Practical Considerations# Availability# Bioregulator peptides have variable availability: Thymalin is registered as a pharmaceutical product in Russia and available through Russian pharmacies Epitalon was available as a research peptide from compounding pharmacies in the US until 2024, when it was placed on FDA Category 2 (banned from compounding) Vilon and Pinealon are less commercially available, primarily sourced through specialized research peptide suppliers Administration Routes# Epitalon: Typically subcutaneous injection in research protocols Thymalin: Intramuscular injection (standard Russian medical protocol) Vilon: Subcutaneous injection or intranasal (limited data on oral bioavailability) Pinealon: Intranasal or sublingual delivery proposed for CNS targeting, subcutaneous injection in animal studies Safety Profile# Bioregulator peptides have generally favorable safety profiles in published research: No significant adverse effects reported across decades of study Small molecular size reduces immunogenicity risk Cyclic dosing limits cumulative exposure Thymalin has the longest safety track record through decades of Russian clinical use Theoretical concern about unintended gene regulation effects, though no evidence of this has been reported Conclusion# The Khavinson bioregulator peptides represent one of the most ambitious and controversial areas of anti-aging research
