Bodybuilding.com 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.*

Bodybuilding.com 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

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, Bodybuilding.com 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.

TOTAL TRANSPARENCY

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.

EFFECTIVE DOSES

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.

RESEARCH-BACKED INGREDIENTS

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 not tried this product, so I cannot attest to its effectiveness. This review is to correct the total misinformation from DanWL’s comment below... Ca + Zi + Mg in a supplement like this, does NOT hinder absorption of each other as they are in balanced dosages. Ca will only hinder Zi absorption (and vise versa) if one is taken in substantially higher dosages than the other. Conclusion: While I cannot attest to the effectiveness of this product, I can however set the record straight on the minerals in this supplement’s formula. At the doses that are contained within this supplement, you will have no negative affects on absorption between the minerals if taken as directed and with a healthy diet.

Took about 10 days of consistent consumption for it to start working. And then I was extremely *****, 24/7. Thank God I have a gf or I would've definitely contracted something. It was like a thirst that couldn't be quenched. Like 7 times a day, for the entire cycle. I stopped going to the gym, because I was getting plenty exercise in the bedroom, and also have a physically demanding job. I didn't gain anything, but I definitely cut a lot of fat. Will use again, 10/10. When I'm ready for another cycle anyway

This is my first test booster, so can't compare how it works with others, but in terms of having used it for almost a month, I gotta say that I did see results. I don't think I gained much muscle or gotten incredibly stronger, but my main focus was using it for recovery, as I would take one serving after working out. Recovery was great, would sleep better and feel way more relaxed and calm. On days when I didn't work out I would take a serving in the morning and my full day I felt very calm and able to deal with any of life's challenges. Also, it made me ***** as hell which was awesome. Haha. Overall I say it's a great product. I haven't noticed any side-effects and I'm worried on long term effects on using this though, so I'm thinking of cycling for 2 weeks off. Anyways, ask your doctor would be my advice, and If they say there is no harm then I highly recommend this product.

This has pros and cons but overall I would say it's mildly effective. It's not a miracle pill. I may have been hoping for more. I do see a little bit more energy throughout the day, but I am not noticing more energy or strength during workouts. It's not allowing me to up the weights. The Fenugreek has a maple smell. Trust me, this smells stays with you. Scrub your hands after you take it. It's not a maple smell that makes you think of pancakes. Also, when you and your partner are getting cozy and she decides to take care of business a little south, she will smell it. On that note, I have noticed stronger salutes. Overall, it's not bad. It doesn't claim to be a miracle pill. It may affect people differently. I will continue this bottle. It doesn't make me jittery or any weird side effects like I've had with other brands, so I may continue. Give it a try.

I have been using this product for years and I will never stop. As some active and pushing 40, it’s extremely important to keep testosterone levels up. Since this product is full of natural ingredients I feel confident it keeps me strong and healthy with no side effects.

After taking the entire bottle and following the recommended dose, I experienced no change of any kind with this natural product. As a test booster, it had no effect.

This is one of those products that you can absolutely tell a difference when you take it. Even in as little as a week of taking this, i could feel positive changes. You'll never win that fight against father time but this stuff sure helps

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.
