What is triptorelin?
Triptorelin is a synthetic analogue of gonadotropin-releasing hormone (GnRH). It has the same ten amino acids as natural GnRH except at position 6, where glycine is replaced by D-tryptophan. This change makes it far more resistant to breakdown and more potent at the GnRH receptor than the natural hormone.

Triptorelin vs gonadorelin
Gonadorelin is the natural GnRH sequence, with glycine at position 6. Triptorelin swaps that glycine for D-tryptophan, which gives it a much longer action.
