What it is

Thymalin is a thymus peptide complex (from the Khavinson bioregulator program) studied for immune system support and healthy-aging research. It is one of the short peptide bioregulators with a Russian clinical tradition — a short-course injectable used to support immune function.

Evidence boundary

Registered clinical use in Russia; small clinical literature. Research use is limited to laboratory and education contexts.

Trial evidence

  • Russian clinical course is typically 10 mg intramuscularly daily for 5–10 days, repeated at intervals of several months.

Preparation and measurement

Reconstitution: 10 mg vial + 2 mL BAC = 5 mg/mL.

Concentration matches.

Titration rules

  • Standard use: 5–10 mg once daily.
  • Course length: 5–10 days, repeated every 1–6 months (common plan: twice a year).
  • Morning injection is a common convention for consistency; no stimulant effect, so evening also works.
  • Stable at room temperature in lyophilized form; refrigerate after reconstitution and use within a few days.
