Product Claims

Troxyphen Elite Advanced Formulation from truDERMA came in a close second. It claims to boost nitric oxide, build lean muscle and decrease body fat

Troxyphen contains some impressive key ingredients and blends. Their Nitric Oxide Boost Blend includes several forms of L-Arginine plus L-Citrulline.

However, some of the added ingredients (such as gelatin) were not suitable for vegetarians, vegans and those with meat allergies/intolerances.

We did note that it contained caffeine and green coffee extract. On their label, they also warn not to take this before going to bed. We felt that those people who workout in the evening may find sleeping an issue after taking this supplement.

Value

We felt that Troxyphen didn't provide enough options for consumers to choose and tailor their order package. They offer a one time purchase price, with no savings for multiple bottle purchases.

We were unable to find a money back guarantee. This weakened the product for us.

Conclusion

Troxyphen were almost there with a top quality product but we felt that there were several key elements missing. The ingredients are natural and it contains the top key ingredients clinically proven effective for boosting nitric oxide. However, the addition of gelatin and caffeine brought with it negative concerns which lowered the product’s appeal for us. Also, the lack of multi bottle purchasing options, which in the long run, can lower the cost of each bottle by a considerable amount left us also feeling a little let down by this product.

Product Claims

UberNO2 use natural ingredients that they claim builds muscles fast

Ingredients

UberNO2 contains some impressive key ingredients namely L-Arginine, Citrulline Malate, and Beetroot. However, the L-Arginine it contains only provides 2 subtypes as oppose to our top product which provided 4, therefore, because it is all about the ultimate boost, we felt this lowered the effectiveness of the product. The manufacturer also considered the wider market too, by making their capsules vegan friendly, gluten free and Kosher and Halal safe.

Value

We felt that UberNO2 offered a good range of options for the consumer for multi bottle purchase, but there wasn't a clear money back guarantee, we think that consumers can’t feel totally confident to place an order without experiencing problems. They are a US based manufacturer.

Conclusion

UberNO2 offers a few very positive elements. The ingredients are spot on however, the addition of several subtypes of L-Arginine would increase the quality of this product. We like the fact they operate within the US and therefore fall under the FDA operating regulations but would benefit from offering a clear money back guarantee. Overall, more benefits than negatives.

Product Claims

ISO N.O. is produced by ANS Labs designed to increase blood flow, vascularity and endurance.

The ingredients are mainly natural and offered as a ‘Nitro-Vascular ‘Blend’. This sounds good, especially when it contains L-Arginine and L-Citrulline. However, we remain unclear exactly how much dosage of the blend lends itself to these amino acids versus the other less effective ingredients. For all we know, there could be minute ineffective doses of the key ingredients and huge amounts of the other less effective ones. We therefore have to trust the manufacturers that they made a decent product, but we can't be sure. This raised concerns for us as to the effectiveness of this product.

Although the company is well established, we could not properly establish a good level of customer feedback due to the limited reviews of the product we found. This could suggest that the product's effectiveness is weak or something else that we were unable to explain.

Value

We felt that the price of $84.99 was very expensive for this product. Although, they do offer free 2-day shipping and a member discount through GNC.

Conclusion

With the lack of reviews and the unclear breakdown of the ingredients contained within the blend, together with the inflated price we placed this product in our # 4 ranking. Its regaining features however, include the fact that they use all natural ingredients plus it does contain L-Arginine and L-Citrulline, oh, and that it’s sold in GNC, so its easy to get if you run out!

Product Claims

Our #5 pick is Mascugen. It is claimed to boost nitric oxide and testosterone, muscle growth, male drive, energy and libido.

All ingredients it said to be natural and a ‘bio-product’. We found the inclusion of a good blend of amino acids - L-Arginine. However, that was it. There was no other herbal, vitamin or mineral backup. This definitely weakened the product for us, which was a shame because they had a good base start.

Another minus was the fact that it is offered in a gelatine capsule. This is a big negative for vegans, vegetarian, some religious groups and meat sensitive consumers.

This company includes testimonials, but only two! Its not enough for us to ascertain whether consumers are happy with this product.

Value

This company do offer a 60 money back guarantee. This is a positive element. Plus, they offered several bulk buy options that provide discounted rates.

Conclusion

This product has some good points, the main base key ingredients are excellent. However, it needed more, it was almost like the ingredients list was incomplete. The fact that this contains gelatin was a big minus. Together with its limited customer reviews we had to place this at the bottom of our top picks. However, we liked the fact they have a money back guarantee and that customer satisfaction is important to them.
