Bioregulator Peptides (Khavinson)
No lawful US pathway
01 · Overview
Bioregulator peptides are a class of short synthetic peptides, typically 2 to 4 amino acids in length, developed by Russian researcher Vladimir Khavinson based on sequences derived from organ-specific tissue extracts. Their proposed mechanism is that short peptides enter cell nuclei and interact with DNA and histones to regulate gene expression, a concept set out by the group in its own systematic review rather than established by independent structural work (PMID 34834147).
Examples include thymus-derived preparations (Thymalin), pineal preparations (Epithalamin), and short synthetic peptides such as Lys-Glu. The underlying hypothesis is that peptide bioregulators can slow aging by restoring tissue-specific patterns of protein synthesis (PMID 42839866).
02 · Research summary & key findings
Animal studies report that the pineal preparation Epithalamin increased mean lifespan in fruit flies, mice and rats and reduced mortality rate, effects the authors attribute partly to increased melatonin and reduced free-radical processes (PMID 9701766). A long-term clinical observation from the originating institutes reported improved health indices and lower mortality in people over 60 treated with Thymalin or Epithalamin, but it was not a blinded randomized trial and has not been independently replicated (PMID 14523363). Most of this literature comes from the same Russian research groups, international independent validation is lacking, and no Thymalin, Epithalamin or Vilon product appears in the FDA drug approval database.
03 · Regulatory status
Bioregulator Peptides (Khavinson) is in the investigational stage. While preclinical and early-phase data exist, it has not received regulatory approval for clinical use in the United States.
No lawful pathway today
Bioregulator Peptides (Khavinson) is not FDA-approved and does not currently have a lawful prescription or compounding pathway in the United States, so we do not sell it and will not book a consultation for it. That can change: in 2026 FDA began reviewing several peptides for compounding. If you are working on the goal it is studied for, a licensed clinician can tell you what is lawfully available, which may be something else.

Looking for a lawful, clinician-prescribed option for longevity and healthy ageing?
Bioregulator Peptides (Khavinson) is an investigational compound, is not FDA-approved, and has no lawful US compounding pathway, so we do not offer it and no clinician we work with will prescribe it. Products sold online as “research chemicals” are not made or tested to the standards required of medicines. If you are working on longevity and healthy ageing, a licensed clinician can tell you at a free consultation whether an FDA-approved or lawfully compounded treatment fits you, or whether nothing does.
