Immunity Peptide Cheat Sheet — Research Notes
Key considerations and protocol notes for each peptide in this cheat sheet.
Cognitive
sel
Longevity
Selank is a synthetic heptapeptide derived from tuftsin with anxiolytic, nootropic, and immunomodulatory properties; it is most commonly administered as a nasal spray and is noted for reducing anxiety while enhancing focus and memory without sedation or dependence.
Longevity
thymu
Immunity
Thymulin is a thymic nonapeptide hormone that promotes T-cell differentiation and immune regulation, with research suggesting anti-inflammatory and anti-aging properties. It requires zinc as a cofactor for biological activity and is studied for immune restoration, particularly in age-related immune decline.
Longevity
cry
Immunity
Crystagen is a short peptide bioregulator (tripeptide) derived from the cerebellum, primarily used to support brain and nervous system function, cognitive performance, and neuroprotection. It is commonly cycled in the Khavinson bioregulator protocol and may support neuronal health and age-related cognitive decline.
Cognitive
sel
Longevity
Blend of Selank, Semax, Pinealon, and PE-22-28 targeting mood, memory, focus, and neurogenesis. Nasal spray formulations need no BAC water; injectable versions use 1–2 mL. Frequency: daily or 5 on/2 off. Dose is product-dependent.
Longevity
thym
Immunity
Thymogen (Glu-Trp) is a synthetic dipeptide derived from the thymus gland that modulates immune function by stimulating T-cell maturation and enhancing cellular immunity. It is used to support immune restoration, particularly in immunodeficient states, and has been researched for its anti-aging and immunomodulatory properties.
Healing
thymos
Longevity
Thymosin Beta-4 (TB-500) is a naturally occurring peptide that promotes tissue repair, reduces inflammation, and accelerates healing of muscles, tendons, ligaments, and skin. It works by upregulating actin and promoting cell migration and angiogenesis, making it popular for injury recovery and wound healing.
Longevity
liv
Immunity
Livagen is a short tetrapeptide (Lys-Glu-Asp-Ala) developed by the St. Petersburg Institute of Bioregulation, primarily studied for its ability to activate chromatin and restore gene expression in immune and cardiac cells, supporting longevity and cardiovascular health. It is used in peptide bioregulator protocols alongside other Khavinson peptides to support immune function and slow age-related cellular decline.

Frequently asked questions
What is a peptide protocol?
A peptide protocol is a structured research plan that specifies which peptides to study, the quantities and frequencies used in research settings, and the duration of the study period. Research protocols often combine multiple peptides that act on complementary biological pathways—such as tissue repair, cognitive function, or metabolic regulation—to investigate broader or synergistic effects. These protocols are intended for research purposes only and are not a guide for human consumption.
How is peptide dosage calculated from a vial for research?
In a research context, the concentration of a reconstituted peptide solution is calculated by dividing the total peptide content of the vial in micrograms by the volume of bacteriostatic water added in milliliters. For example, a 5mg (5,000 mcg) vial reconstituted with 2mL of BAC water yields a concentration of 2,500 mcg/mL. This information is provided for reference and laboratory calculation purposes only — not as a guide for human use.
How much bacteriostatic water is typically used for peptide reconstitution in research?
Research protocols commonly reconstitute peptide vials with 2mL to 3mL of bacteriostatic water, though the appropriate volume depends on the target concentration needed for a given study. Adding 2mL to a 5mg vial yields a concentration of 2,500 mcg/mL. This information is provided strictly for laboratory and research reference — not as instructions for human use.
How are peptides different from proteins?
Both are composed of amino acids, but peptides are significantly smaller than proteins. Due to their size, peptides can function as precise signaling molecules, binding to specific receptors and triggering targeted biological responses—such as stimulating growth hormone release, promoting tissue repair, or modulating immune activity. These mechanisms are the subject of ongoing scientific research.
