Another good supplement from this great company. I use this as a weightlifting athlete. I'm an undergrad in Biochem, so here's some limited background and science on the PRODUCT (citrulline) as I understand it: Citrulline is an amino acid that is converted to arginine after ingestion. Arginine is useful for an athlete because it is an essential amino acid that regulates bloodflow and nitric oxide levels (in weightlifting, this equates to more blood flow to muscles, allowing for stronger contractions and a better "pump"). There are oral supplements that are simply just arginine, however, this method is not reliable for increasing arginine levels in the body because they are weakly orally active, meaning that the arginine is not efficiently absorbed by the intestines. However, citrulline is. As a result, taking citrulline and allowing your body to convert it to arginine is more efficient in raising arginine levels in your body, as opposed to supplementing with just arginine. The mechanism is pretty well understood among the scientific community. Personally, I've been using this supplement (from a variety of brands) for over a year and a half now and I would say it definitely does the job. Citrulline is found naturally in a lot of different meat and fish products. However, if you don't eat fish or meat products, or not very much of them, chances are you are going to benefit from a citrulline supplement. As far as the brand goes, I recently began ordering from Bulk Supplements all the time. Their supps are almost always the least expensive and cleanest stuff you can get from any company (clean as in no other ingredients; you only get what you came for. That's how it should be in the whole supplement industry, but often that isn't the case.) Great job, Bulk Supplements. Read more

I tried using a regular teaspoon at first. The taste was very sour. Then, I weighed it out with a food scale and found that I was taking almost twice as much as I wanted to. I wanted 3 grams and I was taking a little less than 6 grams. I wound up using the scale and measuring out 12 grams and adding it to twelve ounces of water. Now, I measure out three ounces of water and add that to a mostly full water glass or add it to a protein shake. It works better for me and is not as sour. I do get some heartburn. It isn't nearly as bad now that I dropped the dosage. I have been taking it for a week now and have not measured the results. I plan to check in a couple of weeks. Read more

I train fasted every morning, and combine my pre-workout with BCAAs with Glutamine to prevent soreness and muscle loss. The fasted training requires that my pre-workout be as devoid as possible of calories. After trying several different pre-workout supplements that met that profile, I found one that I felt worked pretty well and delivered on its promises. It produced a great pump and a smooth energy boost with no jitters or crash. There were two things about it that bothered me a little bit though - the price per dose, and the fact that it included 350mg of caffeine. I tolerate caffeine well, but wanted the option to reduce it or eliminate it for low/no caffeine days, or on days when I can predict that I'll be drinking lots of coffee at work. In an attempt to recreate the formula of my favorite product, but sans-caffeine and at a lower price per dose, I purchased the following Bulk Supplements products from Amazon and combined them in the following amounts: Pure Betatine Anhydrous 250grams package: 1 teaspoon Pure L-Citruline DL Malate 2:1 powder 500 grams package: 1 tablespoon Pure Beta Alanine powder 500grams package: 1 teaspoon *Note that the amounts above are much greater than the recommended amounts on the Bulk Supplements product labels, but are very close to the dosages in the product I was using. The product that I was using also included L-Ornathine, also available from Bulk Supplements brand. I may purchase the 250gram package of that at a later date and add to the cocktail at an amount of just under 1 teaspoon per dose. So far, the experience of my experiment has been positive. Most importantly, I feel the effect of my cocktail is about the same - great pump, no soreness, comparable increase in energy and stamina as opposed to without. When I feel the need for caffeine, I take a single 200mg Caffeine Anhydrous pill that I also bought from Amazon (100 for six dollars). As far as cost goes, the stuff I was using is about two dollars per serving. With the sizes that I purchased and the amounts that I'm using, my blend costs about seventy two cents per serving (less than half). If I were to add the L-Ornithine, the new cost would be just under a dollar a serving (still less than half). The powders dissolve easily in filtered water. In 10-12 oz, my cocktail is about as acidic as strong lemonade and no less palatable. I tried it once without adding the BCAA+G and found that it was drinkable as-is; acidic, but not bitter or fowl-tasting. I tried adding pure stevia leaf extract (without erithrytol or other artificial sweeteners), but without the benefit of a flavor to enhance, that didn't really provide a flavor improvement. Perhaps some lemon extract might have coupled with the sweetener to make a nice blend. I purposely drink my mix before brushing my teeth in the morning, as I felt that drinking it afterward might have caused some sensitivity. Regarding the packaging, I imagine it's very important to keep moisture out. To this end, some might find fault with the locking seal provided on the bags the products are packaged in. They can get fouled by the powder getting in the track during shipping. I simply cleaned the track out by using the thin back end of the cheap metal measuring spoons that I use (from Walmart). I suppose the tip of a keen knife would work also, but at risk of cutting through. The Betatine started to develop a clump or two on top, so I put a silica bag inside to absorb any moisture that I was unintentionally introducing to the bag and haven't found any additional clumps since. I'm providing this same review for all the components of my blend, as I can't honestly review each of them individually, never having tried any of them in isolation. If I add the Ornithine, I'll provide an update. Read more

Taking 6g daily 1 hr before gym, rinse mouth with bicarb afterwards to protect teeth from acidity. Noticed less pain and more stamina during workouts. Works better than beetroot which I have discontinued. Also discontinued creatine because it interferes with creatinine levels in my lab tests. Don't notice any side effects. Will continue to use. Highly recommend. Starts working in about a week. Read more

Yes, Pure L-Citrulline DL-Malate 2:1 is truly effective in "boosting my reserve energy level - When I need it" I highly recommend this specific product. It is a very "clean" - no noticeable side effects - do not feel a buzz, like with a double shot of espresso. Doesn't keep me awake at night - I sense it is very safe! Non-habit forming - No biological urges to take it. No noticeable loss of my normal mode energy and limitations if I miss taking it. BUT, it's like now, I have a "Tiger-In-My-Tank", or a "Turbo-Power" mode switch that automatically shifts ON when I get the notion to push harder physically at a challenge. And the "pushing" is fun, enjoyable, positive - NOT work or grueling or "I can't wait till it is over" thing - 'You know what I mean'. Examples: I ride my road bike to & from work every day - in both directions. I have to climb 2 long hills and 1 short one - been doing it for years - always been sort of grueling - shift down to lowest gear and still my cadence always slowed down. Since last 6 months, taking just 2/3 teaspoon in 6 oz water about 45 - 60 min before riding, I now amazingly have this "reserve power - about 20% more to power up the hills feeling super and strong -with stamina!!! In that way L-Citrulline DL-Malate 2:1 is rather Magical - Strong energy boost only when you ask for it! This extra inner capacity to push seems to last a few hours, because without taking additional dose, I find it easier to do 10-12 more Push-ups during the day at work break - and say 20-30 seconds more prone Plank for Abs toning than this supplement. I detect no extra increases in heart rate or hyperactivity or any other biological reaction. Psychologically though - I feel many, many years younger, and after my workout - super healthy. I repeat 2/3 tsp 45-60 min before riding home. Same super-feeling during the ride up hills and when I get home. But like I said - I don't feel any different after taking the dose - this is until I start a physical activity where I can choose to push. There is a subtle feeling of "super wellness" I suppose where a little voice in my head says, "Go for it - Climb that hill fast - You've got the Power! Now I enjoy those little challenges where I can "enjoy pushing my body harder - and feel confident and safe about it". The contents are fine snow-white pure crystals - I just stir in plain water a few seconds - Pleasingly mild citrus taste. (Note: Earlier this year I first tried "L-Citrulline without the Malate 2:1 formula" - and I did not experience any boost in energy or really anything - no reaction. whatsoever.) After more research I chose the Malate 2:1 formula as the fit seemed to match better what I was looking for. Hoping all of you have similar experiences of there being a "Tiger-In-Your-Tank", Tom in Carlsbad, CA Read more
