About the compound

Modified GRF 1–29 carries four amino-acid substitutions that extend the half-life of the native GHRH fragment while retaining receptor activity. The no-DAC version lacks the maleimide linker used for albumin conjugation.

Supplied as a lyophilized powder in 5 mg and 10 mg vials.
