- Epitalon
- Telomerase activation via TERT gene upregulation
- Age-related immune decline, stem cell exhaustion, longevity research
- 5–20 µg/kg, 10–20 day cycles
- 14–21 days at 2–8°C
- Best alternative for longevity-focused immune research where replicative senescence is the limiting factor. Doesn't replicate thymic function but addresses upstream cellular aging
- Pinealon
- Neuroendocrine modulation through pineal-hypothalamic axis
- Circadian immune dysfunction, neuroinflammation, brain-immune interactions
- 10–30 µg/kg, 10–30 day cycles
- 14–28 days at 2–8°C
- Ideal for protocols examining immune-brain axis or circadian rhythms. Mechanistically distinct from thymic bioregulation
- GHK-Cu
- Extracellular matrix remodeling and copper-dependent angiogenesis
- Wound immunity, tissue repair, implant integration, localized immune modulation
- 0.5–2.0 mg/kg topical or subcutaneous
- 7–14 days at 2–8°C (oxidation-sensitive)
- Best for structural immune research where tissue architecture drives immune cell behavior. Not a systemic immune modulator
- Thymalin
- Thymic peptide bioregulation of T-cell differentiation
- Thymic restoration, T-cell maturation, immunosenescence reversal
- 5–10 mg per cycle, 5–10 day protocols
- 21–28 days at 2–8°C
- Direct thymic bioregulator. Only option for research requiring measurable thymopoiesis or thymic mass restoration
