Results from this study4

No result from this study comes from a test of the peptide.

Studies that did not test the peptide alone4

In this study, Triptorelin (Trelstar, Decapeptyl) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Triptorelin (Trelstar, Decapeptyl).
