- Preliminary human Cerebrolysin: A Heavily Studied Brain Peptide Whose Best Trials Came Up Short Cerebrolysin has more human trial data than most research peptides, yet its largest rigorous stroke trial was neutral and independent reviews find little benefit.
- Animal only Dihexa An angiotensin IV-derived oligopeptide studied in animals for synaptogenesis and cognition; it has never been tested in humans, and its foundational mechanism paper was retracted in 2025.
- Strong human Methylene Blue A synthetic redox dye with one strong, FDA-approved use (treating methemoglobinemia) and a long list of popular biohacking claims that human evidence does not support.
- Preliminary human Selank A Russian-developed anxiolytic peptide approved in Russia but unproven by Western standards; human trials are small, early, and single-country.
- Preliminary human Semax A Russian-approved nootropic/neuroprotective peptide whose human evidence is real but small, mostly Russian-language, and methodologically thin.
