protirelin
Hypothalamic tripeptide. Thyroid and prolactin axis research; clinical context tracking.
- Half-life
- 6 min
- Out of system
- ~1 h
- Route
- Subcutaneous
- Level
- Intermediate
Very short-acting — protocols dose 1–2× a day. After the last dose, roughly 97% has cleared in ~1 h (five half-lives) — the window that matters for washouts, bloodwork and surgery.
