HelloPharmacist Scorecard of AgmaPure Agmatine Unflavored by Muscle Feast

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: agmatine sulfate. Agmatine is a compound derived from the amino acid arginine; it works in your body in several ways, including effects on blood pressure, blood sugar, and nervous system function.

There are no other active ingredients — just the agmatine itself.

Does it work?

Not established
Evidence for Intended Use · database check
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Agmatine's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: enhance nitric oxide and nutrient delivery to muscles.
  • We looked for evidence on: Athletic performance, Muscle strength, exercise endurance, workout recovery, exercise performance.
  • The closest evidence on file: Agmatine is rated "Insufficient Reliable Evidence To Rate" for Athletic performance (Natural Medicines).
  • Also on file: Agmatine is rated "Insufficient Reliable Evidence To Rate" for Muscle strength.

The evidence for agmatine across the conditions studied — alcohol use disorder, Alzheimer disease, anxiety, athletic performance, autism spectrum disorder, and bipolar disorder — is insufficient to rate it one way or another. That means we don't have enough reliable human data yet to say whether it works for these purposes.

If you're thinking about using it for a specific reason, it's worth talking that through with your doctor or pharmacist.

The evidence, ingredient by ingredient Agmatine

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Short-term use of agmatine appears generally well tolerated. The most common side effects reported in small studies were diarrhea, indigestion (dyspepsia), and nausea — and these showed up within a couple of days and went away once people stopped taking it.

The catch is that long-term safety in humans hasn't been well studied, so we don't know what happens if you take this for months or years. If you're pregnant or breastfeeding, there isn't enough safety data, so it's best to avoid this product.

Talk with your OB/GYN or midwife if you're considering it during pregnancy or while nursing.

Side effects, ingredient by ingredient Agmatine

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Agmatine.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 258 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, check your blood pressure medications and diabetes medications with your pharmacist. Agmatine can lower blood pressure and blood sugar, and combining it with drugs that do the same raises the risk of both dropping too low.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Agmatine sulfate is generally well tolerated short-term, but it's important to check it against your blood pressure and diabetes medications before you start — the interactions are real. We also don't have long-term safety data in humans.

If you take any prescription medications, run them through the checker on this page first, then have a conversation with your pharmacist.

Formula

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.
