Now TESTOJACK 100 Testosterone Booster Review

Now TESTOJACK 100 Testosterone Booster Review


First Look:

Fitting in with the corporate ‘grille’ of NOW’s other products such as the ZMA and Tribulus this looks from an initial glance to be a product that would probably combined the 2 for convenience and a cost saving. It doesn’t particularly scream ‘testosterone’ at you and it all looks rather dated, like something that is at the back of a shelf in a health food store. I would look straight past this.

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



Tribulus – Once marveled, now known to have no effect on testosterone levels, by now supplement manufacturers should really let go.  Avoid like a medieval plague if you are looking for muscular gainz.

Zinc – An aphrodisiac and Testosterone Booster, but it will only raise testosterone levels if the user is deficient in zinc. Zinc is also very important for the functioning of the enzyme, hormone, and immune systems.In very high doses, zinc can act as an aromatase inhibitor and reduce estrogen levels. It is also a potent antioxidant and can provide benefits for prostate issues.

Vitamin B6 – Vitamin B6 helps testosterone levels by stimulating androgen (a steroid hormone that acts as a precursor for testosterone) receptors in your body, making your testes produce testosterone.

Tongkat Ali – Eurycoma (LongJack) 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. However, there is a lack of evidence for testosterone boosting in humans, although some very limited evidence in animals.

Eleutherococcus Senticosus (Siberian Ginseng) – Whilst there is evidence that this can actually help treat herpes and reduce the severity of cold and flu, there is very little solid evidence to reliably suggest this helps increase testosterone or increase strength.

Magnesium – Research into magnesium supplementation also increased testosterone production in men.

ZMA – Strangely this is already present with B6, Zinc and Magnesium…so just a double dose it seems.

For our in-depth ingredients guide checkout:

– Our best & worst testosterone booster ingredients –


There is a 2 pills per day recommended dose. We prefer 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. A daily serving is 1571.5mg.


There’s 6 ingredients; 3 work, 3 do not. However, not only that, there is a strange 7th ingredient which is a duplicate of the 3 that are effective at stimulating testosterone. Therefore we effectively have a double dose of B6, Zinc and Magnesium which is great, I just do not understand why it was packaged up separately.

However, there is nothing like D-Aspartic Acid, B12, K2 or D3 present. So it is effective…within reason.


The inclusion of tribulus, tongkat ali and Siberian ginseng are all deemed useless in studies. Therefore, what we have here is a highly dosed ZMA product, pure and simple and I do not think that is worth $42.99, not when there are full blown testosterone boosting products that are effective and do not cost much more.

It is worth reiterating that in our top 3 rated testosterone boosters they have around 8 solid ingredients which all have proof backing their usefulness and it is the same with fat burner’s too.


It does not have enough ingredients nor content to make this as effective as a good testosterone booster, a ZMA is a bit of a half way house and doesn’t really fulfill the testosterone boosting prophecy. NOW already have a ZMA in their line up, I would much prefer to see the ZMA with D-Aspartic Acid and D3 if anything was to be added.
