GHRH/GH-Axis

CJC-1295 No DAC Research Peptide

CJC-1295 No DAC (also known as Mod GRF 1-29) is the non-conjugated form of CJC-1295. Without the Drug Affinity Complex linker, it has a much shorter half-life, research uses it to study sharper, more pulsatile GHRH receptor activation patterns versus the extended profile of CJC-1295 with DAC.

CJC-1295 No DAC in Research

CJC-1295 No DAC — also catalogued in the literature as Mod GRF 1-29 — is the unconjugated form of the CJC-1295 GHRH analog. Without the albumin-binding linker its half-life is short, producing the pulsatile receptor activation profile that more closely mirrors endogenous GHRH release in animal models.

Supplied lyophilized at 5mg and ≥99% HPLC purity, independently verified per batch. It is the standard comparator to the DAC-conjugated version, and is frequently studied alongside the ghrelin-receptor agonist Ipamorelin in dual-pathway secretagogue research.

Research Overview

  • Investigated for short-acting GHRH receptor activation
  • Studied for pulsatile GH release that more closely mimics endogenous patterns
  • Research into combined administration with GH secretagogues (e.g. ipamorelin)
  • Preclinical pharmacokinetic comparisons against DAC-conjugated CJC-1295
  • Explored for GH/IGF-1 axis modulation without sustained receptor saturation

Quality & Testing

Every CJC-1295 No DAC batch is verified by independent third-party HPLC and mass-spectrometry testing, with a batch-specific certificate of analysis available on the COA page.

Laboratory Handling & Storage

Lyophilized peptides are supplied as a freeze-dried powder and are most stable stored cold (2–8°C), protected from light and moisture, in the original sealed vial. Under these conditions the research literature generally reports multi-year integrity for dry peptide material.

Once reconstituted in a laboratory setting, solutions are typically stored refrigerated and used within the window appropriate to the diluent and compound; repeated freeze–thaw cycles are avoided because they can promote aggregation. See our research overview on reconstitution and lyophilization for the underlying formulation science.

Frequently Asked Questions

Is CJC-1295 No DAC the same as Mod GRF 1-29?

Yes — the two names refer to the same tetrasubstituted GHRH(1-29) analog. 'No DAC' distinguishes it from the albumin-conjugated long-acting version.

Why pair it with Ipamorelin in research?

They act on complementary receptors: this compound on the GHRH receptor and Ipamorelin on the ghrelin receptor (GHS-R1a). Dual-pathway designs use the pair to study additive secretagogue signaling in models.

Is CJC-1295 No DAC for human use?

No. It is supplied strictly for laboratory research and is not for human consumption or any medical application.
