Just like a good story, there are two sides to every serious T boosting effort. It’s all about getting testosterone up, but also keeping the female hormone, estrogen down.

The good folks at Jacked Factory clearly understand this. We recently reviewed their ANDROSURGE Estrogen Blocker, now it’s the turn of testosterone powerhouse PRIMASURGE.


That’s the main reason for this review really. To find out if splitting the effort between two supplements means better results for you, or better profits for them.

PRIMASURGE promises everything you might expect from a test booster:

  • Naturally increase testosterone
  • Improved strength & muscle mass
  • Boost ATP Levels

It also at least delivers on something you can’t always guarantee -> there are no proprietary blends. That means a full list of ingredients used and their dosages.

It’s your body, it’s your money, it’s your right to have all the facts. Well done Jacked Factory for not obscuring their formula.

How Does It Work?

At a Glance

  • Eurycoma Longfolia to stimulate libido
  • Ashwagandha to reduce stress and boost T
  • Safed Musli for libido and erection strength
  • Primavie® Shilajit and Boron Citrate for test boosting

As always with Jacked Factory, they go for quality over quantity. We’ll look at the ingredients more closely later in the review, first the scores …

The Scores


We admire any supplement that’s proud to show off it’s ingredients in full and not hide them in a blend. They also don’t try and dazzle users with a massive list of under-dosed ingredients – the formula is laser focused and isolates specific tasks for specific natural ingredients.

Whilst there are studies to support the inclusion of both Shilajit and Boron, we have marked the formula down on the basis that we’d have liked more direct T boosting ingredients to compliment the energy and libido enhancers. That said, you can’t complain too much at under $30 a bottle.


If you look at the overall market for test boosting supplements, you’ll quickly realize that anything in the $30 bracket is at the bargain basement end.

Normally you pay for what you get, but with Primasurge you are getting a good product at an excellent price. It’s not perfect, but it is excellent value when you look at the cost. It’s also worth noting that further discounts are available if you sign up to the Jacked Factory mailing list.


Let’s start with the good news for a change. PRIMASURGE is manufactured in the U.S in cGMP approved premises. Not only that but as we mentioned (and will keep mentioning because it’s so damn important) there are no proprietary blends. That means all the info is there on the label for anyone to see.

Jacked Factory have a good reputation, you’ll struggle to find negativity about them online and they have a ‘100% Hassle-Free Money-Back Guarantee’ money back guarantee. All these things inspire trust and we’re left with no alternative but to award them full marks in this category.


Jacked Factory products tend to suffer in this department. The reviews for this product are very positive, hence the positive score.

However we shun the ‘Great Product!’ style one liners and much prefer the type of detailed user stories that give us real insight into the product and the effects it has on the users. Before and after photos, videos – this is the kind of testimony that gets 10/10 on this site.


Jacked Factory have a modest range of supplements mostly centered around boosting T and burning fat. A lot of the info on their website centers around mission the statement, which is nice but a little more background would’ve been better.

That said the company are GMP certified and they do offer a money back guarantee if you buy directly from the official site.

How Do I Take It?

Users take 1 capsule 3 times a day 20 minutes before meals.

This is a strong serving schedule. By topping up active ingredients at regular points throughout the day, any advantages this booster has will not begin to wear off later on.

Any PRIMASURGE Side Effects?

One of the advantages of no proprietary blends is it’s easier to spot potential problems with side effects. In this case we can’t see there being much of a worry, outside of individual allergies.

Where Can I Get It?

The best place to buy PRIMASURGE is Jacked Factory’s official website.

Ingredients – In Detail

Safed Musli

Safed Musli Extract

Aliases : Chlorophytum Borivilianum

The first of our traditional Ayurvedic herbs with a strong anecdotal reputation for aphrodisiac and erectile strength qualities. Indeed one study (admittedly on rats rather than humans) demonstrated the latter quality to be true, and only slightly less effective than a certain popular erectile dysfunction drug beginning with the letter V.

[Editor: I’m not using it’s full name as Google has a habit of thinking your site has been hacked when it sees it mentioned.]

Has also been shown to demonstrate anti-stress properties, anti-inflammation, help with sleep and stimulate androgen activity. The problem is that despite being used traditionally for centuries, there is just not enough human clinical studies to work through. Although from a safety point of view we are reassured by the fact it has been used for centuries – the people on the Indian subcontinent using it would presukably have stopped quite some time ago had there been adverse effects.




Ashwagandha is a really useful adaptogen, meaning it aids the body adapt to stress. This can either be physical, as in allowing you to exercise for longer, or mental working to relieve stress.

It is shown to reduce cortisol, the stress hormone, at doses of around 250-300mg. We’ve got 250mg here, so that’s a real plus.


Shalajit Extract

PrimaVie® Shalajit Extract

PrimaVie® is a high quality, purified branded version of this traditional Ayurvedic medicine. A natural substance cultured in rock formations in high Himalayan mountains, the name in the local language Sanskrit literally translates to “Conqueror of mountains and destroyer of weakness”.

With an increase in follicle stimulating hormone being noted at just 200mg. T itself also rose significantly, but only in infertile men.

PRIMASURGE only has 125mg but the fact it’s a highly purified version of Shilajit makes it one of the stronger choices inthe formula.


Tongkat Ali / Eurycoma Longfolia

Eurycoma Longfolia

Otherwise known as Longjack or Tongkat Ali, this ingredient is one we class as a libido booster rather than a testosterone booster – if the product is aimed at the younger muscle building market.

Primasurge isn’t aimed at that market though, for us this is a low test booster for older guys. There is evidence of it being able to return test to normal levels for those who have clinically low test.




Boron is a really strong choice, which not enough boosters include in our opinion. Even a small amount can increase free T (the stuff not bound by SHBG) and other studies show it can also reduce estrogen.

Just 10mg was enough to see results and PRIMASURGE offers 5mg in each of its 2-3 servings. It’s got a proper shot at doing some good, and a great inclusion.


Anything Missing?

We’d have liked to see more direct test boosters that aren’t based on Ayurveda.


So, to answer our question posed in the title of the page: ‘Does PRIMASURGE deserves full block caps’.

I think on the balance the answer is a resounding YES. Yes, it could be improved. Yes, the testosterone boosting ingredients are all from Ayurvedic medicine. But Yes, that means that it has been used successfully for centuries. And ultimately, Yes it is priced super competitively.
