Cosyntropin

Cortrosyn

A synthetic fragment of ACTH used to diagnose adrenal insufficiency. The standard test for evaluating adrenal function. Contains the first 24 amino acids of ACTH.

FDA Approved250 mcg IV/IM (standard) or 1 mcg IV (low-dose)
HormonalFDA Approved

Desmopressin

DDAVP

Synthetic vasopressin analog that selectively activates V2 receptors in kidneys, promoting water reabsorption.

FDA Approved10-40 mcg intranasal or 0.1-0.4 mg oral
HormonalFDA Approved

Eptifibatide

Integrilin

A cyclic peptide that inhibits platelet aggregation. Used during coronary interventions to prevent clot formation. Derived from a protein in pygmy rattlesnake venom.

FDA Approved180 mcg/kg IV bolus; 2 mcg/kg/min infusion
HormonalNot FDA Approved

Follistatin

FST

A naturally occurring protein that inhibits myostatin. Studied for muscle growth and dystrophy conditions.

Clinical Trials100-300 mcg daily
HormonalFDA Approved

Glucagon

GlucaGen

Life-saving treatment for severe hypoglycemia since the 1960s. Newer formulations include nasal spray (Baqsimi) and stable liquid (Gvoke).

FDA Approved1 mg IM/SC/IV or 3 mg intranasal (Baqsimi)
HormonalFDA Approved

Gonadorelin

GnRH

A synthetic version of gonadotropin-releasing hormone used diagnostically and therapeutically for reproductive conditions.

A neuropeptide that plays a critical role in initiating puberty and regulating the reproductive hormone axis.

Clinical Trials100-200 mcg subcutaneously once daily
HormonalFDA Approved

Lanreotide

Somatuline

A somatostatin analog that binds preferentially to SST2 and SST5 receptors for treatment of acromegaly and gastroenteropancreatic neuroendocrine tumors.

FDA Approved60-120 mg every 4 weeks
HormonalFDA Approved

Leuprolide

Lupron

A GnRH agonist suppressing testosterone and estrogen production, approved for prostate cancer, endometriosis, uterine fibroids, and precocious puberty.

FDA Approved7.5 mg monthly depot (common)
HormonalFDA Approved

Linaclotide

Linzess

A peptide activator of guanylate cyclase-C for irritable bowel syndrome with constipation and chronic idiopathic constipation, with localized gut action and minimal systemic uptake.

FDA Approved290 mcg daily (IBS-C) or 145 mcg daily (CIC)
HormonalPreclinical

MOTS-c

Mitochondrial ORF of the 12S rRNA type-c

A mitochondria-derived peptide that regulates metabolic homeostasis, discovered in 2015 and studied for insulin sensitivity, exercise capacity, and aging effects.

Animal Studies5-10 mg weekly
