About Follistatin 344
Binds and neutralizes myostatin (GDF-8) and activin; removes the natural brake on muscle growth allowing supraphysiological hypertrophy
About GHRP-2
Synthetic hexapeptide that stimulates pulsatile growth hormone release from the anterior pituitary by acting on the ghrelin receptor (GHSR-1a). Commonly stacked with GHRH analogs such as CJC-1295 or Sermorelin to amplify GH output synergistically.

GHRP-2 stimulates GH and cortisol release. Research protocols measure IGF-1 for GH axis response and baseline cortisol given the compound's adrenal stimulation. Glucose markers are standard given GH's effect on insulin sensitivity.
GHRP-2
Corticosteroids
Research notes that GHRP-2 stimulates cortisol and ACTH release via the HPA axis. Combined use with corticosteroid medications may affect glucocorticoid regulation. Consult your prescriber before combining.
