Finally finished my first tub of this stuff. Great product but i dont think i would be buying again. The pumps you get from taking this twice a day are literally insane. The price was also good, at the beginning of the month i was able to get buy one and get one half so a buddy and i just split the difference. The taste wasnt that bad either. For what its worth definitely a great product. Also have to add, great boners from the increased blood flow.

This is a Great Product from GNC. I bought this a while ago for under 40$ and it lasted me a very long time. Typically I added a scoop of this to my preworkout drink when I was no longer getting great pumps from it ordinarily. It gave me Great Pumps! My Muscles Loved this product. My Veins really Bulged out of my body when I took this, and my whole body would flush a little. A great Feeling.

Also its nice to take this before bed to Increase N.O. Levels which also boosts Growth Hormone levels while you sleep.

5 Grams of Micronized Arginine is a Great Dosage for anytime. The taste was Ok, Fruit punch tasted good. This only had 1gram of Carbs in it as well. Nothing else, plain and simple. I recommend you take this on an empty stomach for the best results> an Hour and a half after youve eaten.

Wheteher you want to add this to your preworkout or before bed, or anytime of the day you Want> This Product Delivers! This Gave me good recovery from hitting the gym Hard! Hey This product also gives you a Good Boost in the Bedroom. Gave me a little more energy and Stamina. Your Girlfriend will think your Superman! haha

Awesome product for a fantastic price. It is typically less than 40$ and often times part of GNC bogo sports promotions. It really is the only ingredient you need for an effective pre as the majority of other products use it as their primary. Great pumps, decent taste and lasts whole workout. The unflavored is really rugged, but the punch one is quite tasty.

This is a great product by GNC. most of their products are usually hit or miss so this could of gone either way. but i wanted to add arginine to my stack so i picked this up at GNC for 30$ with my gold card discount. let's get to the review!

Profile: 5000mg of Micronized L-Arginine
1g of Carbohydrates
pretty simple which is always good.


Taste: i got the fruit punch flavor it taste pretty good! alot better than most preworkout products. It mixes extremely well too, i add a scoop to about 8oz of water. they also make an "unflavored" version so you can mix with Gatorade or juice, etc.


Effectiveness: gives me a great Boost of energy in the gym and a decent pump! and zero crash. keep in mind i have a very high tolerance for stimulants. i'll sometimes add it to my Jack3d preworkout drink for that extra Boost. or i'll just mix it with a scoop of Beta Alanine (3.2g). and since its micronized it hits the bloodstream almost instantly! which i love


Value: Hands down one the best values i've ever purchased. 30$ for 80 servings (1 scoop per serving), and 1 scoop is plenty. never had to use 2 scoops and ive been using this product for about a month and a half now


Overall: solid product by GNC. i would definately buy this product again. if i ever run out! and i would definately recomend it to anyone looking to add a Boost to their preworkout shake.

This is my first review so bear with me...I went to GNC and bought the Arginine 5000 tablets. I take four pre workout with my MusclePharm Assault. It adds to the Assault's pumps and gives me a great feeling with my vascularity. The only thing I would change about this product is the price, its a little pricey at GNC but I'm sure you can find it a little cheaper somewhere else. I also don't like that after the first 3 weeks or so you don't really feel the rush of it anymore but the pumps are still there! Overall I think its a good product to stack onto your pre-workout to make it more effective

A bit pricey. Tastes pretty good if you get the fruit punch flavor version. I did not want to try the unflavered version.

-great pumps
- easy digestion
- good clean energy, but not the type you get from a prework out supplement.
- muscles feel solid hours after work out.
- can be mixed with a pre-workout supplement if your low on energy.
-lots of servings.
- great for a creatine free cycle.

first off, never ever buy the unflavored arginine 5000 cause it is like drinknig poison. one and a half scoops of this stuff about 15 minutes before my workout was all i needed for MASSIVE pumps. the pumps were so huge that i literally felt like they were going to burst through my skin. fruit punch tasted really good and it completely dissolved in a glass of water within 5 seconds of stirring. dont expect any increased energy because it doesnt have any stimulants. if you are currently taking a pre-workout, this is a gr8 product to stack it with for crazy huge vein popping pumps at the gym.

my favorite arginine supplement, 5g of arginine per scoop, and 80 servings per container. the powder is like flour so it mixes very well, i've had the fruit punch flavor and it tastes really good. its micronized so it hit's your system faster, and lets your body absorb it easier. it gave me a good pump in the gym and increased my vascularity as well.

i stacked this with Jacked and it gave me good pumps but no energy. the price wasnt bad 20 dollars with gold card at GNC. it got bigger arns when i took this with Jacked. i think it works better when combined with Jacked.

Actually a decent price with gold card. (Usually the GNC prices are too high even with gold card) 80 servings at 5 grams per serving which is good. I found the flavor to be pretty good actually. Ive tried Cheap Supplements version of arginine and it was unbearable. As far as effectiveness it is what you would expect from arginine i guess. Pure arginine for the "NO" factor nothing else, does what it is supposed to I guess. I am a little more than half way through the 80 serving container. I recommend this product for your preworkout if you are also using something else preworkout weather it is creatine, BCAA, caffeine or something like that.
