CJC-1295 For Sale USA — Research Grade Sourcing Guide 2026
CJC-1295 is the GHRH receptor agonist side of the most popular GH secretagogue stack — and one of the most frequently mislabeled compounds in the research peptide category, with CJC-1295 without DAC and Modified GRF (1-29) regularly confused or sold interchangeably.
CJC-1295 is one of the more confusing sourcing decisions in the GH-axis category — because "CJC-1295" as a label is applied to two meaningfully different compounds in practice: CJC-1295 with DAC (Drug Affinity Complex) and CJC-1295 without DAC (also called Modified GRF 1-29 or Mod GRF). They have dramatically different half-lives and pharmacokinetic profiles.
CJC-1295 With DAC vs Without DAC — Why It Matters for Sourcing
CJC-1295 with DAC incorporates a lysine-maleimide conjugate that enables irreversible albumin binding, extending the half-life to approximately 6-8 days. CJC-1295 without DAC (Mod GRF 1-29) has a half-life measured in minutes to hours. These are not interchangeable in research design — the pulsatile vs sustained GH release profiles they produce are completely different research conditions. As detailed in our CJC-1295 expanded guide, confirming which form you're sourcing is a prerequisite to any protocol design.
What the COA Should Confirm
For CJC-1295 with DAC, mass spectrometry should confirm the higher molecular weight consistent with the DAC modification (~3647 Da vs ~3367 Da for Mod GRF). A supplier selling either form without mass spectrometry data cannot confirm which compound is actually in the vial. This is the CJC-specific sourcing red flag that the standard HPLC-only COA fails to catch.
