Pinealon vs Testagen
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Pinealon is a synthetic tripeptide (Glu-Asp-Arg) developed by the St. Petersburg Institute of Bioregulation, designed to penetrate the blood-brain barrier and exert neuroprotective, neurogenic, and anti-aging effects by regulating pineal gland and brain cell function.
- Testagen is a tetrapeptide bioregulator (Lys-Glu-Asp-Gly) developed by Professor Vladimir Khavinson, tissue-specific for the testes. It supports Leydig cell function, normalization of testosterone biosynthesis, and spermatogenic activity. Testagen is used in men's health protocols for age-related testosterone decline, male fertility support, and testicular anti-aging.
- Half-Life
- Short (peptides rapidly degraded), but epigenetic/gene regulatory effects persist
- Short (minutes); sustained gene-regulatory effects

- Typical Dose
- 5–10 mg (oral) or 50–100 mcg (SC)
- 10 mg per day
- Frequency
- Once daily for 10 days
- Daily for 10–30 days
- Key Benefits
- Neuroprotection against oxidative stress and hypoxia
- Promotes neuronal regeneration and repair
- Improves memory and cognitive function
- Enhances sleep quality via melatonin regulation
- Anti-aging effects on brain cells
- May slow cognitive decline in neurodegeneration
- Improves cerebrovascular circulation
- Reduces neuroinflammation
- Supports endogenous testosterone synthesis via Leydig cell normalization
- Promotes spermatogenesis and sperm quality
- Anti-aging effects on testicular tissue
- May attenuate age-related testosterone decline
- Mechanistically distinct from TRT — does not suppress HPG axis
- Useful adjunct to Gonadorelin and Kisspeptin-10 in male hormonal protocols
- Supports male fertility without exogenous hormone replacement
- Side Effects
- Excellent safety profile in clinical use
- Rare: mild drowsiness
- Transient mild headache at initiation
- Injection site reaction (SC)
- Generally well tolerated
- Mild injection site reactions
- No significant endocrine disruption reported at standard doses
