Sermorelin Off-Cycle GH-Axis Maintenance

Lower-intensity GHRH analog protocol for off-block maintenance.

Component peptides

The 29-amino-acid N-terminal fragment of endogenous growth-hormone-releasing hormone. Historically approved as Geref for paediatric growth-hormone-deficiency diagnostics.

Goal

Lower-intensity GHRH-analog protocol for off-block maintenance.

Peptides

Sermorelin

Why it works

The GHRH(1-29) analog aligns with the natural nocturnal GH pulse, providing lower-intensity somatotropic support between higher-effort training blocks.

How to use

Sermorelin — 100-300 mcg once daily subcutaneous, pre-bed.
