Whether you’re looking to build muscle, increase strength, or maximize libido, Testosyn is advertised as the #1 testosterone booster to accomplish it all.  Its all-natural formula consists of several patented and clinically proven ingredients used to increase testosterone.

Increasing testosterone makes workouts more effective. According to the official website, Testosyn “dramatically increase[s] athletic performance,” “maintain[s] your libido while dieting,” and “promote[s] muscle mass & strength.”

To find out if Testosyn delivers reliable results, I researched its ingredients and examined the latest customer reviews.

What’s In Testosyn?

Ingredients ultimately determine a product’s effectiveness; Testosyn is no exception.

Immediately, I noticed the individual ingredient amounts are disclosed. While this doesn’t guarantee effectiveness, it helps users understand how Testosyn works. Let’s take a look at a few of the most effective testosterone-boosting ingredients.

D-Aspartic Acid (1560 mg): D-aspartic acid is an amino acid that raises testosterone levels.

Aspartic acid is usually given in doses of 2000-3000 mg daily.[1] Testosyn doesn’t contain this much but should still provide amazing results.


Eurycoma Longifolia (100 mg): This plant extract lowers the SHBG protein, which binds to testosterone. When it is lowered, there is more testosterone available in the body.

The correct dosing amount depends on health factors such as age, weight, and height. Testosyn likely contains enough to have a positive effect.

Tribulus Terrestris (100 mg): This natural herb is used to increase libido and stimulate testosterone production. It is not a hormone but effectively enhances athletic performance particularly because of its potency. [2]

Horny Goat Weed (100 mg): Even the name gives away the purpose of horny goat weed: this herb is a powerful sexual stimulant that increases libido and improves performance.

There is not an established recommended dose, but Testosyn should still offer enough to be effective. [3]

BioPerine Black Pepper Extract (10 mg): This patented blend is derived from black pepper. It is an excellent absorption supplement, meaning it helps Testosyn’s other ingredients absorb more effectively into the body.

FenuSterols (300 mg): This patented form of Fenugreek contains FenuSterols, which have an anabolic effect. It increases muscle mass, strength and endurance.[4]


Tribulin (400 mg): Tribulin was made specifically to increase natural testosterone production. This trademarked ingredient was made with 20% standardized saponins to maximize testosterone production. [5]

Supp facts

Is Testosyn Safe to Use?

One of my first concerns when using any supplement is safety. The best way to determine how it might affect the body is to look at how users have responded to it.

According to some customers, Testosyn delivers results without causing unpleasant side effects.

“This product met my expectations! I saw results within the first two weeks. I recommend this for bodybuilders looking to get to the next level.” – J,

Based on customer feedback, Testosyn seems safe for most people.

Pricing Options

High quality testosterone boosters like Testosyn often cost more than you’re willing to pay. But if it works, the retail price of $95.95 might be worth it.

Lucky for you, deals are offered regularly so you don’t have to pay an excessive amount. On the official site you can find Testosyn for $59.95. This is a fantastic deal compared to the retail price.

Other sites such as sell Testosyn for as little as $59.95 a bottle.  And, regularly has it for $40.00.

One benefit to purchasing Testosyn from the official website is the 90-day money-back guarantee. If Testosyn doesn’t live up to expectations, return one used bottle for a refund.

Maximize Results

The product label gives instructions for achieving maximum results from Testosyn. A full serving (3 capsules) should be taken once daily.

Many users report that within as little as three days they noticed an increase in strength, lean muscle mass, and libido.

For the best results, consider implementing a few strategies to naturally increase testosterone levels. Exercise and a healthy diet are two factors that play a vital role in testosterone production.

Should You Try Testosyn?

Testosyn uses a high quality formula containing clinically proven ingredients. However, it’s potent formula is not for everyone, so it’s best to exercise caution when you first start using Testosyn until personal tolerance is determined.

A video testimonial from Josh Dahl is posted on the official website. He claims to feel 10 years younger and is satisfied with his results after using Testosyn. His testimonial, along with the hundreds of reviews from real customers who are satisfied with their results suggests Testosyn might be a testosterone booster worth trying.

Phil Hale Says:

No, but have a question. Am already taking benicar and g. e. hydrochlorothiazide for blood pressure, will I have any kind of reaction mixing these with Testosyn?

March 28, 2013 at 2:43 pm

admin Says:

Phil, Testosyn contains ingredients which affect blood pressure levels. Combining it with medication may increase your side effect risk. Just in case, it’s best to consult a doctor before using Testosyn.

Jeff Spicer Says:

Iam 68 yrs old and not supposed to have any testosterone according to my M.D. that is to say 200 is normal for my age have been useing Testosyn and the accompanying HGH testosteron has increased about 50pts not sure which did the deed but believe a younger person with something approching normal testosterone could build up to a good muscle development level when useing the products in tandem.

Not so much of a comment as a question. Does this product increase DHT levels?

Todd Says:

I am 38 years old and I have used Testosyn now going on my second bottle. I noticed an immediate increase in overall strength within a few days. I would definately recommend a good diet though because you find yourself wanting to eat and you don’t want to be unhealthy. When taking Testosyn initially I was able to get my bench press back up from 185 to 280 in 2 weeks after having been away from the gym for about a year. Something I would definately recommend. Best thing I have tried so far.

Lonnie Says:

I was a COMPLETE skeptic, when I first ordered this product, but I am a born again believer now. Within 3-4 days there was a VERY noticeable difference: Strength increase, stamina increase and libido increase. Not to sound too much like a commercial; but this product literally did everything that they claimed it would. I purposely didn’t order my a second bottle to see if there was actually a difference. Let me tell you; after about two weeks, I ordered that second bottle and will go back for a 3rd, 4th etc… I told my friends I would not recommend it until I knew for sure it wasn’t just a placebo, well friends, I highly recommend it. Even for skeptic; I say, try it. With little or no side effects, you have nothing to lose and everything to gain?

I recently began pro-hormones. I have developed the following regime. 1 – Andro and creatine prior to my routine. products like X factor to aid my protein absorption, and growth hormones before bed. Is this a sound rotine with heavy lifting.

September 1, 2013 at 9:05 pm

admin Says:

Matt, that sounds like an excellent routine – keep it up! You’ll want to consult a doctor just in case, however.

T. Preston Says:

Do you have to cycle off Testosyn as with other hormone products such as P6 from Cellucor?

September 5, 2013 at 6:51 am

admin Says:

T. Preston, you should cycle off Testosyn for 4 weeks after 12 weeks of use.

Michael Says:

I take 125 mcg of Testosyn daily for my hypo thyroid. Does Testosyn affect the thyroid gland ?

September 6, 2013 at 8:09 pm

admin Says:

Michael, Testosyn is not the same of Synthroid. Testosyn is a natural testosterone booster and does not affect the thyroid gland. Additionally, you should not use Testosyn in conjunction with prescription medications without the approval of a doctor.

David Says:

I saw the doctor because I do not feel like I have any engery, no motivation, and just plain do no enjoy doing things, anything, anymore.

I was tested and found that i have low testisterone levels andI was prescribed Fortesta. I stopped taking it because I do not like the way I feel and act while on it.

I’m not looking for something for work- outs, as I do not work- out. I just want something that will help me enjoy life again.

Louis Says:

Using Testosyn at 57, gave me an incredible boost of energy and power during workout. I feel 25 again.
However, I read a medical article which reveals that D-Aspartic Acid increases the testosterone level but also causes the body to produce more aromatase which converts testosterone to estrogen in the body.
Please, I would appreciate your comments about that. Thank you!

September 27, 2013 at 11:15 am

admin Says:

Louis, it’s true DAA may increase aromatase, which is why it’s important to include an aromatase inhibitor to counter this effect. Even something as simple as a resveratrol or zinc supplement can be taken alongside Testosyn to amplify its testosterone boosting effects.

September 27, 2013 at 12:17 pm

Louis Says:

Thank you for your quick response. May I suggest that aromatase inhibitor should be added in Testosyn composition!

October 6, 2013 at 8:47 am

admin Says:

That is a good suggestion Louis! If we had any input on the Testosyn formula, then it would be there in a heartbeat. However, we’re just a review site – we don’t actually make or sell the products.

Mike Lanning Says:

Have been using Testosyn for about a week now and haven’t gotten the kick that I expected. Am taking 4 capsules per day. What should I expect?

November 4, 2013 at 9:20 am

admin Says:

Mike, it takes some individuals longer to respond to Testosyn than others. For best results, use the entire bottle. If it doesn’t give you results by then, contact customer support for a refund.

November 4, 2013 at 11:53 am

Charles Says:

I am 57 and weight train. I have not used Testosyn but I do take the real deal and think I am having a problem with high bold pressure. I have taking test for about 4 years because my body stopped making it. I am now looking for something that is safe and gets the results I am used to.

November 10, 2013 at 6:21 pm

Tim Says:

Can the Admin respond to David’s question from September 13th please. I have the same question. Thanks.

November 12, 2013 at 11:33 am

admin Says:

Tim, Testosyn provides a great boost in energy – which may help users find a little extra motivation to do things and improve quality of life (or as many users have stated, to improve workouts). Additionally, low testosterone often results in feeling little lackluster, so Testosyn may help you there. However, it doesn’t contain ingredients that alter mood to “make” you feel better.

November 13, 2013 at 12:53 pm

bruce coleman Says:

charles,you won’t get the same results with a test booster as you do with roids or pro-hormones.Just don’t get your hopes up.They do work well, especially for off cycle.

Bryan Says:

will Testosyn raise blood sugar levels?

December 1, 2013 at 7:51 am

admin Says:

Bryan, Testosyn shouldn’t have an impact on blood sugar levels though it does have an impact on blood pressure. If you’re concerned about its effects, ask your doctor before taking it.

Jake Says:

I need to know if there are any stimulants in this product..I am highly sensitive to them.I can,t even do any caffeine!

December 22, 2013 at 7:27 am

admin Says:

Jake, Testosyn does not have any stimulants.

daro blankenship Says:

i am reading testimonies and have seen several questions answered saying that Testosyn does affect blood presure. My question is does it lower or raise blood pressure

Thank you for a quick response

January 3, 2014 at 6:15 pm

pumpkinpierose Says:

Daro, many of Testosyn’s ingredients are known to lower blood pressure.

James Says:

I am a late 20’s male, i have been experiencing low energy levels and have had problems performing as well as an increase in fat even with regular exercise. would something like this help me?

January 4, 2014 at 9:30 pm

pumpkinpierose Says:

James, Testosyn is a great tool for all of those problems. However, it’s best you ask your doctor for advice first.

January 6, 2014 at 12:38 pm

Keith Says:

So, I’m a little confused! Does Testosyn have an estrogen blocker or not? Would I need an estrogen blocker while using this supplement? I’m ver interested in trying this supplement.

January 12, 2014 at 7:33 pm

pumpkinpierose Says:

Keith, as far as we can tell, Testosyn does not block estrogen but rather focuses primarily on increasing testosterone. As mentioned in another comment, it might be good to take zinc or resveratrol alongside Testosyn to optimize its effects.

I am 57 , and for the past two yrs. I have experience low desires and performing in the bedroom, I have border line high blood pressure , I check with my doctor and told me my testosterone level was 280 I need help , with my desires , and I will be taking training at a new gym . will this Testosyn help ?

January 23, 2014 at 1:48 pm

pumpkinpierose Says:

Joseph, Testosyn may help but with your condition it’s best you ask your doctor before using it.

steve Says:

I just want to ask a couple questions. In the review it was mentioned that the serving was 3 capsules, but on the bottle it says to take 4 capsules. Which is it? Also I found the times offered to take the dosage were very vague. The company has 4 different times it says it can be taken, all said to be the best times. So, on days that I don’t workout- take that dose first thing in the morning, then on work out days, take it before a workout. Would that be the best way? Thanks for your time and consideration.

January 29, 2014 at 3:26 pm

pumpkinpierose Says:

Steve, always follow instructions as they are listed on the label. occasionally reviews become outdated and the product is changed by a little bit before we can update our content. If you are worried about when to take it, customer service is provided at where you can chat with a live representative. But, it sounds like you have the right idea as to when to take it.

Diane Says:

Recently my husband has lost interest in everything. He has no energy, desire to get out of bed and libido is very low.His blood work showed very low testosterone. The doc started injections. Can he take Testosyn while getting injections? It just seems injections take a long time for resuls. Thanks so much.

January 26, 2019 at 9:27 am

It’s difficult to say, as we’re just a review site for these products. However, the Testosyn website promotes a 90-day money-back guarantee. So, it’s worth a shot.

May 29, 2019 at 3:59 pm

Tracy Says:

Can women use this product? Or do you have a suggestion on one that women can use that would be beneficial to muscle/strength building?


April 16, 2019 at 8:56 am

Admin Says:

There’s nothing that we’ve found that suggests this product might not be effective for women. The Testosyn website promotes a 90-day money-back guarantee, if you’re not satisfied with your results.
