Hard Rhino Agmatine Sulfate Powder, 125 Grams (4.4 Oz), Unflavored, Lab-Tested, Scoop Included

I absolutely love this product. The first time I tried agmatine sulfate, it was from RSP nutrition. It came in a really small container and only lasted a few weeks. When I found this product, I rushed to order it, as the price was great and it had excellent reviews. Needless to say, I was quite impressed. This stuff, in my opinion, is more potent than the RSP product. I take it before every workout, even if I don't stack it with a pre-workout. I experience an incredible pump and crazy mental focus during my workouts. I even take it on off days because it helps me focus on my schoolwork (engineering school is no joke.) I even got my parents hooked on this product! I will definitely be repurchasing this product when I run out (which won't be soon, as you get a ton of product, and it's very potent).I do have one thing to add. The flavor is quite bitter. Some people mix it with juice, etc. What I would say to do, since you only need such a small amount, is to mix it with just a couple ounces of water to dissolve it, chug it, and it's done. Then just reap the benefits!

Review of the seller: I found no issue with the seller. The Agmatine sulfate was delivered promptly without clumping or a bad smell as noted in some other reviews. My rating is strictly for the product itself.Review of the product: Despite the good reviews/initial study results, this product provided me with no pump during resistance training. However, if the lack of a pump or any positive physiological response was the only fault, I would have given the product a slightly better rating. With that said, it is the severe stomach pain and gastrointestinal issues (read: gas and severe diarrhea) that push my rating to 1 star. While these side effects seems to be rare, they are documented in the few existing studies and by other consumers. I've never had this reaction to any other supplement and I've taken almost every amino acid/amino acid metabolite out there. My assumption is that the sulfate salt component is at the root of the GI issues as these side effects can appear in some when eating eggs (which also contain a relatively large amount sulfur), albeit to a lesser degree.

Good quality stuff. Wish it came with a scoop because I had no way of measuring my dose accurately as I don't have an accurate scale (I have a food scale which is used for grams, kilograms) nor do I have a 1/3rd tsp. measuring device.. I ended up taking WAY too much and going through the whole bag in less than a week. I didn't really experience any side-effects, so I think the safety-profile is quite good. I will probably purchase again. Would recommend. Next time I will err on the side of caution and use a heaping 1/4 tsp. and put it into gel caps.

Best deal I could find anywhere. Also seems to work just as well as more expensive products.The taste seems to be better than my previous brand, but its hard to tell since they both have barely has any taste at all.Looking forward to other great deals from Hard Rhino.

I have tried a few different agmatine products. This one seems to work as well as the others. It has no sulfur smell to it. My primary gripe (and star reduction) is the product arrived very clumped up. A simple desiccant packet in the package would help this tremendously.

For some reason, this is not as potent as the capsuled variety (different brand) that I had previously. I can take the loose powder in large doses very easily, but it just makes my breathing labored if I go above 3 grams or so. I could take 3g worth of the other brand's encapsulated variety and get terrific pumps and amazing, deep sleep. For some reason, this powder does neither... very limited pumps (maybe a placebo effect) and if I upped the doseage, I had sort of breathing difficulty for about 10 minutes. The capsules also had a faint sulphur smell (which they should). My pouch of Agmatine powder is scentless... not sulphur smell. I have had good experiences with some of the Hard Rhino supplements in the past - their Beta Alanine is great stuff, but this one makes me wonder if it is what it claims to be... or if they're cutting it with flour or something. I like Agmatine, but this product has been an entirely different experience from the other capsuled brand I used... and not in a good way.

I add a half teaspoon of this with my Prodigy Pre-Workout for enhanced mood and feelings of well being and it really works because I feel great and energized every day! Google agmatine to find out all it's benefits both in and out of the gym.

Have purchased bulk agmatine before from other brands and vendors. This agmatine mixes and performs the same. However upon opening the bag the first time, it was very hard and in one big clump. Every time I open it I have to chip away at it with a spoon to get the right sized pebble to add to my pre-workout drink.
