PCT Stack — Post Cycle Research Bundle
Tamoxifen 20mg + Kisspeptin 10mg + HCG 5000IU

The Primal Edge PCT Stack brings together three of the most studied compounds in hormonal recovery research. Each one works at a different point in the body’s hormonal system — from the brain signals that start the process, all the way down to the glands that produce testosterone. Together they give researchers a complete picture of how the body’s hormone axis switches back on.

Bundle Components

Tamoxifen — 20mg
Tamoxifen blocks estrogen from attaching to its receptors in the brain and pituitary gland. When estrogen can’t send its “slow down” signal, the brain is free to restart its natural hormone output. It’s one of the most well-researched compounds for studying how estrogen feedback controls the hormonal system.

Key Benefits:
• Blocks estrogen’s braking effect on the hormonal system
• Helps the brain and pituitary restart natural hormone signalling
• Works at the feedback level — not at the glands directly
• Decades of research data across multiple study models

Kisspeptin — 10mg
Kisspeptin is the brain’s “on switch” for the entire reproductive hormone cascade. It signals the hypothalamus to release GnRH — the first domino in the chain that leads to testosterone production. Without this upstream signal, the rest of the system stays quiet.

Key Benefits:
• Triggers the very first step in the hormone recovery chain
• Restarts the brain’s natural signalling before the pituitary and gonads respond
• Ideal for studying how the hormonal system wakes back up after suppression
• Works higher up the chain than HCG or Tamoxifen — making it a unique research tool

HCG — 5000IU
HCG mimics LH — the hormone the pituitary normally sends to the testes to produce testosterone. By binding directly to the same receptor, HCG can stimulate testosterone production at the gonadal level even when the pituitary isn’t yet sending its own signal.

Key Benefits:
• Directly stimulates the testes without needing pituitary involvement
• Keeps gonadal function active during periods of hormonal suppression
• Studies how the testes respond when LH-like signals are reintroduced
• One of the most extensively researched gonadotropin compounds available

Why This Stack?
These three compounds hit every level of the hormonal system at once:
• Kisspeptin — restarts the brain signal (hypothalamus)
• HCG — directly stimulates the testes (gonads)
• Tamoxifen — removes the estrogen brake (pituitary/hypothalamus feedback)

That’s what makes this stack a benchmark combination for HPG axis recovery research.
