MRI NO2 Black Nitric Oxide Supplement for Pump, Muscle Growth, Vascularity & Energy - Powerful Stim-Free Pre-Workout with Citrulline (30 Servings) (Black Razzy Ripped)

Great taste. Awesome balance. Only concern it was clumpy.

I received the NO2 BLACK but was exposed to moisture and is clumped and hard. This item was also sealed but the white cover on the container was half open. I want to order a new one but I already spent $54 on this one that is no good

MRI products are the only ones I have used for years.

The product arrives as if it has moisture penetration. I have purchased twice and both have come the same…chunky. I’m not sure if that’s how it is supposed to come, but the product is not returnable or refundable.It does work, though, so that’s why I have it four stars.

Works great - but I hate this tiny new packaging - hard to get me hand into this little package and my hand gets covered in the product - the lower the amount in the package the harder to get out. Make the package bigger or go back to the round tub.

I don't know what it is, it can't be the lack of citrolien malate in it -- 2 scoops nets you more than an adequate dose -- but whatever it is this just falls flat in every area.A total waste of money when you have Total War and nitro surge both in the same market space.The stats of all 3 are comparable, but this product just doesn't do it for me. I've tried everything under the sun chasing the pump of the late 90's to mid 2000's before everything became overly regulated and the FDA put training wheels on what is "best" for you.Well, those days aren't coming back and products like this don't help. Even the two above mentioned are less than desirable but due to regulations they have to suffice.To add to all of this: this product came with count them 3 giant moisture packets that did absolutely nothing to prevent clumping and hardening of the product.I had to take a knife and dice up the boulders. Totally unacceptable at this level for what you're paying.I get it, if you're not clumping you're not pumping -- but you're not pumping when the products are gimped. I don't think anyone today so didn't live through the 90's even knows what a real pump is.Long story short:Pass.

The powder is so clumpy on arrival, and that's with them including 3 packs of dessicant. This stuff doesn't mix, tastes disgusting and even with a double dose I can barely notice a pump. Will never ever buy again. Worst preworkout I think I've ever had.

Very effective product!
