarantee a purchase of True Grit Test Boost won’t be a waste. There’s good zinc and boron content and the fenugreek is well judged.

However there are a few questions to answer both about what made it in and what’s missed. Safed musli, Gucos Yesiculosus and Smallanthus Sonchifolius need to do more to convince us and their place could’ve been given to better boosters.


The $30 region for this is not bad. Although it’s possibly a shade overpriced given how finely balanced its pros and cons are. However you don’t have to look far to find other brands which you’d pay a lot more for and receive a lot less.


There are no reviews on the True Grit website, meaning we’re left with customer reviews on retail sites and since this is a Bodybuiding.com exclusive, that’s the only place we’ll get them. As always these vary in detail and therefore usefulness but we’re stuck with them.

Reviews are generally positive although there is a smattering of negative reviews citing little or no results at all.


We couldn’t find any serious issues with this product. True Grit deserves credit for including all components and their respective volumes on the label.


True Grit recently picked up Best New Brand at the 2015 Supplement Awards and disagreements on ingredients aside, it’s easy to see why.

Test Booster was released as part of a set of 6 supplements including Pre, Post, Thermo, Multi and Protein, all of which are selling well. Their website is thorough and informative with exercise and diet advice alongside the supplement pitches. So no complaints. They also deserve a +1 for having a pun as their corporate domain name.

How Do I Take Test Booster?

It is recommended that you take 2 servings consisting of 2 capsules in the morning and at night. 4 capsules overall is a good number as far as convenience is concerned, but 1 serving to carry you through the whole day is asking a lot of any supplement.

True Grit Side Effects?

We wouldn’t expect any side effects from this product based on these ingredients.

Where Can I Get True Grit Test Booster?

True Grit Test Boost currently retails exclusively from bodybuilding.com where you can pick up a month’s supply of 60 capsules for $29.99. It’s not available in the U.K or Europe at present.

True Grit Testosterone Booster Ingredients – In Detail



Zinc is amongst the best minerals for helping your testosterone. A healthy supply of zinc means optimum creation of luteinizing hormone, which is chiefly responsible how much testosterone is created in the testes. The link between insufficient zinc intake and lower T is firmly established. Too much of it can be counterproductive, but with two servings of 15mg a day and our tolerance around 40mg, there should be no such worries here.



Fenugreek is still widely in use as an integral part of alternative remedies and in Asian cuisines. It has a great reputation as an effective libido booster, but over and above that its status 4-hydroxyisoleucine compound means it is able to regulate blood sugars. This helps to balance insulin, which if skewed negatively will affect testosterone. 300g is a great amount too, certainly enough to do a job.


Broccoli (as Brassica oleracea)

This may seem a bit of a weird one at first glance, but broccoli is here for its Diindolylmethane content. In a pilot study in 2011, DIM as it is known, demonstrated significant anti-estrogen abilities, which potentially makes it a good choice for True Grit Test Booster, given its aims. 250mg seems a strong amount, though if we had one complaint it’s that the amount of DIM within the broccoli is undisclosed, and therefore may not be quite the force it can be.



This is a herb used in Ayurvedic medicine for a variety of health complaints, but obviously it’s here for its T. A 2010 study did find that a whopping 5g of this ingredient was able to restore test levels in unfertile men, if not quite raise them beyond normal range. A follow up study in 2011 found that Ashwagandha’s ability to support testosterone was more evident in stressed men. Test Booster promised to help deal with cortisol so this might be the tie-in here, but 125mg, even over 2 servings, is a long way short of the physical amounts which demonstrated effective test boosting.

Shilajit Extract

By no means proven, but shows promise. A 2010 study on infertile men found Shilajit Extract was able to increase T, in infertile guys. No research has been done on healthy guys though so it’s perhaps a little early to be picking it for the team.


Boron Citrate

100mg of this with 5% standard boron so you are getting 5% of the mineral. Boron can not only increase T- a study using a similar dosage present here by as much as 28% – but it can also effectively reduce Sex Hormone Binding Globulin. SHGB is a protein which attaches itself to testosterone rendering it unusable. Test not tied up like this is referred to as ‘free testosterone’. Boron is one of the best natural means of increasing this snd therefore a great choice.

Safed Musli

An Indian herb which shows promise in clinical trials. While it’s unclear whether or not it affects T levels, it does seem to help some of the symptoms associated with low T. For example, safed musli is known libido booster, reflected in a 2011 study that reported a marked improvement in erection strength. Lab rats that were given this have seen the weight of their prostate rise, something linked to higher T, but until the research is better and subjects are less hairy, we’re sitting on the fence.

Gucos Yesiculosus

A 2004 study by the BMC Complementary and Alternative Medicine suggested that Gucos Yesiculosus may decrease 17b-estradiol levels, thanks to a bioactive compound called fucophorethols, thought to contain anti-estrogen properties. However there are no human studies as yet to support this.


Smallanthus Sonchifolius

AKA Yacon. There is some early evidence this may be of use to our T. In a study conducted on mice over 6 weeks, 200mg of Yacon was found to reduce the breakdown of T, keeping more of it in the system for longer. So promising but needs more human studies to get us properly excited.


True Grit Test Booster is a finely balanced supplement. There are a few well dosed and effective ingredients but a few that the jury is still out on, and feedback reflects that. So while it’s not the Sheriff of T town, at around $30, it might make a decent deputy.
