Stacked NO is a nitric oxide booster from Ronnie Coleman. Coleman is a former Mr. Olympian, but the products in his supplement line do not have a history of success. As of March 2013, Stacked NO is in preorder status. Consumers can order the product, but supplements will not be received for at least four weeks. The product description for Stacked NO is only one paragraph long, but there is a huge picture of the product ingredients. There is one small proprietary blend in the mix, but most of the ingredient amounts are listed – no matter how absurd those amounts are.

List of Ingredients

Ingredients:

  • Niacin
  • Vitamin B12
  • L-Citrulline
  • Agmatine
  • L-Ornithine HCL
  • HICA
  • AstraGin

Product Features

The first two ingredients – niacin and vitamin B12 – are also found in your everyday multivitamin. These ingredients are not an active part of the muscle-building magic Coleman claims comes with taking Stacked NO. While we normally would just ignore these ingredients, we find it hard to ignore the 0.75 mcg of vitamin B12. Typical vitamin B12 supplements provide between 500 and 10,000 mcg of the vitamin, not 0.75 mcg. There is no sense in adding this tiny amount of vitamin B12 to the mix.

Niacin is commonly added to bodybuilding supplements for the flush. You can quickly find hundreds of bodybuilders that chew niacin tablets every day to flush the body of toxins and up nitric oxide, but these bodybuilders are taking 500 to 1,000 mg of niacin, not the 12.5 mg available in Stacked NO.

L-Citrulline is a precursor of nitric oxide. In theory, adding more precursor could lead to more nitric oxide, but Coleman doesn’t bother to add research into how this precursor is converted to nitric oxide or even if it converts at all.

Agmatine is actually a nitric oxide inhibitor that may cause a rise in arginine after taking the supplement. Agmatine is best taken first thing in the morning, though much of the supplementation time depends on food consumption, overall supplement schedule and other factors. Agmatine has a short half-life so it will not help boost nitric oxide all day as claimed.

L-Ornithine is often taken to boost natural levels of human growth hormones. The amino acid may only be effective when taken while fasting – but few bodybuilders are fasting. According to one study, L-Ornithine had no effect on human growth hormone levels.

HICA is also known as leucic acid or Leucine. There are few bodybuilders sold on this ingredient. Most prefer to stick with Leucine as HICA shows no clinical signs of being more effective than Leucine. In one study, users reported less muscle soreness, but overall muscle pumps and nitric oxide was not affected.

  • Ingredients listed online.
  • May reduce muscles soreness.

Disadvantages

  • Useless amount of vitamin B12 is added.
  • Not enough niacin to promote flush.
  • Not currently available for delivery.

Conclusion

It doesn’t look like Stacked NO is a supplement Ronnie Coleman will make much money off of. The supplement is a poor excuse for a NO booster and there is no clinical support listed in the brief product description.
