TRI AMINO ACID BLEND: Gain's in Bulk's Argi-Pump contains high amounts of a very pure form of arginine to work within the body’s natural pathway to promote nitric oxide levels. However, as we age, this pathway becomes harder for the body to use if the amino acids l-citrulline and l-ornithine aren't present. This is why we've combined all three amino acids into our Argi-Pump formula.
PROMOTES HEALTHY FLOW TO ALL MUSCLES: Promoting nitric oxide levels in the body can help with healthy flow to all muscles. Supplementing with our l arginine supplement can support you in promoting your nitric oxide levels, leading to better vascularity during your workout.
MASSIVE GAINS: This arginine supplement is research-backed to promote larger and fuller muscles every time you lift. Argi-Pump naturally promotes growth, so you can see massive gains.
HOW TO TAKE: Take 2-4 capsules pre workout for effective pump. Take 2-4 capsules before bed to naturally promote muscle growth and gain.
THIRD-PARTY TESTED: All Gains in Bulk products are third party tested to ensure purity. To prove our commitment, we provide Certificates of Analysis with every single Argi-Pump delivered. This certificate shows the exact measured amounts of each component within the formula. We aren’t interested in hiding our formulas behind closed doors. We believe that you deserve quality vitamins and supplements and full transparency.

Big pump in gym
This product is the best supplement to add to caffeine and creatine for an incredible workout. I’ve been taking it for 3 years.

when all else failed
This is probably under my husband’s name (comma button inop). This is his wife Ava. All summer long; he has been going down hill. We do things homeopathically; but Dave won’t stick to the mostly leafy-greens diet that the Dr. is proscribing. All of his joints are swollen. He is freezing cold in the height of summer in the desert. It’s almost like he developed rheumatoid arthritis all at once. We know that his liver isn’t processing things right. I did some research on the Urea Cycle and found the three main amino acids that control the elimination of urea. This is the ONLY product I could find with all three aminos. THE FIRST NIGHT he took 2 a couple of hours before going to bed. He was sitting on the edge of the bed; undressed; a couple of hours later and said “I’m hot.” To me; that was a miracle. It has only been 3 days now; but his voice is stronger; his demeanor is more positive and he is complaining a lot less than he has in months about pain. I am hopeful when I had all but given up hope for his life. He takes 2 in the morning and 2 prior to going to bed.Thank you for the encouragement. Even though the product is used for something else entirely; I am very grateful for just the little improvement I have seen so far in my husband.It seems that we are trying to do some body RE-building…. 🙂 <3 (Interesting...the comma doesn't work; but the "less than" symbol does...same button...didn't know....)

Makes a difference
I have consistently taken this product and I see gains in muscle. I have added three to four pounds of muscle. I like taking this before my workout. I would recommend it.

Was worth buying: reordered.
Works good. The lost Hair (due to aging) on my bare arms grew back.Manhood is more alive — firm, but no elargement.Also, my weak voice (due to aging) became full again.Worth trying? Yes, I have joined the subscription auto-mail program.Age spots faded from my arms and back of hand. Arms seem to have more muscle tone & definition.

Not the same as the picture
I’m dissapointed in the fact that the picture of the product shows that the ingredients have over 3000mg and I got the bottle and it only has 2550mg that is literally false advertisementSo idk if it’s Amazon’s fault or the gains brand either way it’s false advertisement and that should be taken extremely serious . So very bad in my opinion
