It tastes awful, but it works. I respect the Genius Brand, each product I have tried has lived up to my expectations. I had never used L-arginine but decide to give it a try after hearing about "the pump" it provides and reading things like this: "L-arginine is a precursor for nitric oxide, L-arginine promotes endurance and conditioning. When nitric oxide is released, it expands the blood vessels by relaxing the muscles of their walls. The result is lowered blood pressure and increases blood flow to the muscles during your workout." I am new to lifting, a novice really but I have found Genius L-arginine to be a good addition to my training, muscle feel harder and recovery seems quicker. I like to mix 1 scoop Genius L-arginine with 1 Genius BCAA, and 2 scoops of Genius Pre Workout. Read more

I’ve been using this product for about a month now, with every workout. I add it to the GENIUS PRE and take it about 15 minutes before my workout. Combined with PRE and GENIUS BCAA’s, I’ve had great results over the last month. Adding L-Arginine to PRE has helped with blood flow and you can definitely feel/see the pump! And if you like to see your veins pop during a workout, this one helps do just that. Like the other GENIUS products, this has a total transparent label with nothing hidden. Pretty good stuff that is worth trying out with your next workout. There are also articles out there linking L-Arginine to helping prevent migraine headaches (check WebMD too). I was diagnosed with clusterheadaches about two years ago and also get migraines. I’ve seen doctors and specialists but they can’t determine what the cause is (i never had any issues with headaches until I was 38yrs old). I takena prescribed medication daily but even then I would still get migraines and/or cluster headaches, 2 minimum per month. I’ve changed my diet and now know some of the triggers (lack of sleep, cigarette smoke, dehydration, anxiety to name a few) that can set a migraine or cluster off. But since using L-Arginine, I’ve only had minimal issues with headaches, maybe two or three minor headaches during this time. No clusters. No migraines. No ringing in my ears or seeing sparkles in my eyes. I don’t know if it’s the L-Arginine by itself or more likely a combination of what I am doing but I’ll continue to use this product due to it helping manage my headaches. Read more

I will fully admit, this product tastes pretty rough, HOWEVER, you're giving up the toxic fillers, cancer causing color additives, and brain choking oxidants to receive and incredibly effective product. I got away from the infamous pre-workouts after years of abuse and realizing how dangerous all of them are, especially on long term health. My goal was to find the purest, base ingredient that would provide the energy boost needed (especially for those of us whom hit the gym or trails early) and this is by far the most incredible I've ever tried! I literally get rich and continuous energy supply with a moderate "pump". If you want a natural state product that doesn't have terrifying additives and coloring, this is it, trust me. Read more

Hey all - just wanted to share my current results with L-arginine! I know the product is geared towards men mostly (it only mentions men's health on the Genius Brand website not women's), HOWEVER I was reading about it and decided to give it a try because I saw studies that show a correlation between this supplement and healthy blood pressure, as well as reducing migraine pain. I have naturally high bp (thanks dad) and used to suffer from chronic migraines. WELL I take a scoop of this every day with my pre and I have been mostly migraine free. When I did start to feel one coming on, I took a scoop on some juice and very quickly felt the pain begin to go away. Halfway through the day I took another and I was completely back to my normal, pain free self 👌 with NO rx or OTC meds needed, which is amazing for me! I usually take some heavy duty rx meds, but even they don't work sometimes and I can have a full blown migraine for 2-4 days straight. I would definitely recommend giving this a try if you get migraines/headaches. I will try to come back and update when I've been taking this longer with my results for my blood pressure. It is also beneficial for both men and women when it comes to performance outside of the gym, and I can attest to that as well 😉 a medication I started taking in the last few months has really killed my mojo and I've noticed a difference since starting this. ALSO I like the taste! Everyone told me to be careful because it tastes bad but I like it. It tastes like real lemon in water. Adding a scoop with my pre cuts the sweetness which I like, but I can also just add it to water and I can drink that just fine. If you don't like lemon, mix it in some juice and you won't even notice it. I prefer tart/bitter things so I really like the taste. (: Just an extra note - this powder makes more of a suspension, not a solution. It doesn't really dissolve in a liquid, so just make sure you stir/shake before you take a drink so it gets evenly distributed and you don't end up with a bunch on the bottom of your cup. This product came BEFORE the estimated delivery window which was also nice. Anyway hope this helps someone! Read more

You're getting a quality product with Genius L-Arginine. This is a versatile supplement that can be taken before a workout as well as before bed. Some of the great benefits you'll get pre-workout include: increased nitric oxide production (better blood flow = better pumps), increased HGH release during sleep, increased vascularity, improved sexual health. Absolutely love this product. You should be aware that L-Arginine is basic, which means it should be mixed with something acidic to offset any taste issues. You can do a few of things: Mix 1 scoop of L-arginine with 4-6oz orange juice. Mix 1 scoop of L-arginine with 4-6oz grape juice; offset taste with lemon juice. Mix 1 scoop of L-arginine with 1 scoop Genius BCAAs and 2 scoops Genius Pre. Mix 1 scoop of L-arginine in anywhere between 4-6 oz of water. I stir a few times, letting it settle each time before stirring again. Then I'll add anywhere between 7-9 Tbsp of pure lemon juice (you can see the difference in how much is in the cup before and after). Depending on my mood, I'll add either 1tsp of sugar or stevia (I only had sugar on hand here). Tastes like a grapefruit drink and I really enjoy it. If I'm feeling really dangerous, I'll add some apple cider vinegar. Great sleep aid and detoxifier. Genius L-Arginine is well worth the price. Excellent for stacking with Genius Pre for an excellent workout session! Read more

It is HORRIBLE! It’s not even in powder form but rock solid. You can’t consume it, hardly dissolves in water…I never seen anything this bad. Read more
