Sermorelin
GHRH (1–29) research analog
How researchers describe Sermorelin
Acts on the pituitary GHRH-receptor (class-B GPCR), activating Gαs→cAMP→PKA cascades. Preclinical literature reports pulsatile somatotrope stimulation distinct from non-physiologic continuous receptor agonists.
- GHRH-R → Gαs → cAMP/PKA
- Somatotrope GH transcription
Lyophilized: −20°C. Reconstitution and stability are set by the end researcher; no use-window or dosing guidance is provided.
Per-lot HPLC + LC-MS tested
- HPLC + LC-MS laboratory analysis on every lot
