====== HCG Protocols ====== **Human Chorionic Gonadotropin (hCG)** is a peptide hormone structurally similar to luteinizing hormone (LH). In men, it stimulates the Leydig cells of the testes to produce testosterone. For steroid users, hCG is commonly used to: * Prevent or reverse testicular atrophy during a cycle * Maintain fertility * Support recovery of the hypothalamic-pituitary-testicular axis (HPTA) * Prime the body for effective post-cycle therapy (PCT) ===== What Is hCG? ===== * Mimics the action of **LH**, signaling the testes to produce testosterone and sperm * Biologically active in males despite being a hormone found in pregnant women * Available as prescription medication or under research chemical (RC) labels ===== Why Use hCG? ===== **AAS use suppresses natural LH/FSH**, causing the testes to shut down testosterone and sperm production. Consequences may include: * Shrinking of testicles (testicular atrophy) * Reduced libido * Low energy and mood * Long-term fertility suppression Using hCG **during or immediately after** a cycle can: * Keep testes functioning * Improve response to PCT SERMs * Shorten recovery time ===== Common HCG Protocols ===== ^ Protocol Type ^ Timing ^ Dose Range ^ Frequency ^ Notes ^ | On-Cycle Support | During entire AAS cycle | 250–500 IU | 2–3x per week | Maintains testicular function and responsiveness | | Pre-PCT Priming | Final 2–4 weeks of cycle | 500–1,000 IU | 2–3x per week | Helps restore size and baseline testicular function before PCT begins | | Blast Protocol | Final 1–2 weeks before PCT | 1,000–2,000 IU | EOD (Every Other Day) | Aggressive stimulation to reverse testicular atrophy | | Low Dose TRT Maintenance | Long-term TRT use | 250 IU | 2x per week | Used by some to retain fertility on TRT | **Note:** Higher doses (>2,000 IU) may desensitize LH receptors. Always use the minimum effective dose. ===== Mixing and Storage ===== * hCG comes as a lyophilized (freeze-dried) powder and must be reconstituted with **bacteriostatic water** * After mixing: - Store refrigerated (2–8°C / 35–46°F) - Stable for 30–60 days * Use insulin syringes (29–31G) for SubQ injection ===== SubQ vs IM Administration ===== * **SubQ (subcutaneous)** injection is preferred - Less painful - Slower absorption but equally effective * **IM (intramuscular)** also works, but unnecessary for most users ===== PCT Integration ===== hCG is not a replacement for SERMs (e.g., Nolvadex or Clomid), but it can **enhance** PCT if used strategically. Best practices: * Do **not** use hCG during SERM-based PCT * Use **prior to** starting PCT to "prime" the testes * After stopping hCG, begin PCT with SERMs 3–5 days later Recommended sequence: - Cycle ends - Run hCG for 2–4 weeks (500–1,000 IU, 3x/week) - Stop hCG - Wait 3–5 days - Begin SERM PCT (e.g., Nolva + Clomid) ===== Real-World Bodybuilder Insights ===== From the r/steroids community and Steroid Wiki PDF: * “If you’ve ever had marble-sized balls on PCT, you didn’t use hCG correctly.” * “250 IU twice per week on cycle = perfect sweet spot. No shrinkage.” * “Never run hCG with your SERM. You’ll confuse the HPTA and stall recovery.” * “Don’t wait until after cycle to fix shutdown. Prevention is always better.” ===== Bloodwork and Monitoring ===== To monitor HCG effectiveness: * Check **Total Testosterone**, **LH**, **FSH**, and **Estradiol (sensitive assay)** * Look out for signs of excess estrogen: - Bloating - Gyno - Mood swings **Tip:** hCG can raise E2 due to increased testosterone → aromatization. Be prepared to use a low-dose **AI** (e.g., 0.25 mg Arimidex 2x/week) if symptoms arise. ===== Summary ===== * hCG mimics LH and stimulates natural testosterone production * Use during or shortly after a cycle, but **not during SERM PCT** * Helps preserve testicular size and function * Improves response to PCT * Store properly and avoid overuse to prevent desensitization Properly timed hCG use can dramatically improve hormonal recovery, fertility, and quality of life after a cycle.
