How Does Testosterin Work?
The ingredients in Testosterin have some research support for their ability to boost levels of testosterone in men. This may boost sexual libido and stamina, increase energy, and build muscle mass and strength, as we explained in our review of Keskara. In addition, the added T levels could help promote fat-burning and weight loss.
A 60-month study of hypogonadal men published in The Journal of Urology by Dany-Jan Yassin, et al concluded that testosterone injections reduced obesity parameters.[1]
Lead researcher Dr. Dany-Jan Yasin explains the results:
We hypothesized that long-term testosterone improves metabolic syndrome and found that this intervention improved all three components of obesity, including waist circumference, weight, and body mass index; diabetes control; poor lipids profile; and blood pressure.[2]
The Testosterin formula has ingredients that enhance the synthesis of nitric oxide in the body, which improves circulation and vasodilation. This may support heart health, and the added flow of blood to the penis could promote harder erections.
A research review by Maria Rosaria Melis and Antonio Argiolas published in Biomolecules evaluated the benefits of nitric oxide in the central nervous system and its impact on sexual function.[3]

The ingredients are high in anti-inflammatory agents which could reduce swelling, speed up healing, and improve exercise recovery. In addition, it has antioxidants that lower oxidative stress levels by abolishing damaging free radicals. This can strengthen the immune system and promote healing and bodily repair.
What Are the Ingredients?
Some of the primary active Testosterin include:
L-Arginine – This key amino acid boosts the production of nitric oxide in the body to improve circulation, as we explained in our review of Boosted Pro. This sends added blood flow to the penis, which could promote harder, longer-lasting erections. In addition, l-arginine supports heart health and may balance blood pressure.
A systematic review and meta-analysis published in the Journal of Sexual Medicine by Hye Chang Rhim, et al concluded that supplementation with l-arginine could help relieve mild to moderate erectile dysfunction.[4]
Ginkgo Biloba – This tree extract also enhances blood flow in the body by increasing nitric oxide levels and may help alleviate erectile dysfunction. In addition, there’s some evidence that it may boost testosterone levels to heighten sexual libido, energy, muscle development, and weight loss.
A study of rats with erectile dysfunction due to nerve damage published in Urology by Yi-No Wu, et al concluded that ginkgo biloba supplementation helped repair nerve damage and restore sexual function.[5]
Testofen® – This is a proprietary form of the fenugreek plant, which has evidence showing its ability to heighten testosterone levels and improve sexual arousal. Fenugreek could also help promote weight loss, boost energy, and improve muscle mass and strength.
A 6-week study of healthy men published in Phytotherapy Research by Elizabeth Steels, et al concluded that supplementation with Testofen® increased libido and may help balance testosterone levels.[6]
Verdict: There is some research support indicating the potential testosterone-boosting benefits of the primary active Testosterin ingredients, and their ability to boost sexual libido and energy, promote harder erections, and encourage weight loss.

Testosterin contains an all-natural blend of ingredients that are safe and have no serious side effects, but some users may experience mild issues like nausea, headaches, or dizziness.

Testosterin Customer Reviews
On the whole, Testosterin is a quality all-natural supplement for men with research backing its sexual health and testosterone-boosting properties. However, as they don’t provide dosages for most of the ingredients, we have no way to assess the true potency of the formula. In addition, the fact that there is no guarantee or return policy is a distinct disadvantage.
The customer reviews vary, but on the whole, are quite positive. On the official website, 70 users give a total rating of 4.9 out of 5 stars. On Amazon, 686 customers rate the formula 4.4 stars.

One of the top 5-star comments on Amazon is from Olen Gutierrez, who says Testosterin works well when combined with a healthy lifestyle:
Try It Every Penny is Worth It: Amazing Product… But you need to change your lifestyle (healthy food and some exercise) … Excellent product, but you have to make lifestyle changes. Personally, I feel my body (muscle mass) is super different before and after, but with daily exercises.
One of the most critical 1-star comments comes from Natacha Guerra (Simon), who says her husband dislikes the taste and scent of the capsules:
Horrible Smell and Aftertaste: I bought this for my husband hoping it was good like other products from NaturalSlim, but this has a terrible smell and he had to stop taking them due to the terrible aftertaste it left in the mouth.
Verdict: On the whole, the customer reviews of Testosterin are fairly positive, although not all users got the expected benefits, and some disliked the flavor and scent of the supplement.
Where To Buy Testosterin?
You can purchase Testosterin on the official NaturalSlim website, and it’s also available from other retailers like Amazon and Walmart. The best deals are from the manufacturer directly. The price of one bottle is $59, and the company pays for the shipping.
What Sets It Apart from the Competition?
Testosterin contains Testofen®, a proprietary form of fenugreek that boosts testosterone levels not included in many other brands. Otherwise, the formula is typical of competing products, and some brands have more potent blends than Testosterin.
Final Verdict
In conclusion, we think Testosterin is a quality male sexual enhancement supplement that may help heighten libido and stamina, promote harder erections, boost energy, and encourage weight loss. However, as they do not provide ingredient dosages, we can’t guarantee its potency. The price of this supplement is reasonable for the market, but there is no guarantee or return policy.
On the whole, the reviews on the official website and independent sites like Amazon are fairly positive. While results vary and some users did not get the expected benefits, other men say the formula works very well to heighten sexual libido and performance, promote weight loss, and boost energy and stamina.
Testosterin is an all-natural supplement free of artificial additives or toxins, and the ingredient has no serious side effects. Some users may experience mild issues, and if you have unpleasant symptoms, you should stop taking the supplement immediately. Before taking Testosterin, make an appointment with your doctor to get medical approval.

Minor changes, moderate energy boost, awaiting full effects!
I’ve been using Testosterin for a couple of weeks. The changes are minor; I feel slightly more energetic, but it’s not making me stay long. It’s decent but not exceptional. I’m planning to finish the bottle to see if the effects improve, but it’s just okay so far.
