FPF 1070

Cerebrolysin is a mixture of neuropeptides and neurotrophic factors derived from porcine brain proteins. It mimics the actions of endogenous neurotrophic factors (NGF, BDNF, CNTF), promoting neuronal survival, synaptogenesis, and neuroplasticity. Approved in multiple countries for Alzheimer's disease, stroke recovery, and TBI, clinical trials show improvements in cognitive function, activities of daily living, and brain MRI outcomes.

GnRH · Gonadotropin-Releasing Hormone

Gonadorelin is a synthetic decapeptide identical to endogenous GnRH. When administered in pulsatile fashion it stimulates LH and FSH release from the pituitary, driving gonadal testosterone and estrogen production. Clinically used for diagnosing hypothalamic-pituitary dysfunction, treating hypogonadotropic hypogonadism, and inducing ovulation. Paradoxically, continuous administration causes receptor downregulation and hormonal suppression — the basis of GnRH agonist therapy in prostate cancer.

N-phenylacetyl-L-prolylglycine ethyl ester · GVS-111

Noopept is a dipeptide-derived nootropic approved in Russia for cognitive disorders and memory impairment. It is hydrolyzed in vivo to release cycloprolylglycine, an endogenous neuropeptide. Research demonstrates neuroprotective, memory-enhancing, and anxiolytic effects, upregulation of BDNF and NGF in the hippocampus and cortex, and potential benefits in Alzheimer's disease models. It is significantly more potent than piracetam on a weight-for-weight basis.

GHRH(1-29) · GRF 1-29 NH2

Sermorelin is a synthetic analog of the first 29 amino acids of endogenous growth hormone-releasing hormone (GHRH). It stimulates the pituitary to produce and secrete growth hormone in a pulsatile, physiologic manner. FDA-approved for GH deficiency in children, it is extensively researched in adults for body composition, sleep quality, and age-related GH decline.

SRIF · Somatotropin Release-Inhibiting Factor

Somatostatin is a 14-amino-acid cyclic peptide and the primary endogenous inhibitor of growth hormone secretion. It also inhibits insulin, glucagon, gastrin, cholecystokinin, and secretin release, slows GI motility, and reduces splanchnic blood flow. Its short half-life drove the development of longer-acting analogs (octreotide, lanreotide) used clinically for acromegaly, neuroendocrine tumors, and GI bleeding.
