Overview
Modified GRF(1-29), commonly labeled "CJC-1295 without DAC," is a 29-amino-acid analogue of growth-hormone-releasing hormone carrying four substitutions on the sermorelin/GRF(1-29) backbone: D-Ala at position 2, Gln at 8, Ala at 15, and Leu at 27. The D-Ala2 substitution in particular is intended to resist dipeptidyl peptidase-4 cleavage. Unlike CJC-1295 with DAC, this molecule lacks the position-30 maleimidopropionyl-lysine, so it does not bind albumin and is comparatively short-acting.
In endocrine research it serves as a GHRH-receptor agonist tool for studying pulsatile growth-hormone release and GHRH-pathway signaling in cell and animal models, often in comparison with native GHRH(1-29) (sermorelin) and with the DAC-bearing analogue. The literature frequently and incorrectly equates "CJC-1295" with this no-DAC peptide; the exact backbone sequence is well defined, but reported molecular-formula and mass values differ across secondary sources, so those fields are omitted here pending a primary-source-confirmed value.
BioTech Pharma supplies this peptide as a lyophilized powder for laboratory research use only. It is not a drug and is not intended for human or veterinary use. Lot-specific analytical documentation may be available and should be confirmed for the applicable material. Bulk and custom-fill quantities are available by quote.

Analytical Data
Lot-specific documentation may be available for the applicable material and must be confirmed per enquiry. Where available, it may include:
- HPLC purity result
- LC-MS identity confirmation
- Appearance
- Net content
Request the records you need with your quote and we will confirm availability for your batch.
Procurement Details
Availability, lead time, salt / content basis, and cold-chain requirements depend on the specific lot and quantity, so we confirm them per enquiry rather than publishing fixed figures. Request confirmation for your requirements with your quote and our team will respond with details for the applicable batch.
Storage & Handling
Lyophilized: store desiccated at −20 °C, protected from light. Reconstituted: keep at 2–8 °C and establish working-solution stability empirically per lot, as prepared-solution stability depends on diluent, concentration, and handling.
