Research vial labelled CJC-1295 without DAC, a Growth hormone secretagogue peptide studied in preclinical and clinical literature

CJC-1295 without DAC

Modified GRF 1-29

The file here is mostly preclinical work plus clinic and community practice, not registrational trials.

Short acting on purpose: protocols use it to mimic a natural pulse rather than hold levels up.

General profile

Class
Growth hormone secretagogue
Evidence
Mixed or moderate evidence
Studied dose range
0.1 mg
Frequency in protocols
1–3× daily, fasted
Route
Subcutaneous
Half life
~30 minutes
Reconstitution
2 mL bacteriostatic water per 5 mg vial
Storage
Refrigerated, ~30 days

Timing and cycling in the literature

Usually dosed in the bedtime window, fasted

One to three times daily, fasted

Deliberately short acting to imitate a natural pulse. Dosing it after food wastes the pulse entirely.

Reported cycle: 12 weeks on, 4 weeks off

Short acting by design, so protocols run in the same months-long blocks as sermorelin with a genuine washout.

Watch for: Injection site redness, swelling, and glucose drift.

What it conflicts with

Three separate questions, kept separate. A hard stop means the mechanisms must not run together at all and timing does not fix it. A syringe rule means the same day is fine but one barrel is not. Redundancy is not dangerous, it is paying twice to hit one target.

  • Hard stopTiming

    CJC-1295 without DAC + CJC-1295 with DAC

    Same compound, two release profiles

    One holds a plateau for days while the other pulses for half an hour. Running both means continuous stimulation on top of the pulse you were trying to preserve.

  • Pick oneRedundant, pick one

    CJC-1295 without DAC + Tesamorelin

    Same target hit twice

    Same GHRH lane. Pick the arm you want and titrate it.

  • Pick oneRedundant, pick one

    CJC-1295 without DAC + Sermorelin

    Same target hit twice

    Same GHRH lane.

  • Pick oneRedundant, pick one

    CJC-1295 without DAC + CJC-1295 with DAC

    Same target hit twice

    Same molecule with and without the albumin binder. One release profile at a time.

Most syringe compatibility claims here are practice and expert consensus, not peer reviewed mixing studies. A clear liquid after mixing does not prove the compounds are still active, and cloudiness, particles or gelling means discard. Active cancer, pregnancy, major cardiac care and heavy immunosuppression override every stack preference on this page.

The studies

Human trials: No completed human efficacy trial that establishes a dose for the use people are chasing.

Open questions: Treat published dosing as observed practice, not a validated protocol.
