Frequently asked questions
Why was Sermorelin removed from the market?
The branded product Geref was voluntarily withdrawn by its manufacturer (EMD Serono) in 2008 for commercial reasons — not due to safety concerns. It remained available through compounding pharmacies, though the FDA has recently increased scrutiny of compounded peptides.
How is Sermorelin different from HGH injections?
Sermorelin stimulates your pituitary to produce its own growth hormone, preserving natural pulsatile release and feedback loops. Exogenous HGH bypasses the pituitary entirely, which can suppress your own production. Sermorelin produces more modest but more physiological GH elevation.
Is Sermorelin better than CJC-1295/Ipamorelin?
Sermorelin has a longer clinical history and was FDA-approved, giving it a stronger safety profile. CJC-1295 has a longer half-life and is often preferred for less frequent dosing. Ipamorelin works through a different receptor (ghrelin). Many clinics combine them. None are currently FDA-approved for anti-aging use.
