You probably know there are issues and side effects that come with testosterone boosters, especially prescription testosterone medications.

But what people are saying about Syntheroid makes it one of the most interesting testosterone boosters currently on the market today.

Some folks will tell you they’re either not worth it or to wait until you’re pushing 40 before to even considering taking a testosterone booster.

But that’s not what people have been saying about Syntheroid. People really seem to love their results whether they’re primarily taking it to enhance their workouts or to overcoming declining testosterone levels as they age.

There is proof that testosterone boosters do work and some can definitely help no matter your age to increase muscle mass, enhance energy and improve strength. Keep in mind that a testosterone booster like Syntheroid is designed to induce, or stimulate the body into producing more testosterone, not replace it.

Testosteorne boosters have always been popular among body builders – which is about two-thirds of our readers – because they can help create and maintain muscle mass. But they can also increase your libido levels if that’s a concern of yours and help you feel more energized even as you age.

So of all the testosterone boosters, do we like Syntheroid? Is it has the whole package: solid ingredients, well-respected manufacturer, and a good consumer support system?

Of course you can find out more and order by visiting the official site by clicking here.

Ingredients in Syntheroid

Let’s look under the hood and see what drives Sytheroid

A couple of things to point out here.

650 mg of Tribulus Terrestris. You just went from a minivan to sports car. 650 mg of the best testo boosting ingredient is a really good thing. TT works by infusing a luteinizing hormone into the body, which then stimulates testosterone production and all the positives that come from that. The ingredient has been around for about 20 years or so and is still kicking. The key here is the punch from Syntheroid is gonna be greater because of the strong dosage of TT.

300 mg of Testofen. Again, the right amount. Testofen is an extract from the fenugreek seed, which contains a number of testosterone boosting saponins. These saponins are important in the development of free testosterone in the body. You see this supplement used in a number of boosters.

250 mg of Aminogen. Some might wonder why XPI included such a strong dosage of Aminogen because it actually doesn’t directly help with muscle building.  Rather, it’s designed to maximize potential. Aminogen is often included in supplements as a way to increase energy, support muscle growth/maintenance, and prevent soreness. Aminogen also supports healthy nitrogen retention by giving the lifter immediate bursts of energy while also protecting the muscles from damage.

Everything else in the formula is what it is; there’s nothing really to note. I do like that they include at least 100 mg of even the least significant ingredient. Syntheroid packs a punch – not the sissy, schoolgirl you-said-what-about-me kinda of punch. Think Ali here.

We should also mention the final ingredient, BioPerine; this guy helps deliver all the supplements in Syntheroid’s formula to the all the right places. It acts like a more efficient UPS truck making sure things get to where they need with full impact.

Consumer Treatment

Consumer treatment is where we examine how the product manufacture takes care of the consumer’s needs. We rate everything on a scale of 1 to 10, with 10 being the obvious best. For the most part the consumer is treated quite well on Syntheroid; but we do have a few minor bones to pick.

Website: 10

The website is informative and detailed. All the key links like hotlines, customer chats, guarantees and product information are right there and easy to find. Here’s what their main page looks like right now.

In our estimation, this is the trifecta coming together: a hotline, guarantee information (both located at the top of the page) and good supplement information (can’t see it from the screen capture above, but you can see it on their home page). Also they deserve a gold star for publishing their ingredient profile and avoiding a massive proprietary blend.

We always like video so props for the testimonial. We don’t want to make a big deal out of a testimonial because let’s be honest these can easily be doctored. Always take them with a grain of salt. But more importantly a well-produced video tells me the company is invested in the product and I guess adds a sense of legitimacy.

Here is the testimonial video they have uploaded on their site:

If you’ve ever browsed the web for supplements you know there are A LOT of shady companies out there. Good website, videos, customer support all are strong indicators the company is at least attempting to be reputable – which what you see here with Syntheroid.

Customer Service: 9

The number is right on top of the home page. Took under 30 seconds to get a rep on the phone and he was informative. The guy did seem to be a little robotic in his responses but I got all my questions answered.

Money-Back Guarantee: 9

Syntheroid offers a 90-day satisfaction guarantee. Companies used to offer lifetime money-back guarantees, but I don’t see that as much any more. The new norm seems to be 30-day guarantees so for Syntheroid to offer a 90-day guarantee is triple what most companies offer.

Our Opinion of Syntheroid

Yea, we like Syntheroid. I think you got that from the review. Supplements are such a crap shoot anyways that it’s really hard to find something legal and over-the-counter that works in the 80% – 90% range for consumers. But your chances of getting a dud are less when you buy a good supplement like Syntheroid from a quality company like XPI.

In full disclosure we have a small man crush on Syntheroid. Sorry, but it’s hard not to get a little twittered when you take a look at the product. As far as testosterone boosters go, we haven’t found anything better – especially for the very competitive price of $59.95.

As far as testosterone boosters go, Syntheroid is your best bet. It’s also priced very competitively at $59 a bottle. You may even be able to find something slightly cheaper if you look hard. We’ve found the best place to buy Syntheroid is at

I am a serious Martial Artist with Black Belts in three different arts, an instructor,bodyguard, and a retired Marine. I first tried Syntheroid and noticed an improvement within one week, greater reps, more energy, explosive power that continued to increase each day. Then I order another bottle and upon receiving it noticed the ingredients were different. I took about 10 days worth and was like what the …? Their customer took great care of me and suggested another product that sorry to say didn’t do anything. Now in looking at the ingredients again in each bottle, I will be ordering more Syntheroid. This is a great product if they keep the ingredients the same, like what it is composed of now. People do research into what your putting into your bodies, it’s fuel, it’s an octane booster, you would put crap into your car or truck, so why into your body.

Yes, I recommend this product

Syntheroid isn’t primarily a fat burner, however increasing testosterone can help you lose weight as it helps increase your energy levels. It shouldn’t lead to weight gain but helps you burn fat while building muscle easier. Just be sure to work out regularly and eat right of course.

I have tried syntheroid, and I think this stuff is AWESOME! I am 45, and my strength has shot through a roof like I am 17 again! My bench is up, my pumps are insane, and I feel like I can deadlift a mac-truck! I shook my friends hand the other day and he said I had a grip like a vise, and wanted to know what kinda stuff I was on?! I;m benching 215 first time in my life!

I was on P-6 before trying this. I WILL NEVER GO BACK!! I have tried many test power/pill type stacks. I tend to keep my protein/vitamin/and GH booster the same but I was looking for a would Jon- negative side effect causing T Booster (hard to find). Well I found the one that works best. I wake up in the morning after a bicep workout and I have an eight pack protruding as if I did an AB routine. Amazing product. I bought a 3 month supply. Works best with Myoswell which is the Kreakalyne partner to it.

I’ve been climbing trees and dragging brush and lifting logs for 4 years now and did gain muscle and about 20 pounds. But my body seams to be used to that routine and I have been feeling burned out faster in the last year. My neigbor mentioned it to me and I tried it. Since taking Synthroid for 3 weeks now when I get realy sore its only for 1 day instead of 2 and I don’t burn out so fast. I’m back to my old ways of going the extra mile lifting logs to get that workout and I feel good about it at the end of the day. A couple of my co-workers noticed the difference and ordered it also.

Iv been on sytheroid for about two weeks now and i can say that this product is the real deal, dispite all of the negetive hype about tribulis not working. Internet B.S. is prevalent every where all the time. This is a good product. A word of advise/ dont try Force Factors test x 180. 30% gensing. Red Flags in my eyes.

Just took my first 3 week cycle of Syntheroid, and I have to say it works for me. Low testosterone levels run in my family, and I can tell at the age of 32 that I should have more energy than I have now. I feel great, my mind is sharper and I have seen results in the gym for sure. I highly recommend this product to those who needs a little extra kick in their life. No side effects for me!

I have been taking syntheroid for only a week, and all ready see a huge difference. My muscles have become soo much harder with every day I lift. I can really tell this is a genuine product that stands by its word. Cant wait to see the end results. Also on the plus, your sex drive becomes that of when I was 17!
