Moderate performance benefit, good pumps. Nothing insane, but definitely a slight and welcome gain. Sour taste from the malic acid, which I personally enjoy, especially mixed with gatorade or something of the like.

This product provides a nice taste and mixability and a good pump. My pre-workouts I have used before always has this in small amounts and getting a bag of citrulline really improved my pumps (veiny indeed). I would recommend getting this when there is a discount as the full price is a bit high for my liking. Luckily, the site always has deals that you can stack for this product. I like to take this 30 minutes before a workout as that has helped me feel the best pumps mid workout. If you want more discounts, you can use SUNNYdashR2AO, replace dash with the - key to get 45% off your first order!

Based on some articles I read I decided to try using this to make some homemade pre-workouts. Overall I've been really pleased with the effects of this compared to pre-workouts I've tried that contain citrulline. Because of the malate it does have a sour/bitter flavor so I've tried to find a medium to make it more palatable. So far I've mixed it with a couple BCAAs, gummy fish, snocone, and cold brew coffee, and it has helped tremendously. I can also throw it in a juice base, like grape, to cut down on the bitter/sour nature. It does mix well, and works really well, so overall I'm pleased with the product. Everyone's taste is different, so it may be more/less bitter/sour to others, but it does feel like it works well.

I really like that I can buy this as a stand alone product. Great price as usual. Doesn't mix great and it is extremely bitter by itself (but that's just the nature of the product, not this particular brand).

Cheapest citruline malate I could find on the market. Works very well. I am more vascular when taking it. I recommend minimum 2 suggested “servings”. Highly recommend this product.

Water and some kind of sweetener like mio to help with tatse.

I mix this with my preworkout every day when I go to the gym and I love the pump it gives me. Would definitely recommend to friends. 

Good product. Good taste with an extra pump. Increased my vascularity. Highly recommend If you need a massive pump while you workout.

Cheap and effective if you can handle the bitter taste (i like it personally). I always use 6g of the stuff and it gives you more of a pump than anything else, a necessity for a good preworkout.

So far so good. Been taking for about a week. I mix with BCAAs about an hour before my lift. Taste is kinda bitter alone but mixed with the peach lemonade bcaa powder it’s great. Get a great pump while lifting. Will definitely keep buying.

I really like the tart flavor. Most days I run 1000-2000 stairs in the morning and then do a workout in the evening. I use this product for both. Does it help? So hard to say really but it tastes good and I make the assumption it helps and at 60, I will take any little advantage I can get.
