British & Global Analytical Amino Acid & Peptide Register

BPC-157 is a stable 15-amino acid synthetic pentadecapeptide fragment originally derived from human gastric juice protein BPC. Evaluated in UK academic and biotechnology laboratories as an analytical benchmark for focal adhesion kinase (FAK) activation and endothelial tube formation assays.

TB-500 represents the synthetic active fragment of Thymosin Beta-4, a major physiological actin-sequestering protein. Studied in British biomedical research for its ability to regulate G-actin polymerization, promote keratinocyte migration, and downregulate myofibroblast differentiation.

Semax is a synthetic regulatory heptapeptide structurally derived from an adrenocorticotropic hormone fragment (ACTH 4-10) stabilized with a C-terminal Pro-Gly-Pro tripeptide. Examined in neuropharmacology laboratories for its modulation of BDNF, trkB receptors, and cerebral monoamines.

GHK-Cu is a naturally occurring tripeptide-copper coordinate complex identified in human plasma. Investigated in UK cosmetic chemistry and cellular biology laboratories for its regulation of matrix metalloproteinases, decorin, and collagen I/III biosynthesis.

CJC-1295 (Mod GRF 1-29) is a synthetic 29-amino-acid analogue of human growth hormone-releasing factor featuring four D-amino acid substitutions to enhance metabolic stability against dipeptidyl peptidase-4 (DPP-4). Evaluated in UK endocrine research for pulsatile somatotroph signaling.

Ipamorelin is a synthetic pentapeptide and selective ghrelin receptor (GHSR-1a) agonist. Distinct from earlier GHRPs due to its selectivity: it stimulates somatotroph growth hormone release in vitro without triggering substantial elevation in cortisol, prolactin, or ACTH.

AOD-9604 is a synthetic hexadecapeptide analog representing the lipolytic C-terminal domain of human growth hormone (hGH 177-191) with an added tyrosine residue. Investigated in UK metabolic and adipose tissue laboratories for beta-3 adrenergic receptor signaling without diabetogenic IGF-1 elevation.

Selank is a synthetic regulatory heptapeptide derived from the immunomodulatory tetrapeptide tuftsin, extended with a C-terminal Pro-Gly-Pro tripeptide. Examined in neuroimmunology laboratories for its allosteric modulation of GABAA receptors, enkephalinase inhibition, and IL-6 expression.

Epithalon (Epitalon) is a synthetic tetrapeptide modeled on the endogenous pineal extract epithalamin. Studied extensively in biogerontology laboratories for its ability to overcome the Hayflick limit via telomerase catalytic subunit (hTERT) transcription and chromatin remodeling.

MOTS-c is a 16-amino acid mitochondrial-derived peptide encoded within the mitochondrial 12S rRNA locus. Investigated in metabolic biology laboratories for its regulation of the folate-methionine cycle, direct activation of AMPK, and restoration of metabolic plasticity.

Tirzepatide is a synthetic 39-amino-acid unimolecular dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor co-agonist conjugated to a C20 fatty diacid moiety. Studied extensively in UK biochemical and pharmaceutical research for receptor affinity dynamics.

Semaglutide is a synthetic long-acting glucagon-like peptide-1 (GLP-1) receptor agonist modified at position 8 with alpha-aminoisobutyric acid (Aib) and acylated at Lys26 with a C18 fatty diacid chain. Studied in UK endocrinology and metabolic research as a classical mono-incretin reference standard.

KPV is a biologically active synthetic tripeptide (Lys-Pro-Val) representing the anti-inflammatory C-terminal sequence of alpha-melanocyte-stimulating hormone (alpha-MSH). Evaluated across European academic laboratories for mucosal cytoprotection, antimicrobial defense, and nuclear translocation.

PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (alpha-MSH) characterized by an intramolecular lactam bridge. Widely investigated across neurochemical laboratories as a selective agonist of central melanocortin MC3 and MC4 receptors.
