AgmaGen Review

AgmaGen is marketed as a pre-workout supplement by RSP Nutrition. It comes in two flavors – Fruit Punch and Pomegranate, at $22.19.

Claimed to promote:

  • Muscle pumps
  • Muscle recovery
  • Endurance
  • Fat loss

For a product that only contains one ingredient, it claims to do a lot. We’ve analyzed RSP Nutrition’s pre-workout supplement, to see whether it can live it its expectations.

Take a look:


About the Company

RSP Nutrition are a supplements company based in Miami, FL, USA. They market a range of products, from pre-workout to fat burner supplements.

The Ingredients and How They Work

Interestingly, this product only contains one ingredient – Agmatine sulfate. There are ingredients in pre-workout supplements that offer numerous benefits, such as Caffeine, which boosts strength and endurance, as well as cognition.

We’ve analyzed Agmatine Sulfate, to see whether it’s good enough to be the only ingredient in a product.

See for yourself:

Agmatine Sulfate

This is extracted from L-Arginine by removing a carboxylic acid group. It’s shown to be effective in reducing pain and depression in doses between 1,300-2,670mg.

Agmatine Sulfate has been used in AgmaGen, as it’s believed to improve nitric oxide levels due to its ability to inhibit nitric oxide synthase enzymes.

However, no human studies have proven this to be true. This is worrying, as the whole basis of RSP Nutrition’s pre-workout supplement is that it raises nitric oxide levels, which in turn would lead to increased endurance and muscle protein synthesis.

As Agmatine Sulfate’s hasn’t been well-studied, and it’s the only ingredient in AgmaGen, it’s likely that this product is ineffective in delivering on it’s claims (enhanced muscle pumps, recovery, endurance, and fat loss) – especially as this ingredient’s been seriously under-dosed at 500mg.

RSP Nutrition should’ve at least raised the dose of this ingredient to its optimal amount, between 1,300-2,670mg.

Banned in Europe

What’s even more worrying is that it’s been banned in the EU – so if you’re reading this from the UK, France, or anywhere in Europe, you won’t be able to try this product.

AgmaGen’s single ingredient seems to be ineffective in delivering benefits to aid your gym session.

Side Effects

The reason why Agmatine Sulfate’s been banned in the EU is because it caused side effects. These included:

  • Nausea
  • Vomiting
  • Diarrhea

AgmaGen Review Conclusion

If a company’s going to only offer one ingredient, then they should simply name the product as that ingredient – Instead of AgmaGen, RSP Nutrition should’ve named this product “Agmatine Sulfate”.

However, this is clearly a marketing trick – if you don’t look at the ingredient list, you might think there’s numerous ingredients contained, instead of just one.

We recommend that you search for a pre-workout supplement with a full nutrient profile, including key ingredients such as L-Theanine, Caffeine, and Creatine Monohydrate.
