What differs between Gonadorelin and Triptorelin
The native GnRH decapeptide against its D-tryptophan-6 analogue. One residue differs, and it adds 129 mass units and a second tryptophan, so triptorelin has more that can oxidise. That D-tryptophan is the only D-residue in either chain. Both begin with pyroglutamate and end with glycinamide. The list prices them as separate lines; the per-milligram comparison is below.

Questions
What is the difference between Gonadorelin and Triptorelin?
The native GnRH decapeptide against its D-tryptophan-6 analogue. One residue differs, and it adds 129 mass units and a second tryptophan, so triptorelin has more that can oxidise.
Which is cheaper per mg, Gonadorelin or Triptorelin?
At 2mg, the only strength both are offered in, Gonadorelin is the cheaper per mg: $1.310 per mg against $1.403 (GND2 in 50-box lots, TA/G2 in 50-box lots).
What are the molecular weights of Gonadorelin and Triptorelin?
Gonadorelin’s calculated average mass is 1,182.3 g/mol and Triptorelin’s 1,311.5 g/mol, 129.2 apart; in electrospray the ions come at m/z 1183.3 and 592.2 (1+ and 2+) for Gonadorelin against 1312.5 and 656.7 (1+ and 2+) for Triptorelin. 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 Gonadorelin and Triptorelin 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.
