Growth Hormone
CJC-1295 w/ No DAC
5mg / vial
A synthetic 30-amino-acid GHRH(1–29) analog without Drug Affinity Complex modification, producing shorter, more pulsatile growth hormone release. Studied for transient GHRH receptor activation on pituitary cells, mimicking natural GH secretion patterns, and GH/IGF-1 profiles in animal models. Frequently combined with GHRPs such as Ipamorelin to examine synergistic effects on GH pulse frequency and amplitude.

Areas of Investigation
Research Applications
GH Release
Pulsatile GH Release
Studied for producing shorter, more pulsatile growth hormone release that closely mimics natural GHRH secretion patterns, allowing time-specific GH stimulation windows.
IGF-1
IGF-1 Axis Research
Investigated for transient IGF-1 elevations through pulsatile GH stimulation, supporting downstream anabolic and regenerative signaling research.
Synergy
Combination GH Axis Studies
Frequently combined with ipamorelin or other GHRPs to examine synergistic GH pulse amplitude and frequency through dual, non-competing mechanisms.
Selectivity
Selective Endocrine Signaling
Researched for selective GHRH receptor activation without the sustained baseline elevation associated with DAC-modified analogs — preferred in protocols requiring physiological GH kinetics.

Protocol
Storage & Handling
Long-Term Storage
Store lyophilized peptide at −20°C. Under these conditions the product remains stable for up to 24 months from the date of manufacture.
After Reconstitution
Once reconstituted, store at 4°C and use within 30 days. Avoid repeated freeze-thaw cycles as this may degrade compound integrity.
Shipping Conditions
All orders ship in insulated packaging with cooling packs to maintain the cold chain during transit. Free on every order, no minimum required.

Frequently Asked Questions
CJC-1295 w/ No DAC is also referred to as Modified GRF(1-29) or Mod GRF 1-29. It is a stabilized 29-amino-acid GHRH analog with amino acid substitutions that resist enzymatic degradation, extending its half-life to approximately 30 minutes — significantly shorter than the DAC version but longer than native GHRH.
No DAC is preferred when protocols require pulsatile GH release that more closely mimics physiological GHRH patterns. The shorter half-life allows for more controlled, time-specific GH stimulation windows. DAC is preferred for studies requiring sustained, prolonged GH/IGF-1 elevation without frequent administration.
In preclinical research settings, many researchers combine them in the same vial for convenience. Both are stable in bacteriostatic water and are chemically compatible. Ensure the combined reconstitution volume is calculated correctly for your desired concentration of each compound.
Add bacteriostatic water slowly along the vial wall, gently swirl until dissolved. Do not shake. Use our Reconstitution Calculator for precise volume guidance.
Our CJC-1295 w/ No DAC is verified at ≥98% purity via third-party HPLC analysis. The current batch is confirmed at 99.1% by Apex Analytics Lab. A full COA ships with every order.
