Product Information

Description

ADVANCED, TRIPLE-SOURCED L-ARGININE
L-Arginine SX-7® Black Onyx™ delivers a powerful pump-inducing matrix that quickly disperses into your bloodstream when you need it most! This advanced arginine matrix supplies three forms of L-arginine, the critical precursor to nitric oxide. Plus, it’s sugar free and non-stimulant so it can be stacked with any other SX-7® Black Onyx™ product for your best workouts.*

Powerful Nitric Oxide Precursor
MuscleTech® researchers developed the most advanced, ultra-pure, triple-sourced L-arginine formula ever. L-Arginine SX-7® Black Onyx™ delivers 6,000mg of L-arginine, including ultra-pure micronized L-arginine for rapid uptake and dispersal in your body. Flooding your body with this powerful nitric oxide precursor primes you for extreme pumps and enhanced blood flow and nutrient delivery.*

Scientifically Superior Formula
When you train, your body releases calcium in the endothelial cells that line your blood vessels. This causes the enzyme nitric oxide synthase to create nitric oxide from available L-arginine. As the nitric oxide leaves the endothelial cells, the blood vessels relax, causing vasodilation. By supplying a massive dose of L-arginine to your body, L-Arginine SX-7® Black Onyx™ helps trigger extreme nitric oxide production for superior vasodilation effects and massive musle pumps.*

I'll be buying it again.
First off the taste is good.
I try to take it 15 - 20 minutes before a workout to get it in. But, even when I've used it during the workout, I can feel it kick in giving me that added boost to get through it.
Like I said, I'll be buying it again.

Awesome1
This stuff is great! Gives me a great pump at the gym and I typically stay a bit longer on the mornings I take it. I go at 5am, so I take it around 4:30am to give it time to kick in. Overall, awesome product.

what you need
This is an amino acid primarily found in red meat. so If you are a plant based protien consumer or dont eat meat, then you may need this product to get those essential aminos you are not getting. Muscletech is top of the line stuff and black onyx is really pure. overall very happy

Must Try!
I usually don't use anything that is sugar-free or non-stimulant based because I prefer them. But this one is a staple in my supplement pile!

Love it!
This is great! L-Arginine can be used anytime since it doesn't have any stimulants and is sugar free. I have combined this with my Hydroxycut Black Onyx as a preworkout and I love the combination. When I use this I feel a great pump during every workout but can even use it before bed since it doesn't have any crazy energy ingredients in there. I'm really happy I received this as a free sample from MuscleTech.
