THE GH SUSTAINER
CJC-1295 DAC, GRF (1-29) analog with DAC, CJC-1295 w/ DAC
CJC-1295 with DAC (Drug Affinity Complex) binds to albumin in your blood, extending its half-life to about a week. That means just 1-2 injections weekly produce sustained growth hormone elevation. That's convenient, but the steady GH bleed is less physiologic than the pulsatile pattern your body produces naturally.

No. This profile records CJC-1295 (with DAC) as not FDA approved and for research use only.
Review the regulatory and source details on this page for the current context.
Dose: 1-2 mg per week (typically split into 2 doses).
Schedule: twice_weekly. Cycle: 8 weeks on, 8 weeks off. This is clinical-team guidance for reference and does not replace individualized instructions from a licensed clinician.

Review the CJC-1295 (with DAC) research sourcesReported side effects of CJC-1295 (with DAC) include Flushing, Injection site irritation, Water retention, Joint pain, and Fatigue.
They are reported or occasional reactions, not a prediction of what any one person will experience.
CJC-1295 (with DAC) has an editorial safety grade of B (Good Safety).
Generally well-tolerated but the sustained GH elevation can cause more water retention and joint pain than pulsatile dosing. Safety depends on dose, sourcing, health history and medical supervision, so this page does not call it safe for personal use.
ConjuChem researchers described CJC-1295 in 2005 as a modified human growth-hormone-releasing factor analogue. Its design combines four substitutions in the 1-29 peptide with an additional C-terminal lysine bearing a reactive maleimide group. That group was designed for covalent attachment to serum albumin. It is the chemical feature relevant to this catalog's with-DAC entry.

Market evidence
We found certificates from some of the CJC-1295 (with DAC) vendors we track. Based on the certificates our crawler found; vendors may publish more than we index. Research on this page describes the molecule. Vendor certificates concern particular market samples or batches; they do not change the research evidence or establish clinical safety, sterility, or suitability for use.

Each result belongs to the named vendor’s certificate. Grades assess the document and its reported tests, not the vendor’s whole catalog or the safety of a product.
Automated checks can make mistakes. Open “Why this result?” for the reason and any review notice, and check the linked COA’s lot against your product. How grading works
