How It Works

Mitochondrial-Derived Peptide โ€” Neuroprotectant

Target โ†’ Anti-Apoptosis โ†’ Neuroprotection โ†’ Outcomes

๐ŸŽฏ
Target

FPRL1/FPRL2 Receptors + BAX (Apoptosis Regulator)

Humanin is encoded in mitochondrial DNA (like MOTS-c) and targets formyl peptide receptors and the pro-apoptotic protein BAX. By blocking BAX, Humanin prevents programmed cell death in stressed cells โ€” particularly neurons.

โšก
Cellular Signal

Anti-Apoptosis + STAT3 Activation โ†’ Cell Survival

Humanin blocks BAX-mediated apoptosis, keeping stressed cells alive. It also activates STAT3 signaling, promoting cell survival and reducing oxidative stress. The HNG analog is 1000x more potent than native Humanin.

๐Ÿ”„
Systemic Effect

Neuroprotection + Metabolic Support + Longevity

Protects neurons from amyloid-beta toxicity (relevant to Alzheimer's). Improves insulin sensitivity. Reduces oxidative stress across tissues. Like MOTS-c, Humanin levels decline with age, potentially contributing to age-related neurodegeneration.

What You Notice

Subtle โ€” Neuroprotection + Metabolic Support

Effects are primarily protective rather than immediately noticeable. Improved cognitive resilience and metabolic markers develop over weeks to months. This is a longevity and neuroprotection peptide โ€” benefits are long-term and preventive.

What Makes This Peptide Different

Humanin is the second major mitochondrial-derived peptide alongside MOTS-c. While MOTS-c targets metabolic pathways (AMPK/exercise mimetic), Humanin targets cell survival (anti-apoptosis/neuroprotection). Together they represent two complementary aspects of mitochondrial signaling that decline with age.

Protocol Notes
Mitochondrial-derived peptide. HNG analog is 1000x more potent than native Humanin.

Why This Dosing Protocol

Why the HNG analog? Native Humanin is relatively weak. The HNG (S14G substitution) analog is ~1000x more potent, allowing much lower doses for the same neuroprotective effect.

Why 5 on / 2 off? Standard peptide cycling approach to prevent pathway desensitization while maintaining protective effects.

FAQ

How does Humanin relate to MOTS-c and other mitochondrial peptides?

Humanin was the first mitochondrial-derived peptide (MDP) discovered in 2001, opening a new field of research. MOTS-c was discovered later in 2015. Both are encoded in mitochondrial DNA and have cytoprotective effects, but work through different mechanisms: Humanin primarily blocks apoptosis via BAX inhibition and STAT3 activation, while MOTS-c focuses on AMPK and metabolic regulation.

Why is Humanin studied for Alzheimer's disease?

Humanin was originally discovered in the brain of an Alzheimer's patient who had survived longer than expected. It protects neurons from amyloid-beta toxicity โ€” the protein that forms plaques in Alzheimer's brains. Humanin levels are lower in Alzheimer's patients, and research shows it can reduce neuronal cell death caused by various AD-related insults.

Does Humanin have effects beyond neuroprotection?

Yes, Humanin has broad cytoprotective effects. It improves insulin sensitivity and glucose metabolism (studied for diabetes), protects heart cells from ischemia damage (cardioprotection), reduces oxidative stress, and has anti-inflammatory properties. It's being researched for multiple age-related conditions beyond just neurodegeneration.

Why do Humanin levels decline with age?

Humanin is produced by mitochondria, and mitochondrial function declines with age. Lower Humanin levels correlate with age-related diseases including Alzheimer's, diabetes, and cardiovascular disease. Some researchers consider Humanin a biomarker of mitochondrial health and biological aging. Restoring Humanin levels is being studied as a potential anti-aging intervention.

What is HNG (Humanin analog) and why is it used in research?

HNG (S14G-Humanin) is a modified version of Humanin with a serine-to-glycine substitution at position 14. This single change makes HNG approximately 1000x more potent than native Humanin. Most research studies use HNG because it's more effective at lower doses, making it practical for experimental and potential therapeutic applications.

How long does reconstituted peptide last?

Once mixed with bacteriostatic water, peptides remain stable for up to 4 weeks when refrigerated at 2-8ยฐC (36-46ยฐF). Unopened powder can last 1+ year in the freezer. Get our complete Storage & Travel Guide.

Is this peptide legal to purchase?

Peptides sold "for research purposes only" are legal to purchase in the US, but are not FDA-approved for human use outside of specific medical applications. Always consult a healthcare provider before use.
