CJC-1295 NO DAC 5mg
Short-acting synthetic GHRH analog engineered to stimulate physiological, pulsatile growth hormone secretion in laboratory models.
Mechanism
Selectively binds pituitary GHRH receptors on somatotroph cells to trigger rapid, pulsatile secretion of endogenous growth hormone without continuous axis suppression.
Dosing
Standard investigational regimens begin at 100 mcg administered once daily, frequently evaluated prior to natural nocturnal surges.
Reconstitution
Reconstituting the 5 mg vial with 3.0 mL of bacteriostatic water yields an approximate working concentration of 1.67 mg/mL (16.7 mcg per U-100 unit).
Storage
Store the unmixed lyophilized powder refrigerated between 2 and 8 °C, and consume reconstituted liquid within 7 to 14 days under refrigeration or freeze aliquots below -20 °C.

Dosing Chart
| Phase / Day(s) | Dose & Frequency | Volume (U-100 units / mL) |
|---|---|---|
| Weeks 1–2 | 100 mcg (0.1 mg) once daily | 6 units (0.06 mL) |
| Weeks 3–4 | 150 mcg (0.15 mg) once daily | 9 units (0.09 mL) |
| Weeks 5–6 | 200 mcg (0.2 mg) once daily | 12 units (0.12 mL) |
| Weeks 7–10 | 250–300 mcg (0.25–0.3 mg) once daily | 15–18 units (0.15–0.18 mL) |
Reconstitution Steps
- 1
Draw 3.0 mL of bacteriostatic water into a sterile syringe.
- 2
Release it slowly down the vial's inner wall to limit foaming.
- 3
Swirl or roll gently until fully dissolved — don't shake.
- 4
Label with the date and concentration, then refrigerate at 2–8 °C (35.6–46.4 °F), shielded from light.

Overview
CJC-1295 without Drug Affinity Complex (DAC), commonly identified as Modified GRF 1-29, represents a truncated synthetic counterpart to endogenous growth hormone-releasing hormone. The sequence contains specific amino acid substitutions that grant improved resistance to enzymatic degradation relative to native GHRH, while omitting the reactive moiety that facilitates binding to serum albumin. Because of this structural profile, the compound exhibits an approximate half-life of thirty minutes. In laboratory models, this accelerated clearance produces discrete, transient peaks in somatotroph activity rather than sustained elevations, mirroring normal physiological pulsatility. Investigations often utilize this molecule to evaluate controlled endocrine pulses, often pairing it with complementary ghrelin mimetics to observe downstream effects on circulating IGF-1 concentrations. All data presented herein are derived from experimental literature for benchwork and educational documentation only. The substance is not approved for therapeutic administration, human consumption, or diagnostic procedures.
