CJC-1295 No DAC: How to Find a Reliable Research Source
CJC-1295 No DAC — also known as Mod GRF 1-29 — is a 29-amino acid analog of growth hormone-releasing hormone (GHRH). It produces a short, pulsatile GH release, making it a common subject of research into GH secretion patterns. It is also a compound where sourcing quality matters more than average, because sequence accuracy is critical and errors are hard to detect without the right testing.
Why Sequence Accuracy Matters Here
CJC-1295 No DAC is a 29-amino acid chain. A single missed or substituted amino acid during synthesis can produce a compound that tests at high HPLC purity but is biologically inert or structurally incorrect. Mass spectrometry (MS) is the only test that catches this — it confirms the molecular weight matches the target peptide, verifying the sequence is right, not just that the sample is chemically clean. For CJC-1295 No DAC, an MS result is not optional. HPLC alone is not enough.
What to Look for in a CoA
- HPLC purity ≥98%
- MS molecular weight confirmation
- Batch number and test date
- Third-party lab name
The CoA should be a downloadable document specific to your batch — not a generic page shared across all products.
GMP Manufacturing
GMP-certified manufacturing ensures the synthesis environment is controlled and documented. For a compound as sequence-sensitive as CJC-1295 No DAC, this matters — it reduces the risk of incomplete synthesis or contamination that would not be visible in a purity score alone.
Studying CJC-1295 No DAC with Ipamorelin
CJC-1295 No DAC is most commonly studied alongside Ipamorelin, a GHRP (growth hormone-releasing peptide). The two compounds act on different but complementary receptor pathways — GHRH and ghrelin receptors respectively — and are often combined in research protocols to study their combined effect on GH pulse amplitude and frequency. Magnolia RL offers a combined CJC-1295 No DAC + Ipamorelin vial, eliminating the need to source and reconstitute the two compounds separately.
Storage and Reconstitution
Store lyophilized CJC-1295 No DAC at −20°C. Once reconstituted with bacteriostatic water, use within 4–6 weeks at 2–8°C. See our reconstitution guide for volume calculations and syringe selection.
