Jacked FactoryEssentials Nitric Oxide Booster - Patented Bonded L-Arginine Silicate 1500mg Pre Workout Supplement for Muscle Growth, Pumps, Vascularity and Energy - 90 Veggie Pills

I have been using this product for about two weeks and I noticed better pumps and more endurance at the gym. Pills are not too big and easy to swallow and there is no bad taste.

Super stoked Jacked Factory sells Nitrosigine by itself in the recommended dosage required for the effects stated in the studies. Other company’s combine Nitrosigine with other stuff and that’s not what I was looking for. Glad I found this product! I have not used this yet as I am waiting for my current nitric oxide booster to be gone but from the research I’ve done on Nitrosigine I’m hoping this provides awesome results! I will update this review after I’ve tried it.Update:After taking this product for a week I can say it is absolutely amazing! The pump I get is unreal compared to other nitric oxide boosters and the vascularity in my veins is amazing it really makes them pop! Great vasodilator and nitric oxide booster! This is definitely my new pre workout supplement! Thanks jacked factory!

I started taking these while backpacking for a blood flow and endurance boost. I put them on a shelf bc I didn’t notice anything substantial. After pandemic I resumed weight training at a gym YEE HA! after over a year ....that’s where these shine. Heavy weights gives a noticeable pump in arms / shoulders legs etc. I’ve always been a good responder to AAKG Citrulline etc while weight lifting. So my advice is use it while weight training and don’t expect a miracle while backpacking/hiking or doing endurance activities. It pumps you up and works synergistically with a good pre workout.

Seems good, but i need to take it awhile to know. The ingredients are the ones that are supposed to be good.

This is a great way to really feel like a kid again. At 67 years of age I needed the extra boost every day, and especially on days when I mow the grass. The extra strength is noticed when that thermometer climbs into the upper 80's and low90's and the dew points are into the upper 60's. My mower requires me to push it and has a bagger. I have to cut 3 days in a row at 2 to 2-1/2 hours each time. I can really feel the difference when I have to push it uphill with a 35 pound load of grass in the bagger. I don't lift weights but this is not only for weight lifters and can be utilized by everyone that leads and active lifestyle. One other thing that I have noticed is it will increase the blood flow to all extremities!

Started on this product from recommendations from other bodybuilders in my gym. I use a great preworkout and they recommended to take it as a stand alone, as they said it gives great pumps, focus and workout power. Unfortunately I didnt get any of them. I will stack it with my preworkout tomorrow and see if there is any boost in energy, pumps or focus. If I see a difference after that I could give it more stars, but not sold on the product yet.

Product is a solid product. This particular form of arginine, nitrosigine, is imo superior. There are some studies and documentation to back this up along with my own personal experience. An odd thing had happened though, my last two bottles I ended up with two as my last serving? So I either got two extra or one short. I will definitely be looking at this more closely on this bottle. Clearly I like the product as I continue to buy and recommend it pre workout. Hopefully the other issue is a snafu that has been resolved. Or it was me!! Ha!

My body wasn’ making enough L - Argintine, using this to supplement what I’m missing
