Tesamorelin vs PT-141 Bremelanotide: research peptide comparison (UK)
Tesamorelin 10 mg compared with PT-141 Bremelanotide 10 mg for UK laboratory supply: identity, documentation, storage, and how Solent lists both. Research use only.
Two defined materials
Tesamorelin and PT-141 Bremelanotide are separate catalogue entries. A synthetic growth-hormone-releasing hormone (GHRH) analogue studied in research into GHRH-receptor signalling, the GH axis and metabolic pathways in experimental models. A synthetic melanocortin-receptor agonist studied in research into MC4R signalling pathways in experimental models. Neither is a licensed medicine. Solent does not recommend one over the other for any biological effect — choose by the protocol you have written.
Tesamorelin
Tesamorelin 10 mg is listed under gh axis. CAS 218949-48-5. Purity ≥ 99% (HPLC). Packed as lyophilised powder and dispatched from Southampton.
