HelloPharmacist Scorecard of AgmaPure Agmatine Unflavored by Muscle Feast

Four independent checks of what is known — a summary of the available information, not a grade of the product itself.

Evidence for Intended Use
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

The stated purpose hasn't been mapped to our evidence data yet.

Why this rating?

Formulation

Muscle Feast AgmaPure Agmatine is designed to enhance nitric oxide production and improve nutrient delivery to muscle cells. It can boost endurance, as well as decrease recovery time. We have chosen AgmaPure Agmatine, because it is a unique green, high purity agmatine sulfate. It's produced by a natural biological process and away from the neurohazard impurity Arcaine, which exists in almost all the other brands of Agmatine Sulfate.

Suggested/Recommended/Usage/Directions

Suggested use: As an adult dietary supplement, take one serving (1500 mg) in 6-8 ounces of water, 1-2 times per day or as directed by your doctor. Mix 1 level (1500 mg) scoop with 6-8 oz. water or beverage of choice up to 2 times a day.
