Triiodothyronine, aka T3
Triiodothyronine, also known as T3, is a thyroid hormone. It affects almost every physiological process in the body, including growth and development, metabolism, body temperature, and heart rate. Bowen, R. (2010-07-24). “Physiologic Effects of Thyroid Hormones”. Colorado State
Calcitonin
Calcitonin is a 32 amino acid peptide hormone secreted by PARAFOLLICULAR CELLS (also known as C cells) of the thyroid (or endostyle) in humans and other chordates in the ultimopharyngeal body. It acts to reduce blood calcium (Ca2+), opposing the effects of PARATHYROID HORMONE (PTH). I
Corticotropin-like intermediate [lobe] peptide (CLIP)
Corticotropin-like intermediate [lobe] peptide (CLIP), also known as adrenocorticotropic hormone fragment 18-39 (ACTH(18-39)), is a naturally occurring, endogenous neuropeptide with a docosapeptide structure and the amino acid sequence Arg-Pro-Val-Lys-Val-Tyr-Pro-Asn-Gly-Ala-Glu-Asp-Glu
Melanin-concentrating hormone (MCH) aka PMCH
Melanin-concentrating hormone (MCH), also known as pro-melanin stimulating hormone (PMCH), is a cyclic 19-amino acid orexigenic hypothalamicpeptide originally isolated from the pituitary gland of teleost fish, where it controls skin pigmentation. Barson JR, Mo
Pro-opiomelanocortin (POMC)
Pro-opiomelanocortin (POMC) is a precursor polypeptide with 241 amino acid residues. POMC is synthesized in corticotrophs of the anterior pituitary from the 267-amino-acid-long polypeptide precursor pre-pro-opiomelanocortin (pre-POMC), by the removal of a 26-amino-acid-long signal pept
Oxytocin
Oxytocin (Oxt or OT) is a peptide hormone and neuropeptide normally produced in the hypothalamus and released by the posterior pituitary. Gray’s Anatomy: The Anatomical Basis of Clinical Practice (41 ed.). Elsevier Health Scienc

Prolactin receptor modulators
Prolactin Agonists An agonist is a chemical that activates a receptor to produce a biological response. Receptors are cellular proteins whose activation causes the cell to modify what it is currently doing. In contrast, an antagonist blocks the action of the agonist, while an inverse agoni
Prolactin (PRL)
In mammals, prolactin is associated with milk production; in fish it is thought to be related to the control of water and salt balance. Prolactin also acts in a cytokine-like manner and as an important regulator of the immune system. It has important cell cycle-related functions as a growth-, diffe
Gastrin-releasing peptide aka GRP and Pro-Gastrin-Releasing-Peptide aka Pro-GRP (and something called PreProGRP?)
Gastrin-releasing peptide, also known as GRP, is a neuropeptide, a regulatory molecule that has been implicated in a number of physiological and pathophysiological processes. Most notably, GRP stimulates the release of gastrin from the G cells of the stomach. Function G
Progastrin
Progastrin is an 80-amino acid intracellular protein and the precursor of gastrin, a gastrointestinal hormone produced by G cells in the gastric antrum. Fiona M., Gribble; Frank, Reimann; Geoffrey, P. Roberts (2018). Gastrointestinal Hormones. Physiology of the Gastrointestinal Tract, Else
Gastrin
Gastrin is a peptide hormone that stimulates secretion of gastric acid (HCl) by the parietal cells of the stomach and aids in gastric motility. It is released by G cells in the pyloric antrum of the stomach, duodenum, and the
