Best Peptide Stack for Immune Support

28-amino-acid immune peptide from thymus tissue. Strengthens T-cell maturation, boosts natural killer cells, and balances immune response. Tested in 30+ trials, approved in 35+ countries for hepatitis, HIV support, and infections. No serious side effects.

Derived from the thymus gland. Restores immune function and has shown life-extending properties by reactivating the aging immune system.

Your body's natural antibiotic peptide. Fights bacteria, viruses, and fungi, breaks up biofilms, and supports wound healing while modulating immune response.

Thymus hormone requiring zinc as a cofactor. Supports proper immune cell development and thymus regeneration. Production declines with age.

One of the smallest active peptides — just two amino acids. Supports thymus function and proper immune cell development.

Neuropeptide with powerful anti-inflammatory properties. Widely used in mold illness (CIRS) protocols. Regulates gut and lung inflammation, supports immune balance.

Enhanced Selank with better stability and bioavailability. Delivers stronger anxiolytic and immune-boosting effects than regular Selank.

Russian anxiolytic peptide working on GABA, serotonin, and enkephalin systems. Eases anxiety without sedation or dependence risk. Also boosts immunity. Decades of clinical use.

Longevity peptide from the pineal gland. Activates telomerase to protect DNA caps and restores melatonin production. Russian studies showed 11-16% lifespan increase in animals.
