Humanin
Also known as: HN
Humanin is a mitochondrial-derived peptide encoded within the 16S ribosomal RNA gene. It was discovered through its ability to protect neurons from Alzheimer's disease-related toxicity and is studied for neuroprotection, metabolic regulation, and anti-aging applications.

Prices observed from public storefronts (last 24h), normalized to $/mg. "Evidence" is Merit's 0–100 Merit Score, derived only from observable verification evidence (methodology on /about); "Purity" is the latest independent COA. Some buy links are affiliate links — Merit may earn a commission at no extra cost to you, and where a vendor offers one, the code shown gets you a discount at their checkout. Affiliate status never affects price data, ranking, or the Merit Score (full policy on /disclosure). Research use only.
