We will look into who Phi naturals are and what their reputation is like as a supplement company.
We will take a look at their claims about TestPlus and whether those claims are backed up by science, before we look into their ingredients list.
Finally, we will look at what their customers are saying before finally giving you our verdict on the effectiveness of TestPlus.
Quick Review: As a testosterone booster TestPlus isn’t going to do much.
In fact it’s more than likely a waste of your money.
The ingredients just don’t back up the claims and there are too many negative reviews.
My advice is to avoid this one and try something that is more proven to work.
Phi Naturals Company Review
Phi Naturals is a supplement company created by two doctors (Dr Rick Argall and Dr France Carpentier) in 2012.
Their first supplement was Collagen Complete but they have now branched out to sell a number of different products.
As a company they have a slightly dodgy reputation, the website Fakespot.com has reviewed them as a C when it comes to trustworthiness.
This is based on numerous fake reviews of their products on Amazon.
Out of 2,337 reviews 20% of them are marked as unreliable .
Now 20% is not a high percentage, however that means that 400+ reviews are potentially fake.
Not a great sign in a supplement company, but that doesn’t mean their product is bad.
It’s time to take a closer look at TestPlus.
On their Amazon page, Phi Naturals have a list of 15 benefits of taking TestPlus.
A lot of these benefits are rubbish though. For example; benefit #4 is “made in USA” and benefit #5 is “60 capsules”.
The worst “benefit” though is benefit #8 which is “herbs are combined in this one of a kind formula”, do you mean like every supplement ever?
The main benefits mentioned are that TestPlus enhances energy levels, increases muscle size and strength, and improves endurance.
They also mention improved recovery and improved libido.
These benefits are all fairly standard, and there aren’t any out of the ordinary promises.
TestPlus Ingredient Review
There are five ingredients listed in the TestPlus ingredients section, and they have given correct dosages for each.
This is always a good sign, as it indicates transparency by the company.
No under-dosed ingredients just added in to boost the ingredients list, and no nasty surprises.
The five ingredients are:
- Fenugreek (250mg)
- Indonesian Tongkat Ali extract (12.5mg)
- Tribulus Terrestris (100mg)
- Cordyceps Sinesis (100mg)
- Siberian Ginseng Root (100mg)
We will briefly take a look at each ingredient and the dosage before delivering our verdict on the ingredients list as a whole.
- Fenugreek (250mg): There does seem to be a small amount of evidence that Fenugreek can increase testosterone , but most studies have found no effect . It does appear to increase libido though. Recommended dosages of fenugreek extract are around 500-600mg and TestPlus only contains 250mg per capsule, but if you take 2 capsules at a time (as they recommend) you’re getting exactly the right amount of fenugreek to see results.
- Indonesian Tongkat Ali (12.5mg): Also known as Eurycoma Longifolia, Tongkat Ali does NOT increase testosterone production. But it can reduce cortisol levels in the very stressed, and it also improves libido. Phi Naturals boasts that their product is 100:1 which is the ideal form, however the recommended dosage is 200-300mg  and this supplement only contains 12.5mg (25mg if you take two capsules).
- Tribulus Terrestris (100mg): It feels like every testosterone boosting supplement in the world has this ingredient, even though it has been shown time and time again to have no effect on testosterone production! Like the other ingredients it can help with sex drive and erections though, so at least it has some benefits. The dosage should be 200mg so provided you take both capsules you’ll be hitting the rda.
- Cordyceps Sinesis (100mg): A mushroom used in Chinese medicine, there is no evidence that it has any effect on testosterone in humans. Some studies indicate an increase in testosterone in mice, but there just isn’t enough evidence to say either way. It also appears to increase Estradiol in mice so perhaps not the best idea for a testosterone booster.
- Siberian Ginseng Root (100mg) Siberian Ginseng has no effect on testosterone, but does appear to affect athletic performance. Some studies have found that it increases endurance while other studies have found no significant effect. It is possible that the addition of Siberian Ginseng could lead to increases in endurance and energy levels (it may reduce chronic fatigue symptoms).
There is a chance that TestPlus can increase testosterone, but based on the evidence available it seems more likely that TestPlus will have no effect.
It will definitely improve your libido, and may help with erections.
There is also a chance that it could improve your endurance and athletic performance.
But as a straight up testosterone booster? It’s just not that impressive.
The reviews are fairly standard for a natural testosterone booster.
Most people say that the supplements have improved their sex drive, some say they work, while others say they are a waste of money.
One reviewer mentioned an improvement in endurance (which could potentially be attributable to the Siberian Ginseng Root), and another one mentioned that their sleep quality had improved.
As with all testosterone boosters though, you should take these reviews with a pinch of salt.
Unless you have had your testosterone measured before and after taking a testosterone booster it is almost impossible to know if they have worked or not.
Increased libido is often seen as a good sign but as we have already established, a number of supplement ingredients can increase your libido without affecting testosterone production.
TestPlus Bottome Line
TestPlus is not a great testosterone booster, but it does have some redeeming qualities.
The increased libido and improved erections are a nice bonus, and the improved endurance (if Siberian Ginseng does increase endurance) will help you train better in the gym.
The company itself appears to be legit, though the potentially fake reviews mentioned by Fakespot.com are a little alarming.
On the whole we’re going to say avoid this supplement.
There are better testosterone boosters out there.
