Overview of Peptide Categories
Research peptides can be broadly categorised based on their primary mechanisms of action and research applications. Understanding these categories helps researchers select appropriate compounds for their specific areas of study.
Growth Hormone Secretagogues
Growth hormone secretagogues (GHS) are peptides that stimulate the release of growth hormone from the pituitary gland. They work through two main mechanisms:
GHRH Analogues: These peptides mimic Growth Hormone Releasing Hormone. CJC 1295 (with and without DAC) is the most widely studied example. It stimulates GH release through the GHRH receptor pathway.
Ghrelin Mimetics: These peptides activate the ghrelin receptor (GHS R1a). Examples include Ipamorelin, GHRP 2, GHRP 6, and Hexarelin. They stimulate GH release through a pathway complementary to GHRH.
Combination Approach: Research often combines a GHRH analogue with a ghrelin mimetic (such as CJC 1295 plus Ipamorelin) for synergistic GH release.
Healing and Repair Peptides
This category includes peptides studied for their tissue repair and regenerative properties:
BPC 157: Derived from gastric juice, studied for gastrointestinal protection and multi tissue repair.
TB 500 / Thymosin Beta 4: Regulates actin polymerisation and promotes cell migration for wound healing.
Pentadecarginine: A newer compound studied for wound healing applications.
GLP 1 and Metabolic Peptides
The fastest growing category in peptide research:
Semaglutide: Long acting GLP 1 receptor agonist
Tirzepatide: Dual GIP/GLP 1 receptor agonist
Retatrutide: Triple GIP/GLP 1/Glucagon receptor agonist
AOD 9604: Growth hormone fragment studied for metabolic effects
Nootropic and Neuroprotective Peptides
Peptides studied for cognitive and neurological effects:
Selank: Synthetic analogue of tuftsin, studied for anxiolytic and nootropic properties
Semax: Synthetic ACTH analogue, studied for neuroprotective and cognitive effects
DSIP: Delta Sleep Inducing Peptide, studied for sleep regulation
Dihexa: Studied for cognitive enhancement through HGF/MET pathway
Anti Aging and Longevity Peptides
Epithalon: Synthetic version of epithalamin, studied for telomerase activation
GHK Cu: Copper peptide studied for skin remodelling and wound healing
NAD+: While technically a coenzyme, NAD+ precursors are studied for cellular energy and longevity
MOTS c: Mitochondrial derived peptide studied for metabolic regulation
Cosmetic Peptides
Snap 8: Studied for its effects on muscle contraction related to expression lines
GHK Cu: Also falls into this category for its skin related research applications
Sexual Health Research Peptides
PT 141 (Bremelanotide): Melanocortin receptor agonist studied for sexual function
Kisspeptin: Studied for its role in reproductive endocrinology
Conclusion
The diversity of peptide categories reflects the breadth of biological processes they influence. As research continues to expand, new categories and subcategories will emerge, further enriching this dynamic field.
