“With higher levels of testosterone, you’ll be ready to dominate your workout!” explain manufacturers. “Testosterone is vital for those looking to increase muscle mass, strength, and to improve muscle tone and definition.”

These are some pretty weighty claims, so I did a little digging to see if Syntheroid could carry the load.“

What Syntheroid Has to Offer

A supplement is only as good as its ingredients. Fortunately, Syntheroid brings a lot to the table when it comes to a clinically proven formula:

Tribulus Terrestris

Tribulus terrestris contains steroidal saponins which increase testosterone production. According to a 2000 study, researchers found androgen precursors in tribulus terrestris and additional ingredients enhanced testosterone formation. The combination also reduced androgen-estrogen conversion.


This patented fenugreek seed extract contains phytochemicals which improve metabolism, increase libido, and lower cholesterol levels. Studies show fenugreek extract coupled with physical exercise increases free testosterone levels significantly.


A naturally occurring ecdysteroid hormone, this ingredient boosts athletic performance and stimulates protein synthesis. According to animal studies, phytoecdysteroids increase growth and physical performance, though human research still needs to be conducted.


Created by Triarco Industries, Aminogen increases amino acid levels and nitrogen retention. Furthermore, studies show Aminogen enhances protein absorption. By enhancing protein absorption, your muscles have the basic building blocks for growth and repair.

Coleus Forskohlii

Coleus forskohlii increases cyclic AMP production, which in turn boosts energy levels and increases fat metabolism. In a 2005 study, researchers found coleus forskohlii favourably alters body composition while increasing bone mass and free testosterone levels in obese men.

Alpha Lipoic Acid

ALA prevents cellular damage by eliminating free radicals. Additionally, ALA may protect against cardiovascular disease.

Eurycoma Longifolia

Animal studies suggest Eurycoma Longifolia increases testosterone production. This results in greater muscle strength, bone density, and sexual performance. Human trials still need to be conducted.

Horny Goat Weed

Horny Goat weed contains the phytochemical Icariin, which mimics testosterone’s effects. According to researchers, “Icariin improved the condition of reproductive organs and increased the circulating levels of testosterone.” As an added bonus, it stimulates libido, relieves fatigue, and may even reduce high blood pressure.


Although Bioperine does not have an impact on testosterone or muscle performance directly, this black and long pepper extract enhances bioavailability of other ingredients, making them more effective.

Is Syntheroid a Steroid?

Due to the similarity in name, many people assume Syntheroid is a steroid. Although Syntheroid does increase testosterone, it does not achieve this affect through synthetic testosterone or other dangerous chemicals.

Rather, Syntheroid is all-natural and safe to use. It should not test positive for steroids. Syntheroid is NOT Synthroid. Once again, there is a lot of name confusion with Syntheroid and Synthroid.

Synthroid is a prescription drug also known as Levothyroxine, which treats hypothyroidism. Although Syntheroid regulates hormones, its ingredients and mechanisms for optimizing your health are completely different from the prescription formula. And, it doesn’t require the hassle of a doctor’s visit!

Potential Risks

Syntheroid does not contain any hormones, prohormones, or dangerous ingredients, so you can use it regularly without worry.

However, consumers should approach Syntheroid with caution, as it does pose a risk for allergic reaction. Be sure to read the ingredients carefully before trying Syntheroid.

Additionally, Syntheroid contains ingredients that react negatively with certain medications. Consult your doctor to see if Syntheroid is right for you.

What if It Doesn’t Work?

If you order from the manufacturers at XPI Supplements, your purchase is backed with a 90 day, no hassle, money back guarantee. If you are not satisfied contact customer support on how to return your order.

Do You Still Have to Exercise?

Syntheroid creates the ideal environment for building muscle and improving athletic performance, but it cannot compensate for a poor lifestyle. To maximize your results, participate in regular exercise and eat a healthy, well-balanced diet.

Product Pricing

You can find Syntheroid on a few different sites; I prefer buying it from XPISupplements.com because when you do order there, you also get a 100% Money Back Guarantee. So, if you don’t like your results, you can send it back for a refund. Here are a couple other places you can order:

  • Amazon.com

  • eBay.com
