Follistatin 344 and Sermorelin target different goals — Follistatin 344 for myostatin and activin A neutralization — dual TGF-β inhibition, Sermorelin for pulsatile GH release via direct GHRH receptor agonism at the pituitary. They're compared here for reference, not as direct substitutes.

About Follistatin 344
Binds and neutralizes myostatin (GDF-8) and activin; removes the natural brake on muscle growth allowing supraphysiological hypertrophy
About Sermorelin
Sermorelin is a synthetic analogue of the first 29 amino acids of endogenous growth hormone-releasing hormone (GHRH). It binds to GHRH receptors on pituitary somatotrophs, stimulating pulsatile GH secretion in a physiological pattern that preserves the natural hypothalamic-pituitary feedback axis — contrasting with direct GH administration. Downstream IGF-1 elevation mediates many of its body composition, tissue-repair, and sleep quality effects.

Sermorelin clinical protocols measure IGF-1 as the primary marker of GH axis response. Fasting glucose and insulin are standard baseline assessments given GH's effect on insulin sensitivity.
Sermorelin
Ipamorelin
Research suggests Sermorelin and Ipamorelin may produce complementary growth hormone release effects when combined. Sermorelin acts as a GHRH analogue via pituitary receptors, while Ipamorelin acts via ghrelin receptors — dual-pathway stimulation studied in GH optimization research.
