Research Peptide Comparison
TB-500 is a synthetic peptide derived from Thymosin Beta-4, studied extensively in laboratory settings for its involvement in actin dynamics, cellular motility, and angiogenesis-related signalling cascades. Tesamorelin is a stabilised analogue of growth hormone-releasing hormone (GHRH) that binds selectively to pituitary GHRH receptors, making it a valuable research tool for investigating the somatotropic axis and growth hormone secretagogue pathways. The two peptides operate through fundamentally different mechanisms — TB-500 acting at the intracellular cytoskeletal level and Tesamorelin engaging G-protein-coupled receptor signalling upstream of GH release.
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 Tesamorelin 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 £21.00 less than Tesamorelin 5mg, it is the more affordable option in this comparison.
Tesamorelin is a synthetic analog of human growth hormone-releasing hormone (GHRH) modified at the N-terminus to confer resistance to enzymatic degradation and prolong receptor engagement. It is one of the more thoroughly characterised GHRH analogs in metabolic research, with literature focused on visceral adipose tissue reduction, IGF-1 dynamics and lipid-profile modulation.
Compared to TB-500 5mg, Tesamorelin 5mg is priced at £39.99 with 99%+ verified purity. Its CAS registry number is 218949-48-5. It has a molecular weight of 5135.90 g/mol.
Tesamorelin 5mg is available in 5mg, 10mg and ships with a full Certificate of Analysis from Janoshik Analytical. It is priced £21.00 higher than TB-500 5mg.
