Rising concerns about libido loss and low testosterone have more men looking at natural male enhancement supplements like Advanced Test-O-Boost for an answer.

Among the benefits offered by Advanced Test-O-Boost are more “confidence, mental and physical energy, and competitive drive.”

But does Advanced Test-O-Boost qualify as one of the best testosterone supplements? Let’s take a closer look at the formula to find out.

Should You Trust The Ingredients?

To be the best, or even an effective testosterone supplement, reliable ingredients are imperative. Here’s a brief overview describing a few key ingredients.

Tongkat Ali (Eurycoma Longifolia)(50 mg.) Tongkat Ali contains small peptides called eurypeptides. Research shows these peptides boost testosterone levels and improve sex drive.

Additionally, one study showed men with low testosterone levels experienced a significant improvement in “serum testosterone levels” and “quality-of-life parameters” after taking 200 mg/day tongkat ali for a month. [1]

With 50 mg tongkat ali, Adavanced Test-O-Boost likely doesn’t provide enough to be effective.

Tribulus Terrestris (100 mg). Tribulus terrestris contains saponins which stimulate the pituitary gland to increase luteinizing hormone production.

Research results for tribulus are mixed. One study with male rats suggests tribulus is an effective aphrodisiac and libido enhancer. Rats were given 2.5, 5 mg, and 10 mg/kg body weight orally, once daily for 8 weeks. [2]

However, a study on subjects taking tribulus for 8 weeks at 3.21 mg per kg body weight daily revealed, “Supplementation with tribulus does not enhance body composition or exercise performance in resistance-trained males.”[3]

Furthermore, the tribulus featured in a serving of Advanced Test-O-Boost (100mg) doesn’t come near dosages used in both studies.

L-Arginine (300 mg). Arginine naturally increases nitric oxide production, the primary messenger responsible for getting and maintaining and erection.[4]

Experts recommend taking 5 g arginine daily to improve erectile dysfunction. [5]

Unfortunately, Advanced Test-O-Boost only provides 300 mg arginine, which is much smaller than the recommended amount for erectile dysfunction.

Zinc (50 mg). Zinc is an essential mineral and plays an integral role in several enzymatic processes. Furthermore, zinc supports a healthy immune system and testosterone levels.[6]

Is Advanced Test-O-Boost Toxic?

Advanced Test-O-Boost exceeds the upper tolerable limit for zinc by 10 mg. Excess zinc consumption over a period of time leads to zinc toxicity. Side effects from this include nausea, vomiting, diarrhea, and headaches. [6]

Should You Go For the Trial?

You can receive a 30-day Advanced Test-O-Boost supply for the shipping and handling cost ($4.95). However, the trial period only lasts 14 days. Unless you call to cancel, the credit card on file will automatically be charged $59.95 for the bottle.

What’s more, this automatically enrolls you in the auto-ship program. You will continue to receive Test-O-Boost and be charged $59.95 every 30 days until cancelled.

An individual 30-day Advanced Test-O-Boost supply can be purchased from the official website Store.Niwali.com for $67.00.

Final Thoughts on Advanced Test-O-Boost

While Advanced Test-O-Boost features ingredients shown to effectively boost male enhancement performance such as tongkat ali and arginine, the dosages are insufficient to significantly improve performance.

I recommended passing on Advanced Test-O-Boost until a reliable source with customer reviews surfaces, or the price drops.
