Advanced Test-O-Boost Review
Niwali’s Advanced Test-O-Booster was designed to improve workout endurance and intensity.
What’s more, the bold proclamation on its website is to “Get more attention from women attracted to your lean, hard, sexy body.”
This promise grabbed my attention, but is Advanced Test O Booster effective enough to hold it?
Advanced Test-O-Boost Advantages
Advanced Test-O-Boost provides is a transparent ingredient label, with each ingredient amount prominently displayed next to the name. This makes it easier to compare the amounts with their respective dosage recommendations.
What’s more, it contains multiple ingredients commonly used to improve male enhancement.
L-Arginine (300 mg). Arginine is commonly found in male enhancement supplements for its ability to convert into nitric oxide. Nitric oxide plays a fundamental role in getting and maintaining erections by prolonging the second messenger cGMP.
Zinc (50 mg). In addition to supporting a healthy immune system, zinc plays an integral role in enzyme production and testosterone maintenance.
Advanced Test-O-Boost includes more zinc than the tolerable upper intake level (40mg). Prolonged zinc intake above the upper limit increases adverse health risks. 
Tongkat Ali (Eurycoma Longifolia)(50 mg.) One study published in the Journal of the International Society of Sports Nutrition showed 200mg/d tongkat ali improves psychological mood state in regards to stressors such as aging, dieting, and exercise. 
Advanced Test-O-Boost Disadvantages
Despite featuring some effective ingredients, the dosages fall below the recommended amount to improve male enhancement.
Arginine, for example, is recommended by experts at 5 g arginine daily for erectile dysfunction. 
Furthermore there’s only 50mg tongkat ali, which is well below the 200mg used in the study.
The price is also a significant disadvantage. While there is a money back guarantee, the initial $67.00 for a month supply is steep.
What Reviewers Are Saying About Advanced Test-O-Boost
BestEnhancementReviews.com gives it 3.5 out of 5 stars and suggests Advanced Test-O-Boost is best for men who “…want to feel a little better, do little better at the gym and have more sex.”
Rob Miller at SupplementCritque.com gives a 3 out of 5 star rating. He recommends taking Advanced Test-O-Boost for overall health, but also suggests looking for an inexpensive alternative with similar ingredients.
Is Advanced Test-O-Boost For You?
Ultimately, Advanced Test-O-Boost does have a money back guarantee which puts the mind to ease about the steep cost. However, the ingredients fall below recommended dosages, and I was unable to find for a reliable source for customer reviews.
The best course is to look for an alternative product with similar ingredients and better price.
