Product Overview

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.*

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.

Bodybuilding.com Athlete

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.

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!

Not really noticing any results after 3 weeks of using and following the directions.

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 BB.com 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??

I’ve never used Test Boosters before this and I was impressed. I take it 30 min before my workouts and I feel the difference. Would recommend trying due to its good price.

This product was great for lowering stress levels and as a result boosting testosterone. This has been a game changer as I work an intense, sometimes erratic, and long day. Highly recommend to anyone who may a excess stress. Outside of the day to day, I do inentense weighted cicticuts, spiking my heartrate up to 193 beats per minute sometimes. This has been the only change and It has been a game changer!
