What's inside Sergeant Steel?

D-Aspartic Acid:  D-aspartic acid is an endogenous amino acid present in neuroendocrine tissues of invertebrates and vertebrates. DAA has shown to increase amount of testosterone released in the blood, increased testosterone leads to muscle growth. DAA also increases nitric oxide (NO2, NO3) production, promoting fast recovery after workouts. Studies have shown that D-Aspartic Acid can raise Testosterone levels by 42% after 12 days of consistent use.

KSM-66® Ashwagandha Root Extract:  Also known as Ashwagandha, this ingredient is an adaptogen which means it can assist in reducing anxiety.  Also it has shown to improve semen quality by increasing serum levels of Testosterone and Luteinizing Hormone (LH), while reducing levels of Follicle Stimulating Hormone (FSH). Ashwagandha also helps to reduce levels of cortisol in the body, a hormone causes the loss of muscle and increases in fat.

Mucuna Pruriens:  This ingredient acts as a precursor to Dopimine. Dopimine is thought to be involved in the mental processes like motivation, mood, attention, memory, voluntary muscular movement, and learning. Also research suggests that L-Dopa supports lean muscle growth and normal hormone levels in men and women.

Nettle Extract:  Also known as Urtica Dioica, helps to inhibit Sex Hormone Binding Globulin (SHBG) indirectly helping to boost testosterone.

Fenugreek:  This ingredient has demonstrated a significant effect on aspects of libido and helps to maintain testosterone levels. Studies have shown that the seeds of the plant were able to increase testosterone levels, strength output, as well as hormonelevels while helping to reduce DHT.

Shilajit:  A nutrient and mineral rich biomass containing many medicinal humic and fulvic acids that has been praised for years for being the best carrier of energy and nutrition to the human body. Shilajit has been shown in recent studies to help increase both testosterone secretion and stimulation.

LJ100:  A patented extract developed at Massachusetts Institute of Technology (MIT) for the treatment of sexual dysfunction and male fertility, also known as Tongkat Ali, it supports increased sex drive through multiple pathways, including through the influence of free testosterone sex hormone binding globulin (SHBG) and aromatase activity. SHBG is a protein which inhibits the circulation of your free testosterone by binding it up and making it unavailable - it also has been suggested to impact SHBG based on clinical studies. Studies have also shown it to have anti-aromatase properties similar to Formestane, which leads to decreased estrogen and increased testosterone.

Dehydroabietic Acid (DHAA):  Studies suggest that this strong ingredient has great anti-estrogen effects. It binds to the aromatase enzyme to help prevent the conversion of testosterone to estrogen. It also boosts the production of adiponectin, a protein hormone that supports weight loss. As a matter of fact, lowered levels of adiponectin correlate with obesity. Therefore, this ingredient may help enhance body composition while helping decrease estrogen.

Tribulus Extract:  The very commonly used testosterone boosting ingredient in which a recent study showed that this extract increased users testosterone levels by 12% and IGF-1 levels by 20%.

Maca Extract:  A member of the broccoli family that has been shown to assist and improve fertility through increased production of sperm. In addition, Maca helps to inhibit prostate growth by supporting decreased conversion of testosterone to DHT.

Boron:  An essential mineral required by the body for bone growth and also has been shown to help reduce SHBG levels therefore promoting increased testosterone levels.

First, Assault Labs is one of the few nutrient providers, whose products do what
they say they will do. I have every faith is Assault Labs and if I react to something its because the product did what they said and I mis-used it. (that hasn't happened) Second, I feel it is too early to judge Sgt. Steel, but so far the Product does function as they described. I find it amazing when you follow Assault Labs information. D.V.B.

Quality grade

I can honestly say that this product works. I am a real everyday customer who relies on this product to power through my workouts after a long day of work. I highly recommend serious lifters to try it!

Well I'm 45 and was looking for something more natural that was a testosterone stimulate. I researched and making a long story short, I 1st bought DAA MAX( D-aspartic acid) but kept researching.
I found Sgt Steel. I have Been taking it for couple weeks now( I have stopped taking the DAA MAX due to Sgt steel having the same the D-asparticAcid in it same dosage)
N-E- Ways i must say my libdo(sex drive) has went to every night and any morning she's game. My confidence and mental determination and focus is out of this world.
I say that it's worth the try.
DAA MAX is good you all, but Sgt Steel is DAA MAX Plus!
Try it ! It's worth the money.
Also, call these guys if you have questions man. I do, and there more than helpful and very knowledgeable, they love talking supplements! They do good business. Quick on deliveries. Always sent out within 24hrs of ordering so far.
Check em out you all.

Seeing results

I have been taking this for about 3 weeks now and have seen weight loss and muscle gain. At 54 I was struggling to lose the unwanted belly fat and since taking this product and working out 4 times per week and eating healthier it all works together well. I have tried several other products with zero results and wasted money. Looking forward to seeing how it helps over several months of use.

Love it!

Could be a little less expensive. Works well though.
