Modified GRF(1-29).
CJC-1295 without DAC (also known as Modified GRF 1-29) is a truncated GHRH analog with four amino acid substitutions for protease resistance, but without the albumin-binding DAC modification. Often studied alongside its DAC-modified counterpart to compare pulsatile vs. tonic GH stimulation. Supplied as research-grade material with 3rd-party HPLC verification and full Certificate of Analysis per lot.

Binds the GHRH receptor similarly to CJC-1295/DAC but without extended half-life. Published literature describes a pharmacokinetic profile closer to endogenous GHRH — a short pulse of GH release lasting on the order of 30 minutes to 2 hours.
Used in preclinical and research settings specifically when a pulsatile rather than sustained GH stimulation profile is desired. Often paired in research protocols with a GH secretagogue receptor agonist such as ipamorelin.

CJC-1295 (no DAC) is a 29-residue peptide with molecular formula C152H252N44O42 and molecular weight of approximately 3,358.9 Da.
The full structural data and release specifications are in the Compound Profile section above. Every lot ships with an independently verified Certificate of Analysis.
Each lot is independently verified by a 3rd-party analytical laboratory (STERIS Labs, Alcami Analytical, or equivalent) before release. Release specification is HPLC purity ≥ 99.5% (typical > 99.8%), mass spectrometry identity match within ±0.5 Da, water content < 5.0% Karl Fischer, and endotoxin < 0.25 EU/mL by LAL (USP <85>).

All compounds ship at ambient temperature in discreet, tamper-evident packaging. Lyophilized peptide powder is stable at room temperature for typical transit windows, which is why research-grade vendors ship this way. Tracked; signature not required.
Store unopened lyophilized product at 2–8°C protected from light. Once reconstituted, most peptides are stable at 2–8°C for approximately 28 days (compound-dependent).
Used in preclinical and research settings specifically when a pulsatile rather than sustained GH stimulation profile is desired. Often paired in research protocols with a GH secretagogue receptor agonist such as ipamorelin.
All PeptideBros compounds are sold strictly as chemical reference materials for in-vitro laboratory research. They are not for human consumption.
HPLC-verified. Mass-spec confirmed. Ambient-stable transit. The paperwork other vendors hope you never ask for.
