  1. Coy et al., JCEM 1994 (D-Ala2 GHRH(1-29)) — PMID 7962295

    IV infusion in 10 normal men: disappearance half-time 4.3 +/- 1.4 min for GHRH(1-29)-NH2 and 6.7 +/- 0.5 min for the D-Ala2 analogue, with MCR falling from 39.7 to 21 mL/kg/min. D-Ala2 is one of the substitutions in modified GRF(1-29), so the backbone clears in SINGLE-DIGIT MINUTES. No primary PK study of the full tetrasubstituted peptide exists, and the widely repeated 30 min figure has no published source and is not consistent with this data. Null rather than a fabricated number.
