Growth & Anabolic 5 mg / vial

CJC-1295 DAC 5mg (Long-Acting GHRH Analog)

Q: What does the "DAC" in CJC-1295 DAC mean?

DAC stands for Drug Affinity Complex — a lysine-maleimidopropionic acid linker attached to the C-terminus. The linker covalently binds serum albumin in plasma, shielding the peptide from rapid enzymatic breakdown. The result is a half-life of approximately 6-8 days instead of 30 minutes.

Q: How often do I dose CJC-1295 DAC?

Because of the extended half-life, CJC-1295 DAC is usually dosed once or twice per week at 1-2 mg per injection. A common starting schedule is 1mg every Monday and Thursday. Daily dosing is unnecessary and increases the risk of GH "bleed" — a continuous elevation that blunts natural pulsatility.

Q: CJC-1295 DAC vs No DAC — which should I choose?

DAC delivers continuous IGF-1 elevation with the convenience of weekly shots and is preferred for steady anabolic support. No DAC gives sharp, pulsatile GH release matching the body's circadian rhythm and is the standard pick when stacking with Ipamorelin. Choose DAC for simplicity, No DAC for physiological precision.

Q: What does each vial contain?

Each CJC-1295 DAC vial contains 5mg of lyophilized peptide, no fillers, sealed under inert gas. The 5mg pack covers roughly 2.5-5 weeks of standard weekly dosing depending on protocol.

Q: How is purity verified?

Each batch of CJC-1295 DAC is HPLC-tested to ≥99%, mass-confirmed by ESI-MS against the theoretical 3,647.16 Da molecular weight, and endotoxin-tested by LAL to <0.5 EU/mg. The per-lot Certificate of Analysis is issued by an ISO 17025 lab and downloadable on the product page.

About CJC-1295 (with DAC)

Buy CJC-1295 DAC 5mg at IGF1 Shop. CJC-1295 with DAC bioconjugates with circulating albumin via a maleimidopropionic-acid linker (the Drug Affinity Complex), dramatically extending its serum half-life from minutes to approximately 6-8 days. This makes CJC-1295 DAC suitable for once or twice weekly dosing instead of the daily pulsatile schedule of the No-DAC version. Every CJC-1295 DAC 5mg vial is HPLC-verified at ≥99% purity, identity-confirmed by ESI mass-spec, and accompanied by a per-lot Certificate of Analysis from an ISO 17025-accredited lab.

CJC-1295 (with DAC) — Mechanism & Specifications

CJC-1295 with DAC bioconjugates with circulating albumin via a maleimidopropionic linker, dramatically extending its in-vivo half-life. Used in protocols requiring sustained GHRH receptor activation rather than pulsatile stimulation.

Quality & release criteria

Every lot of CJC-1295 (with DAC) is released only after passing reverse-phase HPLC (≥ 99% area purity at 220 nm against a reference standard), ESI mass spectrometry confirmation of molecular weight, and Limulus Amebocyte Lysate (LAL) endotoxin testing below 0.5 EU/mg. The lot-specific Certificate of Analysis is provided with the order and available on request before purchase.
