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.
Immunity
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.
Immunity
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
ill
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.
Immunity
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 dosage calculator?
A peptide dosage calculator is a free tool that converts your vial size, bacteriostatic water volume, and target dose into an exact syringe draw volume. Instead of doing the reconstitution math by hand, you enter three inputs and instantly get the concentration of your solution and how many milliliters or syringe units to draw. This calculator works for single peptide compounds and multi-peptide blends.
How do I calculate peptide dosage from a vial?
To calculate your peptide dose, divide the total peptide content of your vial in micrograms by the volume of bacteriostatic water you added in milliliters. This gives you your solution concentration in mcg/mL. Then divide your target dose by that concentration to get your draw volume. For example, a 5mg (5,000 mcg) vial reconstituted with 2mL of BAC water gives a concentration of 2,500 mcg/mL. A 250 mcg dose would require drawing 0.1mL. This calculator automates all of those steps instantly.
How much Bacteriostatic water should I add to a peptide vial?
Most people add 2mL to 3mL of bacteriostatic water per vial, but the right amount depends on the dose you want to draw and the syringe size you are using. Adding 1mL to a 5mg vial gives you a concentration of 5,000 mcg/mL, making each dose very small in volume. Adding 2mL gives you 2,500 mcg/mL, which is easier to measure on a standard insulin syringe. A general guideline is to choose a volume that puts your typical dose somewhere between 10 and 30 units on a U-100 syringe. Use the calculator above to test different water volumes and find what works for your dose.
How are peptides different from proteins?
Both are made of amino acids, but peptides are much smaller than proteins. Because of their tiny size, peptides can act like tiny messengers in the body, sending specific signals to your cells to tell them exactly what to do.
