CJC-1295 with DAC FAQ: Reconstitution, Storage, Purity & Sourcing
3 min read•Published 2025-11-05•Quality Peptide USA Research
CJC-1295 with DAC is a modified 30-amino-acid GHRH analog incorporating a Drug Affinity Complex (DAC). The DAC chemistry forms a covalent bond with circulating albumin, dramatically extending the peptide's research half-life relative to native GHRH or sermorelin. This guide covers faq for researchers for CJC-1295 with DAC — written for laboratory researchers sourcing US-synthesized peptides from Quality Peptide USA.
Is CJC-1295 with DAC research-grade?
Yes. Every batch of CJC-1295 with DAC sold by Quality Peptide USA is released to a ≥ 99% HPLC purity specification, with mass-spec identity confirmation and LAL endotoxin testing on every lot. The certificate of analysis is published on the product page.
How should CJC-1295 with DAC be reconstituted?
Reconstitute CJC-1295 with DAC with bacteriostatic water (0.9% benzyl alcohol). Inject the water down the inside wall of the vial — do not inject directly onto the lyophilized cake. Swirl gently until fully dissolved. Refrigerate at 2–8°C after reconstitution.
What is the reported half-life?
≈ 6–8 days (research models) Half-life figures from in-vitro models are not directly transferable to ex-vivo or in-vivo systems.
Where is CJC-1295 with DAC synthesized?
CJC-1295 with DAC is synthesized in the United States and ships from a US facility. No overseas drop-shipping, no customs delays, full domestic cold chain.
What testing is performed on each batch?
RP-HPLC purity (≥ 99% spec), ESI / MALDI-TOF mass spectrometry, Karl Fischer water content, LAL endotoxin screen, and bioburden. All results are published on the per-batch certificate of analysis.
Can CJC-1295 with DAC be stacked with other peptides?
Many research protocols pair CJC-1295 with DAC with complementary peptides — the Glow stack for dermal models, the Wolverine stack for tissue repair, or GHRH/GHRP secretagogue blends for somatotropic studies. Review the published literature for your specific endpoint before designing a stacked protocol.
