Half-life: - time for plasma concentration to fall by 50%.
GHRH: - hypothalamic peptide that stimulates pituitary GH release.
GHRP: - growth-hormone-releasing peptide; ghrelin-receptor agonist class.
GLP-1: - incretin hormone; agonists studied for glycaemic / weight outcomes.
GIP: - incretin co-targeted with GLP-1 in dual agonists.
IGF-1: - primary mediator of GH effects on tissue.
mTOR: - central kinase regulating protein synthesis and autophagy.
AMPK: - energy sensor activated when cellular ATP is low.
Sirtuin: - family of NAD+-dependent deacetylases (SIRT1 to 7).
NAD+: - coenzyme central to redox biology and sirtuin activity.
Lyophilized: - freeze-dried; standard form for peptide storage.
Reconstitution: - adding bacteriostatic water to dissolve a lyo vial.
BAC water: - bacteriostatic water; 0.9% benzyl alcohol preservative.
HPLC: - high-performance liquid chromatography purity assay.
NMR: - spectroscopic identity test for peptide structure.
COA: - certificate of analysis; per-batch identity / purity report.
CAS: - Chemical Abstracts Service registry number.
Subcutaneous (SC): - injection into the fatty layer beneath the skin.
Intramuscular (IM): - injection into muscle tissue, deeper than SC.
Intranasal (IN): - mucosal route; common for short peptides.
Pharmacokinetics: - how the body processes a substance (ADME).
Pharmacodynamics: - the biological effect a substance produces.
Bioavailability: - fraction of dose reaching systemic circulation unchanged.
Agonist: - binds a receptor and triggers its biological response.
Antagonist: - binds a receptor and blocks its normal response.
Receptor: - protein that binds a ligand to trigger a cellular response.
Ligand: - molecule that binds a receptor with specificity.
Endogenous: - originating from within the organism.
Exogenous: - originating from outside the organism (administered).
Research-use only: - sold for laboratory / in-vitro research; not for administration.
