Product Overview Signature Testosterone Booster

Testosterone is the hormone that regulates a man's sex drive, fat distribution, bone density, and muscle strength — but, unfortunately, it declines with age and increased stress. Keep your body in its prime with our Testosterone Booster, which combines natural, clinically studied ingredients shown to support healthy testosterone levels.* Signature Testosterone Booster bottle

KSM-66 Ashwagandha

This herb has been used in Ayurvedic medicine for its testosterone-boosting properties for hundreds of years.* KSM-66 goes through a special extraction process and has been clinically studied and shown to support increases in testosterone levels as well as exercise performance and strength.* Signature Testosterone Booster uses the clinically proven 600mg dose of this unique herb to provide maximum benefit.*


Fenugreek is probably one of the most well-known herbs for testosterone support, and for good reason. There are multiple clinical studies linking supplementation with fenugreek to testosterone levels as well as exercise performance.* Watch out for non-standardized extracts: Signature Testosterone Booster’s is standardized to saponins, which are the naturally occurring compounds in fenugreek that are the “active” ingredient.

A signature is a promise. A symbol of your identity. Your mark on the world. In 1999, was founded on a single promise: Trust. It’s who we are and it’s in our blood. Our Signature line is built on the same promise. Every product is no-BS, transparent, filler-free, and formulated with effective doses of research-backed ingredients you can trust. We create the highest quality supplements, so you can focus on leaving a mark of your own.


Signature products are formulated with high quality ingredients at effective doses that we’re proud to share with you. We don’t hide anything in a “proprietary blend”, so you always know exactly what you’re putting into your body.


An effective dose is the amount of an ingredient that has been shown to deliver results. Some supplement brands add a sprinkle of an ingredient just so they can say it’s in the product. Signature supplements always include enough to get the job done.


Trendy, flash-in-the-pan ingredients come and go. But time-tested, gym-proven ingredients are what you need to help you achieve your fitness goals. That’s what you’ll find in Signature products because that’s what works.

Am 62 and was tired all the time and sometimes have trouble staying awake. Tried several things without luck. Tried this product for almost a week, energy is increased, no longer feeling tired and even seeing weight go down. No side effects.

As with any quality product, it takes sometimes weeks to identify whether they are effective or not. The ingredients in the Testosterone Booster are not made up of anything that is controversial. Just choice ingredients that are conveniently packaged together for a maximum synergistic effect. Taking all of these products together gives me a little boost that is similar to a strong cup of coffee. After 1 month and watching my calories, I am down to 188lbs. and my strength has not suffered. I usually gauge my strength on heavy Incline DB Press which I consistently use the 95lb DBs and BB Back Squats. As a note, after 25 years of lifting, I concentrate more on good form and keeping my reps semi-slow concentrating on the intended muscle group. Losing about 7lbs and this combination stack after 1 month, I have noticed better definition in my upper body, namely shoulders and arms. In my experience losing weight as we all know, we lose strength. This has not happened. I am going to finish this stack, take 1 month off and I will most likely buy again because the ingredients in each have what I want and need. The price is right, too. Over the years I have tried all the major fads and it has been an education. So, now I am very particular on what I spend my money on. Good food and high quality products that are not fads have helped me progress.

I notice I have a bit more endurance during workouts and as a bonus helps my focus immensely. There is a lot of published research on the benefits of Ashwagandha including stress, anxiety, and testosterone.

For me I noticed that this product, works better when you cycle it. 4-6 weeks on and 2-4 weeks off.

I definitely feel a difference. Will keep using it because the price is way better than a lot of stuff out there.

This is worth the money! Considering it’s just a test booster, and nothing more, I am pleasantly surprised with this product. Follow the dosage, eat clean and I’m sure you’ll see some real results. It took about a week before I could feel a difference, but I definitely did feel one. Give it a shot!

Better test boosters out there. Also why would there be calcium in this when there is zinc and magnesium!? The calcium will hinder the uptake of those important ones. This is known knowledge. Come on man!

This is outstanding product if you are over 40. I can feel the difference in strength and energy. If you are a young bodybuilder, don’t take it. Its waste of money. Invest on creatine and whey protein

Have been taking them for about two months and I like the results. I haven't had a drastic change, but I do feel more overall energy and motivation. It's a good product if you are looking for something that is no fillers and sound quality for a decent price.

Halfway through a 90 day run and so far have experienced no noticable effects, impact or feeling. I've tried numerous Test Boosters in the past and have always seen/felt a lift but honestly this one has been completely flat so far. The ingredients look phenomenal but simliar to the branded vitamins that I also switched to, I'm disappointed with the results. In the past with other products, I've experience a lift in energy, bravado & seen gains in the gym. I know that the placebo effect is always a consideration but I was extremely high on this product after reading the insight and honestly I could not tell any difference at all. I have at least felt/seen something from Animal, Alpha & JYM. EVL, True GRIT and this product have fallen flat & are a waste. I only give it a '3' because of the label, not the results.

Good stuff, I have definitely felt stronger and better since I started taking it. I'm just wondering if this product needs to be cycled??
