Cutting-Edge Activities



Dendrobium acts as a central nervous system stimulant in addition to being rich in PEA. This combination provides a very smooth energy coupled with powerful mood enhancement capabilities.*



Increases focus, concentration and enhances mood. phenylethylamine increases the process of lipolysis through stimulating the release of catecholamine.*

Caffeine Anhydrous


Has thermogenic properties that aid in the burning of fats. Caffeine in the body leads to increases of epinephrine and norepinephrine. These two hormones signal the body to dissolve fat so that it can be available as an energy source.*



Theobromine is an alkaloid found in chocolate and cocoa, which acts as a mild stimulant and mood enhancer.*

Theacrine (Teacrine®)


Enhances physical energy by causing adenosine- signalling changes similar to caffeine but with longer lasting results. It also acts as a dopamine antagonist which enhances physical energy even further.*

Cayenne Pepper


Increases metabolic rate and boosts the secretion of catecholamines to help burn fat while suppressing appetite. Acts as a bio-igniter to rev-up body temperature via thermogenesis.*

Bitter Orange Extract


Increases lipolysis and metabolic rate to burn up stored and incoming body fat. It also works as a potent appetite suppressant to help tackle tough cravings and diet hunger.*



Aids in decreasing the size of fat cells, improves cholesterol levels, suppresses leptin and lipase (the hormones that help regulate hunger), acts as a thermogenic, and boosts metabolism.*

I got to say that this stuff will get you heated up. Started out taking it in the morning (~4:30am)on day one and two - on day two about 9am I am walking around at work and its kinda cool outside around 45 degrees and I am sweating... I am wondering why I am sweating and then I remember oh yeah dummy you took the SEMTEX this morning! I would mention that you probably should take this with some food on your stomach... My stomach wasn't very happy with me taking this on an empty stomach. I did switch to taking this in the afternoon about 30 minutes before leaving work and heading to the gym which is about a 30 minute ride from work, gave me a good sweat and energy while I worked out but missed the pump I get from my Pre so went back to taking it in the mornings and sweating my butt off while at work. Didn't matter if I was sitting around or really busy turning wrenches, had a good warm feeling all over and decent sweat from sitting still to fully active. Definitely would recommend this product for someone looking to cut. Careful if you are stim sensitive this has 300mg of caffeine and 200mg Theacrine. Add in the Cayenne and piperine and there goes your sweat factor. SEMTEX also helped curb my small cravings I was having around mid morning. I'm down about 8lbs in 3 weeks since starting this along with my diet that I have been on for about 5 months now. Really love the products that Nutrabolics puts out!
