What Is HCG?
Human Chorionic Gonadotropin (HCG) is a hormone that mimics Luteinizing Hormone (LH) in the body.
LH is the signal that tells the testes to:
- Produce testosterone
- Maintain testicular size and function
When SARMs suppress the HPTA, LH production drops, which can lead to:
- Reduced testosterone output
- Testicular inactivity or atrophy
- Slower post-cycle recovery
HCG works by directly stimulating the testes, even when the brain’s signaling is suppressed.
Why HCG Is Used With SARMs (Not Steroids)
With SARMs, suppression happens at the brain level, not because external testosterone replaces natural production.
In advanced cases, this creates a scenario where:
- The testes remain capable of producing testosterone
- But are not receiving LH signals
HCG temporarily bypasses the brain and keeps the testes active. This makes HCG a support tool, not a replacement for PCT.
When Gonadotropin Makes Sense After SARMs
HCG is typically considered when:
- The cycle involved highly suppressive SARMs (RAD-140, LGD-4033, YK-11)
- Multiple suppressive compounds were stacked
- The cycle was long or aggressive
- Preserving testicular function is a priority
In these cases, HCG may be used:
- On-cycle to prevent testicular shutdown
- Before or alongside PCT to improve recovery outcomes
When HCG Is NOT Necessary with SARMs
HCG is not required for:
- Mild SARMs cycles
- Non-hormonal compounds (MK-677, Cardarine, SR-9009)
- Beginner protocols
- Cycles where recovery is expected with SERMs alone
For most SARMs users, Nolvadex or Enclomiphene is sufficient.
How HCG Fits Into SARMs Recovery
Important distinction:
- HCG does NOT restart the HPTA
- SERMs (Nolvadex / Enclomiphene) do
HCG keeps the testes responsive, while SERMs restore the brain-to-testes signaling.
This is why HCG is never a replacement for PCT. It is used with or before proper PCT — not instead of it
Typical HCG Use in SARMs Context
HCG protocols are short, controlled, and precise.
Overuse can worsen suppression if mismanaged.
It is commonly paired with:
- Nolvadex
- Enclomiphene
- Clomid
Bloodwork should always guide usage.
