Before I made the purchase I asked A.I to evaluate this product. What I got was that this seller and this product are highly rated for quality and price. The jury is still out for the benefit I'm seeking as that could take 4-6 weeks.

    • Great for the gym and bedroom, no joke
Size: 2.21 Pound (Pack of 1)
This stuff definitely works as a vasodilator and is the must-have foundation of any pre-workout in my opinion. I typically take it first thing in the morning whether or not I'm working out and believe it has significant effects on recovery from exercise and gets you kick-started to get on with your day. Then before exercise, I almost always take the same 3 gram dose. I use 3g on an empty stomach mixed in a custom pre-workout, or with the occasional pre-made PWO that I try. Most pre-workouts have an insignificant amount of this if any, so I "stack" it with almost everything I buy, and prefer to make my own pre-workout from scratch using this, agmatine, and beta alanine as a base. 3g truly is the effective dose for most people (I weigh 217) and typically to get that amount from a pre-workout mix, you'll have to consume an undesirable number of scoops, including artificial colors, sucralose, and excessive stimulants. And men, even if you have no problems whatsoever "downstairs," it has a noticeable effect on sexual performance, period, it is noticeable for sure and has been studied in comparison to Viagra with encouraging results. The simplest thing a man will notice 30 minutes after taking 3 grams of this is that when you urinate, your stream is huge and powerful because your tissue is significantly plumped up with blood, even in a flaccid state. Sensitivity is increased but control also seems to increase, possibly because pelvic floor and basically all other muscles are full of blood and performing optimally. I am confident this effect would be beneficial to women as well, whether due to their use of the product to increase their own blood flow, or due to their male partner's use. As mentioned, it's extremely unlikely that your pre-workout mix of choice has an effective 3g dose of citrulline in a reasonable number of scoops. This is better than arginine because it's more bioavailable, and more rapidly assimilated via the kidneys, so you end up with a more significant amount of arginine in your tissues, and experience better vasodilation. Beyond citrulline (3g), agmatine (1-2g), beta-alanine (2-3g) and creatine (5g), I use caffeine and occasionally other stimulants in my pre-workout; my main combinations are: 1. (caffeine or caffeine citrate or teacrine) + hordenine + PEA 2. (caffeine or caffeine citrate or teacrine) + higenamine 3. (caffeine or caffeine citrate or teacrine) + yohimbine (this causes intense vasodilation and pounding heart rate, best for interval training, essential in an intermittent fasted state in the AM with BCAAs, maybe 2 times a week, tops under exercise, watch your heart rate and back off for 2-3 minutes when it tops out) Your results may vary, I am not your doctor, don't kill yourself if you're out of shape and/or have family history of or existing high blood pressure, etc...I provide no stimulant dosing information because it's a personal risk you take and I'm not as confident throwing numbers around as I am for amino acids and creatine, but here's my point in bringing it up: L-citrulline seems to really take the negative edge off of stimulants in a pre-workout supplement, especially those that can raise blood pressure (not caffeine alone) because it's offsetting the vasoconstriction caused by things like PEA, hordenine, or higenamine. Back to the bedroom -- again, I am not your doctor, but if you are sufficiently healthy and acclimated to an effective dose of yohimbine and/or rauwolscine (I typically consume 3-6 mg of yohimbine and 0.5-1mg of rauwolscine using a supplement not available on Amazon from AllMax) and combine that with L-citrulline, agmatine, and beta alanine, 30 minutes before sex, you will probably be very impressed. ... show more

Bulk Supplements is my go to for quality and reliable products. But, buyer beware, the supplement industry is not regulated by the USFDA thus, check out your suppliers before you buy and if it looks shady don't buy.

    • Noticeable effects
Size: 8.81 Ounce (Pack of 1)
I received my order quickly and they even sent me a free sample offer of other products of my choice. I started taking it because L-Arginine really can upset your stomach and liver in supplement form. However, you can take L-citrulline which then converts to L-arginine directly in the bloodstream. I can take larger doses with absolutely no side-effects. I took it for better heart health, protein synthesis and stamina while doing cardio and weight lifting. On the third or fourth day of taking it, I noticed my breathing was much easier. It was almost like I was getting more oxygen. I assume this is from the blood vessel dilation. I was also able to do cardio with more intensity without getting winded. I did not notice a boost while doing weights but the studies imply that it lets you do weights longer. I did not test this theory. Some sites promote L-citrulline for erectile disfunction. I do not have that but I did notice a difference in that area. I am not saying anything got bigger or harder but my "walking around" size seemed greatly affected. I assume that is from the increased blood flow as well. If you did have erectile dysfunction, I think it may have benefits. The taste is not horrible or good. It is a little metallic-ish. Just mix it with a drink and you will be fine. It takes about 10 seconds to dissolve when stirring. The packaging is good but I had an issue with it resealing well. I just started using a clip on the top instead. It could just be a one time thing. Anywho... I will probably buy this again and from Bulk Supplements since I actually had noticeable positive effects and no negative effects when taking the product. ... show more

    • Great Product and a Tip For Fixing Bag Zippers That Won't Seal
Size: 1.1 Pound (Pack of 1)
--------------------------------------------------------------------------------------------------- HOW TO FIX ISSUES WITH THE BAG NOT SEALING PROPERLY --------------------------------------------------------------------------------------------------- First off, let me start with this little tip that will save you from the potential headache of the zipper on the bag not sealing properly. When the bags are filled, they are not sealed off by using the zipper, and instead the top of the bag is sealed instead. This leads to the product moving around in the bag during shipping and handling, which ultimately leads to it getting in the zipper tracks. The simple solution is once you open up the bag for the first time, take a toothpick and use the tip to clean out the inside of the tracks, as well as the outside of the single track. Once you do this, you will find that it is much easier to get the zipper to work, and that it provides a great seal. ----------------------- Product Review ----------------------- Overall, I am extremely satisfied with this product. The quality seems on par or higher than other brands that I have tried, and you simply cannot beat the price, or the fact that there are zero fillers. I have been using the product as a part of my Pre-Workout stack for its health benefits, as can be found on examine.com: [...] ■ Orange Juice - 8 oz ★ Creatine HCL - 4000 mg ★ L-Arginine - 1500 mg ★ L-Citrulline - 3000 mg ★ D-Aspartic Acid - 3500 mg ★ DHEA - 50 mg ★ Spirulina - 4500 mg ● Indole-3-Carbinol - 1 Pill ● Super B Complex - 1 Pill ● Vitamin D3 - 1 Pill ● Caffeine - 200 mg - 1 Pill This product has made a huge difference in my workouts since I seem to recover quicker, and I don't experience the soreness that I used to. With the added health benefits, plus the amazing pump that I get when combining this with L-Arginine, it is a for sure winner in my book. ... show more
