If you haven’t heard the whispers, there’s a new product that’s caught the eye of the supplement industry. Out of the more than 50 testosterone products we’ve reviewed over the last year, our product called Pronabolin, is our 2017 Editor’s Choice.
Pronabolin Secret Sauce, Revealed
First off, the formula is a blend of Testofen®, tribulus terrestris, fenugreek seed, coleus forskohlii, plus five other ingredients. We like that Pronabolin references multiple published studies to support marketing claims.
- Testofen®, one of Pronabolin’s main ingredients, is a fenugreek extract standardized to 50% Fenuside. The extract has been clinically tested on humans in several double-blind, placebo-controlled studies. Research shows it, “improves sexual function and increases serum testosterone in healthy, middle-aged and older men,” according to a study published in the journal Aging Male in 2016 . Additional research says, “Testofen demonstrated a significant positive effect on physiological benefits of libido.” . Studies also show benefits in fighting body fat with no loss in muscle strength, boosting libido and fighting the symptoms of androgen decreases that come with natural aging  .
- Tribulus terrestris, a part of Chinese and Ayurvedic medicine for centuries, has been used as an aphrodisiac and a treatment for impotence. Eastern European folk treatments claim tribulus terrestris works to improve muscle strength.
- Eurycoma longifolia, also referred to as longjack and tongkat ali, is a plant that originated in Malaysia and Indonesia. Like tribulus terrestris, eurycoma longifolia has a long history in folk medicine. Malaria was a serious problem in regions where the plant grew naturally. Local medicine men used the root bark and roots to treat the fever. The plant supplies phytochemicals, of which 4000 are known to be in existence.
- Fenugreek seed extracts and seeds are consumed in Europe, Asia and the Mediterranean as a food product. Locals claim it has a maple syrup-like flavor. In India, fenugreek is used as a vegetable in local cuisine. The oldest known use of fenugreek seeds dates to 4000 BC. Move forward thousands of years and ancient folk doctors suggested the extracts and seeds could be used to fight inflammation.
Pronabolin offers more than just support for the symptoms of low testosterone. There are other signs of aging that can occur over time.
- Horny goat weed, in addition to fighting erectile dysfunction, has been shown to support the production of new blood vessels and relax smooth muscles to increase blood flow.
These aren’t the only ingredients in Pronabolin. The formula also packs in coleus forskohlii, horny goat weed, milk thistle extract, alpha lipoic acid, digestive proteolytic blend and black pepper extract.
Did You Know This About Testosterone?
Testosterone levels affect more than libido, erectile function and muscle growth and maintenance. There are some issues an increase can fight that you may never have considered. Increasing testosterone levels can help:
- Improve cognitive function in aging men.
- Support bone growth.
- Fight the onset of metabolic syndrome.
- Improve mood and fight depression.
- Increase absorption of calcium.
It isn’t just about how you perform in the bedroom or gym, it’s about achieving a better quality of life. Boosting testosterone levels can fight the signs of aging in ways you may never have thought possible.
And The Final Verdict on Pronabolin
In addition to solid science, another reason why Pronabolin wins this year’s Editor’s Choice is the makers of the product have been in business for 7 years and have sold to over 200,000 customers.
As it turns out, unlike many other testosterone supplements, we found the main ingredient in Pronabolin helps healthy, aging men:
- Increase testosterone levels.
- Improve sexual function.
- Reduce age-related symptoms associated with androgen decrease.
- Heighten performance and boost muscle mass.

Readers deserve all the facts, so we dug deep into Pronabolin ingredients to give you just that.
Tribulus terrestris is a fruit grown in the Mediterranean. Another name for it is puncture vine, because of spikes all over the plant.
What is it Supposed to Do?
There are studies and reports that say tribulus terrestris can help with angina, circulatory issues, heart issues and erectile dysfunction.
Based on a study published in the Journal of Sex & Marital Therapy, “Results showed a statistically significant difference in the level of testosterone…Also, the study showed statistically significant correlation between testosterone (total and free) and IIEF-5 [erectile function test].” 
Another study in Clinical Medicine Insights: Women’s Heath says, “Our results strongly support the safety and effectiveness of T. terrestris extract in the treatment of female sexual dysfunction.” 
Eurycoma longifolia is an herb, also referred to as longjack or tongkat ali.
What is it Supposed to Do?
Some of the eurycoma longifolia benefits may include improved erectile function, increased testosterone levels and increased sexual desire.
The Journal of the International Society of Sports Nutrition says, “[Eurycoma longifolia] may be an effective approach to shielding the body from the detrimental effects of “modern” chronic stress, which may include general day-to-day stress, as well as the stress of dieting, sleep deprivation, and exercise training.” 
Another study, in Complementary Therapies in Medicine offers, “Based on current evidence, the herbal extract of Tongkat Ali may have clinical effect on erectile function.” 
Fenugreek Seed Extract
The first use of fenugreek extract spans back to 1500 B.C. The seeds of the plant are used.
What is it Supposed to Do?
There is a connection between fenugreek extract and improved athletic performance, decreased fat and improvements in cholesterol and blood glucose levels.
A study in the International Journal for Vitamin and Nutritional Research claims, “This study shows that fenugreek seeds can be used as an adjuvant in the control of type 2 diabetes mellitus.” 
The Journal of the Association of Physicians of India published a study that claimed, “Adjunct use of fenugreek seeds improves glycemic control and decreases insulin resistance in mild type-2 diabetic patients. There is also a favourable effect on hypertriglyceridemia.” 
Coleus forskohlii is a plant that contains a chemical called forskolin. This ingredient can be found in some testosterone boosters and other muscle-building supplements.
What is it Supposed to Do?
For thousands of years, coleus forskohlii has been used to treat conditions like chest pain and high blood pressure. There’s also a potential connection between the ingredient and weight-loss or weight management.
The Journal of the International Society of Sports Nutrition offers a study that says, “CF [coleus forskohlii] has the potential to positively influence the loss and management of overall body weight possibly as a means of maintaining weight after weight loss.” 
Studies into the ingredient are on-going. According to ClinicalTrials.gov, “Preliminary studies have shown that forskolin can increase fat metabolism thus reduce fat accumulation in both animals and humans. It has been suggested that forskolin may also suppress appetite thus reduce energy intake and results in weight loss.”

Pronabolin Side Effects:
Pronabolin is a natural testosterone booster that’s quite popular. We found amazing reviews and success stories, but we want to offer both sides of the story. When we searched for reports of side effects we literally found one – just one.
“I felt really sore during the cycle of Pronabolin. The soreness that someone gets when they first begin to work out. I am not sure if it was something with the supplement(s) pushing me harder or something else but it was almost refreshing to feel that again.” Miles
We read hundreds of Pronabolin reviews and muscle soreness, which can be attributed to working out harder, was the only negative. If you want to give this one a try, you can take advantage of a multiple-bottle discount and 120-day money-back guarantee.

Previous Pronabolin Review (Updated July 2, 2015):
Pronabolin: What You Should KnowPronabolin is a testosterone booster with tested ingredients that work to support testosterone production and help raise testosterone levels. Many testosterone boosters contain one or two of these tested ingredients, but Pronabolin packs together nine ingredients that work synergistically to help you fight the hands of time. The official website for Pronabolin is quite impressive. All of the ingredients are listed and a detailed description of each ingredient. If you are looking for a testosterone booster to promote weight loss and fight the symptoms of low testosterone that so many men suffer, Pronabolin is the right choice.
List of Ingredients in PronabolinTribulus terrestris, fenugreek seed extract, digestive proteolytic blend, coleus forskohlii, milk thistle, alpha lipoic acid, eurycoma longifolia extract, horny goat weed and black pepper extract.
Product FeaturesTribulus terrestris is a fruit shown to boost libido, help relieve infertility and boost athletic performance. Testing has shown a possible increase in sperm quality and production, improvement in erectile function and boost to libido in as little as 30 days.Fenugreek seed extract is also shown to help boost athletic performance, but there are also other benefits that could help promote weight loss. Endurance in the gym is critical to weight loss. If you find yourself tired before the completion of your workout, you are not getting the benefits you need to lose more weight. With fenugreek extract, your endurance is longer so you spend more time in the gym and burn more calories. Increased calorie burn leads to increased weight loss.Click here to learn more about this awesome advancement in the world of fitness.Digestive proteolytic blend has nothing to do with testosterone production, but it does have to do with how the ingredients in Pronabolin work in the body and overall weight loss. Many people suffer from sluggish digestive processes. The ingredients that make up the digestive proteolytic blend work to improve digestive performance so the ingredients are more readily absorbed. The nutrients in the foods you eat are more available to the body. With improved nutrient absorption the body works better and recovers better so you can work harder to lose weight.Coleus forskohlii is not an extract – it is a chemical. The primary use of coleus forskohlii in the past was for heart issues. Today you can use the supplement to fight obesity and improve erectile function. Studies into coleus forskohlii have reported decreased food intake with regular use. Eating less is one of the best ways to lose weight. An increase in T4 (thyroxine) is another welcome benefit for dieters. Thyroxine levels are parallel to metabolism. More T4 means faster metabolism.Milk thistle is another ingredient that is not directly connected with testosterone production, but it is associated with liver protection. Ingredients in Pronabolin are processed in the liver. Protecting the liver for long-term health is important to your health and well-being.Alpha lipoic acid works on the thyroid rather than testosterone levels. The acid blocks the process of metabolism of thyroxine or T4. With more T4 in your system your metabolism works overtime so you lose more weight. Increased thyroxine level is a natural way to increase weight loss without any harmful side effects. Think of T4 as a stimulant that does not cause side effects of stimulation.Eurycoma longifolia has been tested. When participants took the extract for a minimum of one month testosterone levels increased. Participants also reported fewer symptoms of low testosterone. Two of the more common symptoms of low testosterone are fat accumulation around the midsection and weight gain. Fighting these symptoms is the selling point for a product like Pronabolin. Counteract the symptoms and you feel better, live better and lose more weight.Horny goat weed is a libido booster that helps improve sexual performance. There are also reports that the weed can help improve memory and ease pain in your joints. Low testosterone is more common in older men. With age comes joint pain so you cannot spend the time in the gym or on the treadmill that you’d like. The horny goat weed in Pronabolin works to fight pain so you workout longer. Longer workouts lead to more calorie burn and weight loss.Black pepper extract is similar to the digestive proteolytic blend in the fact that it improves the absorption of other ingredients in the formula. No matter how strong the ingredients in Pronabolin are, if they are not absorbed effectively the supplement will not work as well as it could. Black pepper extract is derived from black pepper (the seasoning). You cannot consume enough black pepper to gain the benefits associated with the extract in Pronabolin, but adding more black pepper to your diet is a healthy option. Unlike so many other testosterone boosters, Pronabolin is not just made for older men. Ingredients in the formula can improve how you perform in the gym, even if you do not suffer from low testosterone.

ConclusionIn the world of testosterone support, Pronabolin is one of the best you will find. The ingredients are shown to work on more than just testosterone production, something other supplements forget. Taking Pronabolin for at least 30 days could result in increased weight loss, especially if weight gain is associated with low testosterone. You can even use Pronabolin if you are young and fit as many of the benefits affect athletic performance and endurance. The makers of Pronabolin are so confident in their product they’re offering every customer a 120-day money-back guarantee and multiple-bottle discounts.

Pronabolin Scientific Abstracts:
Fat-free mass and strength were elevated following 5 weeks of training with no between-group differences. There were also no between-group differences seen in the urinary testosterone/epitestosterone ratio. In conclusion, Tribulus terrestris did not create significant gains in lean muscle mass or strength within a 5 to 28 day time frame. In addition, Tribulus terrestris did not change urinary testosterone/epitestosterone ratio and would not test positive in athletes based on the World Anti-Doping Agency’s urinary testosterone/epitestosterone ratio of 4:1. 
In this double blind and randomized study, there were no noteworthy differences seen in macronutrient or caloric intake. Coleus Forskohlii showed a tendency toward mitigating gains in scanned mass (-0.2 Â± 1.3, 1.7 Â± 2.9 kg, p = 0.08) and body mass (-0.7 Â± 1.8, 1.0 Â± 2.5 kg, p = 0.10) with no substantial alterations in fat mass and fat free mass ((-0.2 Â± 0.7, 1.1 Â± 2.3 kg, p = 0.16, -0.1 Â± 1.3, 0.6 Â± 1.2 kg, p = 0.21, respectively). There were no significant changes in body fat (-0.2 Â± 1.0, 0.4 Â± 1.4%, p = 0.40). Participants taking Coleus Forskohlii showed a tendency to report less hunger (p = 0.02), fatigue (p = 0.07), and fullness (p = 0.04). There were no clinically important reactions noticed in blood lipids, metabolic markers, muscle and liver enzymes, white cells, red cells, heart rate, hormones, blood pressure, or mentions of side effects. It was concluded that Coleus Forskohlii did not seem to cause weight-loss, but could assist in mitigating weight gain in overweight female participants. There were no clinically significant side effects reported. 
Fenugreek Seed Extract
In this double-blind randomized placebo-controlled three-period cross-over trial, consumption of daily fat was substantially reduced by greater amounts of fenugreek seed extract [3.73 versus 4.51 MJ day(-1), -17.3% versus placebo, 95% confidence interval -1.51 to -0.05, n = 12, P = 0.038]. This decrease showed a tendency to reduce total energy intake (9.97 versus 11.29 MJ day (-1), -11.7% versus placebo, 95% confidence interval -2.91 to 0.26, n = 12, P = 0.094). No effects were found in the other nutrients. In conclusion, fenugreek seed extract reduced dietary fat consumption in human participants. When taking into consideration the traditional applications of this plant, this was a novel result. 
The effectiveness of Milk Thistle is not well-known or established in the scientific community. The published evidence at this time is clouded by subpar reporting and design. 
No evidence of carcinogenic activity was seen in this 2-year study within male and female rats given 12,500, 25,000, or 50,000 ppm. When female rats were given Milk Thistle, subjects experienced increased incidences of mixed cell and clear cell foci in the liver. Decreased body weight was seen in both male and female mice groups. There were reduced incidences of mammary gland neoplasms in the female rats and reduced incidences of hepatocellular neoplasms in male mice. 
Alpha Lipoic Acid
The beneficial effects are accomplished with low micromolar levels of Alpha Lipoic Acid. This indicates that some of its therapeutic properties reach past the strict definition of antioxidant. There are trials currently looking into whether said beneficial properties of Alpha Lipoic Acid make it a possible treatment for diabetes, but also an avenue to prevent vascular disease, inflammation and hypertension. 
Eurycoma Longifolia Extract
There were substantial improvements seen in the Tongkat Ali (Eurycoma Longifolia) group in Anger (-12%), Tension (-11%), and Confusion (-15%). There was great improvement in stress hormone profile (testosterone and salivary cortisol) due to Tongkat Ali, accompanied by increased testosterone status (+37%) and reduced cortisol exposure (-16%). It was concluded that stress hormone profile and specific mood state parameters were improved with daily supplementation of tongkat ali root extract. This gave credence to the idea that this ancient remedy could, in fact, be effective in treating modern chronic stress. This can include the general stress from day-to-day life, along with the stress of exercise, sleep deprivation and dieting. 
Horny Goat Weed
Low-dose ICA (Icariin/Horny Goat Weed) given to rats showed substantially greater area under the curve (AUC)/ mean arterial pressure (MAP) and intracavernous pressure (ICP)/MAP ratios in comparison to single dose ICA and control. Western blot and Immunohistochemistry showed greater positivity for neuronal nitric oxide synthase (nNOS) and calponin within penile tissues of rat subjects given ICA. 
Black Pepper Extract
Alklylamides IC50 (Inhibitory concentrations 50%) were within the 13-200 microg/ml range. Lipid peroxidation (LPO) was inhibited by 45-85% due to black pepper extract at200 microg/ml and the compounds within it at 25 microg/ml. In addition to this, cancer cell proliferation was inhibited by 3.5-86.8% and COX enzymes were inhibited by 31-80%. In conclusion, the results suggest that black pepper shows antioxidant, anti-inflammatory and anticancer activities.
