CJC-1295 (No DAC) Dosing & Reconstitution Calculator
Modified GRF 1-29, a short-acting GHRH analog often stacked with Ipamorelin.
TL;DR — CJC-1295 (No DAC) is a growth hormone peptide with a typical starting dose of 100 µg. For a 5 mg vial, add 2 mL bacteriostatic water to yield 2500 µg/mL.
Add 2 mL of bacteriostatic water to a 5 mg vial, injecting slowly down the inside wall. Swirl gently; never shake. This yields a concentration of 2500 µg/mL.
What is the recommended dose of CJC-1295 (No DAC)?
A typical research dose is 100 µg. Consult the ASCEND calculator for your specific vial concentration and draw volume.
How many doses are in a CJC-1295 (No DAC) vial?
A 5 mg vial reconstituted with 2 mL BAC water yields approximately 50 doses at 100 µg each.
Peptide Intelligence
What is the half-life of CJC-1295 (No DAC)?
CJC-1295 without DAC (Modified GRF 1-29) has a half-life of approximately 30 minutes, designed to mimic natural pulsatile GHRH release. It is injected before expected GH pulses, typically upon waking, pre-workout, or pre-sleep.
How does CJC-1295 (No DAC) differ from the DAC version?
The DAC (Drug Affinity Complex) version binds albumin and has a half-life of ~8 days for sustained GH elevation. The No DAC version has a ~30-minute half-life producing pulsatile GH bursts. The No DAC version is generally preferred when mimicking natural GH rhythms.
What is the optimal timing for CJC-1295 (No DAC) injections?
Optimal timing is in the fasted state to avoid insulin-GH antagonism. Common windows: 30–60 minutes before eating in the morning, pre-workout (90+ minutes post-meal), and at bedtime. The pre-sleep pulse is often considered most important for recovery.
