This product is one of the few great one's. I've used many Muscletech products over the years and by far this is the greatest, NOx9 has incresced my size and training, I can lift longer and more often. This is great stuff, i ALMOST feel Godly.(but I know my limits) And I have yet 2 have any side-effects.....you know besides POWER!!!

I frequent GNC quite often and noticed a bottle of MuscleTech naNOx9 on sale so I purchased it as I like to use nitric oxide enhancers because I have a hard time getting a really good pump. My form is perfect, I use proper weight, reps intense, I even hit the negative, and I also run two miles before I lift to get the blood pumping. After one use of naNOx9 I went to Jiu-Jitsu and just from the burpee warmup at start of class my arms and chest were gigantic. I looked like I was on steroids. Make no mistake, this stuff works and use the stabilization pod provided because the pills will burst (decompose) within 9 secs if you get moisture on them when bringing them to the gym, it happened to me. As for the rashes I've been reading about, no rash experienced. Burning, only in my muscles but it's a slight heating sensation which doesn't last for more than 1 set. The product does makes me feel a little anxious or slightly light-headed after taking it. However, reading about the guy with the head pressure is rather frightening but I'll bet he took too much of a dosage. Never ever take the recommended dosage, ever. I'm a solid 185 and I take only two pills before a work out, 4 total daily against their 8 total daily for up to 200lbs. I'm now going to reduce my intake to two pills a day.

I've been using this product for about 6 weeks. I rarely take a full days dosage just because I find it hard to do cardio when taking this, even high rep exercises and super sets. It just seems to get my heart rate and body heat way up. If you run often like me, don't take this before a run. My run times have got worse, but not much worse than before, but for sure I've been getting stronger and I look more jacked. Bottom line, if you're a bodybuilder, this may be good for you, but if you cross-train for sports endurance like myself, I would not recommend it.

I'm writing this review on the same day I was released from the hospital cause I have to get this out not. I've been using this product for about 1wk and the results had been really good in the gym. My Reps were increasing and my size were no doubt increasing. But the Side Effects are Very Serious! First of All, the first time I take this product my body felt like it was in flames and I was itching all over my body so I had to soak in the tub immediately to get some relief. Fast Foward to a wk later I have this terrible eposide of heavy pressure on the brain! I mean, this literally woke me up out of my sleep at 2:00am and I didn't go back to sleep! in fact I went to the emergency room to see what was going on! Don't know why but I didn't tell them I was taking naNOx9 b/c I thought it sinunitus. The Dr. actually thought I had a nerve issue in my brain b/c of the way the pressure would move around in my head. He recommended I go to a Neurologist later but before doing that I went to my reg. Dr., which she had me do a CAT Scan right away, Thank God, the results came back negative. Well, before I leave my Dr's office they give me a shot in the "buttocks" to help relieve the pressure. When that Nurse stuck me with that needle my body started leaking blood like you wouldn't believe at the injection site! I was leaking so much blood that the nurse ran into the other room to grab the doc. they were both shocked! As was I! That's when I told them what I had been taking. They scorned me! They told me never to take anything over the counter like this again! This product apparently expolde your veins so much that if you ever hurt yourself or cut yourself in anyway, you could possible bleed out! I'm done taking any Nitric Oxide enhancement product forever! What ever I can't attain naturally in the gym then it wasn't meant to be. So please take this product at your own risk!! And I'm sure we havn't heard the last of the side effects from this product! I have to give this product 3 Stars cause it did give results in the gym but the side effects will be the downfall of NaNOx9

I like naNO X9. Ive been using it for a few weeks now and the results are undeniable. However, like many here, I too have had the rash thing come up. It seems it happens most when you've not eaten yet for the day or not loaded up with water in your system. Its very uncomfortable and very noticeable as my skin turns extremely red at the joints, neck and even my nose. Despite that, I will continue to use it because it works. No other nitrous I've tried so far works as well. When I'm done with this bottle I might try the Nitrix Black that everyone keeps talking about, but for now, this one does the trick. Three stars for the side effects. Other wise great product.

I've been on this stuff for about a year and really like it. I started taking it before I left for the gym and noticed the splotching and itching while working out but now I take it IMMEDIATELY before going into the gym and havn't noticed it yet. It does seem to give me a hot feeling but it's a good burn. I do noticed a big increase in pumps and can go a little longer with it. Very satisfied with it. If you are itching and burning just try to take it right before you walk in the gym and start working out. That should solve the problem.

this NO product is awsome. i started using today at 12:30 i took 2 pills because im only 5'9" and 130 pounds. i had no side effects and my workout was the best ever. i added 5 lbs. to all exercises and did more reps then ever and could do more but i was afraid of tearing a muscle or getting injured. normally after my workouts im exausted but today im still pumped!

I started using nano xp hardcore with creakic last week. I've used creakic and nano vapor before but not X9. I like the pumps I get from X9 but I think it works a little too well opening up your vr=eins for blood flow. Only after one week training with X9 I've developed hemmoroids, caused from an increase of blood flow in my veins. Now I'm going to take a week off to heal up. Honestly, I'm done using Muscletech products for good.

I'm going to try to keep this as quick and as simple as possible. My Buddies and I have been using MuscleTech products for years...almost and maybe since they 1st came about. HydroxyCut, CellTech, NitroTech, NaNoX9 etc...None of us, had ANY negative side effects...no rashes, no heart problems...no "bad days'. The ONLY side affect was RESULTS! Maybe because we followed directions, didn't OD, didn't drink alcohol while taking the product, we stay hydrated. I believe NaNoX9 is one of THE BEST NO products out there. The pumps... vascularity... etc, is beyond belief! Love it! I really believe that the people that have negative side effects are those that just have allergic reactions, not following directions, or just plain ignorant to the warning labels printed on the bottles. My respect, prays and blessing go out to any1 that has lost a loved one to any product. I do feel that the media should play a role in pulling cigarettes and alcohol off the shelves for they also cause deaths in a greater amount of people than any sports supplement. At least, the intentions of sport supplements are something beneficial.

I took two doses of naNOx9 throughout the day as recommended. The entire day was the day from hell. My body turned red and burned like fire, and my heartrate went up. This product is SCARY. I was in bed sick with a bad fever all night.

I've be taking naNOx9 for about two weeks now and I have to admit this product really does get your blood pumpin and I have had good results in the weightroom. The problem, for me, is I get this horrible rash that starts around my pecs and continues up and down both arms. It only last for two hours or so, but still. I actually can't believe that I have ignored this problem for this long, but I was just so amazed by the results in the gym that I couldn't stop using. This product was recommended to me by a good friend who never saw any side effects at all. I realized that this stupid rash isn't worth puttin up with, so I am going to stop using naNOx9 and try something else. My advise to someone who's contemplating using this product is try it because it does work but if you get the same side effect that i've been getting then take it back. So, is the effect worth the results? Not to me.

I recently purchased this product, and only used it for 3 times before I returned it. The first time I used it I felt tired and weak during my workout. I soon became hot and felt a small itching sensation come over my body...soon to become a hot itching fit. While I began to sweat, I thought I might just be getting sick so I went home. Turns out, every time I used this product the same thing would happen. Also, I'm generally a calm person, but while i was on this product I was very irritable and easily angered.Now that I've switched products, I feel fine. Please do not purchase NanoX9 Hardcore. If you do and have the same reaction, please report it.

I have used NO2 products in the past and I amj very impressed with the results. I get my good pumps as long as I keep hydrated and remember to eat. I do MMA, so the body building aspect is out, but my body strength has improved and my cardio is great. I have none of the side effects described and I'm on my second bottle.

I normally take NO explode, but tried this product, and like all other muscletech products it did nothing. My bench was worse (by 1 rep)on all my sets while using this versus NO explode. I didn't have any side effects at least though. I take 5 pills because Im 240lbs too if that is helpful

I used NanoX9 Hardcore by reccommendation from a salesman at GNC. It seemed to work a little bit but the side effects were awful. Within 15 minutes I had the worst rash of my life! I felt like my skin was on fire from nipple line up. It was hard to workout with this distraction so I quickly switched off of it to NO2 Black which is amazing! I will say that my friend tried my leftover NanoX9 and had no side effects.

I've got to say that this is one of the best N.O. supplements ive used.....and I have tried several, like NoXplode, NaNOvapor, and Black powder. This stuff gives you a great pump, and excelent vascolarty. I havent had any bad side effects, like many of you have described. But im only a couple of days in...so mabe they havent set in yet. I'll keep looking for any side effects....if any.

I tried this with sceptism as any Muscletech products i have used in the past have not worked and i have discontinued them. As i expected this was no different, the tablets are huge, very hard to swallow and being over 220lbs i took the recommended doses as it says on the box. The only effects i felt were severe nausea, and a nasty skin reaction which lasted about 50 minutes. After doing 4 sets of hyperextensions whilst on this stuff my lower back cramped up big style!! It saddens me that so many top athletes sell out and endorse Muscletech product as the only thing they have done for me is make me feel ill, which prevents me going to the gym. Do not waste your money or risk your health! This product is bad!
