While researching Testosterol, I couldn’t help but notice the lack of information. It’s true that Testosterol isn’t the most popular testosterone booster. However, experience has shown me that “popular” doesn’t equate to “best.”

So, I gathered the scanty information on Testosterol and here’s what I learned. I hope it’s enough to help you decide if Testosterol is “best” material.

What Makes Testosterol Work?

Testosterol increases testosterone using a Testosterone Support Complex:

Aminobutanedioic Acid (AA) – increases luteinizing hormone (LH) levels up to 33% and testosterone levels up to 42%. [1] AA is also known as D-Aspartic Acid.

Tribulus Terrestris – supposedly increases luteinizing hormone, which stimulates testosterone production. [2]

Fenugreek – contains saponins (natural steroids). Research shows that fenugreek increases testosterone, boosts libido, and enhances strength. [3]

Avena Sativa – makes free testosterone more available. Free testosterone boosts libido and promotes muscle growth.

N-Methylglycine – stimulates NMDA receptors to increase testosterone production.

Eurycoma Longifolia – enhances testosterone production. Eurycoma promotes weight loss, maintains muscles, and boosts libido, too.

Unfortunately, testosterone levels don’t always stay high. Testosterol maintains high testosterone with an Estrogen/DHT Reduction Support blend:

Beta Sitosterol and Saw Palmetto – prevent testosterone from converting into estrogen or DHT (aromatase).

Pygeum – contains Beta Sitosterols.

Linum Usitatissimum and Chrysin – contain phytoestrogens, which inhibit aromatase. [4]

Quercitin – inhibits aromatase and promotes prostate health.

Resveratrol – prevents prostate cancer cell growth.

Testosterol Dosages

I don’t know what dosages Testosterol uses. All the ingredients are combined in a proprietary blend totaling 630 mg. Since individual dosages are hidden, I can’t see if they are safe and effective.

Is Testosterol Safe?

Testosterol has safe ingredients, but I don’t know if it has safe dosages. Because it uses natural ingredients, Testosterol is safer than synthetic testosterone boosters.

Testosterol is safer for some men than for others. For example, Testosterol may not be safe for men taking certain medications or with health issues. A doctor can tell you if Testosterol is safe or not.

How to Get the Best Results

One bottle holds 120 capsules. I couldn’t find out how many you are supposed to take each day.

Testosterol boosts testosterone, which enhances muscle growth. But your muscles won’t grow without exercise. For best results, lift weights regularly and eat a healthy diet while using Testosterol.

Is Testosterol Affordable?

Testosterol costs $109.99 on www.seinutrition.com. If Testosterol lasts 120 days, this is a good deal. However, I don’t know how long Testosterol lasts. If it only lasts for 30 days, Testosterol is expensive. Also, SEI Nutrition does not have a return policy.

I couldn’t find Testosterol on other retail sites.

Is Testosterol Worth Buying?

I like Testosterol’s ingredients, but everything else about it concerns me. Dosages are hidden, so I can’t see if they are safe and effective. Testosterol does not have an official website. Only one site sells Testosterol and it’s expensive. Lastly, it’s difficult to find basic information about Testosterol.

I don’t recommend trying Testosterol. There are dozens of better testosterone boosters on the market. Find one with safe, effective ingredients and dosages.

Justin Says:

I’m currently taking D-Testosterol TS, the dosage is 3 caps per day for 5 days, then 2 days off. Thus giving you an 8 week supply. I’ve just begun taking it this week so cannot say how effective it is, I’ll come back in a couple weeks and give an update. This was highly recommended to me by my trainer and forums that I frequent…

It is available at GNC. You say there are better but you do not name any. Which would you chose.

Dan, for starters, you could look at the top 10 recommended testosterone boosters reviewed on this site. Those would probably be a better option.

I took this last month and loved it. I would compare it to syntheroid a product by the same same makers as your number 1 test booster. It does everything, fat loss, gain strength, increase energy and libido. I have only taken 4 test boosters in my life and along with syntheroid this is the best. I had just ok results with test x 180 and didnt see any results from high t blackm
