CJC-1295 (without DAC): uses, dosing & the facts
A shorter-acting modified GRF peptide without the Drug Affinity Complex. Provides more frequent but shorter duration pulses of growth hormone. This is an evidence-graded reference – what it is, what it's used for, typical reported dosing, half-life, side effects, and how to track it. It is educational, not medical advice or a recommendation to use a research compound.
- • CJC-1295 (without DAC) – GHRH analog. A shorter-acting modified GRF peptide without the Drug Affinity Complex.
- • Commonly used for natural growth hormone stimulation, daily growth hormone optimization, muscle recovery and repair.
- • Half-life: Approximately 30 minutes.
- • Status: Research use only · not FDA-approved – an educational reference, not a dose protocol or sourcing advice.
What CJC-1295 (without DAC) is
A shorter-acting modified GRF peptide without the Drug Affinity Complex. Provides more frequent but shorter duration pulses of growth hormone.
What CJC-1295 (without DAC) is used for
- • Natural growth hormone stimulation
- • Daily growth hormone optimization
- • Muscle recovery and repair
- • Fat loss
- • Anti-aging effects
- • Improved sleep
These are reported/community uses, not proven clinical outcomes. Most research peptides have limited human trial data behind such claims.
Typical reported dosing
| Injectable | 100–300mcg per injection, 1–3 times daily injected subcutaneously before bed on empty stomach |
Presented as commonly-reported patterns for information only – not a dose recommendation. CJC-1295 (without DAC) dosing is a decision for a qualified clinician.
Reconstitution
Reconstitute 2–5mg vial with 2mL bacteriostatic water. 100mcg = 4 units. The arithmetic is the same for any peptide: concentration = vial mg ÷ water mL, and on a U-100 syringe 100 units = 1 mL. Compute your own vial with the reconstitution calculator.
Half-life & cycling
Half-life: Approximately 30 minutes. Half-life drives dosing frequency and how quickly the compound clears – see it plotted on the CJC-1295 (without DAC) half-life calculator.
Cycling
Typical cycles: 8–12 weeks on, 4 weeks off. Some use continuously.
Side effects & warnings
- an injection site that turns red, hot or hard, spreads, weeps, or comes with a fever – same-day medical care – research-grade material carries no sterility guarantee, so abscess and cellulitis are the documented consequence
- swelling of the lips, tongue or throat, trouble breathing, or widespread hives after a dose – emergency care
- new numbness or tingling in the hands, or hands and ankles that stay swollen – stop and get assessed – these are the classic signs of too much growth hormone signalling
- unusual thirst, or passing much more urine than normal – a blood-glucose check, since GH secretagogues raise it
- • Minimal side effects
- • Mild water retention in some
- • Less potent than DAC version but more frequent pulses
Requires daily injections. Must be taken on empty stomach. More frequent dosing than DAC version but shorter half-life. Good for users who prefer daily protocol control.
