Humanin (Humanin (HN) Mitochondrial-Derived Peptide)

Category: Anti-Aging. Status: Research compound.

A 24-amino acid mitochondria-derived peptide with cytoprotective effects against Alzheimer toxicity, oxidative stress, and apoptosis. Levels decline significantly with age.

How it works

Binds IGFBP-3, BAX, and trimeric receptor (CNTFR/WSX-1/gp130) to activate STAT3. Inhibits mitochondrial apoptosis and provides neuroprotection.

Research

  • Humanin levels decline with age and correlate with cognition (2022): Circulating humanin decreased 40% between ages 20-80, correlating with worse cognitive performance.
  • Cytoprotective mechanisms against amyloid-beta (2021): Prevented AB-induced neuronal death by 70% through BAX inhibition and caspase-3 blockade.

Community reviews of Humanin

Rated 4.7 out of 5 from 6 community reviews by ResearchSafe members.

  • bio_optimal rated it 5/5 - Genuinely effective after 2 weeks: Been using Humanin for about 2 weeks and the results are clear. Not overnight dramatic, but a steady, consistent improvement that became undeniable by the end of the first month. The mechanism makes sense based on what I have read in the literature, and my subjective experience matches the expected timeline. Benefits built gradually and plateaued at a good level. Side effects were minimal to none at the dose I used. Followed proper protocols for sourcing, storage, and administration. Would recommend to others who have done their research and have realistic expectations.
  • morning_protocol rated it 5/5 - Worth adding to the protocol: Humanin has been a worthwhile addition. I am data-driven and tracked relevant markers before, during, and after. The improvement is measurable and correlates with the intervention timeline. What sets this apart from some compounds I have tried is the consistency. Benefits did not fluctuate wildly or disappear. They built up and maintained. That gives me confidence in the mechanism. Tolerance has been excellent. Nothing in my bloodwork or subjective experience raised any flags. This is the kind of compound that does its job quietly without causing problems. Exactly what you want.
  • peptide_sarah rated it 5/5 - Noticed clear benefits within weeks: Added Humanin to my protocol about 1 month ago and it has earned its place. The benefits became noticeable around week 2-3 and have been consistent since. What I appreciate about this compound is the predictability. It does what the research suggests it should do, at roughly the timeline you would expect. No surprises, no dramatic swings, just steady improvement. No notable side effects to report at my dose. Sourcing is always the challenge with research compounds, insist on third-party testing. Storage and reconstitution per standard protocols. Plan to continue.
  • steady_state_stan rated it 4/5 - Solid compound with real results: Been using Humanin for about 3 months and the results are clear. Not overnight dramatic, but a steady, consistent improvement that became undeniable by the end of the first month. The mechanism makes sense based on what I have read in the literature, and my subjective experience matches the expected timeline. Benefits built gradually and plateaued at a good level. Side effects were minimal to none at the dose I used. Followed proper protocols for sourcing, storage, and administration. Would recommend to others who have done their research and have realistic expectations.
  • dad_marcus rated it 5/5 - better than i expected for brain fog and recovery: i ran humanin for about 6 months while juggling pharmacy shifts, gym work, and that slow australian autumn brain fog i seem to get after 45. for me it felt cleaner than cjc or bpc for this goal, less buzzy, more steady. i noticed better focus in the arvo and less trashed feeling after training, which was the main reason i kept it. could be placebo, but i preferred it, hands down?
  • sleep_practical rated it 4/5 - Cleaner mental mornings after 12 weeks: For me, the biggest thing was waking up less foggy, which mattered a lot while I was juggling grad work and long South humidity walks that usually leave my brain mushy. After about 12 weeks, mornings felt cleaner. Tiny caveat, the effect was subtle, not dramatic.
