Thymosin Alpha-1
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.
Thymalin
Derived from the thymus gland. Restores immune function and has shown life-extending properties by reactivating the aging immune system.
LL-37
Your body's natural antibiotic peptide. Fights bacteria, viruses, and fungi, breaks up biofilms, and supports wound healing while modulating immune response.
Thymulin (Zinc Thymulin)
Thymus hormone requiring zinc as a cofactor. Supports proper immune cell development and thymus regeneration. Production declines with age.
Vilon
One of the smallest active peptides ā just two amino acids. Supports thymus function and proper immune cell development.
VIP (Vasoactive Intestinal Peptide)
Neuropeptide with powerful anti-inflammatory properties. Widely used in mold illness (CIRS) protocols. Regulates gut and lung inflammation, supports immune balance.
N-Acetyl Selank Amidate
Enhanced Selank with better stability and bioavailability. Delivers stronger anxiolytic and immune-boosting effects than regular Selank.
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.
Epithalon (Epitalon)
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.
Best Synergy Combos
Two-tissue Khavinson bioregulator pairing. Epithalon (Ala-Glu-Asp-Gly) influences telomerase activity in pineal/peripheral cells; thymalin influences thymic epithelial signaling. Both data sets originate from the same Russian research group and have not been independently replicated.
Adaptive Ć innate immunity. TĪ±1 (FDA-approved for hepatitis B in 35+ countries) modulates dendritic-cell IL-12 secretion; LL-37 / cathelicidin is a direct antimicrobial peptide active against gram-positive and -negative pathogens and biofilms.
Thymic-axis pairing. TĪ±1 (FDA-approved) modulates mature T-cell function; thymalin (Khavinson) influences thymic epithelial regeneration in preclinical and small Russian human studies.
HPA-axis-modulated immunity. Selank reduces stress-induced glucocorticoid output (which suppresses Th1 immunity); TĪ±1 directly engages dendritic-cell maturation.
