Oxytocin- Summary
- Thymosin Beta-4 is an endogenous 43-amino acid peptide that is the primary intracellular actin sequestering peptide. It promotes tissue repair, reduces inflammation, regenerates hair follicles, and protects cardiac tissue. Closely related to TB-500 (the active fragment), it is used for systemic tissue recovery and anti-aging.
- Oxytocin is a 9-amino acid neuropeptide produced in the hypothalamus with diverse roles in social bonding, trust, stress reduction, and sexual function. Exogenous administration is used therapeutically to improve social cognition, reduce anxiety, and enhance intimacy.
- Half-Life
- Not well characterized; likely similar to TB-500 (~1–2 hours)
- ~3–5 minutes (IV); ~30–60 minutes (intranasal, CNS effects persist longer)
- Admin Route
- SubQ, IM
- Intranasal, SubQ, IV
