CJC 1295 5mg (No DAC) — Modified GRF 1-29
Native GHRH disintegrates in about seven minutes. DPP-IV enzymes clip it apart almost as fast as it can signal. CJC-1295 (No DAC) is the engineered answer — the same 1-29 amino acid GHRH fragment, but with four strategic substitutions at positions 2, 8, 15, and 27 that make it resistant to enzymatic degradation. The result: a half-life of 30 minutes to 2 hours instead of 7 minutes, without the sustained multi-day elevation that comes with DAC-modified variants. Buy CJC 1295 5mg

Mechanism
CJC-1295 binds GHRH receptors on pituitary somatotrophs, triggering adenylate cyclase, cAMP accumulation, PKA phosphorylation, and growth hormone vesicle release. The non-DAC form preserves pulsatile GH secretion patterns — closer to what endogenous GHRH produces — while the DAC version creates sustained, multi-day elevation. Published clinical data documents GH increases of 70-107% with IGF-1 elevations around 28% over 16-week observation periods (Khorram et al., JCEM, 1997; PubMed 9141541).
No DAC vs with DAC
The Drug Affinity Complex is a maleimidopropionic acid derivative that covalently binds serum albumin. With it: half-life jumps to 6-8 days, GH stays elevated constantly. Without it: half-life stays at 30 minutes to 2 hours, GH pulses naturally. Different tools for different research questions. Both available from Peptide Bio Sciences LTD.
CJC-1295 + Ipamorelin
These two target different arms of the GH axis — GHRH receptor vs GHS-R (ghrelin receptor). Preclinical protocols routinely pair them to study dual-pathway somatotroph activation. The CJC-IPA blend combines both in a single vial. Buy CJC 1295 5mg
