  Noticeable effects

  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.

  Totally worth it

  One teaspoon works wonders for boosting nitric oxide. Almost tasteless. Cloudy.

  Great Product and a Tip For Fixing Bag Zippers That Won't Seal

  ---------------------------------------------------------------------------------------------------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 PillThis 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.

  This is an awesome supplement, and buying in bulk like this is the most practical.

  I have used L-Citrulline for years, from different brands and different combinations. I get this because its easier and dramatically more cost-effective buying just the bulk powder and mixing it into your drink of choice. It also doesn't taste nearly as bad as a lot of other supplement powders I've tried, so that's a nice bonus.I have used this company's products before, and the quality has always been solid and this product here is no different. It is exactly as described and that's it, it's a bulk bag of pure L-Citrulline powder, NOT L-Citrulline DL-Malate, which is a mix that is often used in lieu of pure L-Citrulline that people sometimes overlook. This is the good stuff if you're looking to increase your vascularity, muscle endurance, and increase bodily blood flow as well, so whether its increased lifts in the gym, better performance in the bedroom, or just improved cardiovascular health, this stuff works. Not gonna lie, it's gotta be one of my fav supplements I have tried and continue to take.
