Humanin vs Thymalin

Q: Can you stack Humanin and Thymalin?

Humanin (cognitive) and Thymalin (immune) are in different categories and are sometimes researched together in combined protocols. Consult a licensed provider before combining any compounds.

Head-to-head comparison of Humanin and Thymalin — mechanism, dosing, side effects, legal status, and pricing.

Humanin

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.

Thymalin

Thymalin is a heterogeneous polypeptide extract from calf thymus (a mixture, not a single defined peptide) developed in the 1970s by V. Kh. Khavinson and V. G. Morozov at the Military Medical Academy / St. Petersburg Institute of Bioregulation and Gerontology. Registered as a pharmaceutical in the USSR/Russia for immunocorrection. Distinct from Thymulin (Bach's zinc-dependent nonapeptide pGlu-Ala-Lys-Ser-Gln-Gly-Gly-Ser-Asn, originally called FTS) and from Thymosin alpha-1 (a 28-amino-acid synthetic peptide). Not FDA-approved in the US; research-use only.

Humanin Research Summary

Hashimoto et al. (2001) discovered humanin through functional screening for neuroprotective factors against amyloid-beta toxicity. Yen et al. characterized the S14G-Humanin analog (HNG) as 1000x more potent. Muzumdar et al. demonstrated that humanin improves insulin sensitivity and reduces visceral fat in animal models. Circulating humanin levels decline with age and correlate inversely with Alzheimer's biomarkers. Cohen et al. showed humanin's role in the GH/IGF-1 axis through IGFBP-3 interaction. No human clinical trials have been conducted — all dosing is extrapolated from preclinical data.

Thymalin Research Summary

Evidence base is almost entirely single-lab (Khavinson/Morozov, St. Petersburg). Long-term observational work in elderly Russian cohorts reported reduced all-cause mortality and lower incidence of respiratory infections with Thymalin (alone or with Epithalamin) over 6–8 years, but these were not blinded Western RCTs and have not been independently reproduced. No FDA-registered clinical trials.

Can you stack Humanin and Thymalin?

Humanin (Cognitive) and Thymalin (Immune) are in different categories and target different biological pathways. This is a common pattern in multi-compound research protocols. Researchers should monitor the biomarkers from both profiles and watch for interactions listed in each compound’s contraindications. Consult a licensed healthcare provider before combining any research compounds.
