Vitruvian Natural Lab – Premium Herbs LongJack Coffee Testosterone Booster Review

First look

This is the first coffee based testosterone booster we have come across, albeit, not the first drink based testosterone booster we have reviewed, that honor goes to T-Male Liquid which came in a huge bottle that was reminiscent of an energy drink you see kids draining across the country.  Now, there is no reason to suggest a coffee with the right ingredients won’t work, and who doesn’t like a refreshing and stimulating drink throughout the day..?

Now I am quick to judge, usually before someone opens their mouth too, but it can lead us in to trouble, however, I cannot help but think this looks a bit naff, like something from a cheap roadside motel would offer in a schaet. But let’s see…




Find out which ingredients work and which don’t
Testosterone boosting ingredients

Now this is a bit difficult, because although we can see the ingredients, there’s no amounts listed, a bit like a super secret proprietary blend.

Maca Root – This Peruvian strain of ginseng is great for lifting libido and mood, however, when it comes to raising testosterone levels it has no effect at all. No significant influences on testosterone in any tested demographic I’m afraid.

Longjack Extract – Eurycoma (Tongkat Ali, 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.

Guarana – This is a stimulant and contains caffeine which works to stimulate the heart and muscles. There’s talk of it being used for mental clarity but actually little evidence to support these claims.


1 sachet per day. Normally we would say 4 doses per day to maximize the ingredients but these ingredients are pretty lackluster.


Now this is a novel way of taking (reportedly) a testosterone booster, however, not one of these ingredients is proven to stimulate testosterone production in your body. It claims to offer ‘real power’, and yes, the caffeine in the guarana and coffee may get your pupils dilated and your heart beat raised a bit, it may even help towards fat burning but there’s no testosterone trigger here.


Apart from the fact there are no testosterone boosting properties available here, there’s no mention of the amount of each ingredient listed. We don’t know if we are getting 1mg of Maca or even 1000mg (most likely the former). That worries me as this is nigh on $40 for 8 sachets, that equates to less than half a month’s worth for quite a lot of money or if you think about it, $5 for a freeze dried coffee, no one in their right mind would pay that and why would you pay it for the liberty of it including unproven ingredients?

So not only do we not know the amount of the ingredients listed, it is very poor value for money too.

My Premium Herbs LongJack Coffee Testosterone Booster Review Conclusion

This is no way  looking to be a real contender for our #1 spot, it has a proprietary blend and omits any excellent ingredients such as Vitamin D3, D-Aspartic Acid, B12, B6, Magnesium, Zinc, Fenugreek which all help towards testosterone production. There’s nothing present here that will help trigger testosterone production as we were told on the packet. It also represent horrendous value for money offered in the way of a feeble sachet of freeze dried coffee that will taste like shit.

It’s a flat (white?) no from us.
