DDAVP · 1-desamino-8-D-arginine vasopressin

Desmopressin (DDAVP) is a synthetic vasopressin analog modified to eliminate vasopressor activity while retaining antidiuretic potency. FDA-approved for central diabetes insipidus, nocturnal enuresis (bedwetting), and von Willebrand disease, it achieves selective V2 receptor activation. Research explores its role in cognitive enhancement, where intranasal administration shows effects on memory consolidation.

Afamelanotide · Scenesse

Melanotan I (afamelanotide) is a linear synthetic α-MSH analog with higher selectivity for MC1R than MT-II. FDA-approved as Scenesse for erythropoietic protoporphyria (EPP), where it reduces phototoxic pain by enhancing melanin production and UV protection. Research explores broader applications in vitiligo, polymorphous light eruption, and other photosensitive disorders.

Sandostatin · SMS 201-995

Octreotide is a synthetic 8-amino-acid somatostatin analog with a much longer half-life than native somatostatin. FDA-approved for acromegaly, carcinoid syndrome, VIPomas, and variceal bleeding, it is also used off-label for Cushing's disease, thyroid cancer, and refractory diarrhea. Long-acting release (LAR) formulations allow monthly dosing. It is among the most clinically important peptide drugs in endocrinology.

Symlin · synthetic amylin

Pramlintide is a synthetic analog of amylin, a peptide co-secreted with insulin from pancreatic β-cells. Approved as adjunct therapy to insulin in type 1 and type 2 diabetes, it slows gastric emptying, suppresses postprandial glucagon, and promotes satiety. It is the only amylinomimetic approved for clinical use and is studied for its complementary role to insulin in postprandial glucose control.

Selanc · TP-7

Selank is a synthetic heptapeptide analog of tuftsin developed by the Russian Institute of Molecular Genetics. Approved in Russia for anxiety and cognitive disorders, it exhibits anxiolytic effects comparable to benzodiazepines without sedation or dependence. Research shows it modulates GABA, serotonin, and dopamine systems, enhances BDNF expression, and improves memory consolidation and learning.

C₃₃H₅₇N₁₁O₉ · 751.87 Da

MEHFPGP · Pro8-Gly9-Pro10-ACTH(4–10)

Semax is a synthetic heptapeptide analog of ACTH(4-7) developed in Russia, where it is approved for stroke, TBI, peptic ulcers, and cognitive enhancement. It upregulates BDNF and its receptor TrkB, promotes dopamine and serotonin turnover, and has demonstrated neuroprotective effects in ischemia models. Research highlights improvements in attention, memory, and recovery from neurological injury.

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.

C₁₄₉H₂₄₆N₄₄O₄₂S · 3357.88 Da

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.

Egrifta · TH9507

Tesamorelin is a stabilized synthetic GHRH analog FDA-approved for reduction of excess abdominal fat in HIV-infected adults with lipodystrophy. It stimulates pulsatile GH secretion while preserving natural feedback regulation. Research demonstrates significant visceral adipose tissue reduction, improved lipid profiles, and cognitive benefits, making it a key study compound for metabolic dysfunction.

Thyrotropin-Releasing Hormone · Thyroliberin

TRH is a tripeptide (pGlu-His-Pro-NH2) produced in the hypothalamus that stimulates TSH and prolactin release from the anterior pituitary. Beyond thyroid regulation, TRH has direct CNS effects — it is alerting, antidepressant, neuroprotective, and anticonvulsant. Research explores TRH analogs (taltirelin, approved in Japan) for ALS, spinal cord injury, Alzheimer's disease, and treatment-resistant depression, avoiding thyroid side effects.
