About CJC-1295 (No DAC)
Buy CJC-1295 No DAC 5mg at IGF1 Shop. CJC-1295 No DAC, also known as Modified GRF 1-29, is a 30-amino-acid analog of native growth hormone-releasing hormone with four amino acid substitutions that confer resistance to enzymatic degradation while preserving full GHRH receptor activity. Without the DAC linker, its half-life remains short (~30 minutes) — making CJC-1295 No DAC the standard pick for pulsatile GH release protocols and the canonical partner for Ipamorelin stacking. Every CJC-1295 No DAC 5mg vial is HPLC-verified at ≥99% purity, mass-spec confirmed, and accompanied by a per-lot Certificate of Analysis.

CJC-1295 (No DAC) — Mechanism & Specifications
CJC-1295 No DAC (Mod GRF 1-29) is a 30-amino-acid synthetic analog of native growth hormone-releasing hormone. Four amino acid substitutions confer resistance to enzymatic degradation while preserving full GHRH receptor activity. Without DAC conjugation, half-life remains short (~30 min) — ideal for pulsatile GH release.
Quality & release criteria
Every lot of CJC-1295 (No 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.

FAQ
CJC-1295 (No DAC) — Frequently asked questions
What is CJC-1295 No DAC?
CJC-1295 No DAC is a 30-amino-acid analog of GHRH, also called Modified GRF 1-29, with four substitutions that increase stability versus native GHRH. It binds the GHRH receptor on the pituitary and triggers a short, natural-shaped pulse of growth hormone. Without the DAC linker, its half-life is roughly 30 minutes, so it is dosed daily or split twice daily. Each IGF1 Shop vial contains 5mg of lyophilized peptide at ≥99% HPLC purity.
How is CJC-1295 No DAC different from the DAC version?
The No DAC version lacks the lysine-maleimidopropionic acid albumin linker, so it does not bind serum albumin and clears from circulation within hours. This produces a sharp, pulsatile GH release that closely mimics the body's natural rhythm, instead of the multi-day plateau seen with CJC-1295 DAC. Most users prefer No DAC when stacking with a GHRP like Ipamorelin or when they want fine control over timing.
What is the typical dosing protocol for CJC-1295 No DAC?
Common protocols use 100-200 mcg per injection, one to three times per day, taken on an empty stomach. Many users dose once before bed to ride the natural overnight GH pulse. Each 5mg vial reconstituted with 2mL bacteriostatic water yields 250 mcg per 0.1mL on a U-100 insulin syringe.
How should I reconstitute and store CJC-1295 No DAC?
Add 1-3mL of bacteriostatic water along the side of the vial, swirl gently, do not shake. Reconstituted vials store in the refrigerator at 2-8 °C and remain potent for roughly 4 weeks. Unreconstituted lyophilized powder is stable for two years at -20 °C protected from light.
What purity and testing does the vial ship with?
Every lot of CJC-1295 No DAC is HPLC-tested to ≥99% purity, identity-confirmed by ESI mass spectrometry against the theoretical 3,367.95 Da molecular weight, and endotoxin-screened by LAL to <0.5 EU/mg. The full Certificate of Analysis is issued by an ISO 17025-accredited laboratory and matched to the lot number on your vial.
How fast is shipping and what payment methods do you accept?
Orders ship discreetly worldwide; domestic orders over $59 ship free. Bitcoin, USDT, Ethereum, Monero, Litecoin, and major cards are accepted at checkout. Crypto orders are processed faster and qualify for an additional discount. Tracking is provided once your label is generated, usually within one business day.
