Research Peptide Comparison
Ipamorelin and TB-500 are among the most researched synthetic peptides in their respective categories, yet they differ substantially in molecular size, mechanism of action, and the biological processes they modulate. Ipamorelin is a compact pentapeptide that functions as a selective ghrelin receptor agonist to stimulate pulsatile growth hormone secretion from the anterior pituitary. TB-500 is a synthetic analogue of the naturally occurring protein Thymosin Beta-4, a 43-amino-acid peptide that binds G-actin to regulate cytoskeletal dynamics, and has been extensively studied in preclinical models for its roles in cellular migration, angiogenesis, and tissue remodelling.
Ipamorelin is a pentapeptide growth hormone-releasing peptide (GHRP) and selective agonist of the ghrelin (GHS-R1a) receptor. It is widely cited for its capacity to stimulate pituitary GH release without the cortisol, prolactin or aldosterone elevations associated with earlier GHRPs, making it a clean reference ligand in somatotropic and receptor-selectivity research.
Compared to TB-500 5mg, Ipamorelin 5mg is priced at £19.99 with 99%+ verified purity. Its CAS registry number is 170851-70-4. It has a molecular weight of 711.85 g/mol.
Ipamorelin 5mg is available in 5mg, 10mg and ships with a full Certificate of Analysis from Janoshik Analytical. It is priced £1.00 higher than TB-500 5mg.
TB-500 is a synthetic fragment of Thymosin Beta-4, a naturally occurring actin-sequestering peptide implicated in cellular migration, cytoskeletal remodelling and tissue regeneration. Research interest focuses on its capacity to upregulate actin polymerisation, modulate inflammatory cytokine profiles and influence anti-fibrotic signalling in cardiac, dermal and musculoskeletal models.
Compared to Ipamorelin 5mg, TB-500 5mg is priced at £18.99 with 99%+ verified purity. Its CAS registry number is 77591-33-4. It has a molecular weight of 4963.50 g/mol.
TB-500 5mg is available in 5mg, 10mg and ships with a full Certificate of Analysis from Janoshik Analytical. At £1.00 less than Ipamorelin 5mg, it is the more affordable option in this comparison.
