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.

I have been taking this along with the Signature Series CLA for about a month now. Since I started both at the same time, it's hard to say which has had more of an effect. I feel that they have helped my horrible sweet tooth and even though I haven't lost weight, I feel as though my body composition has improved even while carrying a few extra lbs. Would definitely recommend.

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 feel like this has helped my recovery after workouts. The downside is that it messes up my stomach.

50/50 on this product. I do see benefits as it does help recovery and weight lose, but I seem to reek the negative effects of this as the web as backed my research. I get stomach pains, frequent bathroom visits, and occasional headaches.

I have been taking this along with several other Signature products daily for weight management and supplementing my training. This product along with the others has allowed me to not only lose weight and gain lean definition, but allows me to workout consistently daily at a high level.
