What differs between Ipamorelin and Tesamorelin
A five-residue synthetic amide against the full 44-residue GHRH amide with a trans-3-hexenoyl cap on its N-terminal tyrosine. The masses are 711.9 against 5,135.9, so nothing on a certificate could mix them up. Tesamorelin carries the native methionine and two deamidation-prone asparagines; ipamorelin has no methionine, tryptophan or cysteine to oxidise. Both are lyophilised powders in boxes of ten here, and the table below prints the per-milligram figure at every strength each is offered in. The two are not sold together in one vial: each is its own line.

Questions
What is the difference between Ipamorelin and Tesamorelin?
A five-residue synthetic amide against the full 44-residue GHRH amide with a trans-3-hexenoyl cap on its N-terminal tyrosine. The masses are 711.9 against 5,135.9, so nothing on a certificate could mix them up.
Is tesamorelin the whole GHRH chain?
Yes. GSRS names it (3E)-hex-3-enoylsomatoliberin (human): all 44 residues of human growth-hormone-releasing hormone, 32 to 75 of UniProt P01286, ending in leucine amide, with a trans-3-hexenoyl group on the amine of tyrosine 1. Ipamorelin is unrelated in sequence: five residues, Aib-His-D-2-Nal-D-Phe-Lys-NH2.
Which is larger and which more charged, ipamorelin or tesamorelin?
Tesamorelin weighs 4,424.0 more, 5,135.9 to 711.9, a little over seven times ipamorelin’s mass, and at 44 residues against five it is nearly nine times as long. Near neutral pH tesamorelin sits at about +4, with eight basic residues among its 44, and ipamorelin at about +2. Only tesamorelin has a capped N-terminus, the trans-3-hexenoyl group on tyrosine 1; ipamorelin starts from Aib, an amino acid outside the coded twenty.
Which is cheaper per mg, Ipamorelin or Tesamorelin?
Strength for strength, Ipamorelin costs less per mg at the two strengths both sell by the single box: at 5mg $0.764 per mg against $2.400 (IP5, TSM5), at 10mg $0.553 per mg against $2.258 (IP10, TSM10).
What are the molecular weights of Ipamorelin and Tesamorelin?
Ipamorelin’s calculated average mass is 711.9 g/mol and Tesamorelin’s 5,135.9 g/mol, 4,424.0 apart; in electrospray the ions come at m/z 712.9 (1+) for Ipamorelin against 1713.0 and 1285.0 (3+ and 4+) for Tesamorelin. On each certificate the measured mass is matched to the line’s calculated average mass, within about one unit, as how to read a peptide COA sets out.
Are Ipamorelin and Tesamorelin made to the same specification?
Yes: both are supplied to purity not less than 98.0 percent by RP-HPLC and net content within 5 percent of label, and each certificate reports those with a measured mass, matched to the calculated figure on each sheet. The retest date is on the batch record. What differs is each molecule’s own chemistry, described on its compound page.
