CJC-1295 (no DAC)
Short-acting GHRH analogue for pulsatile growth hormone release research.
Class
GHRH analogue
Half-life
~30 min
Studied in
Endogenous GH release, paired with ghrelin mimetics.
What it is
CJC-1295 without DAC, also known as Mod GRF (1-29), is a tetra-substituted GHRH(1-29) analogue with improved enzymatic stability while retaining a short half-life suitable for pulsatile GH release studies.
Mechanism studied
Stimulates anterior pituitary GHRH receptors for short GH pulses.
Research notes
- Often co-administered with ipamorelin in research protocols.
Before sourcing any material
- Confirm a lot-matched third-party certificate of analysis (HPLC purity and mass-spectrometry identity).
- Check the stated peptide content per vial, not just the gross vial mass.
- Plan reconstitution volumes first so the vial size matches your protocol.
- Verify what is lawful in your jurisdiction — these are in-vitro research reagents, not medicines.
