Complete HCG Protocol Guide for Post-Cycle Recovery
| Protocol Element | Details & Best Practices |
|---|---|
| Purpose of HCG in PCT | – Mimics LH (Luteinizing Hormone), directly stimulating the testes to produce endogenous testosterone. – Helps prevent or reverse testicular atrophy during or after steroid use. – Can bridge periods between cycle cessation and traditional SERM-based PCT (e.g., Clomid, Nolvadex). |
| When to Use | – During cycle (« on-cycle support »): Low-dose HCG can prevent shutdown and maintain testicular function. – Post cycle (beginning of PCT): Used to “prime” the testes before SERM therapy, especially after extended cycles or visible atrophy. – Not usually recommended during SERM phase or prolonged use (due to desensitization risk). |
| Standard HCG Dosing | – On-cycle support: 250–500 IU twice weekly – PCT “blast”: 1,000–2,000 IU every other day for 2–3 weeks (most common for severe suppression or atrophy) – Transition to SERM PCT: Stop HCG 3–4 days before starting Clomid/Nolvadex to avoid estrogen spikes. – Maximum duration: Use HCG for 2–3 weeks at a time to avoid Leydig cell desensitization. |
| Timing & Administration | – Begin HCG at least 5–10 days after the last steroid injection (for long-ester compounds), or 2–3 days after last oral/short ester. – Start SERM-based PCT (Clomid/Nolvadex) 3–4 days after last HCG injection. – HCG is administered via subcutaneous or intramuscular injection. Best injected on an empty stomach for consistency. |
