hCG (Human Chorionic Gonadotropin) is commonly used in bodybuilding during and after anabolic steroid cycles to help maintain natural hormone function. Anabolic steroids suppress the body’s production of luteinizing hormone (LH), which signals the testes to produce testosterone. hCG mimics LH, stimulating the testes directly and helping preserve their function.

During an Anabolic Cycle (On-Cycle Use)

When anabolic steroids suppress natural testosterone production, hCG can help prevent complete shutdown.

Key Benefits During Cycle:

Helps maintain testicular size

Supports continued natural testosterone signaling

May preserve fertility during longer cycles

Reduces severity of hormonal crash post-cycle

Helps maintain intratesticular testosterone levels

Low-dose hCG is sometimes used throughout a cycle to prevent long-term suppression rather than waiting until post-cycle recovery.

After an Anabolic Cycle (Pre-PCT Use)

After discontinuing anabolic steroids, natural testosterone production is often significantly suppressed. hCG may be used before starting Post Cycle Therapy (PCT) to stimulate the testes before introducing medications like SERMs.

Key Benefits Post-Cycle:

“Reactivates” testosterone production before PCT

Helps restore normal testicular function

May shorten recovery time
Supports sperm production recovery

Because hCG increases estrogen indirectly through testosterone conversion, monitoring and proper dosing are important to reduce risks such as gynecomastia or water retention
