Testosyn is attracting a lot of attention these days due bold advertising and marketing claims to be the “#1 Testosterone Booster.”

Supposedly Testosyn is designed to optimize testosterone levels, consequently resulting in a wide variety of benefits such as increased muscle mass and strength, improved speed and agility, and even an increase in libido.

However, does Testosyn deserve its place at the top of supplement shelf? Let’s see what it has to offer.

Ingredients in Testosyn

Testosyn makers call their ingredients “premium”. After researching these ingredients, I agree. Each one has either been clinically proven or patented; which implies high-quality and thorough testing.

Testosterone Advantage. Testosterone Advantage is patented calcium fructate extracted from natural fruits and vegetables. It optimizes testosterone levels within hours after ingestion by reducing SHBG protein. [1]

D-Aspartic Acid. Research shows d-aspartic acid plays a key role in the synthesis of LH and testosterone levels. It increases the release and synthesis of LH through the involvement of cGMP as a messenger.[2]

Eurycoma Longifolia. Euryocoma longifolia is a clinically proven aphrodisiac. It contains chemicals which improve sexual performance while promoting the growth of both ventral prostate and seminal vesicles. [3]

Tribulus Terrestris. Tribulus terrestris has long been a traditional Chinese herb for improving sexual function. New studies show TT improves sexual function and exhibits aphrodisiac effects. Researchers believe tribulus increases androgen production to achieve these effects. [4]

7-Keto DHEA. 7 Keto is a metabolite of DHEA. It is a hormone that can safely boost immune function and promote body fat reduction. Unlike DHEA, 7-Keto does not convert into estrogen and testosterone. [5]

AstraGin. AstraGin is a natural compound composed of astagalus and Panax notoginsseng. Studies show AstraGin increase nutrient absorption. [6]

Forslean. Forslean naturally increase energy levels and caloric expenditure, making it easier to slim down. Unlike other stimulating ingredients, however, coleus forskohlii does not act extensively on the central nervous system. Rather, it increases cyclic AMP production, providing the same results without the negative side effects.

Studies show coleus forskohlii may inhibit weight gain when used appropriately. [7]

Horny Goat Weed. This natural aphrodisiac contains phytochemicals which improve sexual performance and function. One chemical, known as icariin, mimics testosterone to improve circulating testosterone levels[8]

Alpha GPC. Alpha GPC is said to boost cognitive performance and memory function by improving acetylcholine production. [9]< Additionally, many experts believe Alpha GPC plays a key role in HGH secretion. [10]

Deer Antler Velvet. Dear antler velvet contains substances which may help cells grow and function. It is often used to boost strength, endurance, and immunity. Although many manufacturers claim deer antler velvet enhances sexual performance, there is not enough clinical research to verify these claims. [11]

BioPerine. BioPerine is a unique extract that works synergistically with other ingredients to improve their absorption.

The Facts About Testosyn

Manufacturers usually hide ingredient amounts so you can’t see exactly what they’ve used. Apparently, Testosyn makers have nothing to hide because they show everything. Quick research on the ingredients used in this product shows me that what Testosyn makers use is the right dose. In other words, these ingredients should be very powerful.

As one of the few male enhancement products that really is all-natural, Testosyn should be safe and unlikely to cause side effects. Most users don’t report any negative side effects from using it. What they do report is stronger erections, higher sex drive, and better sex after using Testosyn.

Is it A Steroid?

No. Testosyn is a dietary supplement that contains all natural ingredients to promote muscle building and strength. It does not contain hormones or pro hormones, and it will not test negatively on a drug test.

What About Side Effects?

Testosyn contains a wide variety of herbs in their clinically proven amounts, so you shouldn’t worry too much about side effects.

However, if ingredients such as ALA and Fenugreek may have an impact on blood sugar levels, which in turn can react negatively with certain medications. If you are taking medications, then you’ll want to consult your doctor before using Testosyn.

How to Use It

Each serving of Testosyn is 3 capsules and you are supposed to take one serving a day. To boost your testosterone levels, you don’t need to do anything more than just take your daily dose. If you want to take advantage of the enhanced muscle growth that Testosyn offers, you can combine this Holding men product with regular exercise.

Cost & Guarantee

I found that the best online deal for Testosyn actually comes from the official website. For the price of $59.95, you can get a month supply, plus a 90-day 100% Money Back Guarantee. With this guarantee, the retailers give you the chance to try Testosyn and if you don’t like it, you don’t pay for it.

The official site also promises to ship within one business day so you don’t have to wait any longer to boost your testosterone levels and improve your sex life.

Who Makes Testosyn

Testosyn is produced by XPI, a company dedicated to providing quality supplements for improving physical performance. While Testosyn is one of their top-selling products, XPI is also known for manufacturing leading formulas such as Myotein, Myonox, Xtreme HGH, and Liponox -all of which have received some fairly impressive reviews.

The company itself is based in Utah, and though there is little information about XPI itself, their products definitely stand out in in a crowd.

Our Opinion

Testosyn may not have been designed as a male enhancement product. However, based on my research of this and other products, Testosyn has what it takes to dramatically increase testosterone levels; which is what a top male enhancement product should do.

After thoroughly analyzing this product, I think that Testosyn will work for most guys who use it. If it happens not to work for you, just return it and get a full refund. Since it uses some of the best ingredients in the industry, I think chances are good that you’ll keep Testosyn around. Give it a try!

        As far as I can tell, there is no free trial for Syntheroid. However, you can try the first bottle risk-free when you order through Syntheroid.com – it’s backed by a guarantee, so if it doesn’t work then you can return it for a full refund.

      Robert, it’s usually not a good idea to combine prescriptions with supplements. To find out if it’s safe for you, you need to talk with your doctor.
