What drives the Tesamorelin price
Tesamorelin is a forty-four-residue peptide carrying an N-terminal trans-3-hexenoyl group, with the formula C221H366N72O67S and a molecular weight of 5135.9 g/mol. At this length it is among the longest chains in the index, and each additional residue lowers the yield of full-length product. The hexenoyl cap is added on the resin after the final coupling, a short extra step, but it shifts the HPLC retention of the product and has to be confirmed by mass spectrometry. Long chains also carry more deletion by-products, so preparative purification takes more passes to reach release purity. Supply is thinner than for the short fragments, and most listings are 5 mg or 10 mg vials. The two bands sit close together per mg, a sign that synthesis cost, rather than vial filling, dominates the price of this compound. A tesamorelin listing far below the band medians is the exception in this market, not the rule.
