Agmatine vs Taurine: One Has Meta-Analyses, One Has Mechanism
Taurine has 23 randomised trials and a small acute performance effect that the authors themselves rate as low certainty. Agmatine has none. What that asymmetry should mean for your stack.
Agmatine Shelf Life, Clumping and Storage: Why Your Powder Turned Into a Brick
Agmatine sulfate is hygroscopic, so clumping is expected rather than a defect. Here is what clumping does and does not tell you, and how to store powder so it stays scoopable.
Agmatine, Stress Resilience and PTSD: A Contradiction Worth Understanding
Acute stress raises brain agmatine nearly fourfold. Chronic stress depletes it. That apparent contradiction is the most useful thing in this literature, and no PTSD study exists.
Agmatine and Eye Pressure: The Glaucoma Research, and a Retracted Study You Will See Cited
Topical agmatine cut retinal ganglion cell loss from 55% to 19% in a rat glaucoma model. Why that doesn’t transfer to capsules, and the retracted paper still circulating as evidence.
Agmatine for ADHD: Glutamate Modulation and the Unproven Case for Off-Label Use
A 2020 human study found ADHD children have elevated (not deficient) agmatine, likely compensatory. A 2021 rat study showed agmatine improved ADHD-relevant cognition. Neither supports agmatine as a human ADHD treatment.

Agmatine vs. Memantine: Two NMDA Antagonists with Very Different Risk Profiles
Agmatine and memantine both target NMDA receptors, but via different mechanisms and with very different safety profiles. Here’s what the evidence shows.
Agmatine Supplements and Third-Party Testing: How to Read a Certificate of Analysis
Learn what third-party testing and a Certificate of Analysis mean for agmatine supplements, and how to verify purity, potency, and safety before you buy.
