Established pharmacology — curated for well-characterized compounds and AI-summarized otherwise. A blank (—) means no reliable single value is published (half-life figures for some peptides genuinely disagree across sources). Verify against primary sources such as FDA labels and ClinicalTrials.gov.
What is Dihexa?
Experimental nootropic peptide investigated for neuroprotection, memory, and stroke/spinal-cord recovery.
Full Dihexa profile, mechanism & studies →What is Humanin?
Humanin is a mitochondria-derived peptide that has garnered attention for its potential roles in cellular health and longevity. It is encoded by the mitochondrial genome and is involved in various cellular processes, including the regulation of apoptosis, inflammation, and oxidative stress. The peptide has been implicated in protective mechanisms against neurodegenerative diseases and metabolic disorders, suggesting its potential as a therapeutic agent in these conditions.

Fit reflects community-perceived effect profiles — not head-to-head trials. Read each peptide's studies before deciding.
Can you stack Dihexa and Humanin?
People sometimes combine peptides that target different pathways, but there is little controlled research on this specific pairing and the interactions aren't well characterized. Because neither compound is FDA-approved, we don't publish stacking or dosing protocols here. Any combination should be discussed with a qualified clinician.

Frequently asked questions
Is Dihexa or Humanin better?
It depends on your goal. Dihexa is strongest for neuro; Humanin for neuro. Humanin has more indexed studies (19). See the goal-by-goal breakdown above.
Is Dihexa or Humanin better for weight loss?
Humanin shows the stronger metabolic & appetite profile (3.0/5) in the AI-assigned effect profile — though weight-loss outcomes depend on the individual and the evidence base.
Is Dihexa or Humanin better for muscle?
Both land close on the muscle & body-composition axis.
Which has more research, Dihexa or Humanin?
Dihexa has 11 approved studies indexed (Human clinical); Humanin has 19 (Human evidence). Higher counts mean more to read, not proven superiority.
Can you stack Dihexa and Humanin?
Some users combine peptides, but there's little controlled data on this specific pairing, and interactions aren't well characterized. We don't publish stacking protocols for compounds that aren't FDA-approved. Discuss any combination with a qualified clinician.
What are the side effects of Dihexa vs Humanin?
Dihexa: no community-reported effects logged yet. Humanin: none logged yet. These are anonymous reports, not incidence rates — see each profile.
Is Dihexa or Humanin FDA-approved?
Dihexa is a research-use compound and is not FDA-approved. Humanin is not FDA-approved. Research-use status is not a legal clearance to compound or use in humans.
Is Humanin better than Dihexa?
For neuro, Humanin has the edge; for neuro, Dihexa does. Neither is universally "better" — it's goal-dependent, and both should be weighed against their evidence base above.

Regulatory & legal status
Dihexa and Humanin are research-use compounds and are not FDA-approved for human use. FDA approval and compounding rules for peptides change frequently, and research-use status is not a legal clearance for human use. The FDA does not review compounded drugs for safety, effectiveness, or quality. Verify current status with primary sources before acting. Last reviewed November 4, 2026.
