About the Brand

The manufacturer of Testosterin is a health and wellness company called NaturalSlim, headquartered in San Juan, Porto Rica, and with a U.S. office in Largo, Florida. Founded by the late Dr. Frank Suarez, the formula produces natural supplements to promote weight loss and offer other health benefits.

How Does Testosterin Work?

The Testosterin formula claims to increase levels of testosterone in the body, boosting sexual libido and energy, building muscle mass and strength, and promoting fat and weight loss.

While supplementation is not the same as testosterone therapy, a review published in Current Opinion in Endocrinology, Diabetes, and Obesity by Abdulmaged M. Traish discussed recent findings on the weight loss benefits of increased T levels:

Long-term testosterone therapy in men with testosterone deficiency produces significant and sustained weight loss, marked reduction in waist circumference and BMI, and improvement in body composition. Further, testosterone therapy ameliorates components of the metabolic syndrome [1].

In addition, there is some evidence to support the link between libido and testosterone levels, as we explained in our review of Eroboost. An epidemiological study published in The Journal of Clinical Endocrinology and Metabolism by Thomas G. Travison, et al found that sexual libido and testosterone levels are strongly linked at the population level [2].

Some of the ingredients in Testosterin may boost levels of nitric oxide, enhancing body-wide blood flow and vasodilation. The additional circulation to the penis may promote harder, longer-lasting erections.

A study of diabetic rats published in the American Journal of Physiology by Hong Zheng, et al concluded that a lack of nitric oxide may trigger erectile dysfunction [3].

The Testosterin formula also has antioxidants that eliminate harmful free radicals in the system and lower levels of oxidative stress. This helps lower inflammation, promote healing and repair, and strengthen the immune system.

Testosterin Ingredients – Are they Safe & Effective?

Some of the primary active Testosterin include:


This is a patented blend of the fenugreek plant, which may increase levels of testosterone in the body to heighten sexual arousal and stamina, boost energy, promote weight loss, and build muscles. In addition, fenugreek may help balance blood sugar levels, curb hunger, and improve digestion.

A 12-week study of healthy aging males with androgen deficiency published in The Aging Male by Amanda Rao, et al concluded that supplementation with Testofen® helped increase T levels, improve sexual function, and reduce the symptoms of androgen deficiency [4].

Tribulus Terrestris

According to some evidence this plant may have testosterone-boosting properties, as we said in our review of Eroboost. Some studies show that it can boost sexual libido, energy, and function, however, there are mixed results on its ability to build the muscles.

A 5-week study of rugby players published in The Journal of Strength and Conditioning Research by Shane Rogerson, et al concluded that supplementation with Tribulus Terrestris did not produce significant gains in muscle mass or strength [5].

Pine Bark

This extract is rich in antioxidants and bioflavonoids that support immune function and may improve body-wide circulation, which could promote harder erections. Research shows that it may boost testosterone and alleviate erectile dysfunction, especially when combined with l-arginine.

A 3-month study of men with organic erectile dysfunction published in the Journal of Sex and Marital Therapy by R Stanislavov and V Nikolova concluded that treatment with l-arginine and pine bark significantly improved erectile function [6].

Verdict: There is some evidentiary support for the testosterone-boosting, sexual health, and weight loss benefits of the primary active ingredients in Testosterin. However, because we don’t know the exact dosages of the ingredients in this supplement, we can’t come to a conclusion about its potency.

Testosterin Review – FAQs

Q: How Do You Take Testosterin?

A: The recommended daily dosage is 6 capsules in total. Take the first 3 before breakfast in the morning, and the second 3 after your lunch. Do not exceed the maximum daily dosage in 24 hours unless specifically directed by a physician.

Q: What Sets It Apart From the Competition?

A: The ingredients in Testosterin are typical of many other competing brands. It includes the testosterone booster Testofen®, but this is the fenugreek plant, and some other formulas also contain it. The price is relatively reasonable for the market, which sets it apart from some of the more costly brands.

Q: What is the Return Policy?

A: The official company website has no return policy or guarantee listed for Testosterin. You can buy it from other retailers like Amazon and Walmart but check their policies carefully before buying as not all companies refund perishable items.

Q: Is Testosterin Worth It?

A: Testosterin contains a blend of ingredients with some research support for its male sexual function and weight loss benefits, and the cost is fairly reasonable for the market. However, they do not provide individual ingredient dosages for the proprietary blend, so it is difficult to assess its true potency. It may be worth it, but there are also more potent brands on the market for a similar cost.

Q: Where to Buy Testosterin?

A: Testosterin is for sale on the official product website for $59 per bottle, and they pay the shipping costs. In addition, the supplement is also for sale from other online retailers like Walmart and Amazon, and the price varies.

What Do the Testosterin Reviews Say?

In our evaluation of existing male sexual enhancement supplements, we think that Testosterin is a high-quality but somewhat average product. The formula is backed by science and may offer weight loss and sexual health benefits to some men, but there are competing brands with richer blends and added ingredients.

While the cost of Testosterin is reasonable for the market, the fact that there is no return policy or guarantee is a real disadvantage. While we rate the supplement 4.85 out of 5 stars, on the whole, customer reviewers are higher.

On the official website, 70 customers gave Testosterin 4.9 stars, and 686 Amazon users rated the supplement 4.4 stars. The feedback varies, with some very happy customers and others who did not get the benefits they expected.

One of the best 5-star reviews on the official site is from Chris, who says he is happy with the physical and sexual benefits of the supplement:

I started going to the gym recently. I’ve been going for 5 months now. I started taking Testosterin for the past month and a half and I’ve noticed a big increase in strength and energy. I’ve also started losing body fat and increased muscle mass. Definitely recommend, also the girlfriend is very happy.

One of the most critical comments on Amazon comes from Osvaldo Fombellida, who says he got no benefits from Testosterin:

I didn’t see any improvement in me.

Verdict: Many customers on the official website and Amazon claim Testosterin works well to improve sexual function, but some say it offers no results.

Testosterin Review – Conclusion

In the final evaluation, we give Testosterin an average rating of 4.85 out of 5 stars. The formula contains some potent ingredients backed by research, so it may boost testosterone levels, enhance sexual libido and function, build muscles, and promote weight loss. However, without individual ingredient dosages, we can’t assess its true efficacy.

On the whole, the Testosterin reviews on the official website and independent sites like Amazon are quite positive. Some men say the supplement helped both their sexual function and athletic performance, but other results reported few effects.

Testosterin is an all-natural formula free of toxic additives and should have no serious side effects. If you do experience unpleasant symptoms, stop taking the supplement immediately. Before taking the supplement, get medical approval from a physician, especially if you have a health condition or take medication.

One must choose a supplement that belongs to a reputable company, contains scientifically tested ingredients, offers several benefits, comes with an affordable price as well as capable of providing fast and effective results.
