Excellent Pre-Workout Ingredient
Size: 2.2 Pound (Pack of 1)
Easily one of the best (if not the best) pre-workout ingredient you can buy. Don't need all those fancy and expensive pre-workouts if you combine this with some caffeine. 3g is too low of a serving size btw. I go 9g.

Pleasantly Surprised
Size: 2.2 Pound (Pack of 1)
As a previous Bulk Supplements customer I was sent a sample of the 100 gram L-Citrulline powder in exchange for an honest review. I'll start by saying I didn't have high hopes for the product but in the end I was pleasantly surprised. I'm one of the few lucky men that have been diagnosed with Fibromyalgia. I have severe pain from trigger points in my neck and upper back/shoulders. I've often wondered if part of my problem lies in not enough oxygen getting to the "trigger points". Since L-Citrulline is supposed to lead to an increase in Nitric Oxide production which dilates blood vessels allowing more blood and oxygen to get to the muscles I figured why not give it a try. After about four days of taking a teaspoon in the morning and one at night (the stuff dissolves in water and has very little taste), I woke up one morning and there wasn't any pain. For me this is huge because I have been in pretty much constant pain for 8 years. It has been a couple of weeks now and the pain has returned, but it is not nearly as intense as before. As an added benefit, it has affected other areas on an old man that didn't want to work properly anymore ;). I ended up purchasing a 1kg bag and I'm quite happy with the results. ... show more

Natural vasodilator

Mix it with water and creatine before my gym workout. Tastes good not too bitter and helps give me a stronger workout. It really is a smooth working vasodilator.

Noticeable effects
Size: 8.8 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
