Daily dosing holds steady levels. After the last dose, roughly 97% has cleared in ~6 days (five half-lives) — the window that matters for washouts, bloodwork and surgery.
What HCG is used for
- Mimics LH — maintains testicular function and fertility on TRT
- Restores testosterone production in restart protocols
- Supports libido and testicular volume
How it's typically used
TRT-support range: 250–500 IU subcutaneous 2–3× weekly.
What to watch for
- Can raise estrogen — may need an AI
- Overuse desensitizes the testes
- Prescription-only; monitor with bloodwork

Other other research compounds
Peptid AI is an educational and self-tracking tool — not a medical service, and not a vendor. Nothing here is medical advice, a prescription, or an endorsement. Doses reflect what is commonly reported in research literature; they are not recommendations. Many compounds listed are experimental, not approved for human use, and/or controlled substances that are illegal to possess without a prescription in many countries. Always consult a qualified physician before starting, changing, or stopping any protocol.
