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 half-life visualizer.

Cycling

Typical cycles: 8-12 weeks on, 4 weeks off. Some use continuously.

Side effects & warnings

• 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.

Not a prescription, a dose, or a sourcing guide. CJC-1295 (without DAC) is a research compound; safety and efficacy in humans are not fully established, and research-grade material has no guarantee of purity, sterility, or stated strength. OptiPin is a tracking tool and does not recommend using research chemicals. Discuss any peptide with a qualified clinician.
