CJC-1295 NO DAC (Mod GRF 1-29) 5mg

Research Grade

Mod GRF 1-29 — the tetra-substituted GHRH analogue that produces discrete physiological GH pulses without the sustained elevation of DAC, ideal for pulsatile GH research protocols.

Product Overview

CJC-1295 NO DAC (also designated Modified GRF 1-29 or Mod GRF 1-29) is a tetra-substituted 29-amino-acid analogue of GHRH(1-29) without the Drug Affinity Complex modification. The four amino acid substitutions (Tyr→His at position 1, Ala→Ala at position 2, Asp→Glu at position 8, and a structural stabilizing substitution at position 29) collectively improve metabolic stability and receptor binding affinity without extending half-life as dramatically as DAC. With a half-life of approximately 30–60 minutes, Mod GRF 1-29 produces discrete, physiological GH pulses when dosed, mimicking the natural GHRH burst pattern from the hypothalamus. This makes it a preferred compound for researchers seeking to preserve natural GH pulsatility.

preferred over the DAC version for me

if you want the short half life and want to dose pulsatile this is the version. 22EXO's mod-GRF is consistent.

good quality, fair price

Box was a little crushed

★★★☆☆

Outer cardboard had a corner dented. Vials inside were intact and the cold pack was still cold. Shipping carrier issue not 22EXO.

★★★★★

Purity at 98.9%. Short half-life confirmed in our PK studies. Exactly what we needed for pulsatile GH research.
