Beta-alanine has 40 trials and a small but real effect size that depends entirely on exercise duration. Agmatine has no human performance trials at all. Here is the honest comparison.
Agmatine and creatine both come out of arginine metabolism and both sit in pre-workout tubs, which is where the similarity ends. One has hundreds of human trials, the other has none for exercise.
We text-searched the 2026 WADA Prohibited List directly. Agmatine appears zero times. Here is what that does and does not protect a tested athlete from.
Fibromyalgia is a central sensitisation disorder and agmatine is a GluN2B-selective NMDA antagonist, which is why the question gets asked. Here is why the strongest agmatine pain data is also the hardest to apply.
In the standard animal model of MS, agmatine restored a blood-brain barrier tight junction protein and lowered the enzymes that break the barrier down. Why that’s a research lead, not a treatment.
Rat TBI studies show agmatine cuts brain edema by suppressing aquaporin water channels and reduces apoptotic cell death. Here’s the mechanism, and the large gap between it and human use.
What the actual PubMed-indexed research says (and doesn’t say) about agmatine and testosterone: a 2025 testicular-injury protection study and a 1994 hormone-release finding, not a human boosting trial.
