Below we take an in-depth look into Hi-Tech N.O. Overload, to see whether this product works as advertised.
Hi-Tech N.O. Overload is a pre-workout that primarily aims to boost the production of Nitric Oxide. It achieves this by providing customers with a source of arginine, as well as a group of ingredients that inhibit an enzyme called arginase. When supplemented together, these ingredients supposedly increase NO production, widen the blood vessels, and improve overall exercise performance.
The full list of potential side effects is quite long, so we recommend checking out the Side Effects tab for the full list.
The most likely side effects that customers might encounter include lowered blood pressure, stomach issues, bloating, jitters, sleeplessness, heart palpitations, and headaches.
N.O. Overload tends to retail for around $29.95 for a pack containing 39 scoops (although the manufacturer’s website sells it for an absurd $49.95). The cheapest prices we found on the Internet were on All Star Health ($20.99) and iHerb ($24.75).
This product suffers from a serious lack of important information that makes purchasing it very risky. We were only able to find three customer reviews discussing this product on iHerb’s webstore, and the manufacturer has made the unfortunate decision to hide the ingredient quantities used in this product. To top it all, there is no money-back guarantee available to reimburse disappointed customers.
On the face of it, we would guess from the ingredients list that this product should work well to boost Nitric Oxide levels, but likely fails to provide much of a burst of energy (due to its reliance on weak stimulants like theobromine and yerba mate).
Overall, we recommend sticking with more established products backed by real evidence and better reputations.
We do not recommend Hi-Tech N.O. Overload to our readers.
Hi-Tech N.O. Overload is a pre-workout supplement that promises to boost exercise performance by increasing Nitric Oxide production. This relatively complex blend utilises dozens of active ingredients to supposedly provide multiple benefits, including shortening exercise recovery periods, boosting energy, inhibiting arginase production, and more.
N.O. Overload is manufactured by Hi-Tech Pharmaceuticals, a US-based supplement store based in the USA. Hi-Tech Pharma (as they are often called) is known mainly for their extraordinary history of litigation, having fought long and protracted legal battles with the FTC, FDA, respected university professors, medical authorities, and rival companies. The company can be contacted via the details supplied on their official website.
The directions for use are as follows:
N.O. Overload is a pre-workout formula, and claims to improve exercise performance in the gym. It supposedly achieves this by providing an energy boost, a “muscle cell volumizing” effect which results in enhanced muscle growth, and a shortened post-workout recovery period.
As the name of the product suggests, it also claims to boost Nitric Oxide production. This mechanism is known to result in vasodilation, which is where the blood vessels can widen and allow more blood to flow to the muscles, thus improving their efficiency in the gym. Unlike other manufacturers, Hi-Tech Pharmaceuticals claim to provide a more reliable NO-boosting mechanism that provides better results than comparable products. Their supposedly superior process works by inhibiting the enzyme arginase, which is known to break down l-arginine (the precursor of NO).
Hi-Tech Pharmaceuticals fail to disclose the proper ingredient quantities and there are very few customer reviews, which makes it hard to gauge the effectiveness of this product. On the face of it, the formula uses a good blend of arginine and arginase inhibitors, which should boost NO production and improve muscular performance. There are many filler ingredients however, and the product’s energy boost matrix is surprisingly weak-looking for a Hi-Tech Pharmaceuticals product.
The ingredients found in Hi-Tech N.O. Overload are listed below. Unfortunately, the manufacturer fails to provide ingredient quantities for virtually every ingredient, which makes it nearly impossible to estimate how effective the formula is. The quantities listed that are listed are correct for 1 scoop (8g) of powder.
This product can increase Nitric Oxide levels, and this can, in turn, lower blood pressure; anyone who already has low blood pressure, or who are taking medications that affect blood pressure, should avoid taking supplements that claim to increase NO levels.
L-arginine can cause some side effects including abdominal pain, bloating, diarrhoea, blood abnormalities, airway inflammation, worsening of asthma, and low blood pressure.
The mild stimulant effect created by the year mate and theobromine can cause headaches, an increased heart rate, increased blood pressure, heart palpitations, increased urination, dehydration, jitteriness, dizziness, and insomnia.
Acacia Rigidula is a stimulant, and it can cause increases in blood pressure and heart rate and heart palpitations. It can also cause false positives on drug tests used to detect the presence of amphetamines in the bloodstream.
Quebracho Blanco has sometimes been associated with drooling, headache, sweating, dizziness, stupor, and sleepiness. In large doses, it can cause nausea and vomiting. Although Tyrosine is tolerated generally in very high doses, it can cause some side effects including nausea, headache, fatigue, heartburn, and joint pain.
Not suitable for pregnant or breastfeeding women. Not suitable for anyone under the age of 18. If you are taking any medications or are unsure about the suitability of this supplement for you, consult your doctor before purchase.
We weren’t able to find much in the way of customer reviews online; the three comments listed below were pretty much all there was to find. As you can see, the three customers below were satisfied with their purchase, although one negative comment was directed to the odd smell and taste of the powder.
Best pump pre workout ever try give excellent motivation and mood with good vascularity only the taste and smell are not that good but acceptable
This is a decent pump product because it definitely does the trick and is a pretty decent price as well. One thing that I do not like about this is that their are other pump products that contain about the same ingredients but from other brands that are much more popular. Most people would rather get those, but this is good.
Well received and awaiting more cheaper to buy again
On the official Hi-Tech Pharmaceuticals website, no mention is made of a money-back guarantee or a returns policy of any kind.
N.O. Overload is available to purchase from a number of online retailers, including All Star Health, iHerb, DPS Nutrition, iSupplements, Best Price Nutrition, and the Hi-Tech Pharmaceuticals website.
